The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Mountain Plover Charadrius montanus	NT	winter	2015	5-55 individuals	B1a
Long-billed Curlew Numenius americanus	LC	winter	2018	1,500 individuals	A4, B3a
Loggerhead Shrike Lanius ludovicianus	NT	resident	2020	93 individuals	B1a
Worthen's Sparrow Spizella wortheni	EN	resident	2015	282 individuals	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2021) may differ.

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	moderate (70-90%)	poor (40-69%)	very unfavourable
Shrubland	good (> 90%)	moderate (70-90%)	near favourable
Forest	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	past (and unlikely to return) and no longer limiting	some of area/population (10-49%)	no or imperceptible deterioration	low
Transportation and service corridors	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	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	medium
