Wildlife Diversity Webinar | Conserving Genetic Diversity of the Big Red Sage

Genetic diversity analysis can help inform how to conserve endangered plants. In this talk, Dr. Sean Hoban with the Morton Arboretum will describe how to develop a conservation genetic project, some common obstacles, and how to interpret results using a recent study. Salvia pentstemonoides (Big Red Sage) is a highly threatened plant native to Texas. There are less than 10 populations, perhaps only 5, in existence. Only two of these populations exceed 100 plants; the remaining populations are all less than 50 plants. The plant is highly charismatic, and can be ordered through some specialty nurseries. It is also beautiful and interesting, and is found in botanic gardens. We performed two research efforts to inform conserving the species: (1) Determine whether small populations have lower genetic diversity and/or higher inbreeding than the larger populations. (2) Compare the genetic diversity in wild populations to those in nurseries and botanic gardens.
