Forest futures
… must also return to its source - the forest - for inspiration and sites of intervention. This thesis sites itself within Mendocino National Forest in northern California. As sites of both extraction and conservation, National Forests are messy landscapes often overlooked in favor of …

Forest Framing
… with local knowledge and tools to restore forest ecology and boost rural economies. The proposal is situated in the context of Sweet Home, Oregon, a former logging community. Like many small towns across the United States, Sweet Home is in a state of social and ecological crisis, combating …

Monitoring the Knysna forest : species, community and forest responses
Forests are valuable ecosystems to society but are greatly threatened by changing factors from habitat conversion to climate change. South Africa's only extent of indigenous forest is predicted to disappear within the next 30 years. Many challenges are currently faced when trying to detect and …

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.
… thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was …

Full Forest Treebanking
In this thesis, I present a new method of producing treebanks using constraint-based grammars. Rather than requiring an explicitly enumerated set of candidate analyses per utterance, my method works from an implicit representation, allowing the annotator to efficiently select the correct analysis …

Building resilience in forest-dependent communities through sustainable forest bioeconomy development
… to determine the characteristics of a future forest bioeconomy that will contribute to the resilience of forestry communities across northeastern Ontario to inform bioeconomy development in the region. A regional approach is taken to evaluate pathways for forest bioeconomy development over the …

Climate change adaptation and sustainable forest management in the boreal forest
Climate change will pose increasing challenges to forest managers working to achieve sustainable forest management in the boreal forest. A logical starting point for climate change adaptation is to proactively identify management practices and policies that have a higher likelihood of achieving …

Modeling forest protection values for the southern Appalachian spruce-fir forest
… value for southern Appalachian spruce-fir forest protection may be sensitive to changes in the forest's physical condition. Further, different recreation groups may hold significantly dissimilar values for forest protection. Household and recreation group willingness to pay for southern …

The correlation between available deer browse, forest cover type, and forest site
… phase of a ten-year project designed to evaluate forest-wildlife relationships. The project was initiated in 1958 on the Jefferson National Forest, Broad Run Wildlife Management Area, Craig County, Virginia. The objective of the study was to determine if correlations existed between quantities of …

Spatiotemporal Informatics for Sustainable Forest Production Utilizing Forest Inventory and Remotely Sensed Data
… for assessing the status and trends of forests, trees, their products, and their services. Techniques for using readily available data such as the Forest Inventory and Analysis (FIA) database and output from forest disturbance detection algorithms derived from Landsat data, such as …

Spatio-temporal patterns of forest disturbance in western North America: implications for forest resilience
Globally, forest disturbance activity is changing in response to changing climate. As disturbance regimes change, concerns have been raised that the mechanisms of forest resilience (i.e., the capacity of forests to tolerate disturbance) may begin to break down. To successfully monitor, forecast, …

Acid deposition effects on soil chemistry and forest growth on the Monongahela National Forest
… fuels, and has been found to negatively impact forest ecosystems. AD may acidify soils through base cation leaching or Al mobilization, may cause accumulation of nitrates and sulfates in soils, and in some cases has been related to forest decline. The Monongahela National Forest (MNF) lies …

The Role of Fire in Montane Forest Environments in the Willamette National Forest, Oregon
… Blair Lake watershed in the Willamette National Forest of Oregon. The record shows that during the late glacial period, overall fire frequency was relatively low. <em>Pinus </em>and <em>Abies </em>were the dominant vegetation, along with <em>Pseudotsuga </em>and <em>Alnus</em>, suggesting that an …

Floristic and dynamics of Sand Forest, a subtropical dry forest type in South Africa
Unlike most dry forests, Sand Forest has been largely untransformed by human activity until very recently, and provides a rare opportunity to investigate the dynamics of old-growth dry forests. Twinspan classification and DCA ordination (Detrended Correspondence Analysis, an indirect gradient …
