The site was identified as important in 2006 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2006) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2018) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
-	Vatura Forest Amenity Reserve	Amenity Reserve	-
1941	Vaturu Catchment	Water Dam	1
1989	Koroyanitu Heritage Park	Heritage Park	20
