When they co-exist in the same habitat, brown trout compete with brook trout for resources. Lessons from the past Today things are much different. We have learned many lessons from the past. The way we go about managing and protecting Penn-sylvania's forests and waters has improved. Forestry practices have changed and many important habitat management methods have been learned over the years.

In most cases, forests are no longer clear-cut. Cutting rotations are ecologically based and managed more carefully. Timbered areas are replanted after trees are removed. Some mature trees are left standing to act as a seed stock for new trees. Vegetation buffers are left along streambanks and roads.
