Just like a group of houses don’t equate a city, a group of trees doesn’t equal a forest. A forest includes trees and all other plants and animals that interact to create the forest system. A forest is a balanced ecosystem in which trees and plants photosynthesize to generate food that is used by themselves and animals. Decaying plants and animals release nutrients that are taken up again by the plants.
Forests were a formidable barrier to European settlers in America. Forests had to be cleared to create room for crops.
Commercial forests are forests that have the potential to be economically productive. This doesn’t mean that the forest is being used this way. Much of the commercial forestland is in small parcels near homes or parks. Noncommercial forest might be on very rough terrain or on swampy land or be part of a park or preservation area. Much of the forestland of today is being taken over for urban and industrial development.
The terms softwood and hardwood have little bearing on the actual hardness of the wood!
