Kii Nagashima islets


IBA Justification

The site was identified as important in 2004 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
Japanese Woodpigeon Columba janthina LC resident 2003 present A2
Japanese Murrelet Synthliboramphus wumizusume VU breeding 2003 present A1
Pleske's Grasshopper-warbler Helopsaltes pleskei VU breeding 2003 present A1

The current IUCN Red List category (shown above) may differ from that which was valid at the time of IBA criteria assessment (2004).

State (condition of the trigger species' habitats)
Habitat Habitat detail Reference area (ha) Actual area (ha) Habitat quantity (% remaining) Habitat quality (carrying capacity) Result
Forest 0 0 good (> 90%) poor (40-69%) unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Human intrusions and disturbance recreational activities happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species likely in long term (beyond 4 years) whole area/population (>90%) slow but significant deterioration medium

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%) 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 low
