Book excerpt: S2The Universities of Maine, Massachusetts, and New Hampshire, in cooperation with the Northeastern Forest Experiment Station, initiated in 1959-60 a study of the effects of site and stocking on the growth of eastern white pine. The primary purposes of the study were to develop equations for: (1) predicting the volume increment per acre of pure, even-aged, white pine stands from observable characteristics of the stand, soil, and topography; and (2) predicting the increment of individual white pine trees related to characteristics of the tree, stand, and site. By 1965, measurements of stand growth and development for a 3-year period were available from nearly all field plots. A preliminary analysis revealed that one or more additional remeasurements should be taken before a final summary of the periodic growth of trees and stands is made. Nevertheless, useful and accurate relationships were developed between stand yield, or volumes per acre, and stand age, site, and stocking; and this information is presented in this paper. Yield tables based on the plot data from New Hampshire, using stand height in place of age and site index, have been published by Barrett and Allen (1966).S3.

This book was released on 2013-06-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.
