The Private Urban Forest

Tomorrow Foundation Tree Count

About this project

In the summer of 2021 we conducted a pilot project in the Queen Alexandra Neighbourhood where we gathered information about the trees on private property.

The private urban forest refers to the “trees that reside on private property and are therefore not maintained by the City of Edmonton.” The oldest private trees in the City typically sit on properties of the oldest homes because they are often planted at the time a property is developed. Due to their larger size, older more mature trees are also the trees that provide the most benefits for climate and other ecosystem services. The larger they are, the more they can do to clean our air, absorb stormwater, reduce GHG emissions from our atmosphere, and provide potential energy savings to homes. Infill housing development sites are also a place where the City’s tree inventory is actively changing; older trees are often removed while new trees are being planted. As infill occurs to accommodate population growth and densification plans, mature trees are often lost due to the land being cleared for new development. Therefore, infill developers are key decision-makers in preserving trees in the City as well as deciding what new trees will be planted. It is important to engage them to better understand the current and future state of the private urban forest.

This project is linked to an increasingly important topic of how Edmonton can continue to grow with the desired densification through infill while also meeting its climate resilience goals. For example, the Edmonton City Plan  is a roadmap for how it will manage its long-term growth while doubling its size and continuing to be a healthy and climate resilient City. One part of the Plan discusses the Greener as We Grow initiative which is an initiative to plant 2 million trees in the City and to help achieve a community-wide carbon budget target and ultimately support a net zero GHG emissions per person goal. Another part of the Plan is to help the City meet its population growth and increased housing needs through densification by supporting 50% of net new units to be infill. Both of these initiatives in the Plan are intended to bring about more sustainable and healthy living in the City of Edmonton. Our hope is that this project sheds light on how these two initiatives interact and how thoughtful urban planning could lead to more trees being preserved and planted as well as more infill housing development to support a more sustainable, walkable-bikeable, 15-minute City. Thus, it is important to get a better inventory of trees on private property in order to better understand these interactions in Edmonton and how it is changing.

Project Description

Have you ever pondered how the trees on your property benefit you?

Or what kind of trees are growing on your property?

Have you ever considered how much of our urban forest resides on private property?

We at Tomorrow Foundation are asking these questions, and more!

This summer we are piloting a project in the Queen Alexandra Neighbourhood where we want to gather information about the trees in your yard! This project has the potential to grow into other neighbourhoods in the coming years.

Why is it important to gather this information?

A growing city impacts the trees of our public land (public urban forest) and private land (private urban forest.) By gathering a baseline of information now, we can better understand how these changes will affect us in the future!

The City of Edmonton has a goal to plant 2 million trees to help combat climate change. Getting information about private trees will allow us to advise the city as to the best places to plant them!

Much of our urban forest is on private property. In order to create accurate assessments to meet Edmontons climate goals we need to know what we have!

We need you!

Here are ways you can help make our project a success!

  1. If you are in the Queen Alexandra Neighbourhood please give us permission to enter your property so we can measure your trees.
  2. You can measure your own trees and send us the information.
  3. Join our volunteer team and help us measure!

Contact us at

What information are we gathering and why?

In order to get accurate results we are collecting this information.

  1. Tree species – Each species uniquely interacts with its environment.
  2. Circumference of the trunk and Height of tree – A sign of age and overall vigour.
  3. Dead branches – A sign of the tree’s health.
  4. Exposure to sunlight – A sign of the growing conditions of the tree.
  5. Distance to the house – An indicator of potential home energy savings.

Benefits to you

  1. You can get a personalized report about what services the trees provide for you (e.g. energy savings, reduction of air pollution)
  2. This data will be added to a larger report about the Queen Alexandra neighbourhood
  3. You could gain a free sapling!

Can I opt out?

Of course! This is volunteer only.
