Research Project: Using Land Resource Units to Improve CEAP Analysis and Ecological Site Interpretation

Location: Range Management Research

Project Number: 3050-11210-007-29-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jun 1, 2013
End Date: Dec 31, 2014

Adapting CEAP modeling and prediction efforts to rangelands will require an approach to identify the effects of conservation practices on both critical ecological processes and relevant spatial scales.

We will identify representative landscapes (analogous to Land Resource Units) within each of the 5 Land Resource Regions (LRRs C, D, E, G, H) dominated by rangeland as a land cover. Within each of the LRRs, 3 MLRAs will be selected and quantitative information for dominant soils, vegetation, topography, and climate and their relationships for each LRU will be collected and organized. Using this information, the APEX model will be parameterized for hydrology, soil carbon and wildlife habitat relationships. The likely effects of common conservation practices on soil/vegetation relationships at the site level (state change) and the impacts of cumulative site level state change on landscape and regional scale ecosystem processes will be assessed.
