Marsh tits are declining across the UK due to woodland management changes that reduce their preferred dense undergrowth habitat. Conservation management can directly improve individual marsh tit welfare.
Individual marsh tits in degraded woodland with insufficient undergrowth structure face reduced foraging opportunities, reduced nesting site availability, and greater predation risk from aerial predators. Woodland management that creates structural diversity through coppicing and ride widening directly improves the welfare of resident marsh tits by improving habitat quality.
