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	non-breeding	2011-2015	25,138-30,661 individuals	A4i, B1i, C2
Barnacle Goose Branta leucopsis	LC	winter	2011-2015	23,126 individuals	B3
Lesser White-fronted Goose Anser erythropus	VU	non-breeding	2011-2015	50-88 individuals	A1, C1, C6
Lesser White-fronted Goose Anser erythropus	VU	winter	2011-2015	8 individuals	B2
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	35,222-41,359 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
Human intrusions and disturbance	happening now	whole area/population (>90%)	no or imperceptible deterioration	low
Transportation and service corridors	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Energy production and mining	likely in short term (within 4 years)	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	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	high

Year	Protected Area	Designation	% overlap with IBA
1994	Oudeland van Strijen	Special Protection Area (Birds Directive)	100
1996	Oudeland van Strijen	Nature Reserve	24
2010	Oudeland van Strijen	Natuurbeschermingswet	100
