Pleshcheyevo Ozero National Park
Pleshcheyovo Ozero National Park covers Lake Pleshcheyevo and surrounding areas in the Zalesye part of the Yaroslavl Oblast. The lake is highly popular for recreational use, as an ecological habitat, and is a former resort for the Russian tsars. The lake is located on the central part of the East European Plain, about 130 km northeast of Moscow, in the basin of the Upper Volga. On the southeast shore is the old town of Pereslavl-Zalessky, included in the Golden Ring of Russia.
Topography
The lake itself is 9 km in diameter, and has a 28 km shoreline. It is 25 meters in depth but shallow around the edges. The surrounding shore and region is shaped by the receded glaciers of the last ice age, leaving a moraine-type landscape: gravelly formations of long ridges, extensive wetlands and meandering rivers, and occasional isolated hills. The higher ground above the lake has river valleys with terraces, and the middle region wetlands include peat bogs and other wetlands, including the Berendeyevskoye swamp. The southern area of the park reachedEcoregion and climate
The ecoregion of Pleshcheyovo is Sarmatic mixed forests. This ecoregion is a strip of low forests, lakes and wetlands, running from the Baltic Sea east to the Urals. Forest cover is typically mixed conifer and deciduous trees, with large unbroken tracts under pressure from agriculture. For aquatic habitat, the park is in the "Volga-Ural" freshwater ecoregion, a region that is characterized in general by a high number fish species but relatively few endemics. Of the 65 species of fish in the overall ecoregion, 19 are found in Lake Pleshcheyevo. The development of dams, reservoirs and catchments along the Volga have disrupted spawning sites and favored species adapted to slower moving waters.The climate of Pleshcheyovo is Humid continental climate, warm summer. This climate is characterized by large swings in temperature, both diurnally and seasonally, with mild summers and cold, snowy winters. Average temperatures range from 10 F in January to 64 F in July. Annual precipitation averages 23 inches. Annual snowcover is 13–140 cm, and typical depth is 30–40 cm. Soil in mid-winter freezes to a depth of 1 meter.
