The Value of Forests Commercial Forests are forested areas that can be harvested profitably. -conditions tend to be relatively warm with significant amounts of rain -tend to be near roadways, railways, or waterways. Non-Commercial Forests are forested areas that are unlikely to be harvested because of poor profit projections. -temperature and precipitation levels are relatively low (poor conditions for growing) -tend to be located at too great a distance from roads, railways, and waterways to be of economical importance.
