- A lately revealed research has steered trying on the wild populations of a key fowl species as a gauge for ecosystem well being in Borneo.
- The researchers discovered six Bornean fowl species are sturdy indicators of intact forests, three species indicated the state of a depleted forest, one for combined gardens, and none for oil palm plantations.
- The outcomes endorse the final development discovered throughout the tropics of a big discount in fowl species richness, from complicated pure and previous secondary forest constructions to simplified monoculture habitats.

JAKARTA — To enhance ecosystem administration in Borneo, have a look at the inhabitants tendencies of key fowl species on the island, researchers say.
The scientists from the Heart for Worldwide Forestry Analysis (CIFOR) and Indonesia’s Tanjungpura College have discovered that six Bornean fowl species are sturdy indicators of intact forests — combined dipterocarp and heath — in West Kalimantan, a province in Indonesian Borneo. They embody the nice argus (Argusianus argus), the cinnamon-rumped trogon (Harpactes orrhophaeus), and the rhinoceros hornbill (Buceros rhinoceros).
The research, revealed April 29 within the journal World Ecology and Conservation, additionally discovered that three different species had been good indicators of a depleted forest state: the mustached babbler (Malacopteron magnirostre), the brown-cheeked bulbul (Alophoixus bres) and the chestnut-backed scimitar babbler (Pomatorhinus montanus). The white-bellied erpornis (Erpornis zantholeuca), in the meantime, was discovered to be an excellent indicator species for combined gardens, whereas none had been indicators for oil palm farms.
The researchers performed subject campaigns throughout West Kalimantan, a area that represents “an historical deforestation entrance and illustrates a gradient of fragmentation, from the extra forested inside to the extra developed central and west areas,” they write.
The sampled websites within the research coated a lowland area of round 90,000 sq. kilometers (34,750 sq. miles) with numerous forest varieties, ranging between intact forests to fallows to smallholder rubber/oil palm farms and combined gardens, and industrial oil palm plantations. The researchers recorded a complete of 10,519 particular person birds of 214 species, virtually 90% of the 241 recognized lowland forest species for Borneo Island.
“Our outcomes endorsed the final development discovered throughout the tropics of a big discount in fowl species richness, from the complicated pure and previous secondary forest constructions to the simplified monoculture habitats,” Trifosa Iin Simamora, a researcher at CIFOR, wrote within the paper.
They discovered that the conversion of forest to fallow phases lowered fowl species richness by 18%, whereas forest conversion to smallholder oil palm lowered fowl species richness by 73%, and conversion from forest to a monoculture industrial oil palm panorama lowered richness by 82%.
Eighty % of the fowl species most popular an intact forest setting, whereas the economic oil palm websites had been essentially the most averted vegetation for all fowl species, with solely 6% of birds adapting to this land use. Farm-dependent species additionally had little conservation worth as per IUCN requirements, in keeping with the research.
The paper discovered 28 forest-dependent fowl species, 54% of them listed as susceptible or near-threatened on the IUCN Crimson Record, and 74% subsisting on a single merchandise weight-reduction plan, emphasizing their vulnerability to habitat disturbance.
“Our outcomes spotlight the relative impacts of various agricultural practices and land makes use of on the potential conservation outcomes of forest birds, notably the necessity to take into account the mixing of fragmented habitats into panorama administration schemes to keep up a sure stage of forest fowl variety within the agricultural matrix,” Simamora wrote.
Borneo, the third-largest island on this planet, is taken into account a big biodiversity evolutionary hotspot and incorporates the best stage of mammal and plant species richness in Southeast Asia. It’s additionally house to some 670 fowl species, of which 42 are discovered nowhere else on Earth, and 46 are near-threatened.
Logging, mining and conversion to monoculture agriculture have drastically impacted Borneo’s rainforests, and modified panorama construction by means of fragmentation and habitat loss.
The researchers mentioned understanding the inhabitants tendencies of those key fowl species could possibly be used to observe habitat high quality and well being of forest agriculture panorama mosaics and enhance the effectiveness of administration, conservation and monitoring sooner or later.
“Sustaining such panorama options would require the strengthening of present panorama administration, by means of methods to advertise the sustainable use of bird-friendly habitats,” Simamora wrote.
