Manage ditches to benefit wildlife Farmland Conservation

A replicated, controlled paired study in 1991-1992 of ditch banks on arable farms in the Netherlands (de Snoo & van der Poll 1999) found higher plant diversity and more important/rare plant species on ditch banks along unsprayed edges of winter wheat compared to those sprayed with pesticides. Ditch banks next to unsprayed edges of winter wheat had 65 plant species and a floristic value of 2,201 (scoring system based on the importance of different plant species in terms of rarity) compared to those sprayed with pesticides (50 species; floristic value 1,181). There was no significant difference on banks along unsprayed and sprayed edges of sugar beet Beta vulgaris (species: 48 and 41, floristic values: 3,616 and 3,029 respectively) and potato crops (species: 46 and 41, floristic values: 1,961 and 1,864 respectively). Frequency and cover of species and floristic value of vegetation was recorded in two plots on each ditch, one along a sprayed and one an unsprayed edge of sugar beet (seven), potato (eight) and winter wheat (20) fields in June-July.

 

Leave headlands in fields unsprayed (conservation headlands) Farmland Conservation

A replicated, controlled, paired study in 1991-1992 of ditch banks on arable farms in the Netherlands (de Snoo & van der Poll 1999) found that plant diversity and the value of the vegetation in terms of species rarity was significantly higher on ditch banks along unsprayed edges of winter wheat (65 species, floristic value: 2201) than those sprayed with pesticides (50 species, floristic value: 1181). There was no significant difference on banks along unsprayed and sprayed edges of sugar beet (species: 48 and 41, floristic values: 3616 and 3029 respectively) and potato crops (species: 46 and 41, floristic values: 1961 and 1864 respectively). Frequency and cover of species and floristic value of vegetation (scoring system based on the importance of different plant species in terms of rarity) was recorded in two plots on each ditch, one along a sprayed and one an unsprayed edge of sugar beet (seven), potato (eight) and winter wheat (20) fields in June-July.
