Leave headlands in fields unsprayed (conservation headlands) Farmland Conservation

A continuation of the same replicated, controlled, paired study as in (Rands & Sotherton 1986) in Hampshire, UK, (Dover et al. 1990), found that butterfly (Lepidoptera) abundance was greater on conservation headlands than on conventional headlands over a further three years (1985-1987). Between 1984 and 1987, 29 species of butterfly were recorded, of which 13-21 were on conservation and 13-17 on conventional headlands each year. Significantly more individuals were found on conservation headlands (222-472/km) than on conventional headlands (80-259/km) in all years. This study was part of the same experimental set-up as (Rands et al. 1984, Rands 1985, Rands 1986, Rands & Sotherton 1986, Sotherton 1991, Dover 1997).
