“The forestlands of the United States tell a fascinating story about humankind and its relationship with the land. It is a story of trial and error, of consumption and conservation, … But most of all, it is a story of regrowth, renewal, and abundance.” -- Society of American Foresters

History of Forest Ecology
Early U.S. Forest Management focused on lumber harvests and was reflective of the attitude that the new world’s resources were infinite. Prior to European settlement, the United States was 46 percent forested. Much was harvested for housing, industry, the creation of railroads and to clear land for farming.

History of Forest Ecology
Awareness of the need for conservation began emerging in early 1800’s and eventually lead the the Environmental Movement of the 1960’s and 1970’s

Old USFS Values vs. Current Values
1989 Chief’s New Perspectives Initiative – Streses Ecosystem Management instead of singly timber management. Forest Service Mission: Sustain the health, diversity, and productivity of the Nation's forests and grasslands to meet the needs of present and future generations
8
Healthy Forests Healthy Forests
Are allowed to age and succession occurs within the natural cycle. Have plentiful native species Are harvested sustainably
9
Unhealthy Forests May be affected by:
Non-native species Erosion, due to human activities Watershed Damage Fire Suppression
10
Forest Management Techniques
Forest Management Techniques vary depending on goals for the specific area. 400 ac. Wood Activity
11
Objective: Describe the growth and decline of a forest.
12
Succession Forests have a lifecycle.
Begin with mosses and lichens, then grasses and forbs, then shrubs, finally conifers. When forest communities reach their climax age a natural disturbance will reset the cycle and cause succession.
13
What stage of succession is in the foreground?
15
Objective: Explain the role of fire in forest management.

Maniti LaSal forest is heavily covered in large and old pine species
Maniti LaSal forest is heavily covered in large and old pine species. A Beetle kill devastated the area. Fire started from a lighting strike killed all vegetation, but growth has started anew. A healthy forest ecosystem is rising from the ashes.
