The loch fleet and other catchment liming programs

Abstract

The circumstances under which catchment liming is an advisable economic alternative to direct water liming are described, as are research and operational experiences of catchment liming, drawing mainly on the Loch Fleet Project results and other European data. The arguments for and against catchment liming as a means of restoring acidified aquatic habitat are presented. In general, it is concluded that there are conditions, such as lakes with short retention times and/or where stream spawning fish species are involved, where catchment liming is a sensible option.
