In its analysis and conclusions, the World Heritage Centre observed threats to Lake Ohrid from "decreased water levels, uncontrolled discharge, water pollution due to inadequate wastewater treatment systems leading to evident eutrophication at the mouths of intake rivers, heavy pressures from tourism, and extensive uncontrolled urban development and inappropriate exploitation of the coastal zones." 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. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). , Concern over current and potential deterioration of the World Heritage Site prompted invitation of a joint Reactive Monitoring Mission by the World Heritage Centre, IUCN and ICOMOS in April 2017, which identified a wide range of pressures including from transport infrastructure, traffic, tourism developments, overfishing, sewerage, solid waste disposal, invasive species, both legal and illegal construction, and management of water levels. Tirana, Albania and Ohrid, Macedonia), Deutsche Gesellschaft für Internationale Zusammenarbeit (2015) I, International Union for the Conservation of Nature (IUCN) (2017), World Heritage Centre, ICOMOS and IUCN (2017), S. Stankovic, "The Balkan Lake Ohrid and its living world", Monographiae Biologicae, Vol. Furthermore, it is popular for over 48 species of fish that are found in it. Puka, "The Monitoring Programme of the Lake Ohrid Conservation Project", in, A. Matzinger, Z. Spirkovski, S. Patceva, A. Wüest, "Sensitivity of ancient Lake Ohrid to local anthropogenic impacts and global warming" (Journal of Great Lakes  Deep sediment cores augmented by diverse ecology in the present day offer an extensive archive from which to understand the history of its region over the past 1,200,000 years. Over 20% of the lake's water comes from nearby Lake Prespa, about 10 km (6.2 mi) to the southeast and at 150 m higher altitude than Lake Ohrid. This aim could be reached by controlling household wastewater, which is by far the biggest phosphorus source at the moment. Lake Ohrid lacks an annual deep water exchange which in other lakes can bring complete overturn; plunging rivers are also absent. The Tibetan Plateau has the largest lake cluster in China and in the world. By Sharon Omondi on August 24 2017 in Environment. The lakes are the largest tectonic lakes in Europe. It is located around the provinces of Daisland, Värmland, and Västergötland.  The mission report devised 19 recommendations for Macedonia, which were incorporated under Decision 41 COM 7B.34 of the World Heritage Committee at its 41st Session in Krakow, Poland in 2017.. The volume of the lake is estimated to be 50.7 km3 with maximum depth 289 m and the average depth 151 m. Lake Ohrid is a resource It is considered the … Geography, 13.01.2021 14:00, sabel1234 How tectonic plates formed This position aligns with IUCN advice. The stability due to this salinity gradient allows complete convective mixing events only roughly once every 7 years. Due to its size, accessibility and species richness, Lake Ohrid is extremely well-suited to the function of a natural laboratory. , Both in terms of nutrient concentration (4.5 μg L−1 of phosphorus), as well as biological parameters Lake Ohrid qualifies as oligotrophic. Tectonic lakes The Caspian Sea is a tectonic lake.
