Tentek River Delta


IBA Justification

The site was identified as important in 2007 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).

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%) slow but significant deterioration medium
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now some of area/population (10-49%) slow but significant deterioration medium
Biological resource use fishing & harvesting aquatic resources - unintentional effects: subsistence/small scale happening now small area/few individuals (<10%) slow but significant deterioration low
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now some of area/population (10-49%) slow but significant deterioration medium

Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications fire & fire suppression - increase in fire frequency/intensity happening now some of area/population (10-49%) slow but significant deterioration medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
