dc.description.abstract This study is an effort to provide new information on the effects of isolated tree canopies on understory vegetation composition and soil characteristics of northern Indiana black oak savannas. Temperate savannas in the United States have been greatly altered by human activities. Management of these areas is an important consideration for Midwest natural resource agencies. It is hypothesized that isolated trees within a savanna may alter the soil and plants around them, much in the same way that gaps in a forest canopy alter the plant composition and soil characteristics on the forest floor. In this study, isolated trees were selected in three northern Indiana black oak (Quercus velutina) savannas. Plots were located under the tree canopies and in adjacent open areas, in four directions from the tree stem. Populations of herbaceous plants were inventoried and the soil characteristics analyzed for both inside-canopy and outside-canopy plots. The environmental variables measured accounted for only about 20 percent of the variation in plant community between plots according to a Canonical Correspondence Analysis. Most of the variation in plant composition between plots was explained by pH, the amount of rain throughfall, and the thickness of the A horizon. It is clear that these black oak trees do alter the soil and plant composition around them. This information has implications for the long-term management of northern Indiana savannas.
