Modeling Complex Forest Ecology in a Parallel Computing Infrastructure
Effective stewardship of forest ecosystems make it imperative to measure, monitor, and predict the dynamic changes of forest ecology. Measuring and monitoring provides us a picture of a forest's current state and the necessary data to formulate models for prediction. However, societal and natural …

KNOWLEDGE AND USE OF NATIVE TREES BY LOCAL FOREST USERS: IMPLICATIONS FOR A PHILIPPINE PROTECTED AREA
This thesis examines the forest knowledge of non-indigenous, local forest users in the Northwest Panay Protected Area located on the island of Panay in Central Philippines, and the opportunities and constraints to integrating this knowledge into local conservation efforts. The research is based on …

Heterogeneity of Stand Structure, Fuels, and Wildfire Hazard in Dry and Moist Old-Growth Ponderosa Pine Forests: Case Studies from Western Montana
… we analyzed two old-growth ponderosa pine forest restoration projects in western Montana with different moisture regimes. We utilized available fixed-area plot data to describe heterogeneity by analyzing the distributions of current and anticipated post-treatment plot conditions, and …

Forest dynamics at regional scales: predictive models constrained with inventory data
Forest ecosystems store more carbon than the atmosphere and harbour the majority of the world's biodiversity, yet their response to changing climate is uncertain. Forest simulation models make landscape-level predictions of forest dynamics by scaling from key tree-level processes, but models …

Terrestrial laser scanning to characterise three-dimensional foliage and woody material distributions in trees
… of foliage and wood distribution within forests is essential for understanding, managing and monitoring forest ecosystems. The recent advances in terrestrial laser scanning (TLS) technologies have provided new opportunities to measure the 3D structure of forest canopies, which in turn can …

Bird use of avocado farms and intact forest in the Dominican Republic
… an increase of avocado farms and a subsequent forest loss. We conducted point-count bird surveys to determine how avian species richness and diversity differ between avocado farms and intact forest, as well as how vegetation differences between farms and forests could impact bird use. We found …

Adaptive Silviculture in an urban floodplain forest: exploring functional traits and soil responses for climate ready forests
Floodplain forests within the Mississippi National River and Recreation Area (MNRRA) are experiencing numerous ecological challenges related to altered hydrology, land use changes, introduced species, and climate change. One of the most pressing concerns is the loss of the predominant canopy …
