Invasive plants

Goal: The overarching goals for addressing invasive plant species in the MSPA are to: (1) Protect Conserved Lands from new or expanding invasive plant species; (2) Detect new invasive species and new invasions early on and control them before the plants have a chance to establish; (3) Address invasive species using the response appropriate for the level of invasiveness (level 1 through 5) as defined in the Invasive Plant Strategic Plan (IPSP)

Code Obj. code Statement
DICORC-1 MON-IMP-IMG From 2017 to 2021, inspect Orcutt's bird's-beak occurrences annually on Conserved Lands (see occurrence table) using the regional rare plant IMG monitoring protocol to record abundance and collect habitat and threats covariate data to determine management needs.
DICORC-3 MON-RES-GEN In 2017, complete the study begun in 2016 to characterize the population genetic structure, gene flow, and genetic diversity for Orcutt's bird's-beak occurrences (see occurrence table). The study will determine if there is evidence of mixed ploidy levels within or among occurrences; evaluate vulnerability of occurrences to genetic drift and loss of genetic diversity; assess the level of gene flow among occurrences; identify if there are signatures of genetic bottlenecks or low genetic diversity in occurrences that have undergone recent reductions; and look for evidence of local population adaptation. Based on the results of the genetic analyses, management recommendations will include whether common garden and reciprocal transplantations are necessary before proceeding with population enhancement or restoration and will provide specific recommendations for collecting, bulking and distributing seed to enhance existing occurrences or establish new occurrences.
DICORC-5 MGT-IMP-IEX From 2017 to 2019, enhance Orcutt's bird's-beak at the Cal Terraces/Dennery Canyon occurrence (see occurrence table). Invasive plant control should be conducted using BMPs so that invasive plants are reduced to less than or equal to 20% absolute cover within the occurrence’s occupied extent and adjacent suitable habitat.
DICORC-7 MGT-IMP-SBPL From 2017-2019, collect Orcutt's bird's-beak seed for conservation banking and bulk seed for enhancing and expanding the Cal Terraces/Dennery Canyon occurrence (see occurrence table). In 2021, begin implementing high priority actions for Orcutt's bird's-beak in the MSP Seed Collection, Banking and Bulking Plan to collect and store seeds at a permanent seed bank and to provide propagules as needed for management oriented research, existing population enhancement and establishment of new occurrences.
DICORC-8 MGT-PRP-MGTPL In 2020, begin preparing an Orcutt's bird's-beak section in the MSP Rare Plant Management Plan that prioritizes management actions to maintain large occurrences and expand at least 3 small occurrences on Conserved Lands (see occurrence table) based upon an assessment of data on occurrence status, habitat and threats. Prepare management recommendations for re-establishment of historic occurrences or establishment of new occurrences if determined to be necessary for gene flow and for long term persistence. Minimum criteria for enhancement are to reduce invasive annual nonnative plants and thatch to less than 20% absolute cover within the occurrence
