This quantity incorporates a collection of 14 articles facing various points of biomonitoring and their relation to questions of world swap. the 1st half matters basic elements of biomonitoring. the second one half offers examples of utilized biomonitoring in Germany and Switzerland (changes in species composition, phenologies, crops recovery, adjustments in soil stipulations, and heavy steel concentrations). The 3rd half bargains with climate-related tracking reviews of arctic-alpine and temperate areas of the Northern Hemisphere (mountain peaks and timberline ecotones of the Alps, unfold of unique evergreen broad-leaved crops, phytomass and carbon stability in Svalbard).

Because the means for implementing nature conservation tasks are limited, priorities must be set in order to employ them efficiently. To this end, the following conditions must be fulfilled: • the goal to be attained must be clear, • knowledge of suitable means and measures for goal attainment must exist, and • the costs of the respective measures must be calculated. "To operate efficiently does not mean that costs must be avoided unconditionally; rather, it means weighing costs and benefits against one another for all measures," since costs can be understood as missed benefits or the non-realization of other goals (Hampicke 1991).

4. LEVELS OF SUCCESS MEASUREMENT FOR IMPLEMENTATION, CONDITION, EFFECT, EXPENDITURE AND THEIR PROCEDURES Goal: Different measures of success (especially those of regional planning) and their suitability for nature conservation goal control. Kotter (1989) proposes various measures of success for the evaluation of village renewal measures. He suggests that the effects of the measures should be assessed using indicators, and subsequently be transformed into dimensionless goal fulfilment grades. It is then possible to give percentage values of goal realization and hence to compare the success of different measures.
