Regularity: Regularly occurring
Global Range: Presently known from only two locations in the Rat Island group of the western Aleutian Islands, and probably restricted to this area.
Comments: Open fellfields on windswept, gravelly ridges with sparse vegetaton. The species occurs as scattered, white, often sterile rosettes on seemingly barren patches between heath vegetation.
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 1 - 5
Comments: It is likely that several new EO's will be added when the Rat Islands are more fully explored.
National NatureServe Conservation Status
Rounded National Status Rank: N1 - Critically Imperiled
NatureServe Conservation Status
Rounded Global Status Rank: 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.
Environmental Specificity: Narrow. Specialist or community with key requirements common.
Comments: Restricted to windswept fellfields.
Global Short Term Trend: Unknown
Comments: Not known, but no dramatic changes reported in recent years.
Global Long Term Trend: Unknown
Comments: Not known, but likely to be relatively stable.
Comments: Threat is from small population in highly restricted area, with high degree of natural disturbance (wind swept fellfield).
Artemisia aleutica, the Aleutian wormwood, is a rare species of flowering plant endemic to Alaska. It is known only from the western Aleutian Islands, where it is limited to Kiska and Hawadax Islands in the Rat Island group.
Only 2 populations are known.
Names and Taxonomy
Comments: Distinct species with affinites to A. richardsoniana Besser (B87MUR01AKUS).
