Bukit Bahar - Tajau Pecah


IBA Justification

The site was identified as important in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Malay Crestless Fireback Lophura erythrophthalma CR resident 2003 present A1
Large Green-pigeon Treron capellei VU resident 2003 present A1
Short-toed Coucal Centropus rectunguis VU resident 2003 present A1
Wallace's Hawk-eagle Nisaetus nanus VU resident 2003 present A1
Sumatran Drongo Dicrurus sumatranus LC resident 2003 present A2, A3
Large-billed Blue-flycatcher Cyornis caerulatus VU resident 2003 present A1
Blue-masked Leafbird Chloropsis venusta NT resident 2003 present A2, A3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2004).


IBA Conservation

IBA conservation assessment
Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2012 unfavourable high high
Was the whole site assessed? State assessed by Accuracy of information
yes habitat good

State (condition of the trigger species' habitats)
Habitat Habitat detail Reference area (ha) Actual area (ha) Habitat quantity (% remaining) Habitat quality (carrying capacity) Result
Forest 80000 63000 - moderate (70-90%) unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming happening now some of area/population (10-49%) very rapid to severe deterioration high
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) likely in short term (within 4 years) small area/few individuals (<10%) slow but significant deterioration low
Biological resource use logging & wood harvesting - unintentional effects: subsistence/small scale happening now some of area/population (10-49%) very rapid to severe deterioration high
Human intrusions and disturbance war, civil unrest and military exercises happening now some of area/population (10-49%) no or imperceptible deterioration low
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now some of area/population (10-49%) very rapid to severe deterioration high
Residential and commercial development housing and urban areas happening now some of area/population (10-49%) moderate to rapid deterioration high
Transportation and service corridors roads and railroads happening now small area/few individuals (<10%) slow but significant deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Whole area of site (>90%) covered by appropriate conservation designation A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity high
