An Evaluation of Long Grass as a Bird Deterrent on British Airfields
Preview not available

Abstract

Regular observations on thirteen airfields showed that birds were fewer and occurred less frequently on long grass (15-20 cm) than on short grass (5-10 cm) areas. This happened with the more hazardous species on British airfields viz, lapwing, woodpigeon, rook and starling and especially gulls. Other species were also scarcer in long grass, except for kestrels and pipits on three airfields and nesting terns on one coastal airfield. On two airfields where a good stand of long grass could not be grown on the experimental areas the bird numbers were the same as on short grass. The growing of long grass does not eliminate birds but generally reduces numbers and is therefore an effective component of bird control measures on airfields.
