	abstract = {Dynamic soil property data can be collected during soil survey updates to add value to soil survey products and meet users needs for ecological site descriptions. Producers and land managers need information about soil and ecosystem change in order to plan for long-term productivity, conduct monitoring and assessments, and predict management effects on soil. Data collection technologies that can be used in the soil survey program are, however, not fully developed. A cooperative effort to develop sampling guidelines was initiated in 2004. NRCS is developing guidelines in cooperation with the Jornada Experimental Range (ARS), National Park Service, Forest Service and Bureau of Land Management. The guide for Sampling Dynamic Soil Properties integrates soil and vegetation data collection and interpretation. The guide emphasizes functionally important properties, field methods, and efficiency.},

	abstract = {The role of phytochemistry in diet selection by livestock on arid rangelands is being examined at the Jornada Experimental Range (JER) because shrub encroachment into arid and semiarid rangelands is a serious problem for livestock producers.  Palatability of these shrubs is often low due to high concentrations of secondary chemicals.  Our previous research has shown that crude extracts of tarbush (Flourensia cernua) applied to alfalfa pellets dramatically decreased intake by lambs.  However, little is known about how specific compounds affect herbivory.  Only 4 of the 19 terpenes we have examined reduced intake when tested individually (camphor, alpha-pinene, caryophyllene oxide, and camphene). Secondly, we are examining ways to control livestock in large pastures with fewer fences.  Directional Virtual Fencing (DVF{\texttrademark}) is being tested as a mechanism to contain livestock and improve grazing distribution.  This system uses ramped sound and electric shock administered on either side of an animal to keep it within a Virtual Paddock (VP{\texttrademark}) using minimum stress.  With GPS data obtained from animals, we determined that cattle and sheep bonded to cattle (i.e., a flerd) could be controlled using DVF{\texttrademark}.  A third study examines grazing behaviors of Mexican criollo cattle. Criollo cattle have coevolved with the arid and semiarid regions of North America for approximately 450 years and may have adaptations to arid environments that may be useful for livestock producers.  We imported cattle from the Chinipas region of Chihuahua to the JER and compared distance traveled by these animals to Angus x Hereford cattle in a 3000-acre pasture with good forage conditions.  Chinipas cattle traveled 7.9 {\textpm} 0.7 miles per day and covered a larger area of the pasture than Angus x Hereford cattle, which traveled 6.0 {\textpm} .4 miles.  These data support observations that criollo cattle travel further and use steeper slopes than British or Continental breeds.},
