double dagger]) Early Agropyron repens and Rudbeckia hirta were all but absent in 1993 except in plots burned in midsummer; ANOVAS with all or most cells empty from other treatments are inappropriate.
After two burn cycles, uneven presence (resulting in high variance and low mean cover) precluded statistical demonstration of responses by Agropyron repens, Erigeron annuus, and Rudbeckia hirta that were evident after one burn cycle (Howe 1994a), when mean cover was higher and each species was present in most plots.
After spring burns, rankings of dominants ranged in mean cover from 25 to 53%, with Andropogon gerardii [is greater than] Solidago altissima [is greater than] Aster simplex = Phalaris arundinacea = Panicum virgatum = Agropyron repens [is greater than] Erigeron annuus (trace) [is greater than] Rudbeckia hirta (absent).
A few species, especially Poa pratensis and Agropyron repens, dominated high nitrogen plots once they were present on them.
For example, the average frequency of all species was lowest in the savanna, as was the frequency of Agropyron repens, the species that was most commonly dominant on high nitrogen plots in the younger fields.
Agropyron repens, the species that dominated high nitrogen treatments during the 11 yr reported here, was widespread in field A at the start of the experiment.
