Because many areas are presently treeless, the name "loodland" is <br />nor always appropriate. Where trees exist and the land user plans woodland <br />use and management, Woodland may be shown. (Note: Soils having potential <br />plan[ communities that are treeless are described as range sites.) <br />Grazing value ratings (See Table): li = High, M = Pledium, and L = Low will <br />be used instead of range condition or "forage condition" classes to indicate <br />grazing value. Different grazing value ratings are to be separated on maps <br />by dotted lines. <br />Soils of the Riverbottom. 235 T <br />Soils of this tape are thosE~ bordering major streams and r.ributaries.
