Study the Scientist: A Botanist

The video discusses the diverse habitats in Yosemite National Park, highlighting the elevation range from 2,000 to over 13,000 feet. It addresses the impact of the invasive yellow starthistle on native flora and the park's efforts to manage it. The lichen inventory project, started in 2007, aims to document lichen species in the park, which serve as indicators of air quality and climate change. Lichens are explored as passive samplers of environmental conditions, with a focus on their diversity across different terrains. The video concludes with the excitement and complexity of studying nature in Yosemite.
