Bullish On Forestry Careers, Steven H. Bullard, Thomas J. Straka

Faculty Publications

During the next decade, baby boomer-aged foresters, those born from 1946 to 1964, will be retiring in large numbers. This retirement trend is true for all sectors of forestry employment, from state and federal agencies to private firms and industries.

Forestry employers in both public and private sectors are clamoring for more graduates, as well as for more diverse graduates, from forestry degree programs. With looming retirements and industry growth, employers can project the number of positions opening, and they are aware that U.S. forestry schools are not producing sufficient graduates to fill the positions.

Sub-Pixel Classification Of Forest Cover Types In East Texas, Joey Westbrook, I-Kuai Hung, Daniel Unger, Yanli Zhang May 2012

Sub-Pixel Classification Of Forest Cover Types In East Texas, Joey Westbrook, I-Kuai Hung, Daniel Unger, Yanli Zhang

Faculty Publications

Sub-pixel classification is the extraction of information about the proportion of individual materials of interest within a pixel. Landcover classification at the sub-pixel scale provides more discrimination than traditional per-pixel multispectral classifiers for pixels where the material of interest is mixed with other materials. It allows for the un-mixing of pixels to show the proportion of each material of interest. The materials of interest for this study are pine, hardwood, mixed forest and non-forest. The goal of this project was to perform a sub-pixel classification, which allows a pixel to have multiple labels, and compare the result to a traditional ...

Synthesis Of Knowledge Of Extreme Fire Behavior: Volume I For Fire Managers, Paul Werth, Brian Potter, Craig Clements, Mark Finney, Scott Goodrick, Martin Alexander, Miguel Cruz, Jason Forthofer, Sara Mcallister

Faculty Publications

The National Wildfire Coordinating Group definition of extreme fire behavior (EFB) indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/ spotting, presence of fire whirls, and strong convection column. Predictability is difficult because such fires often exercise some degree of influence on their environment and behave erratically, sometimes dangerously. Alternate terms include “blow up” and “fire storm.” Fire managers examining fires over the last 100 years have come to understand many of the factors necessary for EFB development. This ...
