Description

S. scoparium is a perennial graminoid of the Poaceae family native to North America and Canada and introduced to Hawaii. [2]

Distribution

S. scoparium is found: everywhere in the United States excluding Oregon and Nevada; every region in Canada; every island in Hawaii. [2]

Ecology

Habitat

S. scoparium proliferates in various open habitats, in a wide range of moist to dry habitats, fall-line sandhills in the inner Coastal Plain, perhaps in other dry habitats. [1] It also occurs often in relic P. palustris/wiregrass communities. [3] Specimens have been collected from wet pine flatwoods, palmetto slash pine woodland, oak-palmetto woodland, blaffs along river, treeless chalk glade, wet road ditch, cypress swamp, dry glade, palm hammock, sand-pine oak woodland, slashpine savanna, longleaf pine sand ridge, pine flatwoods, longleaf pine wiregrass savanna, upland old field, pond pine flatwoods, and open river banks.[4] It is considered to be a species that is indicative of non-agricultural history on frequently burned longleaf pine habitat.[5] S. scoparium responds negatively to soil disturbance by agriculture in Southwest Georgia.[6]

Schizachyrium scoparium var. stoloniferum is frequent and abundant in the Peninsula Xeric Sandhills, Panhandle Xeric Sandhills, and North Florida Subxeric Sandhills community types as described in Carr et al. (2010).[7]

Phenology

S. scoparium has been observed to flower in November. [8]

Fire ecology

S. scoparium is highly fire tolerant, resprouting quickly following fire, and is the dominant grass species in some fire-dependent communities (e.g., western upland longleaf pine forest).[9] A study found overall herbivory to decrease with higher fire return interval regiments.[5]

Use by animals

S. scoparium has medium palatability for browsing animals and high palatability for grazing animals. [2] It is sometimes foraged by common grasshoppers in the subfamilies Melanoplinae and Cyrtacanthacridinae, which are known as mixed feeders.[5]
