Forest Insects and Diseases
Forest insects and diseases can affect all aspects of the way we use our forest resource. A walk in the woods is not as enjoyable if you are surrounded by defoliated trees. Economic losses can result when valuable stands are weakened or killed. Forest Health is a section within the Forest Protection Division of the Department of Natural Resources. This section provides technical advice and management options to forest stakeholders who are attempting to deal with pest problems.
