PA Forests and Old Growth Forests

Before class, get started on… Take out your Field Study Lab and turn it in up front. Take out your notes and answer the following questions… What is an old growth forest? Where is the area of the largest old growth forest in the country?

Old Growth Forest Old-Growth Forests (virgin forest): forests that have never been disturbed (logged or burned)

California Redwoods

PA Forest History 29 million acres of virgin forest in the time of the colonists 200 years ago logging was done to clear the land for crops A high demand for wood made PA the leading lumber producer in the nation in the 1860’s

PA Forest History Con’t Many of the hemlock trees (state tree) were cut down for the tannic acid in their bark and the wood was wasted By the 1900’s almost all the virgin forests were removed Today Pa manages 2 million acres of forest and only a few patches of virgin forest

Old Growth Forest in the Pacific Northwest Largest area of old-growth forest in the country. The area is high in biodiversity.

Old Growth Forests can be sold Law requires that national forests and other federal lands to be managed for multiple use: Logging Mining Grazing Recreation Fish and Wildlife Habitat Watershed Protection

Protected forests Only National Parks or Wilderness Areas are protected from logging

Conflict Between Logging and Environmental Protection…
