Book excerpt: Summary tables are presented for aboveground biomass and nutrient concentrations for 20 aspen trees (Populus tremuloides Michx.) that were sampled at two study sites in Utah and Wyoming. Trees were divided into seven components - leaves, current twigs, old twigs, deadwood (branches), branches, bark, and bole wood. Samples from each component were analyzed for nitrogen, phosphorus, potassium, calcium, sodium, magnesium, zinc, iron, and percent ash.

Season of burning and preburn and posthum parameters were used as independent variables and posthum number of suck ers as the dependent variable. The preburn inde pendent variables consisted of the number, age, height, and diameter of suckers before burning; elevation, incident solar radiation (frank and Lee and mean diameter of old trees. The posthum independent variables were the number of new suckers the first fall following burning and the number of year-old suckers the second growing sea son after burning. Dependent variables were the number of year-old suckers present the second fall following burning and the number of' old suckers present the sixth year following burning. Regres sion analyses were performed to determine the best fitting relationships that were also judged to be bio logically reasonable.

Analytical data on the chemical composition of the three woods are recorded in table 1 and will be considered briefly as a means of comparing aspen with the other two woods, also indigenous to the Lake States. So far as the analytical values are concerned, quaking aspen compares favorably with yellow birch and sugar maple.

This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aspen is a key resource in the Rocky Mountain Region for wildlife forage and habitat, lumber products, scenery, and plays important roles in fire ecology and hydrological processes. There is evidence of aspen decline over much of the Intermountain West for approximately 100 years. In Dixie and Fishlake National Forests, UT, aspen distribution has decreased by nearly half. Causes of this decline are not well understood, although wildlife browsing by ungulates has been implicated as playing a major role. The objective of this research was to examine what soil or plant factors might be involved in wildlife browse choice in aspen. Twenty-two pairs of moderately and intensively browsed sites were studied to identify factors related to browse preferences over two field seasons. In the summer of 2008, sites were sampled in June, July, and August, and in the summer of 2009 sites were sampled in August only. Soils were analyzed for pH, EC, total nitrogen and carbon, and mineral nutrients. Leaf tissue samples were analyzed for defense chemical (tannin and phenolic glycoside) concentrations, mineral nutrients (via acid digestion) , acid-detergent fiber, water content, carbon:nitrogen ratio, and non-structural carbohydrate (sugar) concentration. No significant difference in phenolic glycoside concentrations between moderately and intensively browsed sites were found. Tannins were highest in sites with intensive levels of browsing. Iron was significantly higher and zinc lower in intensively than moderately browsed sites. Leaf moisture was also significantly lower in intensively browsed sites. In the absence of difference in phenolic glycosides, ungulates may be selecting browse sites based on iron requirements. Seasonal changes in the studied factors could be identified in 2008. Over the course of the summer, we found significant decreases in nitrogen, phosphorus, potassium, sulfur, zinc, iron, copper, phenolic glycosides, and moisture concentration. Seasonal increases in calcium, sodium, tannins, sugars, acid-detergent fiber, and carbon:nitrogen ratios were observed. The need for large ungulates to obtain specific nutrients may indicate that aspen is in higher demand as a forage at different times of the year, particularly in areas with forages low in these nutrients. Our data suggest that aspen high in iron may be at risk since other factors explaining browsing choice were not significantly different in our study. This information can help identify clones that are at risk and direct resources where and when they are needed most.

Book excerpt: Excerpt from Variation Among Healthy and Deteriorating Aspen Clones Previously, Schier (1975) described the general pattern of deterioration in western aspen (populus tremuloides Poorly stocked deteriorating clones were found growing adjacent to well-stocked mature healthy clones. The occurrence of deteriorating and healthy clones on similar sites indicated that the age at which aspen ramets begin to die is genetically controlled. It was noted that deteriorating clones were visually distinguishable from healthy ones. Their stems tended to be shorter and branchier, and to have poorer form than the stems of healthy clones. Thus it appeared that the longevity of aspen ramets was correlated with various morphological characteristics.

Book excerpt: Excerpt from Logging Methods and Peeling of Aspen Since most aspen stands have become established as the result of fires following logging, they are found on all types of soils and topography from level swamps to rugged morainic formations. In Minnesota the best stands are found on islands in.swamp areas and on lake-washed, till-clay formations These areas are relatively level except where past glacial streams have cut deep valleys, as is the case in the southeastern portion of Carlton County. In general, the aspen stands of the Lake States occur on terrain which does not present any difficult or peculiar logging problems different from those of other species in the area.

Sometimes these enemies were actually considered blessings in disguise. Now, however, that aspen not only is the most abundant but also one of the most widely utilized tree Species in the Lake States, there is increasing interest in anything that may affect its future supply.

Available in PDF, EPUB and Kindle. Book excerpt: The Aspen FACE experiment, located at the US Forest Service Harshaw Research Facility in Oneida County, Wisconsin, exposes the intact canopies of model trembling aspen forests to increased concentrations of atmospheric CO2 and O3. The first full year of treatments was 1998 and final year of elevated CO2 and O3 treatments is scheduled for 2009. This proposal is to conduct an intensive, analytical harvest of the above-ground parts of 24 trees from each of the 12, 30 m diameter treatment plots (total of 288 trees) during June, July & August 2009. This above-ground harvest will be carefully coordinated with the below-ground harvest proposed by D.F. Karnosky et al. (2008 proposal to DOE). We propose to dissect harvested trees according to annual height growth increment and organ (main stem, branch orders, and leaves) for calculation of above-ground biomass production and allometric comparisons among aspen clones, species, and treatments. Additionally, we will collect fine root samples for DNA fingerprinting to quantify biomass production of individual aspen clones. This work will produce a thorough characterization of above-ground tree and stand growth and allocation above ground, and, in conjunction with the below ground harvest, total tree and stand biomass production, allocation, and allometry.

Available in PDF, EPUB and Kindle. Book excerpt: Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.
