The Edmund Hayes Professorship in Silviculture Alternatives

Wishing to memorialize their father and honor his lifelong interest in forests, the Hayes family established the Edmund Hayes Professorship in Silviculture Alternatives in the Department of Forest Science at Oregon State University. Edmund "Ned" Hayes, Jr., and his siblings, Frederick Hayes, Philip Hayes, and Cornelia Hayes Stevens, created guidelines so the professorship will support efforts to restore and manage forests, and may eventually lead to new forestry practices.

Their father, Edmund Hayes, was an early pioneer in the forest industry who became a top executive at Weyerhaeuser and an advocate for reforestation.

"My father was always concerned about the forest resource in Oregon," Ned Hayes says. "He was interested in how it's used and how the forest is perpetuated." The chair preserves Edmund Hayes' belief in the values of education and silviculture: the science and art of growing trees.

"The professorship fit with what we wanted to do to memorialize our father and his interest in forest perpetuation. There's a lot to be known yet about growing trees and sustaining forests. As a family, we're pleased to develop this association with OSU. We're looking forward to seeing the results of the research."


Klaus J. Puettmann

Klaus PuettmannA professor in the Department of Forest Ecosystems and Society, Klaus Puettmann was named the holder of the Hayes Professorship in 2010. His research focuses on how plant interactions influence forest ecosystem development. This includes the influence of stand structure on tree and stand growth, regeneration, and biodiversity.

"My work deals with trying to develop silvicultural treatments that maintain or encourage ecosystem resilience and adaptability, while providing income, timber, wildlife habitat, clean water, and other goods," Puettmann says. "I believe much can be gained from linking the theories of complex adaptive systems to practical applications used by several silvicultural approaches, such as variable retention cutting, close-to-nature or continuous-cover silviculture, and other approaches that fall under the label of ecosystem management." He is the lead author of the 2009 book, Critique of Silviculture: Managing for Complexity.

After earning his undergraduate degree in Freiburg, Germany, Puettmann received his doctorate in Forest Science from OSU. He taught and conducted research at the University of Minnesota for nine years before returning to OSU to join the Department of Forest Science faculty in December 2000. He has served as a guest professor in Germany, has an adjunct appointment in Chile and taught a regeneration course for foresters from India, sponsored by United Nations Food and Agriculture Organization.
