A Guide to Safeguarding Our Urban Forests

Urban trees and building work

Safeguarding a tree, or advocating for its preservation, is a valuable effort and in cities, where our activities are already causing harm to green infrastructures, it is more important than ever. Urban forests represent the entire network of trees, vegetation, and associated ecosystems within our towns and cities.

As our urban areas continue to expand at unprecedented rates, we face a critical juncture in the preservation of these essential resources. The challenge lies in striking a delicate balance between necessary urban development and the preservation of our urban forests, which are crucial components of sustainable city planning. To celebrate National Tree Week, which runs from 27th November until 5th December, here is how we can protect our urban forests for the future.

Challenges in urban forest conservation

Protection during construction

Much of the damage that occurs to urban forests comes from development, feasibility studies, and all types of building work. Construction activities such as digging trenches, compacting soil, and laying foundations can damage or destroy tree roots, leading to reduced water and nutrient uptake, instability, and, ultimately, the death of the tree. This then also leads to the removal of trees and the loss of green spaces, reducing habitat for wildlife and affecting local ecosystems.

Trees potentially affected by construction should be evaluated by a certified arborist, who can determine whether preservation or replacement is the better option. Tree protection strategies should be clearly outlined early on in construction plans and specifications before construction begins. Any exposed tree roots during the process also need to be promptly covered and kept moist until final backfilling and soil placement can occur.

Development pressures

As urban areas expand, the pressure to use every inch of available land becomes increasingly intense. Rapid population growth, coupled with a rising demand for housing, infrastructure, and commercial development, drives a relentless pursuit of space within our city boundaries. Likewise, high land values and the economic incentives associated with development often lead to the perception of trees and green spaces as barriers to progress rather than valuable assets.

Whether it is large-scale housing blocks or private residential renovations like a garage extension, builders and planners are tasked with the challenging responsibility of balancing the need for new construction with the imperative to preserve green spaces. For urban planners, they also have the added pressure of integrating greenery into city landscapes with minimal damage. This balancing act is complicated by competing interests: developers may prioritise financial returns, while environmental advocates emphasise the need for green spaces for community wellbeing, climate regulation, and biodiversity.

Administrative challenges

Urban trees often fall under the scope of several entities, such as governments, private property owners, and utility companies, each with their own differing priorities and responsibilities. This can lead to inconsistent policies and practices, making it challenging to implement cohesive strategies for the protection and maintenance of urban forests.

Budget constraints further complicate these efforts, since funding for tree care and preservation is often limited or deprioritised in favour of other more seemingly pressing needs. Without adequate financial resources, essential activities like pruning, pest management, and the replacement of damaged trees are frequently neglected, resulting in a decline in the health and longevity of urban forests.

Strategic solutions for tree conservation

Sustainable building integration

The use of sustainable building materials plays a crucial role in overall environmental conservation efforts, especially for trees. Innovative materials and techniques can often provide alternatives that better complement existing tree preservation goals. Where wood is required, Forest Stewardship Council (FSC)-certified wood ensures that the timber used comes from responsibly managed forests, while recycled and eco-friendly materials reduce the overall environmental impact of construction.

Sustainable building design should also consider its impact on existing trees from the earliest stages. This includes optimising building footprints to minimise tree removal, incorporating permeable surfaces to maintain natural water flow, and integrating green infrastructure elements to the design itself.

Policy and regulation framework

It is vital that comprehensive tree preservation ordinances outline clear requirements for tree protection during development, including specific measures for heritage trees and significant specimens. These permits should mandate tree protection plans, while compensation and mitigation policies ensure that unavoidable tree removal is offset by meaningful replacements or conservation efforts elsewhere.

But it is not just protection that is important, but creating policies that encourage more growth to increase canopy cover in our neighbourhoods. Denser urban canopies can provide cooling, better microclimates, and a boost to residents’ mental and physical health. Cities like London are already paving the way by taking steps to introduce more parks and green spaces that will enhance the city.

Managing risks and diseases

The swift spread of pests and diseases poses a significant threat to urban forests. Implementing effective monitoring and early detection strategies can help save millions of pounds in mitigation costs. Trees not only age and require ongoing care, including pruning and removal, but they also face challenges from our shifting environmental conditions. These changes extend beyond climate to include alterations in the surrounding built environment. Both new developments and ageing infrastructure can influence tree health, growth, and overall distribution.

Community engagement and education

Successfully conserving our urban forests requires active participation from stakeholders, first and foremost. Public consultation processes should gather community input early in development planning. Similarly, developer education programmes can help build an understanding of tree preservation techniques and the benefits of doing so.

Community stewardship initiatives allow for longer term involvement in caring for and monitoring our urban forests too. The more we invest in professional training, the more we can ensure that contractors and professionals understand and implement proper tree protection measures.

Lastly, effective communication is essential for building support for urban forest conservation. Public awareness campaigns should highlight the multiple benefits of urban trees and the importance of their care and protection for future generations. Governments and local authorities should publish regular progress reports and success stories to demonstrate the positive impacts of conservation efforts. These educational resources will help build long-term community commitment to tree preservation.

Preserving our urban forests represents one of the most significant challenges in modern city planning. In order to be successful, we need commitment from stakeholders, backed by strong environmental policies and practical protection measures. As we continue to develop our cities, the strategies outlined here provide a foundation for ensuring that urban forests continue to thrive, and deliver benefits to current and future generations.
