Our Team

Our Team of Plant Biologists and Experts

Certified arborists providing professional vegetation management.

Northwest Weed Management has merged with Peninsula Urban Forestry to offer a robust suite of vegetation management and other land management services. Peninsula Urban Forestry is a family-owned business based out of Sequim, WA. Our team provides the same professional vegetation management and weed spraying services Northwest Weed Management customers are accustomed to.

Peninsula Urban Forestry is focused on connecting our natural environment with our built communities. We provide science based, objective solutions to plant management and ecological restoration. Our Certified Arborists are not in the business of removing trees, rather we objectively evaluate their health, safety and longevity. Our wetland scientists provide accessible planning and evaluation of wetland systems within our communities. Our team of plant experts have successfully restored habitats and ecologies of wetlands, streams, shorelines and promoted priority habitat in Western Washington. Let us help you better manage your land and plants.

In addition to weed control services, Peninsula Urban Forestry offers plant health care & tree inspection services, habitat restoration, consulting arborist services, forestry planning, and wetland delineations. We have State licensed pesticide applicators, arborists, foresters and biologists on staff. We are looking forward to working with you on your future land management needs.
