Article abstract: Vernadero Group Inc. was contracted by Naval Facilities Engineering Systems Command Southwest on behalf of Marine Corps Air Station (MCAS) Miramar to conduct a Stationwide census for willowy monardella (Monardella viminea) and to monitor the species within long-term monitoring plots at MCAS Miramar in San Diego, California. We conducted willowy monardella surveys in 2023 following all census and monitoring methods described by the 2013 Willowy Monardella (Monardella viminea) Field Protocol Manual to ensure consistency with past and future willowy monardella surveys at MCAS Miramar. We surveyed and mapped all willowy monardella on MCAS Miramar, identifying adults, mature plants, juveniles, and seedlings. We used a standardized method to define and delineate clumps of willowy monardella during the census. We visited established monitoring plots and used standardized methods for measuring willowy monardella growth rates, determining clump health, and evaluating willowy monardella population expansion or contraction. We conducted census and monitoring activities at MCAS Miramar from 30 June 2023 through 12 August 2023.
