A replicated, before-and-after, site comparison study in 2005–2012 of farmland ditches in England, UK (FERA 2013) found that managing ditches under an agri-environment scheme had no significant effect on the frequency of emergent vegetation or total plant species richness. After six years, 48–55% of ditches managed under agri-environment rules contained emergent vegetation. There were 6.1–6.5 plant species/ditch (emergent, aquatic and terrestrial combined). These values did not significantly differ from ditches not managed under agri-environment rules: 62% contained emergent vegetation and there were 6.4 plant species/ditch. Additionally, there was no change over time in the proportion of managed ditches that contained emergent vegetation: 39% just before or just after the agri-environment scheme began, then 34% five years later (statistical significance not assessed). Methods: The “Entry Level Stewardship” agri-environment scheme began in 2005/2006. Rules for ditch management included leaving half of the ditch banks uncut every year, and not cultivating within 2 m of the ditch centre. Vegetation in and along ditches was surveyed in 2005/2006, 2011 and 2012. Surveys included 52–170 ditches/year managed under agri-environment rules, and 16–17 ditches/year on farms not participating in the scheme.
