Optimization Of Grazing Management For Watershed Sediment Control, Y. Duan, P. Heilman, D. Phillip Guertin
Optimization Of Grazing Management For Watershed Sediment Control, Y. Duan, P. Heilman, D. Phillip Guertin
International Congress on Environmental Modelling and Software
Grazing on rangelands can increase erosion that is a major source of nonpoint source pollution. Grazing management is important in maintaining vegetation cover, which consequently impacts erosion and sediment yield. This paper uses a representative ranch model to define grazing management from an economic perspective. The model maximizes the profit of a representative ranch that can utilize all grazing lands in a watershed with constraints on forage resources, sustainable utilization, and production technology and sediment yield control objectives. A case study for the Walnut Gulch Watershed in Arizona showed a shift of the spatial distribution of optimal stocking rates with …

Urban Ecosystem Research Consortium of Portland/Vancouver
The UERC is a consortium of people from various universities and colleges, state and federal agencies, local governments, non-profit organizations and independent professionals interested in supporting urban ecosystem research and creating an information-sharing network of people that collect and use ecological data in the Portland/Vancouver area.
UERC Mission Statement:
To advance the state of the science of urban ecosystems and improve our understanding of them, with a focus on the Portland/Vancouver metropolitan region, by fostering communication and collaboration among researchers, managers and citizens at academic institutions, public agencies, local governments, non-profit organizations, and other interested groups.
The principal organizers span …
