All but three of the 23 special status plant species that occur, or once <br />occurred, in the vicinity of the project site were either determined to be absent or unlikely to <br />occur on the site during the initial 2014 reconnaissance-level field survey. Reasons for such <br />determination included the lack of suitable habitat for the species, the species has not been <br />observed in the project region for many decades, and/or because habitat was considered <br />marginal on the site for the species. The three rare plant species that were determined to have <br />the potential to occur on the site after the 2014 survey included big-scale balsamroot (perennial <br />herb; blooms March-June), Congdon’s tarplant (annual herb; blooms May-November) and Diablo <br />helianthella (perennial herb; blooms March-June) (Table 2). Therefore, LOA ecologists Pamela <br />Peterson and Davinna Ohlson conducted focused surveys for all three potentially occurring rare <br />plant species on September 15, 2014. The survey was timed to coincide with the blooming season <br />for Congdon’s tarplant, which is a late season blooming annual herb. Although the survey was <br />conducted outside of the blooming season for both Diablo helianthella and big-scale balsamroot, <br />the latter are perennial herbs, and these plants would have still been observable/identifiable <br />throughout the year if they were present. The survey was conducted both within the proposed <br />development grading footprint and proposed conservation lands. Big-scale balsamroot and <br />aA -----------
