Country: New Guinea

Administrative region: Papua (Province)

Central co-ordinates: 1.44281 S, 132.02200 E

Qualifying IPA Criteria

A(iii)Site contains one or more highly restricted endemic species that are potentially threatened

IPA assessment rationale

Two plant species endemic to the Teminabuan TIPA. The palm Areca mandacanii and ginger Alpinia porphyrea.

Site description

The varied topography and geology of the area means that there are a range of habitat types present from mangroves and swamp forests to limestone karst and sandstone ridge forest. Rivers flow from ridges to the sea ensuring the area also supports a riverine flora. This TIPA encompasses the small town of Teminabuan with a population size of 19,491 at the 2020 census. This is the administrative capital of South Sorong regency. This area includes the Nature Recreation Park of Beriat that has protected status and is monitored by BKSDA, the government conservation agency. The protected area covers little swamp forest habitat and no mangroves.

Botanical significance

Two plant species are endemic to the Teminabuan TIPA: Areca mandacanii (Arecaceae) and Alpinia porphyrea (Zingiberaceae). The site has an endemic weevil Pachyrhychus faisali (Bollino 2023), two freshwater crayfish Cherax woworae (Pakota et al. 2023) and Cherax pulcher (Widyasari et al. 2021) and the rainbowfish Melanotaenia sembrae (10.26028/cybium/2015-392-003).
Also, likely (and confirmed to be) home to populations of species first described around Sorong, these Sorong populations highly threatened by city expansion, oil palm, logging etc.

Habitat and geology

Mangroves, swamp, limestone karst and sandstone ridge forest.
Mainly two ecoregions; Southern New Guinea lowland swamp forest and New Guinea mangroves but borders Vogelkop-Aru lowland rainforest.
Underlying geology marl, siltstone, limestone and grewacke to marine sedimentary further inland (https://portal.onegeology.org/OnegeologyGlobal/).

Conservation issues

Oil palm plantations have been established to the east and west, and forest loss due to logging is visible along roads (Global Forest Watch 2024).
The Southern New Guinea swamp forest ecoregion is predicted to lose species due to climate change irrespective of increased deforestation (Cámara-Leret et al. 2019).

Ecosystem services

Species used by people are particularly threatened in the Southern New Guinea swamp forest ecoregion (Cámara-Leret et al. 2019).
These forests support major aboveground carbon stocks and blue carbon stocks in the mangroves .
