Pennine Environmental Solutions can provide a slope maintenance grass cutting programme. This predominantly consists of cutting grass on the crest and sides of a bank. If there are problems with weeds or scrub developing on the area between the bank then this will be cut. The vegetation is cut in order to control weeds and encourage the growth of healthy grass which, in turn, promotes stability. When the embankments are overtopped, long grass can result in root structure deterioration and instability increasing erosion. Annual weeds equal bare ground and erosion in winter season, so these need to be controlled.
