- Library Collection RecordThe greatest threat to eastern North American biodiversity is the loss of eastern grasslands, especially those found in the southern states. Prior to European settlement, grasslands (including…Publication Date 2018
- Library Collection RecordThis study highlights one of the many successful and progressive ranching operations and the people on the land who are doing the work in Arizona. In 1993, Anita Waite and Sherwood Koehn moved from…Publication Date 2018
- Library Collection RecordNative grasslands of various types were once abundant in the southeastern United States ("the South"), but have declined so much that even many ecologists have not recognized their…Publication Date 2018
- Library Collection RecordLivestock management in mesic meadow pastures is of interest to industry, range managers, and conservationists because of the need to understand how best to accommodate livestock and wildlife.�…Publication Date 2018
- Library Collection RecordWestern and Utah juniper (WJ and UJ) woodlands have been expanding in range and infilling. Extensive resources have been spent managing theses woodlands, so understanding seed dispersal is critical…Publication Date 2018
- Library Collection RecordWild horses and domesticated livestock can have direct and indirect effects on the structure and composition of riparian areas and the hydrologic function of the associated ecosystem.� In arid…Publication Date 2018
- Library Collection RecordIn conifer-encroached areas, one mechanism thought to contribute to the loss of understory species is the interception of precipitation by the increasing tree canopy. Effective precipitation may be…Publication Date 2018
