1a.Objectives (from AD-416):
Integrate and synthesize research information on multiple ecosystem services and pastureland production to address ecological condition and management on grazing lands, and assess tradeoffs between these multiple goals.
1b.Approach (from AD-416):
The American Forage and Grassland Council will facilitate a literature synthesis effort to document the effects of the following conservation practices: (1) prescribed grazing, (2) pasture and hayland planting, (3) pest management, and (4) nutrient management on pastureland in the USA. A final chapter will address an integrated assessment of the socio-economic concerns of implementing these practices.
Conduct multivariate and geospatial analyses of climate, soils and topography to refine and enhance the development of ecological site descriptions that reflect ecological and production attributes of pastureland. The new information obtained will be used to refine and enhance the Forage Suitability Groups now being developed by NRCS, and will additionally be used to refine the plant sampling protocols used for the pastureland National Resource Inventory.
The AFGC-facilitated literature review has been completed and sent to Allen Press to be typeset. The second component of this agreement requires multivariate and geospatial analyses of climate and topography. The results of these topo-climatic analyses are being used to inform the development of a quantitative site classification for temperate humid pastures in conjunction with remotely-sensed measurements. Consultation with NRCS CEAP personnel ensured that NRCS needs were being met.
