The site was identified as internationally important for bird conservation in 2007 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Jabiru Jabiru mycteria	LC	resident (1998–2007)	1–500 individuals	A4i
A4iii Species group - waterbirds	n/a	unknown (-)	20,000-49,999 individuals	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) is shown below.

State (condition of the key species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (>90%)	good (>90%)	favourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Biological resource use	happen­ing now	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	high
Residential and commercial development	likely in short term (within 4 years)	whole popul­ation/area (>90%)	slow deteri­oration (1–10% over 3 gener­ations)	high

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Most of site (50–90%) covered (including the most critical parts for important bird species)	No manage­ment plan exists, but the manage­ment planning process has begun	The conservation measures needed for the site are being comprehensively and effectively implemented	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
2004	Rio Negro	Parque Nacional - Publico (II)	58
2015	El Ceibo	Reserva Natural - Privado (IV)	1
