Proper riparian management can provide numerous environmental, social, and economic benefits. At the USDA National Agroforestry Center, we are tailoring the land-use planning process to facilitate riparian management in the Western Corn Belt ecoregion for multiple benefits. This planning framework integrates regional, landscape and site scale planning approaches into a unified framework. In this framework, regional and landscape-scale public issues are addressed along with site-scale landowner objectives to facilitate balanced management plans providing broad mutual benefits. Our question-driven framework provides general guidance for inventory and analysis, preparation of planning objectives, and development and evaluation of management options. To support the …
National Association Of Rc&D Councils (Narc&Dc) Report: Rc&D Survey Of Agroforestry Practices
National Association Of Rc&D Councils (Narc&Dc) Report: Rc&D Survey Of Agroforestry Practices
USDA Forest Service / UNL Faculty Publications
This report summarizes the results of a national survey on agroforestry that was completed by Resource Conservation and Development (RC&D) Councils during the summer of 1999. The survey was designed to determine the extent and geographic location of agroforestry throughout the United States. Maps and graphs are used to illustrate where agroforestry practices are being used, where RC&D Councils are involved in agroforestry projects, and where there are opportunities to apply more agroforestry. It also suggests what types of assistance will be needed to enable landowners and support agencies to better advance the adoption of agroforestry.
Agroforestry is the integration …
Direct And Indirect Parametrization Of A Localized Model For The Mountain Pine Beetle — Lodgepole Pine System, Zy Biesinger, James Powell, Barbara Bentz, Jesse Logan
Direct And Indirect Parametrization Of A Localized Model For The Mountain Pine Beetle — Lodgepole Pine System, Zy Biesinger, James Powell, Barbara Bentz, Jesse Logan

The dynamic interaction between mountain pine beetles (MPB) and one of its hosts is reviewed briefly. The ‘local’ projection of a partial differential equation model describing this interaction is employed in model parameter estimation. Methods and assumptions for estimating non-fitted parameter values are given. Assigning values to non-fitted parameters, direct and indirect parametrization techniques are employed to estimate remaining parameter values. The indirect method is quickly and easily applied to many data sets but requires some assumptions and model simplifications. The direct method requires fewer assumptions but is computationally intensive. The results of these two techniques are compared and evaluated.
