Mark fences to reduce bird collision mortality
In a randomised, replicated and controlled study at thirteen sites in the Scottish Highlands from April 1995 to May 1997 (Baines & Andrew 2003), significantly fewer birds collided with sections of deer fence marked with orange netting (0.35 collisions/km/month) than with unmarked control sections (1.13 collisions/km/month). A total of 437 birds collided with the fences, 92% of which were gamebirds (red grouse Lagopus lagopus scoticus accounted for 42%, black grouse Tetrao tetrix 29% and western capercaillie Tetrao urogallus 20%). Collision rates in marked sections were 91% lower for black grouse and 64% lower for capercallie than in control sections. A total of 20 km of ten different fences was tested, with two 1 km stretches of each fence being randomly assigned to treatments.
