Blainville's horned lizard Phrynosoma blainvillii

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, willowy monardella, 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).

MON-RES-GEN PHABLA-1

Management units: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

In 2017 continue a next-generation DNA sequencing study to characterize the phylogeographic and population genetic structure Blainville's horne lizard in southern California, including Conserved Lands throughout the MSPA. This species is a target for regional-scale connectivity within and between core areas of the MSPA and will provide information important to identify areas that may require management to improve connectivity for small vertebrates.

MON-PRP-MONPL PHABLA-2

Management units: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

In 2018, develop a long-term Blainville's Horned Lizard Monitoring Plan to track their distribution and status, habitat associations and level of threats in chaparral, coastal sage scrub and grassland vegetation communities across Conserved Lands in the MSPA. The plan should integrate with the Chaparral, Coastal Sage Scrub and Grassland Vegetation Monitoring Plan to include sampling at long-term vegetation monitoring plots. The monitoring plan should build upon previous surveys, habitat assessments and modeling to develop specific questions, monitoring methods, a statistically valid sampling design, sampling locations, and standardized protocols for determining the status and abundance of the lizard and for assessing habitat and threats at each sampling site to determine vegetation management needs. The plan should include guidelines for data analysis and preparation of a report with monitoring results and vegetation management recommendations.
