Current Research Summary
Current Management Summary
| |
Most of the populations occur on BLM land. |
Research Management Needs
| |
Continued monitoring of populations, studies of their ecology, ex situ propagation protocols and re-introduction feasibility studies. |
Ex Situ Needs
| |
Seeds have been germinated in the greenhouse, but plants did not survive. Protocol must be developed. |
