To protect our urban forests, which are threatened by pests and pathogens, a greater variety of tree species is necessary.

 

For our fourth annual conference we will continue to explore the relationships between landscape design, horticultural practices and the use of a greater variety of tree species.

 

Between them, our speakers this year boast an extravagant depth of experience ranging from worldwide plant exploration to landscape and garden design, promotion of new plant materials, administration of some of our country's most noted horticultural conferences and institutions and hands-on experience with plant testing and data collection.

Jeff Iles | "The Iowa Experience"

Jeff, with his many years as a key figure in the widely-attended Iowa Shade Tree Short Course--now in its 61st year!--will draw on his experience to give us his best ideas for underutilized tree species for planting in our region. He will also devote a major portion of his talk to recommending pruning practices for maximizing the longevity of all those new trees we've been planting and will keep planting in the future.

Jeff serves as Professor and Chair of the Department of Horticulture at Iowa State University (Ames, IA). He teaches, conducts applied research, and provides Extension programming in the areas of landscape plant establishment and maintenance, woody plant evaluation, and nursery and garden center management. He received his B.S., M.S. and Ph.D. degrees in horticulture from Michigan State, Penn State, and Iowa State, respectively. Between degrees, Jeff worked in the retail garden center segment of the green industry, first in suburban Detroit, Michigan, and later in Littleton, Colorado.
