The Crooked River National Grassland (CRNG) has a long history of a level of intensive management and associated environmental conditions which are typical of National Grasslands but which are uncharacteristic of the majority of National Forest System (NFS) lands.�� Since federal acquisition of these lands in the early to mid 30�s the administrative federal agencies have attempted to stabilize, rehabilitate and/or restore the system processes and functions on these lands, while, ��promot[ing] development of grassland agriculture and sustained yield management �� (36 CFR213.1, (c)).� On the CRNG many management activities have been employed over the years in order to accomplish these goals.� During the past forty years many of these CRNG management activities have been aimed at the control of the density and distribution of western juniper on this landscape.� During this same time period the spread and establishment of medusa head rye has increased dramatically often in association with implemented western juniper control practices.� In consultation with Dr. Tamzen Stringham and in cooperation with the Natural Conservation Service, National Forest/Grassland personnel have conducted intensive Ecological Site data collection in order to refine STMs and disturbance response groupings, and are utilizing these products to inform management decisions and better predict outcomes of management actions intended for landscape restoration particularly in relation to non-native invasive grasses.
