  • Floristic Quality Assessment Report
    FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al.

Their unfailing support has allowed me to pursue my dreams in all of life's endeavors. iii Abstract This thesis aims to explore the interactions between a potential biocontrol agent, the gall-wasp Aulacidea pilosellae, and its invasive Pilosella hawkweed hosts. I discovered that increased nitrogen availability improves P. officinarum vegetative growth, while also interacting with A. pilosellae to reduce vegetative growth, as the plants cannot compensate for this herbivory. I did not detect any nitrogen effects on wasp performance. I also explored how the host species utilized for galling affects wasp performance through two generations by measuring maternal effects. These only influenced offspring performance when the mother had utilized P. caespitosa, but not P. glomerata. I discovered that P. caespitosa is also the better offspring host, producing significantly larger galls and heavier larvae compared to P.

Plant Symbol = PAAU3 Status Contributed by: USDA, NRCS, National Plant Please consult the PLANTS Web site and your State Materials Center, Beltsville, MD Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values). Description and Adaptation Golden Ragwort is a member of the Aster family (Asteraceae). It is a somewhat weedy, short lived, perennial forb growing from 6 inches to 2 feet tall. The two very different kinds of leaves are highly distinctive. The blades of the basal leaves are 2 inches long and 2 inches across; they are cordate- orbicular in shape. The slender petioles of the basal leaves are 2 inches long. A flower stalk develops from the center of each rosette. Along this stalk, there are usually 2 – 3 alternate leaves. These leaves are smaller in size than the basal leaves and pinnatifid in shape. Both the alternate leaves and the stalk are hairless. The stalk ends in a flat-headed panicle of yellow flowers. The blooming period occurs early Wayne Hughes, used with permission spring (March – April) and lasts about 3 weeks. Each daisy-like flower is 1 inch across; in the center there Alternate Names are numerous golden yellow disk florets, which are Golden groundsel surrounded by 6-16 yellow ray florets.
