MP754: A Literature Review of the Effects of Intensive Forestry on Forest Structure and Plant Community Composition at the Stand and Landscape Levels

The effects of intensive forest management on forest structure and plant community composition are not well documented, particularly with respect to the forests in the Northeast. This review presents a six-part synthesis of the literature. The first section considers the effects of intensive forestry practices within the context of naturally regenerated stands. The second section reviews the changes associated with the planting of conifers in softwood sites, as well as those previously occupied by hardwood and mixed-wood stands. The third examines the impacts of intensive management specifically on bryophytes and lichens. The fourth section discusses changes in dead organic matter components of the stand and the fifth with the impact on tree pests. The final section views the effects of intensive forestry from the landscape-scale perspective and is followed by summary and conclusions. While this paper provides a summary of scientific information, it does not recommend policy or propose how the forest should be managed.https://digitalcommons.library.umaine.edu/aes_miscpubs/1022/thumbnail.jp

MP764: Field Manual for Managing Eastern White Pine Health in New England

This manual provides basic information for identifying and evaluating important health problems of eastern white pine in New England. The health problems include: • White pine weevil • White pine blister rust • Caliciopsis canker • White pine bast scale • White pine needle damage • Red rot or Red-ring rot In addition to providing descriptions of symptoms, signs, and risk factors, recommendations for white pine silviculture are described for managing stands for low densities and crop trees.https://digitalcommons.library.umaine.edu/aes_miscpubs/1039/thumbnail.jp

The contribution of open extremity fractures to infection in multiply injured patients

We sought to determine whether a contaminated open fracture was a reliable component for calculating the Outcome Predictive Score in patients with multiple injuries. We studied 41 patients whose primary source of contamination was open extremity fractures. Only one of the 41 patients developed osteomyelitis. The rate of infection from an open fracture is minimal in the multiply injured patient. Inclusion of patients with open fractures in studies that assess the likelihood of infection and the value of anti-infective agents incorrectly identified patients for clinical trials and results in an overestimation of survival based on the Outcome Predictive Score. These findings suggest that open fractures should be excluded as an entry criterion in future clinical trials.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31658/1/0000592.pd
