Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Stenogyne angustifolia
Taxonomic Comments: Genus endemic to Hawaiian islands, species now restricted to Hawaii island; historical occurrences on Maui & Molokai. Weller (in Wagner et al. 1990) is not recognizing any of Sherff's varieties, nor is Kartesz (1994 checklist and 1999 Floristic Synthesis). USFWS originally listed S. angustifolia var. angustifolia as endangered in 1979; the Oct. 31, 1996 list erroneously listed only the full species; this was corrected in the 1998 and 1999 lists; however, the Pacific Islands Office of the U.S. FWS submitted a draft notice of taxonomic change, which has not yet been published, but which will notify the public that FWS no longer recognizes the varieties and that all entities identified as S. angustifolia are protected under the Act (Christa Russell, Coordinator for Plant Conservation, U.S. FWS, Pacific Islands Office, pers. comm. July 2000).

NatureServe Status

Global Status: G2
Global Status Last Reviewed: 23Oct1996
Global Status Last Changed: 23Nov1996
Rounded Global Status: G2 - Imperiled
Reasons: Recorded from the islands of Molokai, Maui, and Hawaii, but apparently extirpated on Molokai and Maui. Although tens of thousands of plants remain on the island of Hawaii, almost all of them are on the Pohakuloa Training Area (a military training area), in an area about 14 km across. Threats to the species include habitat degradation by alien animals and plants, and human disturbance. Fires have burnt through the heart of S. angustifolia's habitat in the past; however, the species' tolerance to fire is not yet clear.
Nation: United States

NatureServe Global Conservation Status Factors

Range Extent Comments: Hawaii Island; historical range included Maui & Molokai.

Number of Occurrences: 6 - 20
Number of Occurrences Comments: 9 CURRENT POPULATIONS; APPROXIMATELY 12 HISTORICAL RECORDS.

Population Size Comments: Population estimates are difficult to make because of vegetative reproduction.

Overall Threat Impact Comments: Anthropogenic fire from artillery training and public hunting may threaten the survival of this species, as may trampling and disruption from feral ungulates, especially pigs. Competition from alien plants, especially fountain grass, may also threaten establishment of Stenogyne angustifolia. Despite its apparent health, the population [at Pohakuloa Training Area] remains imperiled due to low numbers and restricted habitat. (Aplet and Shaw [no date]).

Short-term Trend Comments: Aplet and Shaw (no date) believed that the Kipuka Kalawamauna (Pohakuloa Training Area) population is currently expanding. The same authors consider the entire area [Kipuka Kalawamauna] as one population.
