VU
Scarlet-collared Flowerpecker Dicaeum retrocinctum



Justification

Justification of Red List Category
This species occurs within a small, severely fragmented and declining range, and populations are suspected to be declining rapidly as a result of the destruction of lowland forest. It is therefore listed as Vulnerable.

Population justification
The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification
Populations throughout its range are suspected to be declining rapidly as a result of continuing habitat clearance and degradation.

Distribution and population

Dicaeum retrocinctum is endemic to the Philippines where it was thought endemic to Mindoro until the early 1990s when it was surprisingly discovered on Panay and Negros (Collar et al. 1999). On Mindoro it was formerly abundant and still considered fairly common as recently as the 1980s. Data from 1991 surveys show that it remains common in one or two remnant forest tracts on the island but has declined steeply elsewhere. Numbers on Negros, where it is known from just two sites, may be very small. The size of the Panay population is unknown.

Ecology

It inhabits closed canopy forest, chiefly below 1,000 m but occasionally up to 1,200 m. It also occurs in secondary and logged forest, forest edge and occasionally well-cultivated areas. However, it appears generally intolerant of highly degraded habitat, although it does frequent fruiting or flowering trees in forest patches and scrub.

Threats

Extensive lowland deforestation has occurred on all three islands. In the late 1980s, it was estimated that just 120 km2 of forest remained on Mindoro, with a very small proportion below 1,000 m. On Negros 4% and on Panay 8% of the land area remains forested. Several key sites on Mindoro are threatened. Siburan suffers from encroaching slash-and-burn agriculture by locally resettled people and occasional selective logging. Dynamite blasting for marble is a threat to forest at Puerto Galera.

Conservation actions

Conservation Actions Underway
The forest at Siburan is effectively part of the Sablayan penal colony and is included in the F. B. Harrison Game Reserve. Site-conservation actions and a Forest Management Plan were produced by the local stakeholders for the Sablayan forests (including Mt. Siburan) and these are now being implemented. More conservation actions are planned for Mt. Siburan. IBA Monitoring System was set up in the Mt. Siburan area in May 2007 involving the local partners: LGU Sablayan, DOJ-SPPF, DENR, SASAMAKA (a local NGO) and Haribon Foundation. Funding has also been provided for conservation initiatives at Puerto Galera and a conservation education programme has been started at Malpalon. It has been recently recorded in Mt Iglit-Baco National Park (Mindoro), the nominally protected North Negros Forest Reserve, the proposed Central Panay Mountains National Park and the Mt Talinis/Twin Lakes area on Negros, which has been proposed for conservation-related funding.

Conservation Actions Proposed
Conduct further surveys to establish its distribution and status on Negros and Panay. Establish formal, managed protected areas to conserve remnant forest at Malpalon and Puerto Galera. Extend Mt Iglit-Baco National Park to encompass remaining lowland forest tracts. Devise and implement a management plan for the forest at Siburan that reconciles biodiversity conservation with its role as a prison.
