Rare Plants in progress

Rare Plant Inspect and Manage Monitoring 2014-2026

From 2014-2026, a Management and Monitoring Strategic Plan (MSP Roadmap) monitoring objective for 30 rare plant species is to inspect occurrences to determine management needs. The inspect and manage (IMG) objective is implemented to document the status of rare plant occurrences and assess habitats and threats to develop specific management recommendations. IMG monitoring is implemented by a combination of land managers and contracted biologists in coordination with the SDMMP. Available rare plant data is posted below. New annual updates are typically posted in March. Based upon an evaluation of these data, a 2014-2026 monitoring schedule has been developed for the 30 rare plant species (attached below). Coordinating data collection across the region allows analyses of species and population trends over time and provides a better understanding of the association between habitat and threat covariates and population dynamics.

Coast wallflower Erysimum ammophilum

Goal: Maintain or enhance existing coast wallflower occurrences and establish new occurrences, as needed, to ensure multiple conserved occurrences with self sustaining populations to increase resilience to environmental and demographic stochasticity, maintain genetic diversity, and improve chances of persistence over the long term (>100 years) in chaparral, coastal bluff, coastal dune and coastal sage scrub vegetation communities.

Management units: 6, 7

Beginning in 2017, inspect occurrences of coast wallflower on Conserved Lands (see occurrence table) using the regional IMG monitoring protocol to record status and to collect habitat and threats covariate data to determine management needs. After 2017, repeat monitoring every 2 years.

ERYAMM-2 MGT-IMP-IMG Beginning in 2017, conduct routine management actions as identified through the IMG monitoring at coastal wallflower 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.
ERYAMM-4 MGT-PRP-SBPL In 2021, begin preparing a section for coast wallflower in the MSP Seed Collection, Banking and Bulking Plan to preserve genetic diversity and rescue occurrences in case of catastrophic disturbance. The plan should incorporate best science and management practices (e.g., Wall 2009; KEW 2016) to provide guidelines for collecting and storing seeds over the long term at a permanent, established conservation seed bank (e.g., Institute for Conservation Research Native Plant Seed Bank, Rancho Santa Ana Botanic Garden Seed Conservation Program) and for providing a source of seeds for management purposes. The plan should include recommendations for: collecting and storing seeds to provide source material with consideration of potential genetic consequences; for management oriented research; seed bulking; and out-planting to augment extant occurrences or establish new occurrences.
ERYAMM-5 MGT-PRP-MGTPL In 2021, begin preparing a section for coast wallflower in the MSP Rare Plant Management Plan that prioritizes management actions to maintain and expand conserved occurrences based upon an assessment of data on occurrence status, habitat and threats. Prioritize management recommendations for re-establishment of historic occurrences or establishment of new occurrences in suitable habitat, as needed, to achieve at least 4 occurrences with self-sustaining populations on Conserved Lands (see occurrence table). Minimum criteria for enhancement are to reduce invasive annual nonnative plants and thatch to less than 20% absolute cover within the occurrence

Heart-leaved pitcher sage Lepechinia cardiophylla

Goal: Maintain or enhance existing heart-leaved pitcher sage occurrences and establish new occurrences, as needed, 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 and oak woodland vegetation communities.

If extant occurrences of heart-leaved pitcher sage are discovered on Conserved Lands in 2017-2021, inspect the occurrences and repeat monitoring every 2 years. Use a regional monitoring protocol to record population abundance and collect habitat and threats covariate data to determine management needs.
