Applicability of the 'Watershed Habitat Evaluation and Stream Integrity Protocol'(WHEBIP) in assessment of the stream integrity in Bregalnica River Basin

摘要

This paper reports the assessment of the ecological integrity of streams in Bregalnica River Basin with emphasis on river Bregalnica as the biggest and most important watercourse in Eastern Macedonia.The results have principally been derived from remote sensing data and set up in a model build up on Watershed Habitat Evaluation and Stream Integrity Protocol (WHEBIP). WHEBIP effectiveness in predicting ecological integrity of streams has been assessed by correlation analyses derived upon data on macroinvertebrate biotic indices and physico-chemical parameters on 35 localities throughout the basin. The statistical analyses confirmed the capacity of WHEBIP to predict stream site-specific features with great accuracy in the case of Bregalnica. The results obtained in this study contribute towards the improvement of the WHEBIP protocol and in general, promotes applicability of stream integrity assessment tools in setting priorities for integrated watershed management.
