 abstract={Investigations of the forest-island vegetation were conducted in the agricultural landscape of the Jorka river basin, within the Masurian Lakeland (north-eastern Poland). Eight forest islands of varying size (from 0.125 ha to 35 ha) were examined. Four of the greater ones represented planted pine forests (80-100 years old) and the remaining four – birch and aspen woods, naturally grown in deforested but not cultivated places. Lower layers of vegetation were indicative of a more or less advanced processes of development toward the Pino-Quercetum (Kozł. 1925 em. Mat. et Polak. 1955) association. In this report, a geographic and geobotanic character of the investigated area was given, as well as a general characterization of forest islands and their edges. The studied ones were very closely examined.},
