The extent of forest, savanna, barrens, and prairie vegetation of Crawford County, Illinois, was mapped using the General Land Office survey notes of 1804-1821. Forest vegetation was the most exten- sive, covering 40.8% of the county, followed by prairie (34.2%), savanna (18.2%) and barrens (6.8%). Quercus alba L. (white oak) was the dominant forest species with an importance value (IV) of 60.6, followed by Q. velutina Lam. (black oak), Carya spp. (hickories), Ulmus spp. (elms), and Acer… Expand
Influence of Shrub Encroachment on the Soil Microbial Community Composition of Remnant Hill Prairies
Hill prairies are remnant grasslands perched on the bluffs of major river valleys, and because their steep slopes make them unsuitable for traditional row crop agriculture, they have some of theExpand
GRASSLAND-FOREST TRANSITION
Tallgrass prairie extends eastward in a narrowing peninsula across northern Illinois into adjacent Indiana. This vegetation reflects a longitudinal gradient of decreasing drought severity, and localExpand

Stability and instability in plant communities following fire
TLDR
Open canopy forests in fire susceptible areas accumulate fuels to levels that encourage fires of sufficient intensity to destabilize forest systems and convert them to open forests or savannahs, and on the forest-prairie edge, amounts and patterns of fuel accumulation, and species response to burning are such that fire can be considered to be a factor promoting stability.
