The flora of Macedonia is represent

The flora of Macedonia is represented with around 210 families, 920 genera, and around 3,700 plant species. The most abundant group are the flowering plants with around 3,200 species, which is followed by mosses (350 species) and ferns (42).

Phytogeographically, Macedonia belongs to the Illyrian province of the Circumboreal Region within the Boreal Kingdom. According to the WWF and Digital Map of European Ecological Regions by the European Environment Agency, the territory of the Republic can be subdivided into four ecoregions: the Pindus Mountains mixed forests, Balkan mixed forests, Rhodopes mixed forests and Aegean sclerophyllous and mixed forests.

The fauna of Macedonian forests is abundant and includes bears, wild boars, wolves, foxes, squirrels, chamois and deer. The lynx is found, although very rarely, in the mountains of western Macedonia, while deer can be found in the region of Demir Kapija. Forest birds include the blackcap, the grouse, the black grouse, the imperial eagle and the forest owl.

The three artificial lakes of the country represent a separate fauna zone, an indication of long-lasting territorial and temporal isolation. The fauna of Lake Ohrid is a relict of an earlier era and the lake is widely known for its letnica trout, lake whitefish, gudgeon, roach, podust, and pior, as well as for certain species of snails of a genus older than 30 million years; similar species can only be found in Lake Baikal. Lake Ohrid is also noted in zoology texts for the European eel and its baffling reproductive cycle: it comes to Lake Ohrid from the distant Sargasso Sea, thousands of kilometres away, and lurks in the depths of the lake for 10 years. When sexually mature, the eel is driven by unexplained instincts in the autumn to set off back to its point of birth. There it spawns and dies, leaving its offspring to seek out Lake Ohrid to begin the cycle anew.[17]
