Lehtokallionharjut

Lehtokallionharjut is a nature reserve located in the municipality of Heinola, Finland. It is situated in the Päijät-Häme region and is known for its diverse natural landscapes. The reserve encompasses a significant area of esker formations, which are ridges of sand and gravel deposited by glaciers during the last Ice Age. These eskers create a varied topography, with steep slopes, valleys, and undulating terrain.

The vegetation within Lehtokallionharjut is characteristic of esker environments, featuring a mix of coniferous forests, predominantly pine, and deciduous trees like birch and aspen. In some areas, drier heathland vegetation can also be found, adapted to the sandy soils. The presence of these different habitats supports a variety of flora and fauna. Birdlife is notable, with species typical of forest and open woodland environments present.

The esker formations themselves are of geological interest, offering insights into glacial processes. The landscape also provides recreational opportunities, with trails for hiking and enjoying the natural scenery. The reserve is managed to preserve its ecological values and natural character. Lehtokallionharjut is a protected area intended to safeguard its unique geological and biological features for future generations.
