Rosarito and Navalcán reservoirs-La Iglesuela (Tietar valley)


IBA Justification

The site was identified as important in 2011 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Red List Category Season Year(s) Population estimate at site IBA criteria met
Common Crane Grus grus LC winter 2007 min 11,176 individuals A4i, B1i, C2
Black Stork Ciconia nigra LC non-breeding 1996 41-100 individuals B1i, C2, C6
Black Stork Ciconia nigra LC breeding 2009 7 breeding pairs B1i, C2, C6
Great Cormorant Phalacrocorax carbo LC resident 2003 110-222 breeding pairs B1i, C3
Cinereous Vulture Aegypius monachus NT resident 2003 1-10 breeding pairs A1, C1, C2
Spanish Imperial Eagle Aquila adalberti VU resident 2009 4-5 breeding pairs A1, B2, C1, C2, C6
Red Kite Milvus milvus LC resident 2003 13-130 breeding pairs A1, B2, C1, C2
European Roller Coracias garrulus LC breeding 2003 11-110 breeding pairs A1, B2, C1, C2
Dartford Warbler Curruca undata NT resident 2003 121-1,210 breeding pairs A1, C1

The current IUCN Red List category (shown above) may differ from that which was valid at the time of IBA criteria assessment (2011).

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) - agro-industry grazing, ranching or farmin happening now small area/few individuals (<10%) slow but significant deterioration low
Climate change and severe weather drought happening now whole area/population (>90%) very rapid to severe deterioration very high
Human intrusions and disturbance recreational activities happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance work and other activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now whole area/population (>90%) very rapid to severe deterioration very high
Natural system modifications other ecosystem modifications likely in long term (beyond 4 years) majority/most of area/population (50-90%) slow but significant deterioration medium
Pollution domestic & urban waste water - sewage happening now some of area/population (10-49%) moderate to rapid deterioration high
Pollution garbage & solid waste happening now some of area/population (10-49%) moderate to rapid deterioration high
Transportation and service corridors utility & service lines happening now small area/few individuals (<10%) slow but significant deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Little/none of site covered (<10%) No management planning has taken place Some limited conservation initiatives are in place negligible
