Over the summer, my fellow intern, Maya Kahn-Abrams, and I monitored twelve species of alpine plants in Olympic and Mount Rainier National Parks. These plants were chosen from a list developed by botanists from each park to describe current status and collect long-term data to develop strategies for adaption to climate change. These species are generally tracked by the Washington Natural Heritage Program, while a majority of them are endemic to Washington State.
