Anggi Lakes

Country: New Guinea

Administrative region: Papua (Province)

Central co-ordinates: 1.37684 S, 133.92578 E

Area: 67.4km²

Qualifying IPA Criteria

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

IPA assessment rationale

The Anggi Lakes has over 60 endemic plant species found nowhere else in New Guinea. The site contains the known global population of all of these species, which qualifies the site as a TIPA under Criterion A(iii). Some of these endemic species have completed global Red List assessments, of which 6 are Critically Endangered, 6 are Endangered, 5 are Vulnerable. The presence of these globally threatened species qualifies the Anggi Lakes under Criterion A(i). The botanical richness of the Anggi Lakes as compared to the rest of New Guinea has not been explored, but Vollering et al. (2017) defined it as a separate biogeographical region for orchids. Indonesian New Guinea is very poorly collected, so the high number of endemic and threatened species at the Anggi Lakes may be an artefact of it being comparatively well botanically surveyed. The socially, economically and culturally valuable plant species have not yet been surveyed at this site.

Site description

The Anggi Lakes is a pair of large freshwater montane lakes in the north-west of New Guinea within Indonesia’s West Papua province. Each lake is about 8km long. The site is about 50km south of Manokwari and 35km inland from the coast with the Arfak mountains to the north. The elevation is between 1880–2400 metres asl. This hotspot of plant diversity within the Bird's Head region is also one of the best collected sites (Cámara-Leret et al. 2020). However, it was found to be a separate phytogeographical region for orchids (Vollering et al. 2017). The Anggi Lakes themselves are an important freshwater habitat, and are inhabited by people from Arfak, Hatam, and Sougb language groups who use the majority of the lowlands close to the lakes for subsistence agriculture. The area is impacted by repeated burning for subsistence agriculture, the construction of roads and an increasing human population as a result of the creation of the new Pegunungan Arfak Regency.

Botanical significance

The site is of high botanical importance as there are at least 60 vascular plant species which are so far only known from the Anggi Lakes. Of these endemic species which have been assessed so far (19 in total), 13 are considered threatened species: 5 Vulnerable, 6 Endangered, 6 Critically Endangered, with a further 6 assessed as Data Deficient. Among the habitats of particular conservation importance present at the Anggi Lakes are: Lower montane forest, Ericaceae-dominated montane shrubbery with Rhododendron, and mossy high elevation shrubbery with Hydnophytum.

Habitat and geology

The Anggi Lakes lies within the Vogelkop montane forests ecoregion and has a tropical moist montane climate. The elevation ranges from about 1880 metres asl at the lake surface to the highest peak Mount Gwamongga in the south-west which is c.2600 metres asl. The two lakes have differing hydrology and are separated by a mountainous ridge. Anggi Giji has darker water and brown sandy soils, deriving from low-grade metamorphic rocks including shale. Anggi Gida has lighter water and white sandy soils, deriving from high grade metamorphic rocks (quartzite) and granite to the south-east of the lake. The largest river in the area enters Anggi Giji at Irai.
The habitats present in the Anggi Lakes are are: Seasonally fluctuating lake edge: grassland, reedbeds; Lower montane forest; Swamp with Poaceae and Cyperaceae; Dodonea secondary shrubbery; Ericaceous-dominated shrubbery; Mixed montane shrubbery; Regularly burnt areas dominated by Pteridium aquilinum, Baekea frutescens and Poaceae.
The lowlands surrounding the lakes have mostly been cleared for agriculture and settlements. Both lakes are surrounded by roads which have expanded and improved since 2019, making the area more accessible to vehicles. Anggi Giji has a denser human population, and therefore more settlements and roads. The town of Irai is expanding as the capital of the new Pegunungan Arfak Regency. Anggi Gida has a lower human population and therefore more intact habitat.

Conservation issues

The main threats to the habitats in the area are fires linked to agricultural activities and habitat conversion for settlements and new roads. The forest loss around Anggi Giji and the ridge between the two lakes is visible on recent satellite imagery. There forest loss around both lakes that have been ongoing since 2001 according to Global Forest Watch data, but this is higher around the more populated Anggi Giji. Some of these bare slopes may have been deforested before the satellite era, and fires were recorded by some of the early 20th century botanical expeditions. The area is vulnerable to the regional-level threats of climate-change-linked increasing instances of fire and drought. In normal years fires lit in grassland seldom penetrate further than forest edges, but in drought periods fires can be extensive (Hope 2014). Repeatedly burnt areas Anggi is within the ranges of two threatened mammals, the Arfak Ringtail possum (VU) and Ursine Tree Kangaroo (VU) but it is unknown if they occur in the area. The lakes are important for wetland birds, and there are several endemic to northwest New Guinea with a range including the Anggi Lakes: Grey-banded mannikin, Arfak Honeyeater, Arfak Astrapia. A lizard endemic to Anggi (Lobulia vogelkopensis, a single specimen known) was described by Slavenko et al. in 2022. Insects are very undersurveyed and there is likely to be a very high diversity e.g. 8 new Lycanidae (beetles) species and 1 new genus as yet unpublished found in recent surveys.

Ecosystem services

Major ecosystem services are food and fresh water provisioning, and habitats for species. The area is also used for recreation and tourism.
