NatureServe Status

Global Status: G1
Global Status Last Reviewed: 18Jun2008
Global Status Last Changed: 10Jul1990
Rounded Global Status: G1 - Critically Imperiled
Reasons: Known only from 2 adjacent islands in the western Aleutian Islands. Only 2 populations are confirmed extant. Population numbers appear to be relatively low (fewer than 3,000 individual plants in total), and the populations are in areas of high natural disturbance.
Nation: United States
National Status: N1

U.S. & Canada State/Province Status
Due to latency between updates made in state, provincial or other NatureServe Network databases and when they appear on NatureServe Explorer, for state or provincial information you may wish to contact the data steward in your jurisdiction to obtain the most current data.

NatureServe Global Conservation Status Factors

Range Extent Comments: Presently known from only two locations in the Rat Island group of the western Aleutian Islands, and probably restricted to this area.

Area of Occupancy: 1-125 4-km2 grid cells
Area of Occupancy Comments: Difficult to estimate area of occupancy. If limited to the two populations known to be extant, it is probably less than 4 sq. km.

Number of Occurrences: 1 - 5
Number of Occurrences Comments: It is likely that several new EO's will be added when the Rat Islands are more fully explored.

Population Size Comments: Based on estimate of Talbot in 1985. Reported as scattered individuals in both populations.

Number of Occurrences with Good Viability/Integrity: Very few (1-3)
Viability/Integrity Comments: The two know locations seem to have good viability, absent any changes in environment.Based on estimate of Talbot in 1985. Reported as scattered individuals in both populations.

Overall Threat Impact Comments: Threat is from small population in highly restricted area, with high degree of natural disturbance (wind swept fellfield).

Short-term Trend: Unknown
Short-term Trend Comments: Not known, but no dramatic changes reported in recent years.

Long-term Trend: Unknown
Long-term Trend Comments: Not known, but likely to be relatively stable.

Intrinsic Vulnerability Comments: Sexual reproduction is low (few flowers or fruits ever seen). Long-lived perennial with slow regeneration.

Environmental Specificity: Narrow. Specialist or community with key requirements common.
Environmental Specificity Comments: Restricted to windswept fellfields.
