Methods: 

Biomass was harvested from 0.1 m2 quadrats in each of the 12 subplots within the maximum and control whole-plot treatments. Biomass was clipped at the end of each growing season in 1998, 1999, 2000, 2005, and 2012 corresponding to 1, 2, 3, 8, and 15 years since the agricultural field was sown with native grasses and forbs. Biomass was dried for 1 week at 60oC, sorted into this and previous years' growth, and weighed.
