River foreshore condition of the left bank, assessed and classed using the Pen-Scott classification method. The Pen-Scott method is a standardised rating technique that classifies foreshore areas along a gradient from pristine (A grade) through to D grade, connoting a ditch. The four grades are further divided into three sub-categories per grade, i.e. A1, A2 and A3. A1: Pristine A2: Near pristine A3: Slightly disturbed B1: Degraded – weed infested B2: Degraded – heavily weed infested B3: Degraded – weed dominated C1: Erosion prone C2: Soil exposed C3: Eroded D1: Ditch - eroding D2: Ditch – feely eroding D3: Drain – weed dominated See specific reports for more information and pictorial examples. See Pen, L.J. and Scott, M. (1995) Stream foreshore assessment in farming areas. Blackwood Catchment Coordinating Group and Water and Rivers Commission (1999) River Restoration Reports No. RR2 and RR3 for foreshore condition assessment methods. Left and right bank are relative to an observer facing downstream.
