Informal social roles are not always easy to recognize, but can be identified with careful research. They are key indicators of a group's health and happiness. Within the family, one informal role is the family hero, the person who defines integrity and upholds family morality. Others are the family arbitrator, the person who keeps the peace, and the family historian, often a grandparent, who relays valuable cultural information that maintains both the family and the larger society. And finally, there is the family friend, the person who provides comfort and companionship to the family members with emotional needs.

Several men have been responsible for promoting forestry as a profession. Foremost was Gifford Pinchot, the father of the professional forestry in America. He was chief of the Forest Service from 1898 until 1910, working with President Theodore Roosevelt to instigate sound conservation practices in forests. Later he was professor of forestry and founder of the Pinchot School of Forestry at Yale University. Another great forester was Dr. Bernard E. Fernow, the first head of the U.S. Forest Service. He organized the first American school of professional forestry at Cornell University.

The foresters of today, like Pinchot and Fernow in the past, plan and supervise the growth, protection, and utilization of trees. They make maps of forest areas, estimate the amount of standing timber and future growth, and manage timber sales. They also protect the trees from fire, harmful insects, and disease. Some foresters may be responsible for other duties, ranging from wildlife protection and watershed management to the development and supervision of camps, parks, and grazing lands. Others do research, provide information to forest owners and to the general public, and teach in colleges and universities.
