Advanced red squirrel conservation welfare addresses the specific challenges of maintaining isolated island and peninsula populations.
Red squirrel welfare in isolated populations requires active management that continental populations achieve naturally through movement. Without grey squirrel management, disease and competition cause welfare costs for individual red squirrels including starvation, squirrelpox disease, and territorial displacement. Each grey squirrel management programme protecting a red squirrel population is preventing ongoing welfare costs for individual red squirrels whose survival depends on that protection.
