A Comparison Of Two Mesic Sand Forests In Mason County, Illinois, David Timothy Coates
Masters Theses
The present study included surveys of a four hectare section of Barkhausen Conservation Area and a two hectare forested section in the Sand Prairie-Scrub Oak Nature Preserve. This study examines the floristic composition and structure of these forests, and some of the ecological parameters that may be responsible for their existence. In this study, the number, size and species of all living and dead standing trees (above 10 cm dbh) were recorded for each quadrat. The relative dominance, relative density, importance value, average diameter, density in broad diameter classes and basal area were then calculated for each species. Nested circular …

Black Oak Savannas And Pin Oak Flatwoods In Iroquois County, Illinois, Kenneth Johnson
Masters Theses
A vegetation survey was undertaken at the Iroquois County Conservation Area and the Hooper Branch Nature Preserve in Iroquois County, Illinois. Dry sand savanna, dry-mesic sand savanna, and Pin Oak flatwoods were the three communities under study at the Iroquois County Conservation Area. Carex pensylvanica had the highest relative frequency of any ground layer species present at both the dry and the dry-mesic sand savannas. In both of these sand savanna communities the dominant overstory tree was Quercus velutina. These two communities differed mainly in the composition of their woody ground layer species. Rubus hispidus obovalis had the highest relative …
