David B. Hannaway
David is a forage specialist at Oregon State University with research, teaching, extension, and
international projects responsibilities. He began his agricultural studies at the University of
Delaware, completing a B.S. with Distinction in Plant Science in 1973. This involved
conducting undergraduate thesis research under the direction of his advisor Dr. Merle Teel.
David continued his studies at the University of Tennessee at Knoxville completing an M.S. in
Plant and Soil Science in 1975 under the guidance of Drs. John Reynolds and Henry Fribourg.
He finished his graduate studies at the University of Kentucky in 1979 with a Ph.D. in Plant
Physiology with Drs. Lowell Bush and Everett Leggett. Research work for all three degrees
included work on intermediary metabolism; specifically the role of mineral nutrition on the
absorption of potassium and magnesium and concomitant effects on organic acids and their role
in hypomagnesemia (grass tetany) in grazing livestock.
After extensive international travel in the spring of 1979, he began his career at Oregon State
University in Corvallis, Oregon. As an Assistant Professor he had statewide forage
responsibilities in extension, research, and teaching. In extension, he focused much of his energy
on developing forage species facts sheets and helping to establish and promote regional and
national standards for forage quality and testing. Research work included studying the impact of
soil and fertilizer nitrogen on biological nitrogen fixation in alfalfa. In 1985, he was promoted to
the rank of Associate Professor. Efforts in the late 1980's included developing various computer
software tools for assisting county agents and livestock producers in ration balancing and alfalfa
variety selection. He was promoted to Professor in 1994 following greater national efforts related
to developing research and extension goals for forage and grasslands and international projects
involving cooperative work with Tunisian and Chinese scientists. Projects involved publication
of a book describing the “Forage Resources of China” and investigating the potential for Chinese
use of cool-season grasses grown in Oregon.
His duties still involve extension, research, and teaching but focus has been placed on utilizing
electronic technologies to better educate, communicate, and facilitate cooperative work in the
areas of species adaptation and selection, grazing management, and forage/livestock systems.
Specifically, David has coordinated the development of the Forage Information System
(http://forages.oregonstate.edu), a web-based "virtual center" making accurate and current forage
information more widely accessible to all interested learners and decision makers throughout the
world by facilitating the cooperative work of forage extension, research, and teaching personnel.
Research focus has involved collaboration with Chris Daly (Professor and founding Director of
the PRISM Climate Group in the College of Engineering at Oregon State University) to develop
forage species suitability maps based on climate and soil information and using an innovative
Internet Mapserver application. A ten-year project funding by the USDA Foreign Agricultural
Service, the Oregon Seed Council, grass seed commissions, and cooperators in China resulted in
the publication of a China Map Atlas (http://www.prism.oregonstate.edu/products/china_atlas/)
displaying the climate, soil, and species suitability maps.
Professor Hannaway has recently completed two large projects with University of Tennessee
Professor Emeritus Henry Fribourg: (1) the Tall Fescue Monograph (both web-based and printed
versions (http://forages.oregonstate.edu/tallfescuemonogrph) and (2) USA Grasslands (part of the
FAO web segment on Country Pasture Profiles;
Professor Hannaway is the primary instructor for the spring-quarter undergraduate forages class
at Oregon State University (http://forages.oregonstate.edu/css310) and provides the technical
support for distance education versions of the class during fall and winter terms.
International activities in the past 15 years have focused on eastern and southeastern Asia, with
strong connections in China, Taiwan, Thailand, Viet Nam, and Indonesia. He has served as a
visiting scholar in the PRC, and received a Fulbright award as a Senior Scholar for developing
and presenting a “Results-based Management” workshop in Aceh Province with colleagues from
Thailand and Sri Lanka. He and two colleagues at Oregon State University organize and present
a yearly Summer Student Study Program for 20 Nanjing Agricultural University students to
provide them with an introduction to American culture and opportunities for post-graduate study
in the US. Previous year participants in this program are now graduate students in American,
Australian, and England universities.
Most recent research collaboration with Chris Daly involves assisting with developing suitability
maps for potential biofuel crops as part of the Sun Grant Initiative (http://www.sungrant.org/)
and other programs seeking to develop renewable sources of fuel from plant-based feedstocks.
Pending proposals involve modeling and mapping alfalfa for North America and China, and
grassland restoration projects in China and Mongolia.
