Book excerpt: One hundred thirty forests stands ranging in age from 1 month postfire to 200 years were sampled and described by successional series (white spruce and black spruce) and by developmental stage (newly burned, moss-herb, tall shrub-sapling, dense tree, hardwood, and spruce).

Download or read book Forest Ecosystems in the Alaskan Taiga written by K. van Cleve and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The information presented in this book is the result of combined research efforts of scientists at the University of Alaska, Fairbanks, the Institute of Northern Forestry, USDA Forest Service, and the Systems Ecology Research Group, San Diego State University. The objective of the volume is to present a synthetic overview of structure and function of taiga forest ecosystems in interior Alaska. The data base for this work has appeared in earlier published articles including the special issue of the Canadian Journal of Forest Research Volume 13:5 (1983). Stimulus for this book was a conference held in Fairbanks from June 10-14, 1983. The papers presented at the conference were fore runners of the chapters in this book. We invited 19 scientists from North America and England to critique our research and synthesis efforts. Six of these people were asked to write introductory chapters for each section of the book. Formal presentation sessions, combined with field trips to research sites, introduced the invitees to the primary and secondary successional ecosystems with which we were dealing. A major wildfire, only 24 km from the University campus, was contained the week prior to the conference and one field trip provided graphic evidence of fire impact in subarctic forests. The conference conveners regretted that it was not possible to host a similar meeting during synthesis efforts in mid-January.

Download or read book Vegetation Response to Prescribed Fire in the Kenai Mountains Alaska written by Tina V. Boucher and published by . This book was released on 2003 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 1977 and 1997, 4000 ha were burned to promote regeneration of tree and shrub species used for browse by moose (Alces alces) in the Kenai Mountains. Species composition was documented along burned and unburned transects at 17 prescribed burn sites. Relationships among initial vegetation composition, physical site characteristics, browse species abundance, and competitive herbaceous vegetation were examined to determine controls on browse species regeneration after prescribed burning. Browse species abundance after burning was inversely related to Calamagrostis canadensis Michx. Beauv. (bluejoint reedgrass) abundance prior to burning. Calamagrostis canadensis abundance was related to specific landscape characteristics. Depositional slopes, such as fluvial valley bottoms and toe slopes, often featured soils with deep, loamy surface horizons. Sites with these characteristics generally showed large increases in C. canadensis cover after prescribed burning, even when C. canadensis was a low percentage (3 percent) of the canopy cover prior to burning. The most important preburn variables for predicting postburn browse species abundance were preburn C. canadensis cover and the type of surficial deposit. Site conditions that are favorable to C. canadensis may be problematic for successful regeneration of browse species, especially if browse species are not present in the initial composition.

This book was released on 2008 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In interior Alaska black spruce forest succession and vegetation properties are tightly linked to fire disturbance, partly due to the functional properties of species. Climatically induced changes in the fire regime could negatively affect some functional groups and potentially lower the functional diversity of stands through changes in fire severity and site moisture. In addition, there is little information regarding the relationship between pre- and post-fire community composition in black spruce communities of interior Alaska. To contribute to our knowledge regarding post-fire plant community dynamics, I investigated how post-fire community properties in relation to fire severity and site moisture: 1) species composition, in which pre- and post- fire community composition was compared to determine changes in species richness and functional diversity and 2) the functional traits of species. Pre- fire species composition in black spruce forests was dominated by late successional understory species and was most similar in species composition to low severity burned sites (regardless of stand age). Site moisture did not appear to affect the change in species composition post-fire in the first two years following fire. Functional groups that showed significant changes post-fire were bryophytes, lichen and evergreen shrubs. When each species was deconstructed into a set of functional traits, I observed that these traits were tightly linked to fire severity. These results have large implications under projected climate scenarios that predict increasing fire extent and severity in the boreal forest because high severity fire changes the species composition and associated functional traits of black spruce post-fire communities in interior Alaska"--Leaf iii.

Book excerpt: Global warming is altering the fire regime of interior Alaska, which may have cascading effects on the prevalence of forest types and species dominance across this region. Our objective was to investigate the relationship between vegetation composition and fire in the boreal forest of interior Alaska. We utilized data from over 700 plots sampled across the landscape designated as the Tanana region by the US Forest Service for Forest Inventory Analysis (FIA), as well as fire history records. We compared biomass and stem density of conifer and hardwood forest types, as well as individual tree species, across a gradient of landscape topography (uplands vs lowlands, aspect, slope, elevation), time since fire, and number of fires. Hardwood biomass was greater than conifer biomass and black spruce has far greater stem density than all other tree species. Conifer biomass was more affected by upland or lowland position and time since fire than elevation, slope (except at slopes >25%) or aspect. Conifer density was only affected by time since fire, increasing after 50 years. Hardwoods were more variable than conifers; biomass was only driven by time since fire and stem density was only driven by upland or lowland position. Several conifer and deciduous species (black spruce, balsam poplar, quaking aspen) showed a decline in biomass at sites that burned twice since 1940 compared to sites that burned once. White spruce and paper birch did not show a decline in biomass, and tamarack showed a decline in stem density. Certain elevation ranges, especially 1000-2050, were more favorable for high biomass levels of species such as white spruce and paper birch. Our results suggest that upland or lowland position and time since fire are more important variables than slope or aspect for determining forest type and species composition in this ecosystem, and that elevation is a variable that creates spaces on the landscape that may be favorable to a limited number of species. As fire increases in frequency and extent in Alaska, this may have important consequences for vegetation composition, thus creating lasting impacts on the landscape of Alaska for the foreseeable future.
