Goal: Maintain or enhance existing Otay tarplant 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 native and non native grassland vegetation communities.
Management units: 3
In 2017, continue field research into soils and habitat relationships and development of habitat suitability and climate change models for Otay tarplant 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.
| Action | Statement | Action status | Projects |
|---|---|---|---|
| RES-1 | Test soils at potential expansion sites and compare to occupied reference sites to determine site suitability based on soils. | In progress | Enhancing the Resilience of Edaphic Endemic Plants |
| RES-2 | Prepare habitat suitability models under current environmental conditions and for different scenarios of climate change to delineate potential future habitat. | In progress | Enhancing the Resilience of Edaphic Endemic Plants |
| RES-3 | Collect covariate data on vegetation composition and cover (alliance and association-level mapping), soils, invasive plants and other threats for selected populations. | In progress | Enhancing the Resilience of Edaphic Endemic Plants |
| RES-4 | Prioritize locations for conservation, management, and future surveys based on predicted distributions and environmental correlates. | In progress | Enhancing the Resilience of Edaphic Endemic Plants |
| RES-5 | Submit project metadata, monitoring data, habitat models, analyses, and report to MSP web portal. | In progress | Enhancing the Resilience of Edaphic Endemic Plants |
