A total of 39 plans were surveyed to completion; 6 plans were initiated in 2015 and completed in 2016; and 7 plans were initiated in 2016 and will be completed in 2017. The 2016 floristic survey season commenced on February 2nd and terminated on September 9th with an estimated 152 field days. A total of 120 new California Rare Plant Rank (CRPR) 1-2 BotID#s were generated representing 8 taxa. It is worth noting that 91 of 120 the new CRPR 1-2 BotID#s are previously unrecorded populations of Monotropa uniflora. A total of 133 new CRPR 3-4 BotID#s representing 12 taxa were generated as part of a continued commitment to collecting spatial and habitat data for uncommon species. One California Rare species, Bensoniella oregona, was identified on the Wiggins North THP; no other State or Federally listed Rare, Threatened or Endangered species were identified during the 2016 survey effort. Within the Coastal Lagoons and Little River Botanical Management Area (BMA), 9 harvest plans were reviewed and 4 received surveys in unique habitats. With the exception of Lycopodium clavatum, no rare or uncommon taxa were identified in the BMA. A summary data set for all occurrences was submitted to the California Natural Diversity Database (CNDDB) on February 1st, 2017; this package included 253 field survey forms for all CRPR taxa discovered in 2016; and 14 follow-up forms for three taxa and the corresponding location data in ESRI File Based Geodatabase (FBGDB) format. Monitoring for Montia howellii in the Salmon Creek Tract continued for a sixth consecutive year. Surveys were conducted by a 4-person technical team from March 10th through March 25th for a total of ten field days. Results of the occupancy data show a sharp increase from the 2015 numbers; with the data showing moderate variability and an overall trend of decline and recovery from year to year. No major changes to the program are proposed at this time. As we prepare for the 2017 season, some minor modifications may be made to the specific data collected and the rubric for habitat typing. For example, the California Manual of Vegetation will be the guiding habitat typing reference and it is our goal to be more concise about habitat descriptions so that it may contribute to a larger data set. While minor modifications may be made to improve efficiency and clarity, no deviations from the Sensitive Plant Conservation Plan nor the Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFW 2009) are proposed.

Lack of full identification was typically due to a lack of flowering individuals; this has particularly been a problem with Piperia and Erythronium. Plants are often detected in the spring by their leaves which senesce by the
