Trees start from seeds grown in seedbeds, sometimes in a special glass house called a greenhouse. Some trees and shrubs are grown from cuttings. Cuttings are small pieces of a branch from a tree or shrub that are used to grow new trees and shrubs. Many people have jobs in the timber industry. They harvest trees to make wood products and paper.
People then plant new trees to take the place of the ones that they cut down.
It is important that the people in the timber industry are careful because it takes good management to grow trees as a renewable resource. Invite a forestry related professional to visit the class and make a presentation on the nature of his or her job. After discussing different types of jobs in the forest, ask students to think about what their favorite forest job would be. Discuss some of the specialized scientists that work in the woods - biologists, zoologists, herpetologists, etc. Forest rangers teach people how to protect the forest.
