Lake Neuchâtel: Corcelettes-Vaumarcus


IBA Justification

The site was identified as important in 2000 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
Red-crested Pochard Netta rufina LC winter 1998 870-2,200 individuals A4i, B1i
Tufted Duck Aythya fuligula LC winter 1998 4,600-9,600 individuals B1i

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2013) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2013 not assessed low negligible
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
Energy production and mining happening now some of area/population (10-49%) no or imperceptible deterioration low
Human intrusions and disturbance happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Pollution likely in long term (beyond 4 years) whole area/population (>90%) no or imperceptible deterioration low
Invasive and other problematic species and genes likely in short term (within 4 years) majority/most of area/population (50-90%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other action Result
Little/none of site covered (<10%) No management planning has taken place Very little or no conservation action taking place negligible
