Washington County Greenspace Bird Surveys

Portland Metro West | Year-Round

Help us understand how bird communities are responding to habitat restoration efforts at important greenspaces in Washington County including at PCC Rock Creek, Cook Park and Fernhill Wetlands. Count and identify birds as you walk a trail.

The goals of this project are to help Clean Water Services and other partners understand how bird communities are responding to habitat restoration enhancement at key Washington County greenspaces and assess how effectively they provide ecological connectivity to the wider network of greenspaces in the Portland Metro region. This project aims to create increased awareness and appreciation of urban greenspaces that enhance livability for communities while also minimizing impacts to urban wildlife.

Important: Our emphasis is at Cook Park and PCC-Rock Creek so we encourage prioritizing eBird surveys at those sites. We recently completed a multi-year assessment of bird use at Fernhill Wetlands with the help of data collected by community scientists – thank you (see the findings below)!

Partners: Clean Water Services, Portland Community College – Rock Creek, eBird
