Restoration Ecology

Tree trunk

Planting a tree is an act done for
the benefit of future generations.

At Treecology, we not only help to take care of the urban forest, we plant trees and forests for tomorrow. By working to restore the “natural” areas that surround us, restoration ecologists around the world are attempting to protect the services that our planet supplies for all living creatures – clean air and water, protection from ultraviolet radiation, sustainable food sources, a hospitable climate, etc. While we cannot save the world by ourselves, the arborists at Treecology are dedicated to doing our part in the Portland metropolitan area to ensure that future generations will be able to access these services, listen to frogs and birds, or just take a walk in the woods.

What is Restoration Ecology?

Restoration ecology is the science and art of recreating or emulating a current or former ecosystem for the benefit of conserving biodiversity. Enhanced biodiversity will lead to a more rigorous ecosystem, capable of withstanding higher levels of disturbance. A more rigorous ecosystem will be able to weather the future challenges of global climate change, human population expansion, exotic species invasion and the global spread of insects and diseases.

Much of the restoration work that takes place in Portland, Oregon and the Pacific Northwest is centered on its streams and rivers. These natural features function as wildlife corridors, allowing connectivity between larger areas of native habitat. The better the corridor, the better the function. By connecting these larger habitat areas we can help nature replenish its abundance in areas where it is lacking and distribute any overabundance.

Treecology offers assessment, design and implementation services for your restoration projects, large or small.

A journey of a thousand miles begins with one step. Whether we are providing technical assistance to the landowner, organizing the efforts of a group of volunteers or are up to our wazoos in the project, the experienced restoration ecologists at Treecology are happy to provide the level of help required to ensure a successful outcome. A robust installation will give the plants the competitive edge that they will require to outcompete non-native and invasive species, make sure that the in-stream structure that was created will stay a functioning part of the habitat, and ensure that the project is a beautiful example of humans who care giving Nature a hand.


Every successful project requires forethought and planning. This starts out with an assessment of the characteristics of the restoration site and of the goals of the property owner. A thorough understanding of where we are and where we are going will enable us to choose the correct path on which to travel.


Once the path is identified, a plan will provide us with a map of the best way to get from here to there. Plans can be as simple as planting willows on a floodplain to complicated soil bioengineering of new stream banks.


The staff at Treecology is well versed at putting the shovel in the ground. We have the experience and expertise to successfully implement your restoration project, from the initial blackberry battle to the final shovel of mulch on the plants. Our philosophy is that a robust installation of healthy plants is the best way to do a project. This will minimize the maintenance and replanting required, and will speed the site to a faster recovery.

Maintenance and Monitoring

Maintenance, however onerous, is one of the most crucial steps to a successful project. Many times, it is the sole cause for the failure of a project, which, after all that hard work and sweat during the previous phases, is an intolerable shame. Treecology can take the maintenance of your site off of your hands so that you can concentrate on other things, like your next project.

While we’re out there, we are constantly assessing the success of the project through monitoring and analyzing ways to adapt our management of the site. This adaptive management can maximize the success of the project while minimizing costs.
