Rarest Plants II Project Final Report
The purpose of the EMP grant is to improve the conservation status of three high-priority MSP plants: Orcutt's spineflower (SL); short-leaved dudleya (SL), and Orcutt's brodiaea (SO). The goals of the EMP grant are to significantly increase available seed and to restore, supplement, and protectively manage populations of three high-priority MSP SL and SO plant species, and to monitor results. Objectives under the EMP grant include: Seed bulking for all three species; control of invasive weeds for all three species; establishment of one new Orcutt's spineflower occurrence; supplementation of population numbers and stewardship management to maintain approximately sixteen existing occurrences of Orcutt's spineflower and one existing occurrence each of short-leaved dudleya and Orcutt's brodiaea; and renewing permits for Project work.
