South San Diego County Grassland Project

The purpose of the project was to to develop landscape-scale, collaborative strategies for managing target grassland species in the South County MSCP. Phase I involved grasslands assessments, target selection, and experimental design while Phase II was the experimental design implementation. Develop BMPs for restoring native grassland and forbland habitat for Otay tarplant and Quino checkerspot. The native grassland habitat restoration experiment compared the effectiveness of seeding full extent vs. Desimone strip seeding method, determined whether recent fall burn impacts success of two seeding approaches, and evaluated whether hand weed control and seeding methods are as effective as mechanized methods. The research goal for forblands was to assess the effectiveness of two mechanized site preparation techniques that limit soil disturbance while reducing weed cover in sites with good access and low native forb cover.The research goal for Quino checkerspot butterfly was to assess the effectiveness of two seeding techniques in establishing Plantago erecta and other QCB forb species on difficult to reach sites and sites with sensitive soil crusts. The research goals for Otay tarplant were to evaluate the effectiveness of establishing OTP populations using hand broadcast seeding or two-way drill seeding and to determine if calcareous soils are limiting the establishment of OTP populations.
