Forestry Inventory & Analysis – Priest Point Park

While employed with the City of Olympia, John Bornsworth conducted a forest analysis with a habitat biologist. The project consisted of timber mapping, invasive species mapping, and native vegetation mapping. Together we identified and mapped associations between colonies of invasive English ivy and a reduced level of native tree recruitment. This data was eventually used […]

Bo Baggins Daycare, Maple Assessment

Bo Baggins Tree evaluation and analysis by professional arborists. The Bo Baggins daycare, Sitkum Tree Service and the City of Port Angeles contacted us about a potentially high-risk tree in uptown Port Angeles.

Smith Island/Union Slough Noxious Weed Management

Peninsula Environmental Group planned and executed the removal of Class A noxious weeds Purple Loosetrife, Yellow Iris and Knotweed. The project was part of the Smith Island/Union Slough Restoration Project. The site, a restored estuary, was surveyed and weeds were manually removed to reduce the invasive spread and encourage native growth. Working with the tides […]

Lyre Creek Conifer Release

The North Olympic Land Trust contracted with us to provide forest stand maintenance services at their Lyre Creek Restoration site. We performed preliminary conifer release, stand restoration, and stand thinning services to a 30-acre parcel within Lyre. NOLT will be returning with volunteers to complete a section of red alder thinning required for their Natural […]

Terra Haven Tiny Home Development

PEG provides Tree Conservation & Protection Plans for different engineering firms, landscape architects, builders and developers across the Puget Sound.

We assisted site planning by identifying the bald eagle nesting zone, determining the required buffers and […]

Iron Springs Owners Association

Peninsula Environmental Group is an on-call community forester and arborist for Iron Springs Owners Association, a coastal community nestled between enormous ancient spruce trees and native coastal shrubs. The association receives arborist reports from a number of local independent arborists. When multiple arborist reports contested or disagreed with each other we offered fact-finding and objective […]

U.S. Coast Guard, Noxious Weed Control

Many facilities require vegetation free zones to ensure safe and easy accessibility for use and maintenance. This is especially true for critical infrastructure, like the U.S. Coast Guard communications facility that aids in at sea emergency response situations.  We maintain a weed free area and buffer at one such facility in Discovery Bay. Weeds onsite […]

Clallam Bay Corrections Center – Institutional Vegetation Control

Location: Experts: Clallam Bay Corrections Center requires a facility wide, 30-foot perimeter of bare-ground around their facility. We visit the facility two or three times per year.  Year-round vegetation control is achieved with a variety of pre-emergent and post-emergent chemicals.  Our treatments follow a strenuous integrated plant management plan which designed to reduce  harm to […]

Cottage Development Tree Protection Plan

Our Certified Arborists conducted a tree inventory and developed a Tree Conservation Plan and supplemental Tree Protection Plan for a unique forested, cottage development within the City of Port Townsend. A ½ acre forested property was planned for development of 6-7 single-family tiny homes, or cottages as identified in Port Townsend Municipal Code. In collaboration […]

Private Marine Shoreline & Steep Slope Erosion Control/Restoration

This project was designed to remove invasive plant species and install native vegetation to reduce rainwater disturbance, provide slope stabilization, and enhance wildlife habitat.
