The site was identified as important in 2016 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
Barnacle Goose Branta leucopsis	LC	breeding	2011-2015	475-650 breeding pairs	B3, C2, C6
Eurasian Wigeon Mareca penelope	LC	non-breeding	2011-2015	17,103-22,420 individuals	B1i, C3
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	26,249-32,362 individuals	A4iii, C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2018) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Transportation and service corridors	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Very little or no conservation action taking place	medium

Year	Protected Area	Designation	% overlap with IBA
-	Polder Mijzen	Nature Reserve	15
-	Eilandspolder West	Nature Reserve	23
1966	Eilandspolder Oost	Nature Reserve	48
