Data Zone
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 |
|---|---|---|---|---|
| Red-crowned Crane Grus japonensis | VU | breeding (2003) | present | A1, A3 |
| Latham's Snipe Gallinago hardwickii | NT | breeding (2003) | present | A3 |
| Grey-tailed Tattler Tringa brevipes | LC | passage (2003) | present | A4i |
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.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2015 | moderate | high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | - | |
| 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 |
| Pollution | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Human intrusions and disturbance | likely in long term (>4 years) | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | medium |
| Residential and commercial development | past (and unlikely to return) and no longer limiting | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| 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 |
