In the 1980s the Nature Frame started as a simple zoning of green belts, recreation areas and protected areas. It has progressively been worked out (and formally developed in 1988-89) into hierarchical structure of geo-ecological divides, areas of inner stabilization compensating the influence of land use and urban development and migration corridors. It is usually characterized by the absence of urban and industrial activities. In 1993 the Landscape Management Group of Vilnius University worked out Nature Frame Schemes at regional levels covering all 44 administrative districts and currently it covers 61.4% of Lithuania, varying from 35% - 45% (North Lithuania Plain) to 75% - 80% (Eastern Lithuania), depending on natural conditions and land use. The development of common European Ecological Network started in early 1990s and its main purpose is to preserve biodiversity. General principles and strategy of the Ecological Network in Lithuania were formulated in late 1990s led by Lithuanian Fund for Nature. Criteria and principles of the Lithuanian Nature Frame differ from the criteria and principles of the European Ecological Network, however, when creating Lithuanian Ecological Network the best strategy is to develop and implement it within the existing framework of the Lithuanian Nature Frame. This article provides a general overview of the principles of Lithuanian Nature Frame and Ecological Network and provides a general strategy how to implement the Ecological Network in Lithuania.
