Notes from the Field

It is nearing the end of my summer internship with Rare Care, stationed at Mount Rainier National Park, and I am excited to share what we found! The internship opportunity sprung from a collaboration between Rare Care and the National Park Service to confirm and improve the accuracy of rare plant records within Mount Rainier National Park’s boundaries. For the Park Service, this work will provide vital spatial information about rare plants to inform management decisions.
