FUTURE DIRECTIONS 
Through my dissertation research at Rancho Santa Ana Botanic Garden, I hope to 
learn more about M. shevockii to aid in its conservation. My research objectives are 
to characterize gene flow (pollen and seed movement) among populations, genetic 
diversity, and population genetic structure. Surveys of known populations and 
potential habitat will continue with the goal of better understanding M. shevockii ’s 
population dynamics and distribution. In addition, pollinator observations, and 
seed banking efforts will continue. A detailed understanding of this species’ 
population biology will inform future conservation actions.
