Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2022) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very high
Residential and commercial development	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	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	medium

Habitat	% of IBA	Habitat detail
Forest	54	Mangrove; Lowland forest - dry evergreen
Marine Intertidal	35
Marine Coastal/Supratidal	10

Land use	% of IBA
