This book was released on 2006 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The boreal forest covers 12 million km2 of the northern hemisphere and contains roughly 40% of the world's reactive soil carbon. The Northern high latitudes have experienced significant warming over the past century and there is a pressing need to characterize the response of the disturbance regime in the boreal forest to climatic change. The interior Alaskan boreal forest contains approximately 60 million burnable hectares and, relative to the other disturbance mechanisms that exist in Alaska, fire dominates at the landscape-scale. In order to assess the impact of forecast climate change on the structure and function of the Alaskan boreal forest, the interactions among climate, fire and vegetation need to be quantified. The results of this work demonstrate that monthly weather and teleconnection indices explain the majority of observed variability in annual area burned in Alaska from 1950-2003. Human impacts and fire-vegetation interactions likely account for a significant portion of the remaining variability. Analysis of stand age distributions indicate that anthropogenic disturbance in the early 1900's has left a distinct, yet localized impact. Additionally, we analyzed remotely sensed burn severity data to better understand interactions among fire, vegetation and topography. These results show a significant relationship between burn severity and vegetation type in flat landscapes but not in topographically complex landscapes, and collectively strengthen the argument that differential flammability of vegetation plays a significant role in fire-vegetation interactions. These results were used to calibrate a cellular automata model based on the current conceptual model of interactions among weather, fire and vegetation. The model generates spatially explicit maps of simulated stand ages at 1 km resolution across interior Alaska, and output was validated using observed stand age distributions. Analysis of simulation output suggests that significant temporal variability of both the mean and variance of the stand age distribution is an intrinsic property of the stand age distributions of the Alaskan boreal forest. As a consequence of this non-stationarity, we recommend that simulation based methods be used to analyze the impact of forecast climatic change on the structure and function of the Alaskan boreal forest"--Leaf iii.

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.

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). Patterns of change in the two successional series are described. In addition, 12 mature forest communities are described in quantitative and qualitative terms.

This book was released on 2017-10-28 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Predicting the Effect of Fire on Large-Scale Vegetation Patterns in North America Ecological considerations provide constraints on the vegetation transitions produced by these reductions of lai, and additional insight into successional dynamics and changes in species composition. For example, fire can cause changes in the domi nant plant phenology or leaf type in a biome without obligatory changes in lal. Under standing how ecological effects preset the initial conditions to which fire behavior models are applied will be a key step in integrating biotic and abiotic processes, to effectively model the mechanisms of change at the biome scale.

Download or read book The Effects of Fire Severity and Site Moisture on Species Composition and Functional Properties of Black Spruce Forests in Interior Alaska written by Emily Louise Bernhardt and published by . 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.
