Goal: Protect, enhance, and restore least Bell's vireo occupied and historically occupied habitat to create resilient, self-sustaining populations that provide for persistence over the long-term (>100 years).
Management units: 1, 6, 8
In 2017-2019, conduct surveys for least Bell's vireo and habitat assessment to compare population status and recovery in the MSPA before, during, and after SHB/Fusarium complex in infested habitat over time at the Tijuana River Valley and other sites, if funding available, such as Camp Pendelton and San Luis Rey River. Prepare site-specific management recommendations based on survey results and habitat assessments.

In 2020, if least Bell's vireo survey results indicate management is needed to reduce impacts from SHB/Fusarium infestation, then develop a management plan that incorporate SHB/Fusarium monitoring and management and prioriotize management recommendations.
