Dehesa Nolina Conservation and Management Strategy


Project description

The Conservation Biology Institute developed a science-based Conservation Vision and Management Strategy for Dehesa nolina in San Diego County. The Conservation Vision assessed the distribution, status, and threats of populations on conserved lands through data and literature reviews, site visits, and interviews with land managers. Products included spatial data layers, an updated matrix of threats and stressors, management recommendations, and prioritized populations for management. The Management Strategy focused on preserve-level management, using the existing Dehesa nolina population on the South Crest Preserve to test/refine management techniques, including species augmentation (seed collection, contract growing of plants, out-planting) and erosion control. These actions also benefitted Dudleya variegata (variegated dudleya) and sensitive native grassland habitat. These management actions complemented other Transnet-funded management on South Crest; techniques refined in this project are applicable to other conserved populations in the region.

Project protocol

Name: Management Strategic Plan (MSP) 2015 Monitoring Protocol for Rare Plant Occurrences on Conserved Lan

Description: Prepared by San Diego Management and Monitoring Program (SDMMP) 3-11-14 & revised 2-19-15. A Management Strategic Plan (MSP) was developed for western San Diego County to provide a biological-based foundation to support decision making and funding priorities for managing species and vegetation communities on Conserved Lands (San Diego Management and Monitoring Program 2013). There is a gap in our knowledge of the current status of many rare plant populations in the MSP area (MSPA) and an even greater deficit in our knowledge of the specific threats faced by each occurrence. In 2015, a top priority of the MSP is to obtain rare plant status and threat data across the MSPA in order to identify needed management actions and to prioritize regional funding for management over the remainder of the five year planning horizon.
