Goal: Maintain or enhance existing Thread-leaved brodiaea 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 grassland and vernal pool vegetation communities.
Management units: 6, 7, 8
Beginning in 2017, inspect conserved populations of thread-leaved brodiaea in (see occurrence table) using the regional rare plant IMG monitoring protocol to record abundance and collect covariate habitat and threats data to determine management needs. After 2017, repeat monitoring every 2 years.

Beginning in 2017, conduct routine management actions identified through the IMG monitoring at thread-leaved brodiaea occurrences on Conserved Lands (see occurrence table). Depending on the type and level of threat, management should only be conducted as needed, not necessarily every year, and using BMPs with precautions to do no harm.

In 2017, continue field research into soils and habitat relationships and development of habitat suitability and climate change models for thread-leaved brodiaea and other edaphic endemic plants to better understand habitat requirements and to identify and prioritize geographic areas important for connectivity, restoration, and range shifts due to climate change and other threats.
