Appendix A. A table showing the biomass of the six focal grass species in experimentally established field communities at Sedgwick Reserve from 2001 to 2005.

TABLE A1. The biomass (means and SD, n = 8) of the six focal grass species in experimentally established field communities at Sedgwick Reserve from 2001 to 2005. Focal species are three native perennial and three exotic annual grasses from three tribes. Plot treatments were: (1) established native perennial grass-dominated, (2) exotic annual grass-dominated, and (3) cross-seeded native perennial and exotic annual grass.
