A new index for describing the structural complexity of forests

Creator:: Zenner, Eric K.
Abstract:: Despite the critical ecological roles of structural features in forests, ecologically relevant quantitative measures of structure that allow comparisons among forest stands are still limited. A new index, the structural complexity index (SCI), was developed to characterize and compare the structural complexity of different forests. Point patterns of stem-mapped trees...

Forest structure, species diversity and spatial patterns of trees in monodominant and mixed stands in the Ituri Forest, Democratic Republic of Congo

Creator:: Makana, Jean-Remy M.
Abstract:: Two rectangular 10-ha plots (200 x 500 m) were established in each of the two main forest types of the Ituri Forest, Democratic Republic of Congo (formerly Zaire). The description of stand structure and species diversity, the comparison of the two forest types, and the evaluation of the effects of...

Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Dead fuels and understory vegetation six years after a large mixed-severity wildfire in southwest Oregon

Creator:: Nathanson, Amy
Abstract:: Though the mixed-evergreen forests of the Klamath Siskiyous have a long history of large, mixed-severity fires, most research in this region has concentrated on the impacts of high-severity fire. Knowledge of the ecological effects of low- and moderate-severity areas within mixed-severity fires is important because such areas may account for...

The Impact of Disturbance on Carbon Stores and Dynamics in Forests of Coastal Alaska

Creator:: Yatskov, Mikhail A.
Abstract:: Changes in climate caused by increased concentrations of carbon dioxide (CO₂) in the Earth’s atmosphere have led land and ocean surface temperatures to increase by 0.85°C and sea level to increase by 19 cm relative to preindustrial times. Global climate change will lead to further alterations in mean temperature and...

Forest vegetation and fuel dynamics following stand-replacing wildfire, re-burn, and postfire management in the Siskiyou Mountains, Oregon

Creator:: Donato, Daniel C.
Abstract:: Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...

Using oral histories to document changing forest cover patterns : Soap Creek Valley, Oregon, 1500-1999

Creator:: Zybach, Bob
Abstract:: This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...

Contemporary regional forest dynamics in the Pacific Northwest

Creator:: Reilly, Matthew J. (Matthew Justin), 1975-
Abstract:: Recent climatic warming trends and increases in the frequency and extent of wildfires have prompted much concern regarding the potential for rapid change in the structure and function of forested ecosystems around the world. Episodes of mortality in wildfires and insect outbreaks associated with drought have affected large areas and...
