Rich Flora

A remarkable prairie outlier was recently discovered in central Ontario. The site had about 1.6 ha of open prairie surrounded by 11 ha of Quercus rubra – Pinus strobus savanna. The savanna had a density of about 27 huge, open-grown trees per hectare (11 per acre). The vegetation of the prairie opening comprised four zones ranging from a dry sand barrens to a mesic to wet-mesic prairie arrayed on a gentle slope. The major dominants overall were Sorghastrum nutans, Andropogon scoparius, Danthonia spicata, Lespedeza capitata, Desmodium canadense, Aster azureus, Monarda fistulosa, Solidago nemoralis, Aster sagittifolius, Equisetum hyemale, Car ex rugosperma, and Panicum linearifolium. The site had a rich flora of 115 species, of which more than one-third were listed as prevalent or modal species of Wisconsin prairies and related communities, occurring more than 800 km to the west. In addition, about 15% of the species in the prairie opening were regionally rare and three, Carex richardsonii, Lespedeza intermedia, and Scirpus clintonii, were considered rare in Ontario.

Stipa Comata

Six native grass species, Bouteloua gracilis, Stipa comata, Koeleria cristata, Festuca scabrella, Andropogon scoparius, and Danthonia parryi, and six introduced grass species, Elymus junceus, Bromus inermis, Agropyron cristatum, Agropyron tricophorum, Festuca rubra, and Dactylis glomerata, were germinated and grown for 90 days at root-zone temperatures of 7, 13, 18, and 27 °C. In general, the introduced species were superior to the native species in percentage germination and speed of germination and germinated, emerged and grew more readily at lower root-zone temperatures. Introduced species produced about 10 times as much weight of leaf and about eight times as much weight of root as did the native species at comparable growth stages. The chances of establishment and successful early growth of seeded stands appeared to be better with introduced grass species than with native grass species.
