  6. Emerald Ash Borer (Agrilus planipennis): Towards a Classifcation of Tree Health and Early Detection

    Peters, Matthew P.; Iverson, Louis R.; Sydnor, T. Davis
    Forty-five green ash (Fraxinus pennsylvanica) street trees in Toledo, Ohio were photographed, measured, and visually rated for conditions related to emerald ash borer (Agrilus planipennis)(EAB) attacks. These trees were later removed, and sections were examined from each tree to determine the length of time that growth rates had been impacted. A classification system was developed to discern the health of the trees along with a proposed method for early detection of a declining state of vigor. The classification is not an indicator of the degree of infestation, but rather tree health, which may be linked to the degree of EAB...

  7. Spiders (Araneae) of the Glen Helen Nature Preserve, Greene County, OH

    Bradley, Richard A.; Hickman, William L.
    The purpose of the current project was to assess the species diversity of spiders (Araneae) at Glen Helen Nature Preserve and compare it to the diversity of spiders at other forest sites in the region. Glen Helen Nature Preserve is located near the village of Yellow Springs, Greene County, OH. The reserve area is 404.6 hectares. The primary habitat is mixed mesophytic hardwood forest. In addition to forested areas, spider sampling was conducted in old field and restored tallgrass prairie habitats. Samples were collected between 4 November 1993 and 1 September 2008 with the preponderance of sampling occurring during summer....
