Pine martens are being reintroduced to England and Wales after local extinction, raising important welfare questions about translocation.
Translocation for reintroduction involves capturing wild animals which causes acute stress. Transport to new areas and release into unfamiliar territory adds further welfare costs. Newly released animals may face hostile resident wildlife or insufficient prey. Monitoring protocols require repeated trapping that accumulates welfare impact. The welfare cost of translocation must be weighed against conservation benefits.
