Here's an example of sustainable forestry as practiced by the Menominee Indians in Wisconsin.

When the Menominee Indian reservation was first established in Wisconsin, it contained an estimated 1.3 billion board feet of timber. (Board feet is a unit measuring the amount of wood which comes from a tree.)

From 1865 to 1989, the tribe harvested about 2.4 billion board feet of wood to sell. They used the money to sustain the tribe, and to replant and take care of areas of the forest.

Today there are approximately 1.7 billion board feet of timber contained within the reservation. Even after 135 years of harvesting, there are more trees there now than there were in 1865.
