Examining the spatial relationship between pheasant (Phasianus colchicus) release pens and grey partridge (Perdix perdix) population parameters.

摘要

As UK grey partridge (Perdix perdix) numbers declined over the last half century, shooting estates changed the emphasis of game management, from wild grey partridges to reared released pheasants (Phasianas colchicus). A recent theory suggested that parasites carried by reared released pheasants may be partially responsible for the decline in the numbers of grey partridges. We used long-running monitoring data from two sites in lowland England to look for relationships between proximity to pheasant release pens and grey partridge population parameters
