The fauna of the Măcin Mountains, generally less studied, is diverse and has a special importance due to the presence of rare and protected species, according to international regulations.
The great floral and vegetation wealth of the Măcin Mountains is represented by almost 1900 plant species representing approximately half of the Romanian flora in only 0.05% of its surface. 72 species are protected as rare or endangered species, and 27 species are endemic to this region.
Climate The Măcin Mountains National Park lies within temperate-continental climate, with arid influences owed to eastern air current circulation.
The Măcin Mountains are the oldest mountains in the territory of Romania, being created during the Hercynian orogeny. The landscapes of the Măcin Mountains are alike those of Southern Europe due to the presence of sub-Mediterranean and Balkan forests. They also resemble Eurasian steppes, defined by saxicolous vegetation, the Măcin Mountains being the largest such area in Dobrogea and Romania.
Although floristic and fauna studies have been performed in the territory of the park, a lot of ecological relations are still little known. Deeper studies are required pertaining to the succession of vegetation on rocky areas, the evolution of vegetation in different quarry stages, changes in grassland vegetation, vegetation succession in exploited forests, etc.
24 priority habitats have been identified in the Măcin Mountains National Park, 1 of them being unique in the world! (The Dobrogean beech forest).
The Măcin Mountains occupy the NW part of Northern Dobrogea, presenting itself as a row of NW-SE oriented parallel ridges. The altitude of these mountains is between 7 and 467 m (Ţuţuianu Peak). The Măcin Mountains National Park occupies the central and highest area of the Măcin Mountains, which is the oldest geological formation in our country, being a rest of the Hercynic-Cimmerian orogeny.
