Our forests are exposed to destruction by many enemies, the worst of which is fire. From 8,000,000 to 12,000,000 acres of forest lands annually are burned over by destructive fires. These fires are started in many different ways. They may be caused by sparks or hot ashes from a locomotive. Lightning strikes in many forests every summer, particularly those of the Western States, and ignites many trees. In the South people sometimes set fires in order to improve the grazing. Settlers and farmers who are clearing land often start big brush fires that get out of their control.
Old-time New England foresters coined the term “wolf tree” for trees they saw as having the ability to “eat” the sun and nutrients and prevent the growth of other trees. Today, however, we understand how wolf trees benefit wildlife. Join Aurora and Orion as they search for a wolf tree in the 3500-acre forest managed by Harvard University near Petersham, Massachusetts, looking for such clues as a large trunk, low branches, wildlife activity, and nearby smaller trees.
This multidisciplinary book covers all aspects of planning, designing, establishing and managing forests and trees and forests in and near urban areas, with chapters by experts in forestry, horticulture, landscape ecology, landscape architecture and even plant pathology. Beginning with historical and conceptual basics, the coverage includes policy, design, implementation and management of forestry for urban populations.
