Species Scientific Name Mentzelia packardiae
Federal Listing Status Species of Concern
State Listing Status Threatened

Ecoregions

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Special needs

Packard's mentzelia occurs on volcanic ash high in potassium. This species grows on loose slopes at altitudes of approximately 2700-5250 feet.

Limiting factors

Mining, recreational and off-road vehicle activities, and road construction utilizing ash substrate threaten this species.

Data gaps

Conduct common garden studies and investigate genetics behind population variation. Determine the size and longevity of the seed bank. Collect and store seeds at Berry Botanic Garden. Develop propagation and transplanting protocols.

Conservation actions

Minimize road construction into side canyons and mining activity near Packard's mentzelia. Minimize pesticide spraying along local roadways before and during the blooming period, which threatens pollinators. Monitor populations annually.
