Description
This ecological site is a tallgrass prairie. Historic accounts and a few remnant locations show evidence of the prairie. The site's productive, yet sometimes droughty, soils provide a good medium for frequent fires. Dormant season and late-growing season fires are estimated to have occurred every one to three years.
Submodel
Description
Prolonged absence of fire in the Prairie State will transition into the Forest State. Without natural fire intervals of one to three years, woody species become established. Within a few years they can grow to a height where fire is ineffective at controlling their growth. They eventually grow to densities where light is restricted to the grasses and forbs, and only shade tolerant species can thrive.
Submodel
Description
The Plantation State is a result of conversion activities. The landowner has maximized silviculture production by planting a monoculture of tree species.
Submodel
Mechanism
The transition from State 1 to State 2 is a result of time and long periods of no fire. Without fire to suppress seedlings, biomass and diversity is lost from the grass and forb layers.
Mechanism
The transition is due to the land manager maximizing silviculture potential. If present, merchantable timber is harvested by clearcut, then the site is prepared and planted to a monoculture of trees.
Mechanism
The transition is due to the land manager maximizing agricultural production. If present, merchantable timber is harvested by clearcut, then the site is prepared and planted to either a tame grass or row crop.
Mechanism
Restoration of this community to the reference state begins with a timber harvest. Removing trees opens up the canopy, allowing sunlight penetration to the ground. If the land has been forested for many decades, native seeds may be required if a seedbank does not exist. After a successful stand of grass has returned, natural burn intervals are required to keep woody species controlled.
