Division S-7 Forest & Range Soils
S-7, Who we are!
S-7 “Family Tree”
S-7 DistList and Home Page!!!
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.
Since 1996, the S-7 division
has maintained a distribution
list and home page. The home
page is located at:
http://soilslab.cfr.washington.e
du/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:

requesting to join. Messages
