Gander's ragwort Packera ganderi

Goal: Maintain or enhance existing Gander's ragwort 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 chaparral vegetation communities.

Management units: 3, 4

Beginning in 2017, conduct routine management actions identified through the IMG monitoring in 2016 and subsequent years at Gander's ragwort occurrences on Conserved Lands (see occurrence table). Depending on the type and level of threat, management should be conducted as needed, not necessarily every year, and using BMPs with precautions to do no harm.
