NatureServe Global Conservation Status Factors

Range Extent Comments: Only known to occur in the North Kawich Range in Nye County, Nevada at 7500-9000 feet elevation (Reveal and Beatley, 1971).

Area of Occupancy: 1-5 4-km2 grid cells
Area of Occupancy Comments: The maximum range dimension for the Kawich Peak occurrences is 6.9 km (4.3 mi) excluding the most disjunct record with a total estimated area of 1.2+ ha (3.0+ ac) (Morefield, 2001). Range and area for the new Morey Peak occurrences are not known but are likely as small or smaller.

Number of Occurrences: 1 - 5
Number of Occurrences Comments: It is confined to Kawich Peak, North Kawich Range, central Nevada in Nye Co. Known in Eden Creek and Longstreet Creek drainage from four occurrences (Morefield, 2001). Two additional occurrences were found in 2002 on Morey Peak in Morey Canyon, also Nye Co., Nevada (NV NHP).

Population Size Comments: Total estimated individuals are 373+ (Morefield, 2001) not included Morey Peak occurrences.

Number of Occurrences with Good Viability/Integrity: None to few (0-12)

Overall Threat Impact: Unknown
Overall Threat Impact Comments: Grazing by wild horses, mining, and possibly the proposed MX missile system all potentially threaten this species but impact severity and immediacy have not been assessed.

Short-term Trend: Decline of <30% to increase of 25%
Short-term Trend Comments: Trend information is not known, however two new occurrences were found within the same range in Morey Peak in Nye Co. (NV NHP).

Long-term Trend: Unknown
Long-term Trend Comments: Trend information is not known.

Environmental Specificity: Narrow. Specialist or community with key requirements common.

Ecology & Life History
Help
Basic Description: A perennial herb, 2-5 dm tall, with funnel-shaped, blue-violet flowers in bloom late June-July.
Duration: PERENNIAL
Reproduction Comments: Flowering occurs in late-spring to summer (Morefield, 2001).
Terrestrial Habitat(s): Forest/Woodland, Woodland - Conifer
Habitat Comments: Steep, rocky slopes in Pinyon-Juniper woodlands, especially along partially shaded washes. 2300-2750 m elevation. The species occurs in crevices, soil pockets, and coarse rocky soils of felsic volcanic outcrops, boulder piles, steep protected slopes, and drainage bottoms, mostly on north and east aspects, in the subalpine sagebrush, mountain mahogany, and upper pinyon-juniper zones (Morefield, 2001).

Management Summary
Help
Stewardship Overview: Currently, no formal management plan exists for this species. Management recommendations might include discussing protection of this species with the Bureau of Land Management. It has a limited distribution but is locally common at upper elevations of the Kawich Range, and is isolated and remote, with no known active impacts or threats. Currently management includes movement to Nevada Sensitive Species List status. A thorough assessment of potential threats should be undertaken.
