Rank Reasons
Coville's Lipfern occurs in western North America, in California, southern Oregon, southern Nevada, southwestern Utah, Arizona, in the Uniterd States and in Baja California, Baja California Sur, Chihuahua, and Coahuila states in Mexico. There are an estimated 210 occurrences, and these include many on National Forests, National Parks, and BLM Wilderness Areas. Threats include recreation impacts from rock climbing, and impacts from extreme or long-term drought, such as may be exacerbated with climate change.
Range Extent Comments
Coville's Lipfern occurs in western North America, in California, southern Oregon, southern Nevada, southwestern Utah, Arizona, in the Uniterd States and in Baja California, Baja California Sur, Chihuahua, and Coahuila states in Mexico. The range extent was estimated to be 633,000 square kilometers, using herbarium specimens and photo-based observations documented between 1992 and 2023 (CCH2 Portal 2023, Flora of North America Editorial Committee 1993, GBIF 2023, iNaturalist 2023, Oregon State University 2023).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1992 and 2023, it is estimated that there are between 81 and 300 occurrences rangewide (CCH2 Portal 2023, GBIF 2023, iNaturalist 2023).
Threat Impact Comments
Threats include recreation impacts from rock climbing, and impacts from extreme or long-term drought, such as may be exacerbated with climate change.
