Book Description
Mountain pine beetle-killed ponderosa pine trees in three stands of different stocking levels near Bear Mountain in the Black Hills National Forest were surveyed over a 5-year period to determine how long they persisted as unbroken snags. Rate of breakage varied during the first 5 years after MPB infestation: only one tree broke during the first 2 years in the three stands; breakage increased during the third year; the highest percentage of snags broke during the fourth year; and 10% to 14% broke in the fifth year. Cumulatively, snag breakage was 76%, 91%, and 95% in a GSL 80/90, GSL 100/110, and unmanaged stand, respectively. On average, 56% of the snags broke below 25 ft. The rate and height of breakage in mountain pine beetle-killed trees indicates that they are unlikely to persist as suitable snags for more than 5 to 10 years after infestation.

Book Description
The first study focused on the history of the Black Hills National Forest, its centrality to life in the region, and its preeminence within the National Forest System, Black Hills Forestry is a cultural history of the most commercialized national forest in the nation. One of the first forests actively managed by the federal government and the site of the first sale of federally owned timber to a private party, the Black Hills National Forest has served as a management model for all national forests. Its many uses, activities, and issues—recreation, timber, mining, grazing, tourism, First American cultural usage, and the intermingling of public and private lands—expose the ongoing tensions between private landowners and public land managers. Freeman shows how forest management in the Black Hills encapsulates the Forest Service's failures to keep up with changes in the public's view of forest values until compelled to do so by federal legislation and the courts. In addition, he explores how more recent events in the region like catastrophic wildfires and mountain pine beetle epidemics have provided forest managers with the chance to realign their efforts to create and maintain a biologically diverse forest that can better resist natural and human disturbances. This study of the Black Hills offers an excellent prism through which to view the history of the US Forest Service's land management policies. Foresters, land managers, and regional historians will find Black Hills Forestry a valuable resource.
