Poison hemlock requires careful handling and correct identification. This article from OSU Extension is geared toward pasture lands, but may be helpful for you. Do you have numerous plants? Share photos if you want plant identification assistance.

Contact your Clackamas County Soil and Water Conservation District to see if you qualify for assistance with your property.

Look alike plants are common, and most should still be handled carefully. This page from Maine has useful photos and descriptions of toxic properties. The purple blotches are distinctive for poison hemlock.

UC IPM page also details manual removal steps as well as chemical.
