摘要

For purposes of risk management an evaluation of possible impacts of pesticide applications on not agricultural used ecosystems is necessary including their capability to compensate temporary effects. The capability of regeneration depends on the amount of natural habitats and the intensity of agriculture in a landscape. graphical Information System Germany" (ATKIS) the degree of equipping by natural habitats of 475 agricultural landscapes has been calculated. In total the landscapes in Germany are provided with 2,585,170 hectare natural habitats (mean value of the partition of natural habitats per landscape: 7.12%). Field edges (at tracks, streets, forests etc.) contribute with 66 % mostly to the total area of natural habitats, followed by copses with 13%. Further a method to calculate the minimum area of natural habitats necessary for regeneration has been developed. Risk maps were drawn showing that 346 landscapes of 475 (72.8%) exceed their calculated minimum area of natural habitats. In frame of a check of robustness of input data by means of Monte-Carlo simulation with 100,000 random replications 27 of the 346 "positive" landscapes have indicated an instable behavior.
