Mexican flannelbush Fremontodendron mexicanum

Goal: Maintain or enhance existing Mexican flannelbush 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.

MGT-IMP-IMG FREMEX-2

Management units: 3

Beginning in 2017, continue routine management actions identified through the IMG monitoring that began in 2014 at Mexican flannelbush 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.

FREMEX-1 MON-IMP-IMG In 2017, inspect Mexican flannelbush occurrences on Conserved Lands (see occurrence table) using the regional IMG monitoring protocol to estimate abundance and collect covariate data on tamarisk and other types of threats, determine management needs. After 2017, repeat monitoring every 3 years, unless an occurrence is small (<100 individuals) or faces a high degree of threat, in which case monitor annually.
