Vr``".D ~ `tom f~,P Soil Conservation Service Colorado August 1971 Guide for Identifying Grazable Woodland MLRA's 34, 35, 47, 48, 49, 51 69 Technical Cuide Section II-F Woodland Grazable woodland is forest land on which the understory includes, as an integral part of the forest plant community, plants which can be grazed without significantly impairing other forest values. In Colorado, grazable woodlands consist of certain pinyon-juniper, ponder- osa pine and aspen forests which have the potential to produce significant, predictable understory vegetation suitable for forage for livestock and big game. Other woodlands do not normally provide significant vegetation suitable for grazing. These include dense ponderosa pine, lodgepole pine, mixed conifer and spruce-fir types. These will not be considered as grazable except where grazing is available due to an area being cut over or burned. In these cases, management trill be based on the mayor forage species in the understory. The following table illustrates, for planning purposes, the present classi- fication of tree covered land in Colorado.
