Regional Grazing Monitoring Plan
This project evaluates using grazing as a management tool for degraded grasslands and coastal sage scrub habitat. Pilot projects will be conducted to look at the efficacy of grazing as management tool and necessary monitoring methods. The project was designed to answer four primary questions (and their associated objectives): 1) How effective is grazing at reducing fire risk? 2) Can grazing effectively enhance disturbed native grassland and forb habitats 3) Can grazing enhance disturbed native coastal sage scrub habitat? 4) Can grazing reduce nonnative grass and forb cover in disturbed coastal sage scrub to increase native shrub cover and bare ground and improve habitat for MSP species such as Quino checkerspot butterfly (Euphydryas editha quino), California gnatcatcher (Polioptila californica), and black-tailed jackrabbit (Lepus californicus)? Initial study sites were established at Rancho Jamul Ecological Reserve and Hollenbeck Canyon Wildlife Area. This is a SANDAG-funded project.

Otay tarplant Deinandra conjugens
Goal: Maintain or enhance existing Otay tarplant occurrences to ensure multiple conserved occurrences with self sustaining populations to increase resilience to environmental and demographic stochasticity, maintain genetic diversity, and ensure persistence over the long term (>100 years) in native and non native grassland vegetation communities.
MGT-DEV-BMP DEICON-3
Management units: 3
In 2017 continue the collaboration with the South County Grasslands Project initiated in 2014 to develop BMPs for landscape-scale restoration of Otay tarplant habitat in MU3 that includes testing methods of seeding and invasive plant control so that nonnative plants and thatch are reduced to less than 20% relative cover and thatch to <5 cm tall and native plants to at least 25% relative cover. These percent cover criteria could be revised based on data collected from an acceptable reference site.

coastal sage scrub
Goal: Maintain, enhance and restore coastal sage scrub on Conserved Lands in the MSPA that supports or has the potential to support VF species (i.e., cliff spurge, Palmer's goldenbush, San Diego barrel cactus, snake cholla, Blaineville's horned lizard, California gnatcatcher, San Diego black-tailed jackrabbit) and to incidentally benefit a diverse array of other species (e.g., San Diego thornmint, Hermes copper, Quino checkerspot, coastal cactus wren) so that the vegetation community has high ecological integrity, and these species are resilient to environmental stochasticity, catastrophic disturbances and threats, such as very large wildfires, invasive plants and prolonged drought, and will be likely to persist over the long term (>100 years).

In 2020-2021, begin implementing and testing the plan for landscape-scale invasive plant control of coastal sage scrub and grassland ecosystems at 3 or more selected sites with extensive (at least 200 acres) coastal sage scrub and grasslands with large nonnative grass component, using livestock that are most suitable and feasible to manage for the grazing study, effective at controlling invasive nonnative annual grasses, and that are least likely to impact native plant and animal species. Test management methods for enhancing coastal sage scrub to reduce invasive plants and to increase native forb, grass and shrub cover and bare ground. Test management techniques for nonnnative grassland to improve habitat for MSP species such as Quino checkerspot, burrowing owl, golden eagle, grasshopper sparrow, black-tailed jackrabbit and American badger. Incorporate layered treatments of different control methods in the experimental design.

Beginning in 2019, prepare a plan to test the use of grazing, prescribed fire and other methods of landscape-scale control of invasive grasses and forbs in grassland and coastal sage scrub vegetation communities as BMPs to promote MSP species, native plants and animals, and natural ecosystem processes. The plan should determine the effects of different techniques on natural resources at 200 acre treatment areas at 3 different sites in the MSPA. Development of the study plan's experimental approach should include a review of the literature on the effects of grazing, prescribed fire, and other methods of invasive plant control on coastal sage scrub and grassland ecosystems to develop a conceptual model for management and monitoring. The plan should detail how to test different plant control methods over at least 3 years and should include the specific monitoring questions, objectives, and monitoring targets, a statistically valid experimental design with monitoring methods, sampling locations, and standardized protocols. The plan should include annual monitoring to determine the benefits and impacts of each method on natural resources and to track financial costs, logistics and sustainability of invasive plant control.
