Abstract

An extensive survey of the River Lune using River Habitat Survey (RHS) was commissioned to assess the habitat quality of the Lune for salmonid fish. The main river on the Lune and tributaries were divided into 500m sections. A sample of 103 sections (25% of the total classified length) was randomly selected and surveyed in February/March 99. A Habitat Modification Score (HMS) describing the level of habitat modification was derived for each site and compared to the whole reference network and to rivers of similar types in Britain. The analysis of Habitat Modification scores show that more than 70% of the sites on the catchment are predominantly unmodified and very few sites are significantly modified (less than 10% of the sites). The analyses of the data collected suggest that although river habitats are altogether of good quality, the natural processes within the catchment may reduce spawning habitats for salmonids. The river processes appear to be driven by natural forces, although land-use is likely to impact on the levels of run-off. Further analyses using fisheries data on the Lune will investigate the relationship between the major environmental dimensions and fish distribution on the catchment.
