Testing Disturbance Methods To Aid Interseeding Forbs In A Grass-Dominated Prairie Restoration In Northeast Indiana, Adam Thada
Master of Environmental Science (MES) Theses
Many tallgrass prairie restorations fail to match the level of biodiversity found in undisturbed prairie remnants. Restorations often become excessively dominated by warm-season grasses at the expense of forbs due to the lack of historical disturbance regimes. Interseeding new species often requires a disturbance mechanism to aid establishment of new plants. In April 2013, five native forb species were seeded into a restoration dominated by Andropogon gerardii (big bluestem). Two types of treatments were used in a factorial design: biomass removal by haying or burning, and application of a grass-specific herbicide. After one growing season, seedling counts of sown and …
Biodiversity Of Corticolous Macrolichens In A Selected Northeastern Indiana Forest And Implications For Conservation, Margaret L. (Gray) Kubina
Biodiversity Of Corticolous Macrolichens In A Selected Northeastern Indiana Forest And Implications For Conservation, Margaret L. (Gray) Kubina
Master of Environmental Science (MES) Theses
The hardwood forests of Indiana are experiencing a decline in oak (Quercus) regeneration. Most forests are undergoing sugar maple (Acer saccharum) replacement in the understory. This dynamic is of concern because of the potential decline in total species diversity in these forests. Lichens can be valuable indicators of forest health; however, they are not included in Indiana’s forest health monitoring program. An analysis of lichen biodiversity was conducted at Salamonie River State Forest (SRSF) in Wabash County, Indiana. The objectives of this study were to survey the current lichen biodiversity within SRSF in northeastern Indiana and …
