Ecology and Silviculture of Trembling Aspen
Trembling aspen (Populus tremuloides Michx.) generally grows as clones in which stems, ranging from many thousands to only a few, are interconnected by a common root system. When clones are very large, in one recorded case involving about 47␣ 000 stems joined together over a 43 ha area, aspen becomes a candidate for earth’s most massive and oldest organism. Recent analyses suggest that aspen cl...
متن کاملThe Regeneration of Aspen Stands in Southern Utah
research conducted at Utah State University that identified factors to improve the success of regenerating aspen in southern Utah. Evaluating past si lvicultural regeneration treatments indicated that the presence of pre-harvest advance reproduction, site preparation by broadcast burning, and decreasing browsing pressure could increase the quantity of aspen regeneration. The outcomes are genera...
متن کاملThe Role of Postfire Coarse Woody Debris in Aspen Regeneration
The paucity of aspen (Populus tremuloides) regeneration in the western United States and on Yellowstone National Park’s (YNP) northern range has been of concern to managers and scientists for much of the 20th century, with the effects of ungulate browsing, climate fluctuation, and fire suppression being vigorously debated. We analyzed the interaction of fire and elk (Cervus elaphus) browsing in...
متن کاملRegenerating Boreal Mixedwoods : Three – year results of a Group Shelterwood Silviculture System in Trembling aspen – White spruce Stands
• Extension • Research • Consulting • PHOTO 1. Boreal mixedwood stand where both aspen and white spruce are within the dominant and co-dominant crown classes. Mixed species stands provide options for creating a wide variety of future stand conditions. Forest managers are increasingly being asked to consider and apply a diversity of silviculture systems to address the variety of social, economic...
متن کاملMultiaged Silviculture of Ponderosa Pine
Ponderosa pine (Pinus ponderosa P. & C. Lawson) is highly suitable for management using multiaged systems. This suitability is primarily the result of a frequent, low severity disturbance regime, but also because it naturally occurs at low densities and has a long history of management to promote multiple age classes. Several different stocking control tools are available for ponderosa pine inc...
