Wild Pine Marten: Recovery, Prey Welfare and Red Squirrel Benefit

Pine marten recovery in Scotland and England creates ecological cascades with complex welfare implications for multiple species.

Key Facts

UK pine marten population is concentrated in Scotland with reintroduction underway in England
Pine martens suppress grey squirrel populations through predation, benefiting red squirrels
Pine martens prey on a range of species and cause predation welfare costs to their prey
Marten reintroduction to Wales from Scotland has established successfully within a decade

Welfare Considerations

Individual prey animals killed by pine martens experience acute predation stress. However, the ecological cascade through grey squirrel suppression reduces squirrelpox-driven red squirrel suffering at population scale. Ecosystem welfare analysis must consider both predator and prey welfare impacts.
