Research Project: CONSERVATION EFFECTS ASSESSMENT PROJECT - GRAZINGLANDS (2010-2011)

Location: Range Management Research

Project Number: 6235-11210-006-91
Project Type: Reimbursable

Start Date: Oct 01, 2009
End Date: Sep 30, 2011

Objective:
Continue to develop research-based recommendations to increase the ability of the USDA-NRCS to assess the effects of conservation practices, in particular through the enhancement of NRI data collection, analysis, and interpretation. In 2010, we will specifically work to modify NRI to increase sensitivity to conservation treatment effects through modification of sampling framework and integration and enhancement of existing air photo acquisition (higher resolution, more coordinated with ground measures) and analysis. Increase model accuracy, precision, and predictive capacity and integrate into NRI. Develop techniques for integrating new remote sensing technologies into NRI to facilitate CEAP practice effects estimation. Support collaborative development of wind erosion models.

Approach:
Remote sensing integration. Continue to develop and test remote sensing acquisition and interpretation technologies. Sampling design. Optimize statistical design to address both local and national requirements for precision. Coordinate and integrate model parameter and ground-based measurements so that ground based measurements can be used to (a) generate statistics at both national and (where sufficient replication exists) local scales, (b) calibrate photo-interpretation, and (c) provide input data for models. Finally we will integrate NRI with research and model results using ecological site descriptions to support future Conservation Effects Assessments at national and local scales and support changes in field technology used to sample NRI on-site field locations.
