Introduction A unique set of geological, climatic and anthropogenic factors have combined to make the Balkans one of the most biologically intriguing and valuable areas in the Northern Hemisphere. It is now widely appreciated that the Balkans does represent a significant “sump” for, at least, European biodiversity. Despite this, there is still little understanding of the Balkan Biodiversity above the level of simple species description. The extremely high level of endemism in the Balkans compared to other parts of Europe is perhaps the most striking element of comparative patterns of biodiversity (Griffiths, 1998). The Balkans with Macedonia in its central part, contain some of the most extreme environments, and boast the additional diversity of their cave and lake environments which is unsurpassed in other parts. Certainly, compared to other temperate regions on Europe, it is quite outstanding. Coupled with the importance of the geographic location in a transitional zone open to a variety of floral and faunal influences, it is not surprising the notion that the Balkans are indeed the centre of European biodiversity (Reed et al., 2004). Macedonian lakes are of varied origins. The largest lake, Ohrid, is outstanding being a steep-sided graben formed through rifting in a similar fashion to Lakes Tanganyika and Malawi in the East African Rift system, or Lake Baikal. The diversity of taxa in ancient lake environments has also been linked to long-term environmental stability. Levels of endemism for Lake Ohrid are unique and comparable exclusively to other ancient lakes outside Europe. Existing continuously for millions of years, such lakes are distinguished by their rich and unique faunas and undoubtedly constitute “hot spots” of biodiversity (Illies, 1978; Petkovski, 2003). The origin of this apparent species biodiversity is controversial, and several authors have attempted to explain the origin of aspects of these unique biodiversity, albeit with varying degrees of success. Most evoke the clear Paratethyan affinities of the biodiversity of Lake Ohrid and certain elements of that of the karst and, at least in the case of freshwater invertebrates, Paratethyan relictualism must be considered. Many of these species clearly do have their roots in a more ancient, more diverse fauna, and have survived and diverged because of the special conditions that have prevailed there. Although there has been considerable Holocene human impact on the Biodiversity, the absence of 8 major phases of Pleistocene glaciations has allowed particular ecosystems (and particularly aquatic ecosystems) and their associated species to survive for extended periods. Macedonia thus represents an area in which ancient groups have survived and diversified, untroubled by the waves of extinction that accompany glaciations. In addition to this, the Macedonia is clearly important as “meeting point” for the biodiversity of three continents so that, in the case of the less sedentary animal groups, many aspects of Macedonian biodiversity now are believed to have been strongly affected by land bridge exchanges between the Balkans and Anatolia. These exchanges will have been governed by isostatic sea level changes associated with Pleistocene cycles of glaciations. In the case of Macedonia, simple figures of relative species richness do not bring out the real importance of the country in terms of its conservation value. The additional significance of Macedonia as an important region of environmental stability for evolution and the maintenance of biodiversity during Quaternary glacial fluctuations has already been stressed. As in most regions, the effects of human impact on the environment further complicate conservation issues. More recently, there has been marked acceleration in environmental degradation due in a large part to agricultural intensification, but Macedonia is again outstanding in the degree to which forest ecosystems have survived in certain regions, even if in a modified state. Most notably, some of the largest remaining European populations of threatened mammals (Brown Bear, Wolf, Balkan Lynx, Wildcat, Otter, Marbled Polecat, Lesser Mole Rat, Souslik, Chamois and Bats), as well as the European populations of birds of prey, survive in the mountains and gorges of the protected areas, which is direct reflection of the quality of composition and area remaining intact.
