I. Ecological importance of riparian zones

There are a multitude of interactions that take place between streams and forests. Water temperature in streams is moderated by shading which influences production. Leaf litter and coarse woody debris provide allochthonous inputs as food sources for aquatic organisms and habitat structure respectively. The presence of vegetation close to streams moderates sediment transfers within streams (in part by strengthening bank stability) as well as surface flow regimes. Biogeochemical cycling - the cycling of nutrients among surface/ground waters and forests is heavily influenced by the riparian environment.

It is not hard to imagine that changes in the structure of riparian zones by various anthropogenic activities would potentially result in major impacts on the ecology of forests and streams. The question is then, are these impacts inherently 'harmful' to the biological integrity of riparian ecosystems? If so, what are the cost/benefits of implementing best management practices (BMPs)?
