Plant Communities
Soras are commonly reported in plant communities dominated by Cattails (Typha spp.), Sedges (Carex spp.), Bulrushes (Scirpus spp.), Smartweeds (Polygonum spp.), Rushes (Juncus spp.), Rice cutgrass (Leersia oryzoides), and Barnyard grasses (Echinochloa spp.).
Outside of wetlands, soras are most often reported in cultivated areas during migration or in the postbreeding period. For instance, a sora was observed 3 miles (5 km) from marshland in a cultivated field in Iowa in the middle of August. A male sora was observed less than 1,000 feet (300 m) from a large wetland in a soybean (Glycine max) field in northwestern Iowa during the postbreeding period. From early June to mid-July, soras were observed on farms in Saskatchewan sown mainly with wheat (Triticum aestivum).
Soras have also been reported in flooded wooded areas. In western New York, soras occurred during the breeding season on a study site where 26% of the area was categorized as "flooded timber," and 5% was classed as "scrub/shrub marsh". In eastern and central Maine, an average of 2.1 soras was observed in wooded swamps per 100 hours of observation during the breeding season. On a nonbreeding (August–April) site in southwestern Arizona, soras were found to use a "mixed shrub community" more than expected based on its availability. Soras were observed at low abundances on a site with Douglas-fir (Pseudotsuga menziesii), ponderosa pine (Pinus ponderosa), and trembling aspen (Populus tremuloides) in British Columbia.

Famous quotes containing the words plant and/or communities:
“Plant melons, harvest melons; plant beans, harvest beans.”
—Chinese proverb.
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
