Rutland Water

IBA Justification

The site was identified as important in 2007 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Northern Shoveler Spatula clypeata LC passage 2001-2006 586 individuals B1i, C3
Gadwall Mareca strepera LC passage 2001-2006 774 individuals B1i, C3
A4iii Species group - waterbirds n/a passage 2001-2006 26,224 individuals A4iii, C4
A4iii Species group - waterbirds n/a winter 2001-2006 27,833 individuals A4iii, C4

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).

IBA Conservation

IBA conservation assessment
Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2007 very unfavourable high high
Was the whole site assessed? State assessed by Accuracy of information
yes population good

State (condition of the trigger species' populations)
Scientific name Common name Reference population Actual population Units % of population remaining Result
Spatula clypeata Northern Shoveler 550 201 individuals 37 very unfavourable
Mareca strepera Gadwall 1160 251 individuals 22 very unfavourable
Species group - waterbirds A4iii 21919 27833 individuals 100 favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now small area/few individuals (<10%) slow but significant deterioration low
Invasive and other problematic species and genes problematic native species/diseases - unspecified species happening now small area/few individuals (<10%) slow but significant deterioration low
Natural system modifications dams & water management/use - abstraction of surface water (unknown use) likely in short term (within 4 years) majority/most of area/population (50-90%) very rapid to severe deterioration high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation 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
