Wildlife-friendly farming shown to benefit UK moths.

Wildlife-friendly farming schemes can help boost the abundance of many UK moth species.Large moths (macro-moths) play an important role as pollinators, but numbers have fallen in the UK by 28% since 1968. The situation is particularly bad in southern Britain, where numbers are down by 40%, with habitat loss thought to be behind the decline. The kinds of moths that benefited the most from the schemes were those commonly found on grassland, but there was a group of specialized chalk grassland moths that only benefited when the schemes were close to remnants of this rare habitat. Scientists from the University of Liverpool and Natural England assessed the impact of schemes which are creating grassland habitats on the edge of arable farming fields.The team surveyed macro-moths species on arable fields with and without wide grass margins, and on protected flower-rich chalk grasslands in southern England. The findings, which are published in the Journal of Applied Ecology, show that even small-scale habitat creation can benefit the moth population, with the abundance of grassland moths 40% higher on wide grass margins compared to margins outside schemes. Furthermore, moth species that are normally specialised to chalk grassland habitats also benefited from these schemes, provided that habitats were created close to existing chalk grassland. Agri-environment schemes provide funding to farmers and land managers to farm in a way that supports biodiversity, enhances the landscape, and improves the quality of water, air and soil.
