Woody Plant Encroachment and Ecosystem Biogeochemistry

TABLE 2 Contrasts in Aboveground Net Primary Production (ANPP), Soil Physical Properties, Organic Carbon and Total Nitrogen Pools (0- to 10-cni depth), and Fluxes in Soils Associated with Woody Plant and Grazed Grassland Communities in a Sandy Loam Upland Landscape at the La Copita Research Area in Southern Texas 

Maximum and minimum monthly values for samples obtained over an annual cycle are shown for root-standing crop (coarse roots aO. l-min diameter) a range is presented for ANPP and Qk,. All other values are means 

On a regional basis, shifts from grass to woody plant domination have the potential to influence biophysical aspects of land-atmosphere interactions, such as albedo, evapotranspiration, boundary layer conditions, and dust loading (e.g., Bryant et al,
