Bark’s network of volunteer groundtruthers help us monitor every logging project and destructive action in Mt. Hood National Forest and surrounding public lands. The information gained from groundtruthing allows Bark to provide the public with all the information needed to understand, and engage in, decisions affecting public forest lands.

Photos and data collected in the field are uploaded to our online database, which also contains maps and documents of every project we are currently monitoring.

Groundtruthing is simple. Visit a proposed timber sale and document what the Forest Service or BLM is proposing. This information enables Bark, and you, to compare what the agency is planning on the ground versus what it states in the timber sale documents. Past groundtruthers have found discrepancies in agency information and documented rare plants and animals that have led to the cancellation of some or all of the proposed logging.

Getting started is easy. Bark hosts groundtruthing trainings throughout the year in our Rad·i·cle Program and as a stand-alone training. Check our events page to find upcoming trainings.  Trainings usually occur once during April and once during the summer.
