Ditch monitoring at Walland Marsh SSSI (ENRR132)

This report covers 534 ditches that were sampled on Walland Marsh during 1993 and 1994, and represented almost complete coverage of the ditches within the SSSI. The results provided information on the distribution and abundance of ditch flora in different blocks of grazing marsh and across the site as a whole, and establish a base line for future monitoring. Comparisons were made between different areas of grazing marsh, ditches in pasture and ditches in arable land, grazed ditches and ditches in arable land and also between 1985 and 1993/4 survey results.
