Description

S. scoparium is a perennial graminoid of the Poaceae family native to North America and Canada and introduced to Hawaii.[2] It is a primary groundcover species in longleaf pine forest. Bluestem grows both solitary and in clumps and reaches heights up to 4.5 feet tall with 10 inch long, narrow leaf blades. The plant possesses flowering spikes that grow on evenly distributed stalks up the stem. These flowers bloom in the fall and seeds disperse in November. There are a couple noted subspecies var. divergens (pinehill bluestem) and var. stoloniferum (creeping bluestem), the latter is only found in central longleaf pine range.[3][4][5][6]

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. [7] 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.[8] It is considered to be a species that is indicative of non-agricultural history on frequently burned longleaf pine habitat.[9]

S. scoparium became absent or decreased its occurrence in response to soil disturbance by agriculture in southwest Georgia. It has shown resistance to regrowth in reestablished pine forests that were disturbed by agricultural practices.[10]

Schizachyrium scoparium var. stoloniferum is frequent and abundant in the Peninsula Xeric Sandhills, Panhandle Xeric Sandhills, North Florida Subxeric Sandhills, Clayhill Longleaf Woodlands, Panhandle Silty Longleaf Woodlands, and Upper Panhandle Savannas community types as described in Carr et al. (2010).[11]

Phenology

S. scoparium has been observed to flower in November. [12]

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).[13] Populations have been known to persist through repeated annual burns.[14][15] A study found overall herbivory to decrease with higher fire return interval regiments.[9]

Herbivory and toxicology

S. scoparium has been observed to host bugs such as Scolops sulcipes (family Dictyopharidae).[16] S. scoparium has medium palatability for browsing animals and high palatability for grazing animals.[2] This species provides forage for cattle that can withstand heavier grazing.[17] It is sometimes foraged by common grasshoppers in the subfamilies Melanoplinae and Cyrtacanthacridinae, which are known as mixed feeders.[9] The plant also makes excellent nesting cover for the bobwhite quail and provides seeds for forage.[18][19][20][21]

Conservation, cultivation, and restoration

S. scoparium should avoid soil disturbance by agriculture to conserve its presence in pine communities.[10]
