Initial Floristic Prospecting in the BLM Cache Creek Wilderness, Lake County, CA.

The Bureau of Land Management's Cache Creek Wilderness is a roadless natural area in Lake County with unexplored botanical resources. The Wilderness and the adjacent Bear Creek Ranch together form the BLM Cache Creek Natural Area. In 2010, with funding from the National Landscape Conservation System, preliminary surveys for special-status plants were conducted during eight visits to the Wilderness. We mapped eight California Rare Plant Rank list 1B and five California Rare Plant Rank list 4 plants in the Wilderness and encountered many rare plant communities and fascinating landscapes. Most of the special-status plants that we mapped were on serpentine-influenced substrates. A large serpentine barren with waterfalls and serpentine riparian vegetation is present near the southern border of the Wilderness, one of many areas in the Wilderness that need further exploration. Herbarium specimen vouchers from this study were incorporated into the herbarium at the UC Davis Center for Plant Diversity. The plant species recorded during this study were added to the existing plant list of the adjacent BLM Bear Creek Ranch to create a joint plant list for the Cache Creek Natural Area.
