The site was identified as important in 2007 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
White-crowned Pigeon Patagioenas leucocephala	NT	resident	2007	unknown	A1
Cuban Amazon Amazona leucocephala	NT	resident	2005	25-350 individuals	A1
Caribbean Elaenia Elaenia martinica	LC	resident	2005	unknown	A2
Yucatan Vireo Vireo magister	LC	resident	2005	unknown	A2
Thick-billed Vireo Vireo crassirostris	LC	resident	2005	unknown	A2
Vitelline Warbler Setophaga vitellina	NT	resident	2005	unknown	A1, A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2014) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Climate change and severe weather	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	likely in long term (beyond 4 years)	small area/few individuals (<10%)	very rapid to severe deterioration	low
Biological resource use	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	likely in long term (beyond 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
Pollution	likely in long term (beyond 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
Geological events	likely in long term (beyond 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
