Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2017) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	No management plan exists, but the management planning process has begun	Very little or no conservation action taking place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1966	Tinfunque	Parque Nacional - Publico (II)	57
2004	Toro Mocho	Reserva Natural - Privado (IV)	2

Habitat	% of IBA	Habitat detail
Forest	67	Tropical deciduous forest; Tropical semi-deciduous forest; Tropical semi-evergreen forest
