Mikomotojima island


IBA Justification

The site was identified as internationally important for bird conservation in 2019 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 Murrelet Synthliboramphus wumizusume VU breeding (2016) min 51 birds A1

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2019) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2019 not assessed high high
Whole site assessed? State assessed by Accuracy of information
yes unset -

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Human intrusions and disturbance happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Invasive and other problematic species and genes happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Energy production and mining likely in short term (<4 years) some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Whole area (>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
