NATURE, PARTICULARLY THE INSECT FAUNA OF LADOGA AND OLONETS-KARELIA

The geology, vegetation, entomological studies, postglacial immigratio n of insects and characteristics of the insect fauna in southern Russi an Karelia are reviewed, with examples of eastern and southern plant a nd insect species recorded in Russian Karelia, but not recorded or rec orded to very limited extent in southern Finland. The management of fo rests and agriculture in Russian Karelia have been, during the Soviet period much less effective, and thus habitats have retained more diver sity than in southern Finland. Recent studies indicate that many speci es considered threatened in Finland occur abundantly in Russian Kareli a.
