Applied Uses of Prairies Research

Almost none of Iowa's native tallgrass prairies remain, and most of what remains is due to prairie restorations.  Yet it is unlikely that prairie restorations conducted solely for ecological purposes will result in the reestablishment of significant portions tallgrass prairies.  Using restored prairies for profit gaining purposes, however, may encourage prairie restorations.  Prairies can potentially be used for multiple applied purposes, some of which are currently economically valued and some of which are likely to be economically valued in the near future.  The biomass of prairies can be used directly as a cellulosic biofuel feedstock or as forage for grazing livestock.

Prairies can also provide ecological services such as carbon sequestration, reductions in nutrient pollution, and enhancement of beneficial insects, all of which are likely to have economic value in the future.  The management and diversity of prairies grown for applied uses differ, and knowledge of the desired use of the prairie is important in determining the appropriate prairie characteristics.

Matt Liebman and I wrote an ISU University Extension publication that discusses how to establish and manage prairies in addition to potentially profit-gaining uses for prairies.  Hard copies of the publication can be purchased from the University Extension store and PDFs of the publication can be downloaded below or from the University Extension store.
