Thanks Julian,

I agree with much of what you are suggesting, however it does not answer my
query regarding whether trees with H. annosum should be retained
particularly in a woodland setting? Surely this goes against best practice.
No?

Dear Collette


Best practice relates to all aspects of forest management, including risk management:

Leaving cut stumps exposed as possible source of inoculum is generally considered unnecessary risk exposure for future crops and so, bad practice in commercial plantations.

Leaving habitat trees standing, as possible source of inoculum in multi-purpose forests, may be justifiable risk exposure.

Sanitation policies tend to be more global than local; i.e. directed at the multiple stumps of clear fell coups, rather than the status of 1-2 trees in all but the most valuable plantations.

The risk may be reduced by continuing to treat exposed stumps of felled trees, and you might consider cordon felling of valuable timber trees around the habitat trees.

However, you would need to do this under advice to minimise windthrow risk and changes to the ecology of the habitat.

Regards

Adam
