Assessment Notes
Taxonomic notes
Why suggested for a Global Red List Assessment?
Lecanora simeonensis is a rare species that is endemic coastal areas of southern California where it is threatened by multiple forces.
Geographic range
Lecanora simeonensis is narrowly endemic to coastal southern and central California in eastern North America.
Population and Trends
Demographic studies are needed to assess and monitor populations sizes. Populations are currently presumed to be stable, although extant populations may represent remnants of a once larger range in the region.
Population Trend: Stable
Habitat and Ecology
Lecanora simeonensis is restricted to old wood and lignum in coastal habitats.
Threats
Historical activities including large scale conversion of natural habitats, intensive grazing, and recreation have led to habitat degradation throughout the region where this species occurs. Current threats include further conversion of natural habitats, habitat shifts/alteration due to climate change, air pollution, road/utility construction and maintenance, recreation and increased frequency/intensity of wildfires that have.
Conservation Actions
Conservation actions that can be taken including educating and training land managers and local botanists to identify the species so we can monitor its health as well as contracting experts to conduct detailed monitoring at various time intervals (every 5 to 10 years), federally listing the species as endangered in the United States. Further conservation of lands where existing populations occur, and intensive searches of inaccessible coastal areas, are also needed.
Research needed
Further research that will aid in the conservation of this species includes intensive searches for additional extant populations, population assessments and monitoring, population genetics studies, and ecological studies that incorporate threats to the species. Additionally, a species recovery plan needs to be written.
