TWINNING SK 2002 IB/EN/03 NATURA 2000 Monitoring of habitats and species of European importance (WP 4.3) Approaches to monitoring of habitats in Natura 2000 sites in Saxony a. „rough monitoring“ –comparison of conservation status for a special habitat type in all pSCI –based on habitat evaluation in management plans –repeated evaluation in intervals of about 5 years Example for a single habitat area in a SCI: Evaluation in management planrepeated evaluation (e. g. after 5 years) Reasons for change Habitat structureABCABCD Species compositionABCABCD ThreatsABCABCD Documentation: - management measures for conservation and development of habitats - necessary investigations or further measures to avoid deterioriation Results: - general trends of conservation status for habitats of European importance over a broad range of sites

TWINNING SK 2002 IB/EN/03 NATURA 2000 Monitoring of habitats and species of European importance (WP 4.3) b. detailed monitoring: –in selected sites representative for a special type of habitat –following standard procedures to allow precise replication and statistical analysis for repeated evaluations Vegetation monitoring: –series of plots arranged randomly (possible for large habitats) –series of sample plots arranged in transects (e.g. for habitats requiring management) –single plots (for small-scale habitats, e.g. springs, rocks or special sites) –complete species list for a single habitat area Monitoring of faunistic indicators: –transects (e.g. for grasshoppers, butterflies, dragonflies, bats) –series of traps (e.g. for beetles, small rodents) –mapping of habitats in greater areas (e.g. for birds, mammals) Results: –evaluation of the effects of habitat management measures and the conservation status of special habitats in a single representative site Approaches to monitoring of habitats in Natura 2000 sites in Saxony

TWINNING SK 2002 IB/EN/03 NATURA 2000 Monitoring of habitats and species of European importance (WP 4.3) General recommendations: –selection of homogenous areas for monitoring in large habitats, especially when they are actively managed –representation of gradients according to altitude, climate, geological and soil characteristics or land use in larger areas (e.g. Muranska planina NP) –exact marking of plots with metal plates and GPS, in addition measuring the exact distance from two remarkable structures (e.g. trees, rocks) and drawing of a small draft map, to enable location of the plots –replication of vegetation plots (e.g ) to validate the results and to avoid undesired accidental effects –selection of representative single plots in small habitats or in addition to transects –investigate faunistic indicators in fixed plots according to (European or nation- wide) exactly defined schemes according to the habitat type Time required: –about one hour per plot (25 m²) for the vegetation survey, and an additional hour per plot for its documentation –about half an hour for marking the plot in the first year, and an additional half an hour for its documentation Recommendations for monitoring habitat types of European importance in the 7 SCI selected for management planning

TWINNING SK 2002 IB/EN/03 NATURA 2000 Monitoring of habitats and species of European importance (WP 4.3) ÚEV Muránska planina b. small-scale habitats suitable for single vegetation plots: Sub-continental peri-pannonic scrub (*40A0) - x Alpine and subalpine calcareous grassland (6170) Rupiculous pannonic grasslands (6190) – x Calcareous rocky slopes (8210) – x Medio-European calcareous scree of hill and montane levels (*8160) – x Of special interest seem to be the large natural forest areas, especially the different types of beech forest, covering a gradient of altitude and a differentiation according to soil characteristic and exposition. Because of the large size of the national park, a complex monitoring system including different gradients and stadiums of forest habitats could be developed. Within the managed habitats, the areas where horses are kept could be interesting if they coincide with occurrence of lowland hay meadows. The sites of the endemic Daphne arbuscula should be included to monitor the favourable conservation status of its habitat.
