1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2019) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Transportation and service corridors	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Energy production and mining	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

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Some of site covered (10-49%)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
1965	Deliblatska pescara	Rezervat prirode	48
2006	Labudovo okno	Ramsar Site, Wetland of International Importance	58
2015	Karas-Nera	Predeli izuzetnih odlika	1
