Accomplishments
The following outcomes are organized by the objectives in our petition.
1)Station reports were presented in both oral and written formats. The presentation of station reports allows the members of the committee to discuss recent research efforts as well as proposed research efforts in the area of improving forage utilization by ruminants. In addition, discussion of the station reports often fosters new research ideas and potentially leads to collaboration on research among committee members. Station reports were combined into an annual written report that provides a comprehensive review of current research being conducted by members of the WCC-110 committee. This report was distributed to all members of the committee as well as AES directors of contributing institutions.
1 & 2) A field tour of the Deseret Land and Livestock Company was conducted. This field tour not only allowed us to discuss potential research with a producer fostering new ideas it also allowed us to present technology to the producer.
2 & 3) The WCC-110 produced a symposium titled Livestock Grazing Distribution: Impacts on Enterprise and Environmental Sustainability. This symposium was held in conjunction with the 2003 SRM meetings in Casper, WY. Over 200 people attended the symposium. Attendees included range and livestock researchers, extension personnel, government agency personnel, and livestock producers. The symposium provided not only a means to transfer technology but also a means to promote implementation of management strategies to increase sustainability of grazing livestock production.
Plans for the upcoming year
1) Develop a web site for the WCC-110 committee that will further enhance the ability to share research results and proposals as well as improve our ability to transfer technology to our stakeholders.
2) Rewrite and submit a new petition to improve our ability to serve our stakeholders.
3)Conduct an annual meeting during the summer of 2003 that will include an educational event appropriate to our membership, graduate students, and extension and industry colleagues, as well as coordination of research and extension efforts through station reports.

Impacts
- Transferred technology to livestock producers, extension personnel, government agency personnel, and producers through a symposium
- Developed and transferred innovative livestock management strategies by research and extension efforts of committee members
- Created an opportunity for range scientist to gain continuing education credits related to livestock distribution through a symposium
