Come to the forest with us THIS SUNDAY🌲Join us on an excursion to Larch Mountain to learn how to groundtruth! We'll learn how to measure the diameter at breast height (DBH) of trees, look for fire signs, identify plants, measure slope and canopy cover, and more. The data we collect while groundtruthing helps us fight against destructive timber sales and protect forests.
No experience necessary, and carpool is available! Sign up here: https://bark-out.org/event/groundtruthing-201-field-training-2/

Want to groundtruth proposed timber sale areas with us this summer? Join us at Larch Mountain for our Groundtruthing 201 Field Training! No experience necessary. Carpool available!
What is groundtruthing? It's Bark's way of monitoring every timber sale proposed on Mt. Hood. We go out to proposed timber sale sites and document the forest conditions within the area, and then use that information to engage the National Environmental Policy Act (NEPA) to participate in the decision-making process for public forests. Since 1999, Bark and our dedicated volunteer groundtruthers have saved tens of thousands of acres from destructive logging projects that would have harmed Mt. Hood's forests and watersheds.
At this training you will get the opportunity to learn why we survey, what we survey for, and how we use the data to alter/stop timber projects and hold the Forest Service accountable. We will view examples of different kinds of forest stands we encounter during surveys and practice using tools for data gathering. By the end, you’ll be one step closer to becoming a groundtruthing pro!
