Green Infrastructure is seen as expensive when compared to traditional grey infrastructure.

But with the increase of green infrastructure technology is this actually the case?

A study comparing the actual project costs to typical costs for conventional development found that 11 out of 12 diverse projects with direct cost comparisons between conventional and green infrastructure approaches showed cost decreases averaging 36%.

Green infrastructure, such as soil vaults and permeable pavement, can lower water treatment costs, reduce flooding, and erosion, thus providing economic and environmental benefits to the city.

What are the Typical Costs of Green Infrastructure Projects?

The cost of green infrastructure can be influenced by factors such as the type of project, location, and integration with planned infrastructure improvements.

Integrating green projects with planned infrastructure improvements, such as road reconstruction or roof replacements, can lead to cost savings of 30% to 60% over the lifetime of the project due to the multiple benefits that green infrastructure offers back to the built environment. 

It is important to note that the cost of green infrastructure is not solely determined by the initial construction costs but also includes life cycle costs, including planning, design, installation, operation and maintenance, and replacement. 

The cost-analysis of green infrastructure should be analyzed in conjunction with its performance and the multiple benefits it provides, including environmental, economic, and community benefits.

How do Cities Fund Green Infrastructure Projects?

Cities typically fund green infrastructure projects through a variety of mechanisms, including public and private sources. Some of the common funding sources and mechanisms highlighted in the search results include:

1. Public Sector Financing: Cities can use their main revenue sources, such as property taxes, transport fees, and other charges, to finance green infrastructure projects. They can also explore the greening of municipal financial instruments, such as congestion charges, variable parking fees, toll lanes, and split-rate property taxes, to achieve greener urban infrastructure1.
   
2. Private Sector Involvement: Public-private partnerships (PPPs) are a common mechanism for involving the private sector in funding green infrastructure projects. In PPPs, the long-term risk is transferred to the public sector, and they can play a significant role in financing and implementing green infrastructure projects1.
   
3. Grant Funding: Grant funding, including federal grants, can provide local governments with the resources to implement green infrastructure projects. However, federal grants can be highly competitive2.
   
4. Federal Programs: Federal programs that support efforts to reduce water pollution and manage stormwater can provide funding for green infrastructure projects. For example, the Environmental Protection Agency (EPA) provides funding for such projects.
   
5. Community Development Funds: Community development money can be used to fund green infrastructure projects because these projects can create jobs, increase economic activity, and increase property values. Urban tree planting and green infrastructure can increase economic activity in a commercial district and property values by mitigating flooding and improving neighborhood aesthetics3.
   
6. Transportation Funding: Green infrastructure projects are often eligible for transportation funding because they improve transportation networks by efficiently and cost-effectively mitigating street and alley flooding and create a cooler more comfortable environment for passengers.

A great way to ensure green infrastructure gets built is to set it as a building standard for new constructions and incorporate GI into street layouts and designs.

How To Do Green Infrastructure Cost Analysis?

To conduct a green infrastructure cost analysis, the following steps can be taken:

1. Define Green Infrastructure and Public Space: Green infrastructure is the network of green spaces, natural systems, and semi-natural systems that support sustainable communities, while public spaces are places publicly owned or for public use, accessible and enjoyable by all free and without a profit motive.
   
2. Cost Benefit Analysis: Measure incremental change relative to what would have happened without action, i.e., the base case. The CBA should only consider the incremental or marginal impact of a program or project. Specify the base case in as much detail as possible and quantify it to set a baseline for the incremental changes in outcomes that are being measured. including identifying the developing options, identifying and forecasting costs and benefits, valuing costs and benefits, identifying non-market impacts, and reporting the results of CBA.
   
3. Consider the Costs of Green Infrastructure and Public Space: The costs of such projects include construction costs, costs related to the replacement of capital, and costs related to ongoing maintenance and operation. Cost estimates should be specific to the individual project and reflect the design and conditions associated with the construction and operation of the project.
   
4. Value the Benefits of Green Infrastructure and Public Space: The benefits of public space are driven by a range of features, and the framework provides recommended approaches and parameters for valuing these benefits. It’s important to carefully consider the specific benefits associated with the project and apply the recommended parameters accordingly.
   
5. Engage with Stakeholders: In addition to using the framework, practitioners should engage with stakeholders, including the department’s subject matter experts and the community to understand the full use case of the infrastructure.

By following these steps, practitioners can conduct a comprehensive green infrastructure cost analysis that takes into account the economic, social, environmental, and cultural costs and benefits of the project.

What are the Benefits of Green Infrastructure?

There are a multitude of benefits related to green infrastructure that cities that consistently invest in green infrastructure are seeing.

Energy Efficiency

Green Infrastructure reduces the cooling demands of households, and buildings through creating shade and transpiration of water through leaves from trees and plants. The NSW government estimates that for each reduction in degree through tree canopy you decrease your energy bill by $13.

Air Quality Improvement

Increasing tree canopy and urban green walls contribute to air quality improvement through capturing of physical and gaseous pollutants, suspending captured particles, emitting environmentally friendly particles like pollen, and disrupting of wind flows through tree canopy.

Water Management

Green Infrastructure can capture water runoff, which reduces the volume of stormwater that needs to be processed and be used to sustain the green infrastructure itself. It additionally improves the water quality of runoff that does reach the waterways.

In the ‘Valuing green infrastructure and public spaces Framework’ from the NSW Government. The estimate the value of stormwater reduction based on the avoided costs of projects to build additional stormwater management infrastructure like wetlands and retention ponds.

Some key data points from that analysis:

• Cost to manage stormwater flows ranged between $0.04 to $0.30 per cubic metre captured, depending on the type of infrastructure option
• An average-sized street tree in Canberra captures 16,500 L (16.5 cubic metres) annually
• A hectare of irrigated urban forest would capture 1 megalitre (1,000 cubic metres) of stormwater per 20 mm rain event

So in summary, the document states green infrastructure and trees can reduce stormwater runoff, avoiding the need for additional “grey” stormwater infrastructure. This avoided expenditure provided an approach to quantifying the stormwater management benefits.

Health Benefits

Green Infrastructure has far ranging impacts in the areas of mental and physical health. Increasing the amount of green infrastructure in the forms of public open spaces, parks, and facilities shows a 6% increase of residence hitting their daily activity goal which equals around a $1.13 cost saving per household per km walked.

Urban cooling through tree canopy and transpiration also reduces heat-related health complications. The NSW Government estimates 1°C of cooling saves $3 per person per very hot day in health costs and an 10% increase in canopy cover is equal to a 1.1°C cooling effect.

We invited General Practitioner Dr. Kim Loo to come speak at our event ‘Where Shade hits the Pavement’ to discuss how trees and urban planning are impacting her patients in Western Sydney.

Takeaway

Despite its complexity, the wide-ranging benefits of green infrastructure unfold gradually over time. While there exists an initial upfront cost during the construction phase, this investment quickly shows substantial returns, growth and impact for the community.

As the effects begin to manifest in the economic, social, and environmental spheres, the return on investment becomes increasingly evident. The transformative power of green infrastructure becomes apparent when measuring its positive influence on economic savings, social well-being, and environmental sustainability.

Therefore, while the initial costs might seem substantial, the long-term advantages and dividends gained from the implementation of green infrastructure undoubtedly outweigh these initial expenses, making it a wise and forward-thinking investment for communities and regions alike.

In urban and suburban settings, trees can provide shade and beauty, but their roots often pose a significant threat to pavements, causing unsightly and hazardous uplifts. This guide explores effective strategies to prevent and address pavement lift from tree roots. Learn how to protect your hardscape, ensure safety, and maintain curb appeal while ensuring your trees are an actual benefit to your urban space.

What is Pavement Lift?

Pavement lift refers to the situation where sections or segments of paved surfaces, such as roads, sidewalks, or driveways, are raised or uplifted unevenly and has been displaced from its original position due to external factors.

What is Root Heave?

Root heave is a phenomenon where tree roots beneath the ground exert upward pressure as they search for nutrients, water and oxygen, causing pavements and urban infrastructure like sidewalks and driveways to lift and crack. This can lead to safety hazards and aesthetic issues, making it crucial to understand and address how to plant a tree to avoid root heave

How to Stop Root Heave?

Preventing root heave is far more effective and cheaper than dealing with it after the fact. By adopting the right strategies and planting techniques below, you can avoid the costly upheaval and damage caused by tree roots, ensuring the longevity of your pavement.

Ways to Prevent Tree Roots Causing Pavement Lift

Safeguarding your sidewalks from tree root damage requires a thoughtful proactive approach before the tree is even planted in the ground. Below we’ve detailed several methods that can be employed to prevent tree roots from undermining the stability of your pavement and urban infrastructure.

Use Soil Vault Systems

Using Soil vaults systems otherwise known as soil cells such as those developed by Citygreen allow tree roots to grow in ideal growing conditions while protecting surround infrastructure from tree root disturbances.

A top use case for soil vault systems is that it is rated for vehicle loads so it’s great for street pavements, carparks, and stormwater management.

Proper Positioning of your Trees

Choosing the right location for tree planting is essential to prevent root-related problems. Proper positioning can minimize conflicts between tree roots and sidewalks, leading to a harmonious coexistence.

Properly positioning trees to avoid pavement lift and reduce conflicts with sidewalks and pavements is a critical step in urban tree management. Start by selecting tree species with non-invasive root systems, and consult with local experts for guidance. Reach out to your local government parks department or urban forester as they will be more then happy to send you a list of trees that are ideal for growing in your local climate.

Maintain a safe distance of at least five to ten feet between the tree base and nearby hardscape, allowing roots to develop without initially compromising pavement stability. Analyze soil conditions to ensure well-draining soil with adequate organic matter, which encourages healthy root growth away from pavements. We recommend using loamy soil but you can see our article on choosing the best soil for your tree here.

Plant trees at the right depth, avoiding shallow planting that may lead to horizontal root spread and deeper planting to promote root growth away from the surface. Regularly monitor root growth patterns and consider professional assistance to assess local conditions and choose suitable species and planting techniques. Well-structured tree pits with features like root barriers and proper drainage can direct root growth downwards away from infrastructure, ensuring a harmonious coexistence.

Related: How do Tree Roots Behave?

Bridging

Bridging is a technique that creates a buffer zone between tree roots and pavements. This method involves installing materials that allow roots to grow beneath the sidewalk without causing upheaval. Creating a slope for your sidewalk involves the strategic use of posts, piers, or arch supports. These supports serve as the foundation for laying the sidewalk material, leaving deliberate space for the roots to grow beneath without causing disruptions.

One notable benefit of root bridging is its capacity to preserve existing tree roots, ensuring their continued health and enhancing overall stability. The choice of bridging materials can vary based on specific project requirements, including desired height, repair area length, and available budget. Commonly employed materials encompass wood, concrete, and composite materials.

However, it’s important to note that the design and construction of root bridging can be a relatively costly endeavor. In cases where the bridge elevation aligns with a typical step height (approximately 6 to 8 inches) relative to the surrounding grade, the installation of safety railings may be necessary. In certain scenarios, the incorporation of soil can be employed to seamlessly blend the bridge edge with the surrounding terrain, effectively eliminating any abrupt step-off points.

As root bridging can be expensive and incorporate alot of safety factors, it’s better to plan your tree planting to ensure that the trees roots have the best chance of growing deeper to never distrub the surface.

Root Barriers

Barriers such as Root Directors or Reroot Barriers are a great preventative measure designed to direct and guide exploring roots down and away from services and infrastructure. They are best installed when the tree is newly planted so when the roots expand and reach the barriers they will be directed deeper into the soil instead of staying in the upper levels of the soil.

Installing Snorkils also help greatly in enticing the tree roots to explore downwards to help avoid pavement lift as the Snorkil gives access to oxygen and water at a lower depth so the roots don’t have to keep near the surface to access the nutrients it needs to survive.

Reinforcing Collars

Similar to Root Barriers reinforcing sidewalks with concrete collars or gravel aggregate helps deter tree roots from growing beneath them, thus preventing damage and upheaval.

Additionally, adding a layer of compacted gravel or pebbles beneath the sidewalk can create a path for tree roots to follow, reducing the likelihood of pavement damage as tree roots prefer to grow in the path of least resistance.

e.g. Trees roots grow faster in uncompacted soil when compared to compacted soil due to the tree having to expend less energy to push through the soil in search of oxygen, nutrients, and water.

Tree Removal

In cases where tree roots pose an imminent threat to pavements, roads or infrastructure; where there is direct safety issues involved, tree removal or relocation may be a necessary but last resort option to prevent further damage.

What to Avoid When Dealing with Tree Roots

Understanding what not to do when dealing with tree roots is as crucial as knowing the right techniques. Certain actions can exacerbate the problem and lead to more significant damage.

For example, removing too much of a tree root could create a void space that can no longer support the above pavement which cause create further issues.

Tree Care Services Can Help Prevent Damage to Your Property

Professional tree care services can provide expert guidance and assistance in managing tree roots and preventing damage to your property. Their expertise can be invaluable in maintaining both your trees and pavements.

Tree Roots Pushing Up Driveway – What To Do

If tree roots are causing your driveway to heave and crack, specific actions can help address the issue, restoring the functionality and appearance of your driveway.

First Signs of Tree Root Damage

Recognizing the early signs of tree root damage is essential to address the issue promptly.

The initial signs of tree root damage to pavements and driveways can vary depending on the severity of the issue, but common early indicators include cracks, uneven surfaces, and pavement shifting.

The most noticeable sign of such damage is often cracking or sections of pavement lift that are uneven or lifted. These issues can pose trip hazards and make walking or driving difficult.

In some cases, instead of uplifting, the pavement may sink or settle due to soil erosion caused by root growth. As roots expand beneath the pavement, they can create an uneven surface or pockets of air below the pavement and make it challenging to walk or drive smoothly.

Advanced cases may even reveal visible tree roots breaking through the pavement surface or pushing it upwards. Additionally, the pressure from tree roots can not only damage the pavement but also lead to cracks in nearby structures like retaining walls, curbs, or foundations.

Plan Ahead to Avoid Tree Root Damage to Urban Infrastructure

Effective planning and design are key to avoiding tree root damage causing pavement lift. By taking precautions during the initial stages, you can prevent future issues.

Kill the Tree Root with Copper Sulfate

Copper sulfate, a cost-effective herbicide and algaecide, is commonly used to clear tree roots from sewer lines and pavements. However, before use, check local regulations due to its potential toxicity and environmental impact. Inspect your local area to assess the root infestation’s severity. Be cautious around pets, as it can be toxic to animals.

Test the sewer line by flushing the toilet, and repeat treatments if needed. Periodically flush copper sulfate to prevent new root invasions, and consult various references for further information on its use.

Remove the Root

Removing the offending tree root is a direct but sometimes necessary solution to eliminate damage and upheaval caused by tree roots. ensure the structural integrity of the tree isn’t compromised.

Trees provide numerous benefits to the urban environment, including enhancing air quality, reducing stormwater runoff, and providing shade and habitat for wildlife. In this section, we will explore how landscape architects plant trees and the techniques they use to ensure their success.

Key Takeaways:

• Landscape architects play a crucial role in planting trees to create sustainable and healthy environments.
• Proper selection of tree species, planting techniques, and maintenance are essential for the long-term health of trees.
• Landscape architects navigate unique challenges when planting trees in urban environments.
• By following best practices in tree planting, we can contribute to a greener and healthier future.

The Importance of Tree Planting for Urban Landscapes

Tree planting is an essential component of creating sustainable and healthy environments, especially in urban areas. Landscape architects follow best practices to ensure the successful establishment and growth of trees, including sustainable tree planting and urban tree planting.

One of the critical tree planting best practices is selecting appropriate tree species. Landscape architects carefully choose the tree species that are well-suited to the local climate and site conditions. They prefer native tree species as they provide numerous benefits, such as supporting local wildlife and improving biodiversity.

Soil and tree root preparation is crucial for sustainable tree planting. Landscape architects use innovative techniques like soil cells, such as Stratavault or soil vault systems, to ensure adequate space for root growth and improve soil quality. This is especially important in urban areas where soil compaction and pollution can be a significant challenge.

Tree roots are opportunistic, seeking out favorable growing conditions. Moisture trapped beneath impermeable pavements, oxygenated sand layers, moist conditions in service trenches, cracks in road pavements and curbs- these are some areas that tree roots will explore to satisfy the life needs of the tree which leads to pavement and infrastructure damage.

Landscape architects also employ various tree planting techniques to ensure proper tree planting. This includes preparing the hole properly, handling the root ball, and planting the tree at the correct depth. These techniques promote healthy root development and establish strong trees.

Proper maintenance is crucial for the long-term health of planted trees. Landscape architects monitor the trees for signs of stress, pests, or diseases. They provide necessary pruning, fertilization, and irrigation to ensure optimal growth and resilience. Moreover, they also consider factors like site conditions and tree spacing to optimize the tree’s health and longevity.

Overall, landscape architects prioritize sustainability in tree planting projects to ensure that the planted trees contribute to a resilient and environmentally friendly landscape. By following their best practices, we can contribute to a greener and healthier future.

Selecting Tree Species for your Landscape

When it comes to planting trees, landscape architects carefully consider which tree species to select. Native tree species are often preferred, as they are better adapted to the local climate and conditions and can provide numerous benefits. In fact, selecting the right species can make all the difference in the success of a tree planting project.

Native trees also support local wildlife and improve biodiversity. They are often hardier than non-native species, able to withstand harsh weather conditions and local pests and diseases. Additionally, native species are more likely to support the specific ecology of the area, including pollinators like bees and butterflies.

Related: Best Species for Reducing Air Pollution

However, it’s not just about selecting native species. Landscape architects also take into account factors such as tree growth rate, size, and appearance to ensure the right tree is selected for the right location. They also consider the soil conditions and water availability, as well as any potential hazards that may impact the growth of the tree.

By carefully selecting the appropriate tree species, landscape architects can create healthier and more resilient urban forests. Not only do these trees provide environmental benefits, but they also contribute to the beauty of our urban landscapes.

Tree Planting Techniques

Proper tree planting techniques are essential for successful tree growth and development. Landscape architects utilize various methods to ensure optimal tree health.

One crucial technique is proper hole preparation. The hole should be dug to the appropriate depth and width, allowing enough space for the roots to spread out. The root ball should be handled carefully to prevent damage. The edge of the root ball should be lightly hand brushed to bring all the fine roots out and larger structural roots at the edge of the root ball should be pruned if their roots are facing inward to avoid root swirl. We do this to ensure once the tree is planted in it’s new surroundings new growth is focused on growing outwards into new soil.

Correct planting depth is also important. The topmost root of the tree should sit slightly above the soil level to prevent it from suffocating. After planting, the soil should be carefully compacted to eliminate air pockets and provide support for the young tree.

Overall, landscape architects should follow specific tree planting methods that ensure the long-term success of the planted trees.

Soil Preparation and Soil Cells

Landscape architects understand the critical role of soil preparation in ensuring successful tree planting. They use innovative techniques like soil cells to improve soil quality and provide adequate space for root growth, promoting healthy trees.

Related: How much Soil do Street Trees Need?

Soil cells are a specially designed system that provides structural support for pavements and surfaces while simultaneously providing ample space for root growth and water drainage. Stratavault and soil vault systems are examples of these systems that feature an interlocking matrix design that creates ideal conditions for soil moisture and movement.

Advantages of Soil Cells	Disadvantages of Soil Cells
* Improved soil structure and quality * Prolonged tree lifespan * Enhanced stormwater infiltration and drainage * Reduced soil compaction and increased porosity * Prevents root damage from construction or digging * Lower lifetime maintenance cost of surrounding infrastructure	* High initial installation cost

By using soil vault systems such as those created by Citygreen, landscape architects can promote healthy tree growth and create sustainable landscapes that benefit both the environment and the community.

Top Benefits of Planting Urban Trees

The benefits of planting trees in urban areas are numerous and far-reaching. Trees help to improve air quality by absorbing pollutants such as nitrogen dioxide, sulfur dioxide, and fine particulate matter. They also help to sequester carbon, which is important for mitigating the effects of climate change.

Additionally, trees help to reduce the urban heat island effect, which occurs when cities are significantly warmer than surrounding rural areas due to the heat absorbed and reflected by buildings, pavement, and hardscaped surfaces. Trees combat the heat by providing shade and evapotranspiration, which helps to cool urban areas and reduce the amount of energy required for air conditioning.

Urban trees help increase biodiversity and support local ecosystems, providing habitat for wildlife, including birds, insects, small mammals, and clean the surrounding soil and air of pollutants and particulates. This is especially important in urban areas, where natural green space is often limited and runoff from hardscaped surfaces, infrastructure and cars has detrimental effects to the community.

How to Grow Better Urban Trees

Hear from Ross Clark, the man who wrote the standard on growing trees in Australia. Ross Clark recently spoke at our event ‘Where the Shade hits the Pavement’ on how to grow better urban trees.

Identifying Suitable Areas for Planting Trees in Urban Areas

Identifying suitable planting locations is an important step in planting more trees in urban areas. Areas that lack greenery and could benefit from more trees include parks, sidewalks, residential areas, and public spaces.

For example, Penrith City Council in Australia identified suitable areas to plant urban trees by using heat sensor data, topography mapping and community survey data to review where the most vulnerable in their community lived to determine areas where additional tree canopy cover would be most beneficial and prioritized planting in those locations.

You can review Penrith City Councils full ‘Cooling the City Strategy’  from our Where Shade Hits The Pavement Event here:

How to Choose a location for Urban Trees?

When choosing planting locations, it is important to consider factors such as accessibility, sunlight, and available soil volume and quality. Trees should be planted in areas that are easily accessible for maintenance and receive adequate sunlight, water and soil volume.

Soil volume and quality is absolutely crucial to the success and longevity of urban trees, as trees require well-draining soil that is rich in nutrients and uncompacted to provide space for root growth and oxygen and water the chance to peculate deep into the soil.

In urban areas where soil volume and space is a concern, Citygreen’s leading range of structural soil vault systems are designed to provide adequate growing medium for tree roots, infrastructure protection, and provide additional green blue stormwater management properties (WSUD) all within one system.

When selecting tree species, it is important to consider the size of the tree at maturity, as some species may be too large for urban areas and cause damage to the tree, buildings and infrastructure.

There is nothing more disheartening than witnessing a tree’s canopy hacked to accommodate utilities like powerlines due to poor planning. In such instances, both the tree and the community suffer, missing out on the invaluable benefits of a mature tree in the environment.

Moreover, the mismanagement of trees results in wastage of ratepayers’ money, as maintenance workers must continually tend to the space surrounding the infrastructure for the total lifecycle of the tree.

Factor to Consider	Examples
Tolerance to pollution	London Plane Tree, Eastern Red Cedar, Ginkgo, Honey Locust
Drought tolerance	Hackberry, American Elm, White Oak, Redbud
Soil compaction tolerance	Red Maple, White Pine, Black Cherry, Bald Cypress
Mature size	Japanese Maple, Crape Myrtle, Dogwood, Serviceberry

Planning the Urban Tree Planting Process

Best Time to Plant a Tree

Planning the tree planting process involves several important steps. The ideal time to plant a tree is during autumn after trees lose their leaves or early spring before budbreak.

We ideally plant during autumn as tree root growth goes into overdrive, instead of the tree splitting its energy between root growth and canopy growth the tree focuses on expanding it’s fine and structural roots as far as possible when canopy growth is much less of a concern.

The further the fine and structural roots grow and establish, the better the outcomes the tree canopy will experience during the following canopy growth period.

What Soil Should you use for Urban Trees

The type of soil you use and soil preparation is also important to the success of trees in urban areas, as trees require well-draining uncompacted soil that is rich in nutrients.

Proper irrigation is necessary to ensure that newly planted trees receive enough water to establish healthy root systems. At Citygreen we can provide customised soil designed specifically for the trees environment.

Citygreen invited landscape architect Elke Haege Thorvaldson, co-author of the acclaimed ‘Soils for Landscape Development‘ to speak at ‘Where the Shade Hits the Pavement’ about how to design and specify soils for trees in urban locations.

Proper Urban Tree Planting Techniques 

When planting the tree, ensure it is positioned at the proper height and the root crown is at ground level, and the hole is dug to the correct depth to avoid oxygen deprivation that hinders root development.

Confirm the tree stands straight by using a tree anchor and having someone view it from multiple angles before backfilling the hole gently yet firmly, stabilizing the root ball’s base with packed soil. Eliminate air pockets by watering periodically during backfilling.

Only stake the tree if necessary, as studies show that unstaked trees establish faster and develop stronger trunks and roots. Mulch the tree’s base with organic matter to retain moisture, moderate soil temperature, and reduce weed competition.

Newly planted trees in urban areas need additional care during their initial establishment phase. Addition follow-up care is needed in the weeks after such as keeping the soil moist but not waterlogged, watering trees at least once a week, and more frequently during hot and windy weather.

Water must be concentrated on the rootball at the base of the tree as a newly-planted tree can only access moisture that is within reach of it’s roots. We recommend installing a Snorkil system around a newly planted tree to help water & oxygen access the deeper roots. The Snorkil also helps avoid roots trying to surface in search of nutrients as the deeper roots have access to a deeper source of food.

Engaging the Community in the Tree Planting Process

Community engagement is an important aspect of tree planting initiatives in urban areas. Involving the community in these initiatives can help to increase awareness and support for environmental conservation efforts.

Ways to encourage community participation include hosting public events, working with local organizations, and providing educational resources on the benefits of trees and how to care for them. Community members can also be involved in the selection of tree species and planting locations. 

Reach out to your city council and see if they offer a free tree planting program.

Maintaining Planted Trees in Urban Areas

Proper maintenance is crucial for the health and longevity of planted trees in urban areas. Regular watering is necessary to ensure that trees receive enough moisture, especially during hot and dry periods. Pruning is important to remove dead or damaged branches and promote healthy growth.

Monitoring for pests and diseases is also important, as urban environments can be conducive to the spread of these issues. It is important to address any issues early to prevent them from spreading and causing damage to the trees.

Monitoring the Impact of Urban Tree Planting on the Environment

What gets measured gets improved. Measuring the impact of tree planting initiatives in your community is crucial. This involves monitoring the reduction of air pollution, the increase in biodiversity and health of the tree, heat measurements, property values, and increased community activity.

By tracking progress, you can determine the monetary and environmental value these trees bring to the community.

Overcoming Challenges in Planting More Trees in Urban Areas

There are several challenges to planting more trees in urban areas, such as lack of space and limited funding or initiative by developers, council . However, there are solutions to these challenges:

City Mandated Tree Plantings for new Constructions: New Constructions and developments must include a minimum number of trees in their designs to ensure that any new constructions are adding environmental value to the community to help combat climate change, and the urban heat island effect.

City Mandated Soil Volumes: Soil Volume is critical to the success of urban trees so city standards must include a minimum soil volume that is adequate for trees to survive once they reach maturity. 

Maintenance Programs: Ensuring the continued care and maintenance of newly planted trees is vital for their survival and growth. However, a challenge arises with tree ownership, responsibility, and care, particularly when dealing with project-based constructions focused on swift project completion and tight deadlines.

It is crucial to establish maintenance programs during the initial contract process. By doing so, we can guarantee that the development and success of the trees are not overlooked or disregarded after the initial planting phase. 

Case Study: Stratavault Empowering Tree Planting in Tamworth CBD

Tamworth CBD’s bustling Peel Street serves as a central hub, attracting visitors from distant towns and farmers for work and leisure.

Social Benefits of Trees in Cities

The presence of tree canopy has significant social benefits that enhance the quality of life in urban areas. One of the most noticeable benefits is the aesthetic appeal that trees bring to our cities. They soften the harshness of concrete landscapes, adding natural beauty and a sense of tranquility. The sight of vibrant green leaves and colorful blooms uplifts our spirits and creates a welcoming environment for residents and visitors alike.

Trees also contribute to improved mental health and well-being. Studies have shown that spending time in nature, even in urban settings, can reduce stress, boost mood, and enhance cognitive function. The presence of tree canopy provides a natural escape from the hustle and bustle of city life, offering a peaceful retreat where people can relax, rejuvenate, and reconnect with nature.

Furthermore, trees foster a sense of community and social cohesion. They create gathering spaces and opportunities for outdoor activities, such as picnics, concerts, and recreational sports. These communal spaces foster social interactions, strengthen community bonds, and promote a sense of belonging.

Medical Health Benefits of Trees in Cities

The presence of abundant greenery in urban settings is not just an aesthetic luxury but a medical necessity. Tree canopy serve as natural air purifiers, tirelessly filtering out harmful pollutants and particulates from the air while releasing oxygen, creating a cleaner, fresher atmosphere that promotes respiratory health. Research has shown that neighborhoods with ample tree cover experience lower rates of respiratory issues and allergies, providing residents with a breath of fresh, clean air right outside their doors.

Furthermore, the soothing presence of trees and the shade they offer play an indispensable role in managing the mental health of city dwellers. The tranquility and psychological comfort they provide are invaluable, reducing stress levels and promoting emotional well-being. The simple act of walking beneath a canopy of trees has been proven to alleviate stress, anxiety, and depression, offering respite from the hustle and bustle of urban life.  In recent years the Japanese practice of Forest Bathing or Shinrin-yoku has grown in popularity and has shown to have positive health benefits with more doctors subscribing it as a treatment.

Extreme heat also disproportionately affects our most vulnerable, including the elderly, children, those with chronic illnesses, and people with limited resources. These groups face a heightened risk of heat-related illnesses, exacerbated chronic conditions, and potential medication interactions. Limited mobility, social isolation, inadequate housing, and financial stress further compound their vulnerability. 

Mitigation of urban heat islands, characterized by elevated temperatures due to the abundance of hard reflective surfaces and limited vegetation, can lead to heat-related illnesses and exacerbate chronic conditions. Tree canopies provide a natural shield against the sweltering heat. They offer crucial shade, cooling the surrounding areas and reducing heat stress among residents.

Related: How to Lower Urban Heat With Tree Canopy

By mitigating the urban heat island effect, trees become our frontline defense against heat-related health issues, such as heat exhaustion, dehydration, and even more severe conditions like heatstroke. Moreover, the cooling effect of trees extends indoors, reducing the demand for energy-intensive air conditioning, which not only conserves energy but also lessens the financial burden on individuals and public health systems.

In essence, the presence of trees in urban settings isn’t just an aesthetic choice; it’s a lifesaving measure that we must prioritize for the well-being of our urban populations.

Economic Benefits of Trees in Cities

Beyond their environmental and social contributions, tree canopy also brings significant economic benefits to urban areas.

At Citygreen, we believe that trees can help to alleviate the impacts of climate change, but first, we need to get them in the ground, so they thrive in our communities.

Planting trees in our bustling cities is no easy feat. The idea that you can plant a tree into a sidewalk or verge and hope that it will survive on its own during these erratic weather seasons we now face is an idea that has now been conclusively abandoned.

So what tree management options are available to ensure trees in urban settings have the best chance to grow into productive life long assets?

At Citygreen, we believe that planting trees using an adequately designed root management system is a small cost compared to the time and labour needed to replant trees and landscapes after premature death or removal due to infrastructure damage.

What is a Root Director?

Root Director is a circular root management device designed to prevent root swirl and divert root growth downward and outward away from surround urban infrastructure such as roads, and pavements. The root director sit over the trees rootball and encourages controlled root growth, which enhances the tree’s growth and overall longevity and stability.

Why you should use a Root Director for your next Tree

This innovative solution provides numerous benefits that support optimal tree growth and overall tree well-being. Here’s why you need a root director for your trees:

Enhanced Root Guidance:

A root director directs the growth of tree roots downwards directly from the root ball, guiding them away from potential obstacles such as utilities, sidewalks, or structures. This ensures that roots can expand freely in a controlled manner, reducing the risk of damage to infrastructure and promoting healthy root development.

Improved Nutrient and Water Uptake:

By directing the roots towards nutrient-rich soil and water sources, a root director optimizes the absorption of essential nutrients and moisture by the tree. This results in improved tree health, increased resistance to stressors, and enhanced overall growth.

Prevents Root Circling and Girdling:

Without proper guidance, tree roots may start circling or girdling around the tree’s own trunk, leading to restricted water and nutrient flow and eventually compromising the tree’s stability and health. A root director prevents such issues by redirecting the roots outward, promoting a strong and well-structured root system..

Preserves Landscape Design:

In urban and landscaped areas, maintaining the intended design and aesthetic appeal is crucial. A root director allows trees to grow in a more controlled manner, preserving the desired landscape design while ensuring the trees’ long-term health and structural integrity.

Long-Term Tree Care:

Incorporating a root director as part of your tree care strategy promotes proactive and sustainable tree management. It helps minimize the need for root pruning or disruptive maintenance practices in the future, saving time, effort, and costs associated with tree care.

Investing in a root director is a proactive measure that supports the vitality and longevity of your trees. By guiding root growth and providing essential benefits, it’s a valuable tool for maintaining healthy, robust trees that contribute to the beauty and sustainability of your landscape.

Deeper and healthier root growth means the trees can access more subsoil moisture during dry periods. During wet periods, the roots have a greater and deeper span to find available oxygen in waterlogged soils.

Also, if tree roots are not directed downwards, they will grow horizontally and cause issues to other infrastructures like pipes and sidewalks.
