Effects of Phosphorus and Nitrogen Manipulations on Tallgrass Prairie Restoration
The tallgrass prairie biome of North America once extended from Canada to the Gulf of Mexico. Only an estimated 1% of this important ecosystem remains today (Diamond and Smeins 1988; Samson and Knopf 1994), and these remnant prairie tracts are currently the focus of intense restoration and conservation efforts (Bock and Bock 1995; Kindscher and Tieszen 1998). In addition, conservationists have a very strong interest in restoring native tallgrass prairie communities in abandoned farmland tracts that are being allowed to revert to natural vegetation. A variety of prairie restoration methods are currently in use to achieve these goals, including the careful application of controlled fires, watering, re-seeding with native species, and the differential conditioning of grasses and forbs (Schramm 1990; Thompson 1992). Soil nutrient availability also plays an important role in the establishment and maintenance of native tallgrass prairie vegetation.
