Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2004
Date Assessed: 2009-08-10
Assessor/s: Bell, B., Tocher, M., P., Waldman, B. & Angulo, A.
Reviewer/s: Chanson, J.S. & Hoffmann, M.
Justification:
Listed as Vulnerable because it is known from only two restricted locations, and there is the ongoing potential threat of invasive predators and infection with the disease chytridiomycosis.
History:
2004 Vulnerable

Geographic Range [top]

Range Description: This species is confined to Maud Island, Marlborough Sounds, South Island, New Zealand. In 1997, 300 individuals were translocated to Motuara Island, where it seems to have been established successfully.

Population [top]

Population: This species' population is estimated at between 27,500 and 39,500 individuals in a 16-ha forest remnant on Maud Island. The founder population on Motuara Island  is estimated to be comprised of at least 150 frogs (Tocher and Pledger 2005).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It can be found in coastal forest, mostly in deep boulder banks on lower slopes. It lays large unpigmented eggs in damp situations on the ground, which then undergo direct development without a larval stage.
Systems: Terrestrial

Threats [top]

Major Threat(s): The introduction of mammalian predators, such as Rattus rattus and Mustela erminea, represents a major potential threat to this species. Disease (chytridiomycosis) also represents a possible threat, since it has recently been identified in the closely related L. archeyi.

Conservation Actions [top]

Conservation Actions: NZ Department of Conservation (DOC), through its Native Frog Recovery Group and Native Frog Recovery Plan, administers conservation management of the species and permits appropriate species research. Regular population monitoring and a habitat restoration programme are needed. The colonization of the islands by introduced mammalian predators must be prevented.
