University Researchers Map Out Vegetation In The Klamath Mountains

University Researchers Map Out Vegetation In The Klamath Mountains
Cal Poly Humboldt students and faculty across various disciplines are embarking on an ambitious project to map out vegetation in the Klamath Mountains. This data will have many applications, including understanding how vegetation regenerates after fires, and how plant communities are being affected by a drying and warming climate. In the long term, this project will advance regional understanding of climate change. “The Klamath Mountains are home to more than 3,500 vascular plant taxa, making it one of the most botanically diverse places in North America,” says Forestry Professor Lucy Kerhoulas (‘06, Botany, ‘08, MS Biological Sciences). Kerhoulas co-leads the study alongside other University faculty including Geography, Environment & Spatial Analysis Chair Rosemary Sherriff and Biological Sciences Chair Erik Jules.
The project aims to document and map the botanical diversity. The maps produced from these data will be the most comprehensive maps of plants in the Klamath Mountains, Jules says. The Klamath Mountains range is vast, spanning 19,000 square miles from Northern California to Southern Oregon. This project is focused in California only; it will conduct 1,600 vegetation surveys—each at a different location—and collect hundreds of specimens for the next three years. Surveying began this summer, and researchers—who include both graduate and undergraduate students—are on track to complete 500 surveys by the end of this year.
As part of these surveys, researchers will visit sites throughout the Klamath, documenting all the plants they encounter with a focus on vascular plants. They will then create a species list of all trees, shrubs, grasses, and forbs (herbaceous plants that aren’t grasses). Much of the plant samples they collect will be donated to the University’s Vascular Plant Herbarium—one of the largest in the California State University system with more than 105,000 specimens. The project is funded by the California Department of Fish and Wildlife. It is conducted in partnership with the California Native Plant Society, and the Bigfoot Trail Alliance.
