Use organic farming instead of conventional farming Bat Conservation

A replicated, paired sites study in 2003 on eight paired farms near Bristol, UK (Pocock & Jennings 2008) found that organic cereal fields had similar common pipistrelle Pipistrellus pipistrellus activity to nearby conventionally farmed fields. Common pipistrelle activity did not differ significantly between organic cereal fields (total 96 bat passes) and nearby conventionally farmed fields (total 152 bat passes). Pairs of fields were matched to control for habitat variables and were sampled simultaneously during one night in May–August 2003. At each of 16 sites, bat detectors recorded bat activity from 45 minutes after sunset for 20 minutes at each of four points along a transect (two points within fields, two along field boundaries).
