asked the Secretary of State for Scotland what estimates the Forestry Commission has made or plans to make, of (a) crown thinning, (b) pollution damage, (c) symptoms of decline and (d) other diseases, in yew trees, in the United Kingdom and abroad.

The Forestry commission has no plans for a systematic survey of the state of health of this species. The Commission's research division investigates reports of damage and disease in yew in the same way as it does for other tree species.
