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 2017, prepare a long-term monitoring plan for the mosaic of chaparral, coastal sage scrub and grassland vegetation communities that focuses on tracking community composition, structure and ecological integrity over time in relation to climate (i.e., drought) and disturbance from fire. The monitoring plan should include a conceptual model, specific monitoring questions, the sampling frame within the MSPA, monitoring methods, a statistically valid sampling design, permanent sampling locations, timeline, and standardized protocols. Use the landscape-scale ecological integrity classification map to develop a sampling frame and the sampling design with permanent sampling plots spanning north to south and east to west environmental gradients across the MSPA. Evaluate how the vegetation integrity classes characterize other aspects of the ecosystem by integrating other types of monitoring into the long-term sampling plots, such as abiotic element monitoring (e.g., automated weather stations and soil sensors, GIS-data layers), ecological integrity monitoring (e.g., plant and animal communities, ecological processes), MSP VF species monitoring, and threats monitoring (e.g., fire, climate change, invasive plants). A draft monitoring plan should be prepared in 2017, tested in the field with a pilot study in 2018, and finalized by 2019.

In 2017, develop a landscape-scale map classifying ecological integrity of shrublands across the MSPA based upon shrub cover and density and invasive nonnative annual grasses using remote imagery (e.g., satellite and high resolution aerial imagery, LIDAR) and vegetation data collected during 2015-2016 California gnatcatcher regional and postfire monitoring. Verify and revise the mapping as needed using field data collected in 2018-2020 as part of the Chaparral, Coastal Sage Scrub and Grassland Monitoring Program and from related VF species monitoring (e.g., California gnatcatcher regional and postfire monitoring). Revise the integrity classification map as needed to respond to changes in vegetation based upon wildfires, drought or other large-scale disturbances.

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.

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.
