The site was identified as important in 2021 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:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Scarlet Ibis Eudocimus ruber	LC	resident	2014	5,000 individuals	A4, B3a
Grey Plover Pluvialis squatarola	VU	non-breeding	2011	1,200 individuals	B3a
Semipalmated Plover Charadrius semipalmatus	LC	non-breeding	2013	2,000 individuals	A4, B3a
Red Knot Calidris canutus	NT	non-breeding	2018-2020	25-5,930 individuals	B1a, B3a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2021) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
