Forest Ecology Objective: Describe forest ecololgy and idenfity characteristics of a healthy forest. By: Mrs. Jacie Pressett

What is ecology? Eco = house ology = study of Study of nature’s “house” or environment and the interactions within.

“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

Healthy Forests Healthy Forests Are allowed to age and succession occurs within the natural cycle. Have plentiful native species Are harvested sustainably

Unhealthy Forests May be affected by: Non-native species Erosion, due to human activities Watershed Damage Fire Suppression

Forest Management Techniques Forest Management Techniques vary depending on goals for the specific area. 400 ac. Wood Activity

Objective: Describe the growth and decline of a forest.

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.

What stage of succession is in the foreground?

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.
