    Shortgrass Steppe LTER: site review: July 11-13, 1999
    (Colorado State University. Libraries, 1999-07) Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author
    The site review agenda will begin formally on Sunday evening, at 6:30 pm, with a dinner for the site review team with the SGS-LTER Principal Investigators. We have planned the first full day in the field at the SGS headquarters, and the second day on campus at Colorado State University. For the agenda we have developed, the field day will focus on an overview of our conceptual framework, and our science. On the second day, we will address some of the other important aspects of the SGS LTER, including our information management, education/outreach, leadership plan, and the institutional relationships for the project. We felt that it was important to plan carefully how we can best present our work to you, but also understand that it is most important to respond to the questions that you have for us, and to be flexible as the days proceed.

    Central Plains LTER project: site review: field day
    (Colorado State University. Libraries, 1993-09-08) Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author
    The LTER program began with spatially explicit ideas and questions about the importance of landscape structure, and particularly the classic soil catena model, in the long-term development and maintenance of shortgrass steppe ecosystems.

    Central Plains Experimental Range long term ecological research: site review, June 1989
    (Colorado State University. Libraries, 1989-06) Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author
    Our approach to the LTER program has explicitly considered system behavior across a range of spatial and temporal scales. Our work has spanned spatial scales from individual plants to the central grassland region of the United States, focusing on annual to century level implications. In our approach to LTER we assumed that an important criterion for judging the significance of our LTER-funded work at the Central Plains Experimental Range would be our ability to generalize results beyond the boundaries of the site. Because we are interested in spatial and temporal scales that exceed the boundaries of a single site, we have emphasized observations and experiments with a spatially explicit dimension, as well as technologies to deal with the analysis and extrapolation of spatial information. These technologies include simulation modeling and geographic information systems.

    CPER field day, August 24, 1990
    (Colorado State University. Libraries, 1990-08-24) Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author
    Research at the site on the CPER is being conducted by the ARS Hydro-Ecosystem Research Unit in cooperation with the LTER program on the Shortgrass Steppe. The objective of hydrology research being conducted by the Hydro-Ecosystem Research group of the ARS at CPER in cooperation with the CPER/LTER project is to validate a spatially explicit hydrologic simulation model for semiarid grassland, and to provide long-term observation of hillslope hydrologic processes. The research involves both natural runoff plots and rainfall simulation studies.
