Abstract:
Grassland ecosystems are important wildlife habitat and have the potential to be a significant component of the new biobased economy. Most currently established grasslands in the Northeastern USA are on land with marginal crop production potential. Little is known about the plant composition or amount of biomass produced on these grasslands. To assemble a database for the resource assessment of warm season grasslands in the Northeastern USA we determined plant species composition at multiple scales using the modified Whittaker plot technique, measured various soil properties, and quantified biomass yield on CRP, WHIP, mine reclamation, and other grasslands. A total of 22 grasslands were sampled in New York, Pennsylvania, New Jersey, Maryland, and Virginia during September and October 2002.
We identified over 180 different plant species across the study region. Species richness was about 35 and biomass was about 6000 kg/ha, but both were quite variable by site. Although biomass yields were substantially lower than have been reported for monotypic switchgrass fields, minimal inputs may substantially increase the yields.
