Identified by specialists with ROSPA 0099, Hârtibaciu Plateau has been declared a site of bird fauna importance, with the purpose of maintaining in a favorable state the species of wild birds and their conservation. 

This area is the largest coherent semi-natural area - and probably the best preserved - in the continental biogeographic region of Transylvania. This is a favourite nesting area for the most significant population of the lesser spotted eagle (Aquila pomarina) and the European honey buzzard (Pernis apivorus) in Romania, the highest density being reached south of the Hârtibaciu Valley. 

The protected area is characterized by the scarcity large farms and the abundance of semi-natural lands - extensive grasslands and meadows. The landscape structure is like a mosaic, in which the semi-natural areas alternate with deciduous forests, which is why the biodiversity is very high. The anthropic impact is very low, with few localities in a very large area. 

Here you will find important herds of globally interest, also from endangered species by the European Union level: Ural owl (Strix uralensis), European nightjar (Caprimulgus europaeus), oak middle spotted woodpecker (Dendrocopos medius), Syrian woodpecker (Dendrocopos syriacus), grey-headed woodpecker (Picus canus), the woodlark (Lullula arborea) or the red-backed shrike (Lanius collurio). The population of Ural owl (Strix uralensis), European nightjar (Caprimulgus europaeus), oak middle spotted woodpecker (Dendrocopos medius), woodlark (Lullula arborea) and red-backed shrike (Lanius collurio) are also among the most important in the country.
