Assessment Information [top]

Red List Category & Criteria:

Vulnerable A2c+3c+4c;C2a(i) ver 3.1

Year Published:

2008

Assessor/s:

BirdLife International

Reviewer/s:

Bird, J., Butchart, S. & Crosby, M.

Justification:
This species qualifies as Vulnerable because it has a small, seriously fragmented population and is declining rapidly as a result of lowland deforestation.

Geographic Range [top]

Range Description:	Eurylaimus steerii is endemic to the Philippines, where it is known from Mindanao and neighbouring Dinagat, Siargao and Basilan (including the islets of Poneas and Malamaui). Formerly widespread and fairly common, documented records since 1980 derive from just five sites, three on Mindanao (southern Zamboanga Peninsula, Mt Apo and Bislig) and one on each of Poneas and Siargao, indicating that it is now uncommon and local.

Population [top]

Population:	Preliminary population estimate requiring further documentation
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits the lower and middle storeys of primary and adjacent or admixed secondary forest, generally well below 1,000 m but occasionally up to 1,200 m. There are occasional records from mangroves and even scrub forest on dry, rocky substrates.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Its entire range has suffered extensive lowland deforestation. In 1988, forest cover had been reduced to an estimated 29% on Mindanao, most of it above 1,000 m. Most remaining lowland forest is now leased to logging concessions or mining applications. Dinagat has been virtually totally deforested owing to illegal logging and chromite surface-mining and little forest remains on Siargao, Basilan or Malamaui. Forest at the key site of Bislig is being cleared under concession and re-planted with exotic trees for paper production. Forest fires, associated with insurgency, are a problem on the Zamboanga Peninsula.

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway There are recent records from two protected areas, Mt Apo Natural Park and Siargao. In addition, there are pre-1980 records from Mt Hilong-hilong Watershed Reserve, the Basilan Natural Biotic Area and Mt Matutum Forest Reserve, which is proposed for national park status. Conservation Actions Proposed Identify and survey remaining lowland forest tracts, particularly on Siargao and around Mts Hilong-hilong, Sugarloaf, Matutum and Mayo (on Mindanao) to establish its current distribution and status. Investigate its reported use of mangroves and research its ecological requirements. Propose sites supporting key populations for protection, where appropriate. Ensure that proposed protected areas are gazetted and adequately protected.
