| Similar to Lake Baikal or Lake Tanganyika, Lake Ohrid harbors endemic species covering the whole food-chain, from phytoplankton and sessile algae (20 species; e.g., Cyclotella fottii), over plant species (2 species; e.g., Chara ohridana), zooplankton (5 species; e.g., Cyclops ochridanus), cyprinid fish (8 species; e.g., Pachychilon pictus), to predatory fish (two trout species; the Ohrid trout complex Salmo letnica, and "Belvica" Salmo ohridanus) and finally its diverse endemic bottom fauna (176 species; e.g. | WIKI |
| There were recorded 68 species of freshwater snails from the Lake Ohrid basin. | WIKI |
| [34] 73.5% (50 species) of the total freshwater gastropod fauna appear to be endemic to the Lake Ohrid basin. | WIKI |
| [35] In total, seven introduced fish species are known from the lake. | WIKI |
| Despite the exceptionally high level of endemism in Lake Ohrid (for example, a third of the 21 native fish species and almost 80% of its 72 mollusc species are endemic), a significant number of non-endemic species are found in Lake Ohrid. | WIKI |
| This includes species, which are mobile (e.g., via water birds) or migratory, such as the European eel. | WIKI |
| [41] The Albanian part of the lake has been designated a separate but corresponding IBA for the same reason, with additional bird species being common goldeneyes, red-crested pochards (Netta rufina) and black-necked grebes. | WIKI |
| The Macedonian side of Lake Ohrid was declared a World Heritage Site by UNESCO at the 3rd Session of the World Heritage Committee in 1979[44] and holds that status under Criterion VII as a superlative natural phenomenon related to its refuge function for relict and world-unique freshwater species, and its rich bird life. | WIKI |
| Due to its size, accessibility and species richness, Lake Ohrid is extremely well-suited to the function of a natural laboratory. | WIKI |
| Although the effects of these human impacts have not been evaluated in detail they are of great concern, as the shallow water sites are particularly rich in endemic bottom fauna and form important spawning grounds for several endemic fish species. | WIKI |

| [59] It further describes the "critical importance" of the last intact marsh on the Lake Ohrid shore, Studenchishte Marsh, in terms of its species composition and ecosystem services such as water quality improvement, carbon storage and flood retention among others. | WIKI |
| Lake Ohrid is a superlative natural phenomenon, providing refuge for numerous endemic and relict freshwater species of flora and fauna dating from the tertiary period. | UNESCO |
| Its oligotrophic waters conserve over 200 species of plants and animals unique to the lake, including algae, turbellarian flatworms, snails, crustaceans and 17 endemic species of fish including two species of trout, as well as a rich birdlife. | UNESCO |
| As a result of its geographic isolation and uninterrupted biological activity, Lake Ohrid provides a unique refuge for numerous endemic and relict freshwater species of flora and fauna. | UNESCO |
| Its oligotrophic waters contain over 200 endemic species with high levels of endemism for benthic species in particular, including algae, diatoms, turbellarian flatworms, snails, crustaceans and 17 endemic species of fish. | UNESCO |
| These include the urgent need to protect the water quality of the Lake and therefore maintain its oligotrophic ecological function; to tackle tourism and associated legal and illegal development and the impacts of development on habitats and species throughout the property, including on the lake shores. | UNESCO |
