Portland, Oregon Tree Services

Our Portland tree service company strives to create a world where trees and humans live in harmony through the practices of arboriculture, restoration ecology and non-commercial forestry.

Treecology’s mission is to protect Oregon’s forest canopy, both urban and rural, by providing professional arborist services for new and established trees. Vast forests of incredible height once covered much of the Earth with species that evolved in the environments they were living in. We have removed these wise and ancient forests and replaced them with monocultures of genetically similar individuals (Douglas fir plantations for example). Portland, Oregon’s urban areas are filled with trees growing apart from the ecosystems in which they evolved, constricted by concrete and shaped, often harshly, to fit our parameters. Treecology’s tree maintenance, tree preservation and ecological restoration services mimic natural processes, replacing the diversity and missing components in the ecosystems, and guide rather than force trees to co-exist with us.

Treecology’s professional arborists are dedicated to providing the best possible tree service for our tree care clients, whether it be tree and shrub pruning, tree preservation, consulting, tree removal, tree risk assessment, cabling and bracing, tree house building or other arboricultural services.

Partners in Tree Care

Treecology has partnered with many proactive and progressive organizations to both care for both the trees and the environments they influence. These organizations look to Treecology not only for sound Arboricultural and Ecological advice, but for exceptional workmanship, professional service and the current knowledge about tree care and
restoration ecology.
