Merlin Upland Moorland Welfare and Population Recovery

The merlin is Britain's smallest raptor and a moorland specialist whose welfare is closely linked to heather management, prey availability, and persecution pressure.

Key Facts

UK merlin population is estimated at around 1,300 breeding pairs and is listed as a Schedule 1 species
Males hunt meadow pipits and skylarks over open moorland while females incubate
Heather burning rotation management maintains short heather for hunting and longer growth for nesting
Persecution on some grouse moors continues despite legal protection
Climate change is drying moorland habitats affecting prey availability and chick survival

Welfare Considerations

Merlins on managed moorland must navigate landscapes shaped by grouse moor management, which can simultaneously support and threaten their welfare. Short heather provides good hunting conditions but persecution pressure in some areas causes significant mortality. Breeding females incubating in long heather experience vulnerability to predation. Climate-driven changes in moorland hydrology are reducing the prey base available during the critical chick-rearing period, causing increased energetic stress in affected pairs.

What You Can Do

Report suspected merlin persecution to police wildlife crime units and RSPB Investigations
Support moorland management schemes maintaining diverse heather age structure
Participate in upland bird monitoring through BTO and RSPB survey programmes
Advocate for licensing of driven grouse shooting to include raptor protection requirements
Support research into merlin habitat requirements and climate vulnerability
