In the Acadian Forest Region of northeastern North America, forest managers are under increasing public pressure to restore the forest to a more historic, natural condition by reducing in clearcutting and promoting partial-cut treatments that more closely emulate historic, local natural disturbance regimes.
However, although numerous studies on the effects of partial-cutting on forest Cited by: 3.

PCT has been shown to be effective for reducing stand density, accelerating crop tree growth, enhancing understory structural development and maintaining desired species composition of northern conifer stands. The year research program studied the impacts of pre-commercial thinning (PCT) and fertilization on tree growth, plant diversity, forage production, and ungulate habitat use.
Ecological effects of cattle grazing were also studied. Three study areas were located in south-central British Columbia, Canada.
Each study area was comprised of densely stocked stands of young lodgepole pine (Pinus Cited by: 1. Full text of "Research for tomorrow's forests: research accomplishments. --" See other formats.

In therefore the value of bark harvested from species forest systems where artifcial regeneration is practiced, such as tulip poplar (Liriodendron tulipifera L.). planting density and competition control methods can When thinned hardwood stems are of precommercial infuence understory structure and composition (Curtis diameter, they may be used.
Height models for juvenile even aged mixed-species stands were developed for locations near Nelson, British Columbia. Separate models were developed for each conifer species found, as well as for paper birch (Betula papyrifera).
The objectives were to develop models for: 1) the number of years to reach breast height; 2) height achieved at a given age above breast height (height yield); 3. Dec 01, · Precommercial crop-tree release increases diameter growth of Appalachian hardwood saplings.

The Northern Hardwood Region, the Southern Pine–Hardwood Region, the Forest–Prairie Transition and the western edge of the Appalachian Mountains bound the Central Hardwood Region.
The Central Hardwood Region extends miles from southwest to northeast and covers approximately million acres; about half the region is forested. This book does not address all natural disturbances or all important ecological effects; for example, we do not discuss the effects of disturbances on nutrient cycling processes.
However, we hope the book does provide a guide or blueprint for a different, more interdisciplinary, approach to plant disturbance ecology. 12 DISTURBANCE AND SUCCESSION. Free essys, homework help, flashcards, research papers, book report, term papers, history, science, politics.
The effect of thinning and/or fertilizing a year-old, stagnated kon stand were studied on the island of Maui. In this precommercial thinning, the number of stems was reduced 50 percent.
Basal area growth rates for a 3-year period indicated that thinning increased growth significantly. In contrast, soil K, Ca, and Mg concentrations increased on both sites during 5 years of tree growth (Table 2).
Potassium increases were similar for the upland and bottomland, respec- tively, as ppm and ppm. Soil calcium increases were more variable between sites at ppm and ppm for the upland and bottomland, respectively. As a result, tree diameter growth is increased and the time required for the forest to reach harvestable size is decreased (17).
