Riparian buffer strips are fenced off areas of grasses, shrubs and trees planted alongside watercourses. In-field buffer strips are areas of planted grasses, shrubs and trees/ uncultivated or undrilled areas along field boundaries or across fields. Bids for these measures are considered for anywhere in the Upper Aire catchment. Please account for fencing that encloses the entire buffer strip when considering your bid. For instances where walls, hedgerows or fencing currently exist and would act to protect the proposed buffer strip from one side, or for riparian buffer strips adjacent to the river bank, single fencing only may be required. You do not need to make a separate bid for fencing.
