Consequences and limits to use of historical hydrobiological data in the current biodiversity context

Abstract

Data on aquatic flora and fauna have been collected over the last two centuries, whilst human impacts on water and habitat quality have been increasing. Though the data have been used mainly by scientists in applied ecology, contemporary social concerns enhance their value for biodiversity issues and management. However, the appropriate use of historical data requires expert analysis of the various archives, taking into account the historical context and scientific aims at the time of collection. Review of historical data is essential for the conservation and efficient, sustainable management of biodiversity.
