Recreational use of forests I believe is closely connected with the standard of living, leisure time etc. What are the opportunities to develop lesson plans for different age group with this topic?
Here is some information on the Emergence of of Outdoor Recreation:
In the late 19th century, industrial development and urban growth transformed the US. With increasing numbers living in urban areas, the benefits associated with the natural environment achieved greater recognition. National publications highlighted the numerous outdoor sites and natural landscape available and promoted tourism for those desiring to escape city life.
By 1910, Forest Service began to give recreation greater priority. Between 1901 and 1910, a dramatic increase in Forest Service's landholdings occurred, many near large population centers. As a result city dwellers increasingly turned to nearby forests for recreation. Equally important the workers had more leisure time (because of reduced hours of work), the popularity of the automobile and increased road access and trails to forest areas were soon used as recreational roadways for fishing, hunting and camping.
