The site was identified as important in 2009 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 (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2010) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	whole area/population (>90%)	slow but significant deterioration	high
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	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 areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
1991	Yalujiangbinhaishidi	Nature Reserve	54

Habitat1	Habitat detail	% of IBA
Artificial/Aquatic & Marine	Other artificial wetlands, Saltpans	major (>10)
Marine Intertidal		major (>10)
Marine Neritic		major (>10)
Artificial/Terrestrial	Arable land, Rice paddies, Abandoned farmland, disturbed ground	minor (<10)
Marine Coastal/Supratidal		minor (<10)
