Data Zone
The site was identified as internationally important for bird conservation in 2021 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 |
|---|---|---|---|---|
| Mountain Plover Charadrius montanus | NT | winter (2015) | 5–55 birds | B1a |
| Long-billed Curlew Numenius americanus | LC | winter (2018) | 1,500 birds | A4, B3a |
| Loggerhead Shrike Lanius ludovicianus | NT | resident (2020) | 93 birds | B1a |
| Worthen's Sparrow Spizella wortheni | EN | resident (2015) | 282 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2023) is shown below.
