The influence of riparian management on stream erosion

Many of the conclusions in this chapter can be summarised in an acronym that can be remembered by the phrase " Please Think " — PLS –T. 1. PROCESS — Managers will be most effective in targeting riparian revegetation if they first understand the erosion mechanisms (the processes) that are acting in a particular stream or river reach. 2. LEVERAGE — Once we understand the erosion mechanism, then we can understand the influence (the leverage) that specific revegetation or other riparian management will have on that mechanism. 3. SCALE — Size is everything! Where you are in a catchment and the size (scale) of the channel influences both the erosion processes that operate, and the leverage that riparian vegetation and management have over those mechanisms. 4. TIME — the interaction between the vegetation and the erosion mechanisms will change with time as the vegetation grows, and as the vegetation alters other aspects of the system.
