Zwanenwater & Pettemerduinen


IBA Justification

The site was identified as internationally important for bird conservation 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 List Season (year/s of estimate) Size IBA criteria
Lesser White-fronted Goose Anser erythropus VU non-breeding (2011–2015) 38–41 birds A1, C1, C6
Northern Shoveler Spatula clypeata LC non-breeding (2011–2015) 586–1,340 birds B1i, C3

IBA Conservation

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.

IBA conservation assessment
Year of assessment State Pressure Response
2018 not assessed high medium
Whole site assessed? State assessed by Accuracy of information
yes unset medium

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Pollution happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Invasive and other problematic species and genes likely in short term (<4 years) some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Whole area (>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
