Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2016-07-29
Assessor(s): Daveta, M. & Rivers, M.C.

Justification:
Acacia mathuataensis is an endemic tree from Vanua Levu, Fiji. It is considered Endangered as the area of occupancy is less than 500 km2, it is found in two locations and experiences continuing decline in habitat extent and quality due to fires, agricultural and urban development. It also has fewer 500 individuals, and there are currently no in situ or ex situ conservation action for this species.

Geographic Range [top]

Range Description:Acacia mathuataensis is an endemic species to Vanua Levu, Fiji. Until recently this species was only known from the type collection of 1947, from the summit of Mt. Numbuiloa, east of Labasa, Vanua Levu. Another location on Vanua Levu has now been identified (Fiji Red List Workshop, July 2016). The area of occupancy is less than 500 km2.

Population [top]

Population:The population size is more than 250, but fewer than 500 mature individuals.
Current Population Trend:Unknown
Additional data:
Number of mature individuals:251-499

Habitat and Ecology [top]

Habitat and Ecology:Acacia mathuataensis is a spreading tree up to 6 m. high, apparently rare in dense crest thickets at an elevation of 500-590 m (Smith 1985)
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: There is no known use or trade for this species. It might have some traditional use, as other species within the genus Acacia are used for face painting in traditional dances.

Threats [top]

Major Threat(s): Acacia mathuataensis is threatened by fire, agricultural expansion and urban development.

Conservation Actions [top]

Conservation Actions: There are currently no conservation actions in place for the species and it is not in any protected areas. Conservation action recommendations include i) ex situ establishment, ii) protected area, conservation and management plan, iii) enhancement planting, and iv) awareness and engagement of land owners and regulatory authorities. In addition further research is needed into the population distribution and trends, ecology and ecosystem services and the propagation methods.
