In December 2022, SGPGA completed the cooperative agreement and submitted the August 31, 2022, Management Plan for the Juniper Drive Natural Area, which encompasses all of China Hill.
Final Recovery Plan for Phlox hirsuta (Yreka Phlox) F 8 Yreka Fish and Wildlife Office (530) 842-5763 Yreka phlox Phlox hirsuta 2 5.1 Determine whether Phlox hirsuta populations are stable, increasing, or declining over time Complete FY 2008 FY 2019 U.S. Fish and Wildlife Service California Department of Fish and Game, Universities or Colleges Research: Population Surveys Internal Technical Assistance, Internal Field Assistance, Internal Administrative A pilot study for a long-term population and threats monitoring program was initiated at 4 occurrences in the 2008 field season and continued in the 2009 field season. An eleventh year of the long-term population and threats monitoring program was completed in the 2018 field season and additional population monitoring at China Hill was conducted in 2019. The total number of plants at each population has not declined by more than 10% at any of the 4 occurences over the 12 years of the population monitoring study and all but the China Hill occurrence show higher numbers of plants on transects than there were at the initiation of the study. Therefore, across the species, the populations are stable.
