Division S-7 Forest Range Soils
S-7, Who we are! The Forest and Range Soils
(S-7) division of the Soil Science Society of
America presently has 368 members from 47 states
and 17 countries. As expected, the highest
percentage of membership comes from the major
forest states of the Pacific Northwest and
southeast US (Fig. 1). However, there is strong
membership in the Northeast and Northcentral
regions of the US as well. Canada has the highest
membership of any other coutry, with 29 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 (Fig. 3), 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 soil
science in the USA and the world. S-7, Where do
we come from? Fig. 1. Location of

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 useage of the home page has grown
considerably over time, and presently averages
about 4000 "hits" per week (Fig. 4). The
distribution list can be joined by contacting Rob
Harrison at robh_at_u.washington.edu, and
requesting to join. Messages can be posted to the
list by sending to the following address
