An agreement with the landowner was still being negotiated, and the authority sought confirmation of 30 years of management. The dossier assessed residual effects on protected species as not significant, but the authority considered that assessment inadequate for several groups given the two-year works and called for compensation and an updated protected-species derogation dossier.
