PROTECTION STATUS: Endangered
YEAR PLACED ON LIST: 1998
CRITICAL HABITAT: Approximately 73 acres in California’s San Diego County designated in 2006
RECOVERY PLAN: None
RANGE: Concentrated in the Miramar area of San Diego County. Another closely related species recently taxonomically split from the willowy monardella is also rare in the United States, but extends south into Baja California, Mexico. This taxonomic split effectively reduced the numbers of the true willowy monardella to even fewer populations.
THREATS: Urban development, sand and gravel mining, off-road vehicle activity, trampling, trash dumping, erosion, fire, road construction, hydrological alterations, and invasion of nonnative species
POPULATION TREND: This plant is severely declining; currently, there are 10 known occurrences of willowy monardella in San Diego County. To date, occurrences of the plant have been extirpated by transportation projects and industrial development.
