In July 1998 the co-ordination of IENE was taken over by the Swedish National Road Administration. Five international IENE meetings has been arranged since 1996 giving good opportunity for the dissemination of various research results and practical solutions. In a new action of the COST program of the European Community, a State of the Art Report on habitat fragmentation at European level (June 2000), a European Handbook on Defragmentation (autumn 2002) and an on-line database (autumn 2002) will be produced by 11 participating countries. The usefulness of co-operation is illustrated with the summaries of two presentations from the 5th IENE meeting. Progress in protecting wildlife from transportation impacts in Hungary Hungary is located in the Eastern part of Central Europe. Two-third of its territory is plain along two main rivers, the Danube and the Tisza, one third is hilly. The geographical location and the historical pattern of the existing transportation networks determine the considerable EastBWest and NorthBSouth transit traffic. In Hungary 9 national parks encompass most of the country's natural heritage. During the last decade wildlife protection has become an important issue in Hungary and habitat fragmentation due to transportation is taken into consideration. Measures have already been taken: amphibian tunnels were built under existing roads, and there are new game tunnels and two green bridges. Knowledge transfer is essential on different fields of transport related environmental protection, therefore Hungary takes part in IENE and COST 341. International co-operation stimulates research activity, for example there is a new program of amphibian road kill survey, several case studies are under work in addition to the National State of the Art Report from which we present here the mapping of fragmentation.
