There are 767 members that choose S-7 as a n affiliation, but not their first division. As expected, the highest percentage of membership comes from the major forest states of the Pacific Northwest, Southeast, and Northcentral US (Fig. 1). However, there is strong membership elsewhere in the US as well. Canada has the highest membership of any other country, with 25 members from essentially all over Canada (Fig. 2). Membership represents all continents except Antartica. Forest soils has been represented in SSSA since its inception in 1937, and was then known as V-A, Forest Soils. A vote of 419 to 9 established the Forest and Range Soils Division in 1954, and it has been active ever since. A loose affiliation exists with the International Soil Science Society, of which many are also members. The S-7 division is one of the strongest institutions considering Forest and Range Soil Science in the USA and the world. • S-7, Where do we come from? • Fig. 1. Location of S-7 members in US & world. S-7 DistList and Home Page!!! Since 1996, the S-7 division has maintained a distribution list and home page. The home page is located at: http://soilslab.cfr.washington.edu/S-7/ The usage of the home page has grown considerably over time, and presently averages about 8000 "hits" per week (Fig. 3).

S-7 list view and useage over time. Garth Voigt Dedication. The following is a dedication for the proceedings of the 9th North American Forest Soils Conference. (Conferences are held every 5 years. Garth had contributed papers to the first three of these conferences, in 1958, 1963 and 1968, as well as writing numerous other scientific publications which contributed greatly to our understandings of forest soil science. Garth’s mentoring strongly influenced numerous graduate students, including many who are researching and teaching forestry and soil science today.) Garth Voigt, native of Merrill in central Wisconsin, studied soil science and plant physiology at the University of Wisconsin, Madison, where he completed his Ph.D. in 1951, working with Sergei “Doc” Wilde and other forest soils peers of the era there. These included Don White, Don Mader, Earl Stone, Gene Steinbrenner, Chet Youngberg, Chuck Davey and others who have contributed to previous NAFSC volumes. During 1950 to 1954 Garth was Instructor and Assistant Professor of Soil Science at Wisconsin. From 1954 through 1988 Garth was Assistant, Associate, Professor, then Margaret K. Musser Professor in the Yale School of Forestry (and, latterly Environmental Studies), where he also served three terms as Acting Dean. At Yale Garth’s collaborations with Professors H. J. Lutz, D. M. Smith and F. H. Bormann and hundreds of graduate students led to expanded horizons and deepened insights of forest-soils interactions. Garth’s research combined plant physiology and soil science in investigations of root system sorption of nutrients, mycorrhizae, mineral weathering in rhizospheres, soil nitrogen dynamics, acid rain, and “biogeochemistry” before the term became common jargon. Garth’s keen intellectual insights, kind, gentle, dry-humored manner, and firm and encouraging mentorship influenced numerous M.F., M.S. and PhD students and others who benefited from his congenial friendship and insightful writings. His presence and work had strong influence on integrating soil science and silviculture. An avid fly fisherman and conservationist, Garth was active in wetlands and waterways conservation in Connecticut and has long been involved with the Henry’s Fork Foundation in Idaho, open spaces issues in Bozeman, and science matters with the Greater Yellowstone Coalition. Garth and his lifelong companion and wife, Jane, reside in Bozeman, Montana, close to trout, trails and wild places. Who: From Duke-D. D.
