The objective of the GSMAP is to manage grey squirrel populations in order to reduce their impact on red squirrel populations and on woodland ecosystems and their associated services. The GSMAP sets out actions that can be delivered through a partnership approach between the public, private and voluntary sectors to encourage and assist in grey squirrel population management. It doesnotpropose a pan-Wales cull or the eradication of grey squirrel from Wales.
