Amami islands


IBA Justification

The site was identified as internationally important for bird conservation in 2004 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
Japanese Woodpigeon Columba janthina LC resident (2003) present A2
Ryukyu Green-pigeon Treron permagnus LC resident (2003) present A2
Amami Woodcock Scolopax mira VU resident (2003) present A1, A2
Ryukyu Scops-owl Otus elegans NT resident (2003) present A2
Ryukyu Minivet Pericrocotus tegimae LC resident (2003) present A2
Amami Jay Garrulus lidthi VU resident (2003) present A1, A2
Amami Thrush Zoothera major LC resident (1996) 58 birds A1, A2
Ryukyu Robin Larvivora komadori NT resident (2003) present A2

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Forest good (>90%) moderate (70–90%) moderate

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Human intrusions and disturbance likely in short term (<4 years) some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) medium
Residential and commercial development likely in short term (<4 years) some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) medium
Agricultural expansion and intensification likely in short term (<4 years) some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Climate change and severe weather likely in long term (>4 years) most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Some of area covered (10–49%) No management plan exists, but the management planning process has begun Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity low
