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') at the site:

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2011) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
A4iii Species group - waterbirds	170,000	11,000	individuals	7	very unfavourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	poor (40-69%)	poor (40-69%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Pollution	likely in short term (within 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high
Residential and commercial development	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	likely in long term (beyond 4 years)	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
Little/none of site covered (<10%)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
2000	Fossil Site of Dinosaur Eggs in Gojeong-ri, Hwaseong	천연기념물	12

Habitat1	Habitat detail	% of IBA
Artificial/Aquatic & Marine		major (>10)
Marine Intertidal		major (>10)
