Offered Papers Theme B: Grassland and the Environment
Description
Iowa grasslands consist mainly of introduced cool-season grasses and forbs. Many of these species are well adapted and have become naturalised. Most of these grasslands are located on marginal sites with heterogeneous soils and topography. Consequently, there is significant variation in the botanical composition and biomass productivity within and across grassland sites. This experiment aimed to evaluate the botanical composition and biomass productivity of representative grasslands and to determine if there was a relationship between grassland species diversity and biomass production across sites.
