Genetic studies were performed on San Diego Thornmint to help inform restoration practices. In this project, plant material was collected from a number of populations, a collection of seeds was gathered to obtain a representative sample of genetic diversity, a conduction of analysis of rangewide ploidy and isozomes was performed, and quarterly and annual reports were given to indicate progress and accomplishments. The Center for Natural Lands Management (CNLM), National Forest Genetics Laboratory of the USDA Forest Service, and the Applied Ecology Division of the Institute for Conservation Research, San Diego Zoo Global designed and conducted the studies. Project partially funded by SANDAG TransNet EMP Land Management Grant #5001964
