Deletes the provision excluding sawmill operations from the activities included in a forestry operation. Provides that in a civil action in which an agricultural or forestry operation is alleged to be a nuisance, the prevailing defendant recovers the costs and expenses determined by the court to have been reasonably incurred in the defense of the action, including attorneys' fees.

Applies to causes of action arising on or after July 1, 2013.
