How deer fencing affects deer welfare and what design choices minimise injury, entanglement, and barrier effects on deer populations.
Deer fencing represents a case where a legitimate land management tool, used without adequate welfare consideration in its design, causes preventable suffering to the animals it is meant to exclude. Deer entanglement in fencing is a painful and often fatal welfare event that may not be discovered for days after it occurs. Good fence design — appropriate height for the target species, mesh size that prevents hoof entry, avoidance of features that funnel deer into fence corners — can substantially reduce entanglement risk without compromising the fencing's protective function. The welfare cost of poor fence design falls entirely on the deer, who have no choice in the matter.
