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%)	moderate to rapid deterioration	very high

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	Some limited conservation initiatives are in place	medium

Year	Protected Area	Designation	% overlap with IBA
1998	Voordelta	Site of Community Importance (Habitats Directive)	100
2000	Voordelta	Special Protection Area (Birds Directive)	100
2000	Voordelta	Ramsar Site, Wetland of International Importance	100
