9:45 – 10:30    
How Decay Fungi Attack and Degrade Wood
Dr. Les Werner, Professor, University of Wisconsin-Stevens Point
White, brown, soft, sapwood, heartwood, root, basal, and all the rots in-between. Learn the different ways wood decay fungi preferentially attack wood components and structures.

12:45 – 1:30     
Basic Wood Decay Fungi Biology and Fundamentals of Decay Identification
Dr. Jason Smith, Associate Professor, University of Florida
Learn about wood decay growth and development in trees and the reproductive structures used to identify fungal species.

1:30 – 2:30     
Common Wood Decay Fungi of Florida Trees and Palms
Andrew Loyd, University of Florida and Bartlett Tree Research
Learn how to identify the common decay fungi that inhabit Florida’s woody vegetation and how each species attacks its preferred hosts.    

2:30 – 2:45    Break (divide into two groups for hands-on lab sessions)

2:45 – 4:30    
Wood Decay Hands-On Wood Lab, Afternoon Lab

Andrew got his BS degree from Louisiana State University and his Master of Scence degree from N. Carolina State University.

   Dr. Jason Smith
Dr. Jason Smith is assistant professor of forest pathology in the School of Forest Resources and Conservation at the University of Florida. Jason conducts research and extension programs on diseases of trees and forest health. His research includes disease diagnosis, biology/epidemiology and developing disease-resistant trees.  Before coming to Florida in 2006, Jason was a postdoctoral research associate in the Department of Plant Pathology at the University of Minnesota.

    Dr. Les Werner
A native of Wisconsin, Dr. Les Werner teaches Soils and Forestry at the University of Wisconsin at Stevens Point. Les obtained his Bachelor’s and Master’s degrees from UW - Stevens Point and his Ph.D from UW - Madison in 2008.  His research examines soil microbiology and how it is influenced by both natural and human induced changes in landscape environments.  Les has received numerous accommodations for his teaching and research while at UWSP from both students and the green industries.  Les’ goal is to make the soil live for all of his students regardless of age, so that they can manage their environments using what nature intended.
