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.

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.

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.

World Forum on Urban Forests: Call for trees to shape city planning

The first World Forum on Urban Forests will be held in Mantua, Italy from 28 November to 1 December 2018. This inaugural event will bring together experts from around the world – including urban foresters, arborists, planners, scientists, landscape architects and many other stakeholders – to discuss how to make cities greener, healthier and happier.

As well as launching long-term collaborations around the development of sustainable cities, the Forum will provide a perfect setting to showcase the best nature-based solutions that can be applied to urban environments. It will also be catalyst for calls to action, which have already begun in the lead up to the Forum.

Stefano Boeri, the architect behind Vertical Forests, is urging planners around the world to consider urban forestry as a core element of all city planning projects. Boeri, whose Milan-based architecture studio is making an impact in the sustainable building space, is best known for the incredible Vertical Forest project in Milan – a pair of award-winning twin towers covered in scrubs and floral plants. This project has become a model for ecological residential building, and Boeri now wants to engage all architects, designers and planners to integrate green spaces into their projects.

Boeri’s vision is for more than just sustainable architecture. It includes incorporating trees, gardens and woods as essential components for all projects. As well as providing visual beauty, urban trees bring many benefits that improve quality of life. These benefits include reducing CO2 emissions, improving air quality and protecting biodiversity.

Recent research shows that forests and trees absorb one fifth of carbon emissions produced by cities worldwide. Similarly, leaves and roots help reduce pollutants which contribute to respiratory diseases that kill 7 million people a year globally, according to the World Health Organisation. With around two thirds of the world’s population expected to live in cities by 2030, now is the time to start imagining new, greener urban landscapes. Particularly since urban areas currently account for more than 70% of global greenhouse emissions, despite covering only 2% of the world’s landmass.

“If a single tree can bring great benefits to the city and its inhabitants, an urban forest can be an extraordinary help to improve the quality of health and life in a city”, Boeri says.

Boeri will be one of many experts speaking at the World Forum for Urban Forestry. For more information on the Forum, visit the official website.
