[Assessment of the status of aquatic ecosystem alteration: characterization of conservation strategies]

Abstract

This paper evidences the problems that an "environment manager" meets with, when deciding which action to undertake for the conservation of the environment, on the basis of analytical data. A critical point in the evaluation of the state of alteration of an ecosystem, hence in the individuation of the appropriate conservation strategies, is the approach to the management of analytical data. Changing the approach, one can get at different directions, given the same amount and quality of information, by applying the rules properly in every case. The data managed by using the DL.vo 258/2000, approaching the problem by the enclosure 1, "Assessment of the environment quality state", or by the enclosure 2/B B "Quality of water suitable for fishes' life", led to two different indications: the environment manager is expected to decide which of the two solutions is more fit-for-purpose.
