He is a plant pathologist from Colorado who works for the USDA Forest Service in Forest Health Protection. While James J. Worral was and Associate Professor of Environmental and Forest Biology at the College of Environmental Science and Forestry, he began compiling the lecture notes that would one day turn into this tree pathology textbook and website.
By putting his textbook online, Worral has been able to incorporate some web technologies into his text that make it even more useful for students. Key terms are written in purple. Readers can simply hover over the term to see a definition. I so wish more of the textbook authors would do this instead of having people click back and forth to a glossary page. Illustrations abound within the text.
Site also includes a calendar of forestry-related events.
