Taxonomic Notes
Synonym: M. capillaris var. trichopodes (Elliott) Vasey
Variety: none
Description
M. expansa is a perennial graminoid of the Poaceae family that is native to North America. [1]
Distribution
The southeastern region of the United States is the native range of M. expansa; specifically in FLorida, Georgia, South Carolina, North Carolina, Virginia, Kentucky, Alabama, Mississippi, Louisiana, and Texas. [1]
Ecology
Habitat
Fine textured soils, and strongly acid sands are part of the ideal habitat for M. expansa [1] In general, pine savannas, pine flatwoods, and mesic areas in sandhill-pocosin ecotones are the environments where M. expansa can be found. [3] Specimens have been taken from flatwoods with pine savanna sandy loam. [4] When exposed to soil disturbance by military training in West Georgia, M. expansa responds negatively by way of absence.[5]
M. expansa has been determined as an indicator species for the Henslow's Sparrows habitats in southeastern Louisiana, it is one of the preferred seeds of the sparrow. [6]
Phenology
April is the common month where much of the growth happens for M. expansa. Seeds are produced during the late summer months that can be dispersed throughout the following year. [1]
Fire ecology
Burning is a successful solution to managing the grass. [1]
Use by animals
Animals use the grass for forage but is not used as a food source for any animal apart from some livestock but even then it is not their entire food source. [1]
Conservation and Management
Cultivation and restoration
