NatureServe Status

Global Status: G1
Global Status Last Reviewed: 24Oct2007
Global Status Last Changed: 31Dec1998
Rounded Global Status: G1 - Critically Imperiled
Reasons: Dubautia waialeale is almost totally restricted to the Waialeale summit bog on the island of Kauai, Hawaii. Only a single plant has been found away from Waialeale; >3,000 plants have been estimated for the Waialeale summit after further survey of the area. The species is threatened by feral pigs, goats, and invasive alien plants.
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: Endemic to Kauai Island, Hawaii from less than 25 sq km.

Area of Occupancy: 1-25 4-km2 grid cells
Area of Occupancy Comments: The area of occupancy is estimated to be >1 sq km. This species is known from five occurrences.

Number of Occurrences: 1 - 5
Number of Occurrences Comments: 5 total extant occurrences located on the island of Kauai (1996-2007) (HBMP 2007). Two recorded occurrences, both extant; one consists of only a single plant. The other occurrence/subpopulation is made up of several hundred individuals. The occurrence with hundreds of inviduals is at the summit of Waialeale and the other is at the opposite end of the Alakai Plateau and consists of one individual (Russell 2004). Three additional EOs are also located on the Waialeale Summit Bog area (Wood K.R. 2007)

Population Size Comments: 500-700 plants estimated. This number may rise with further survey of the Waialeale region. The U.S. Fish and Wildlife Service reported approximately 800 individuals in 2004 (Russell 2004). After further survey it is estimated that there are >3,000 individuals. (Wood K.R. 2007)

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact: Very high - high
Overall Threat Impact Comments: Threatened by feral pigs, goats, and invasive alien plants. Dubautia waialealae is threatened by feral pigs that adversely modify habitat (Russell 2004, Russell 2002). While introduced plant species are not as large a threat to Dubautia waialealae as feral pigs, there are a few species that are invading the bog habitat including Juncus planifolius and Andropogon virginicus (broomsedge) (Russell 2004, Russell 2002).

Short-term Trend: Decline of <30% to relatively stable
Short-term Trend Comments: Pig damage was observed on at least ten percent of the entire remaining population (Russell 2002). At current rates of damage, the remaining population will decline dramatically in the foreseeable future (Russell 2004, Russell 2002). Further, about half of the larger subpopulation has been fenced to prevent pigs from getting to the site. However, pigs do still break in where the fencing is weak in between fence maintenance work and eat this species (Russell 2004).

Long-term Trend: Unknown

Environmental Specificity: Unknown
