Lloyd Hulbert's death in May 1986 left a wealth of unfinished during the early part of the growing season (Hulbert 1988), and projects as well as the legacy of Konza Prairie Research Natural Area, may lead to a more productive (Abrams et al. 1986), lower di­ Kansas. One of these was an incomplete manuscript on fire, mowing, and versity, structurally more uniform grassland.

Waco, Texas 76798-7388, U.S.A. Houston, Texas 77098, U.S.A. [email protected] ABSTRACT Field studies at the Lawther - Deer Park Prairie Preserve, an area of approximately 21 ha (51 acres) of the Gulf Coast Prairies and Marshes vegetation area, have resulted in a description of the vegetation associations and an annotated checklist of the vascular flora. Six plant com- munity associations occur on the property: (1) the Upper Texas Coast Ingleside Sandy Wet Prairie; (2) Eastern Gamagrass - Switchgrass - Yellow Indiangrass Herbaceous Vegetation; (3) Gulf Cordgrass Herbaceous Vegetation; (4) Texas Gulf Coast Live Oak - Sugarberry Forest; (5) Little Bluestem - Slender Bluestem - Big Bluestem Herbaceous Vegetation, and (6) Natural Depressional Ponds. The checklist includes 407 species belonging to 247 genera and 86 families. Forty-six species are non-native. The best-represented families (with species number following) are Poaceae (84), Asteraceae (68), Cyperaceae (33), and Fabaceae (19). West Gulf Coastal Plain (eastern Texas and western Louisiana) endemics include Helenium drummondii, Liatris acidota, Oenothera lindheimeri, and Rudbeckia texana. One Texas endemic, Chloris texensis, a Species of Greater Conservation Need, is present.

  • Patterns and Consequences of Competition for Pollination Between Introduced and Native Species with Different Floral Traits by B
    Patterns and Consequences of Competition for Pollination between Introduced and Native Species with Different Floral Traits by Benjamin R. Montgomery A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Biology) in The University of Michigan 2007 Doctoral Committee: Associate Professor Beverly J. Rathcke, Chair Professor Deborah E. Goldberg Professor Earl E. Werner Emily D. Silverman, U.S. Fish and Wildlife Service Acknowledgements As I complete my dissertation, I am extremely appreciative of the amount of help many individuals and organizations have given me, without which I would not have been able to complete this work. I appreciate the patient guidance of my dissertation committee, including Beverly Rathcke, Deborah Goldberg, Earl Werner, and Emily Silverman, who persevered through many years of revised research plans, and provided encouragement and useful reality checks at various points in the process. Beyond guiding my dissertation research, all of my committee members were dedicated teachers and enthusiastic leaders of seminars that helped to broaden my graduate school experience. I am particularly thankful to Emily for remaining on my committee even after moving on from the University of Michigan. Of course, I want to thank Beverly, my committee chair, in particular for the guidance she has provided throughout this process. Beverly patiently listened to countless ideas throughout the process of developing my dissertation plans; she was generous with her time; she provided sound advice, and she mentored me in the art of presenting science in an accurate and compelling manner. Finally, I learned from Beverly how to host a great potluck, and I will miss her parties.

  • Blue-Eyed Grass, Sisyrinchium
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 28 June 2010 Blue-eyed grass, Sisyrinchium Despite it’s common name, blue-eyed grass is not a grass. The genus Sisyrinchium is a large group of annuals and perennials in the iris family (Iridaceae). But many species are low growing with narrow leaves that appear grass-like and many grow in grasslands. All are native to North or South America. Most are not well known and only a few are used as ornamentals. The taxonomy of the group is quite confused, so the number of species varies from 50 to 150, depending on which classifi cation system is used. Some species have many natural variants that were likely A grouping of Sisyrinchium angustifolium ‘Lucerne’. mis-named as species – so more research is needed to fi gure out the true relationships. Sisyrinchium plants all have clumps of stiff, upright, sword-shaped leaves held in a fan shape – just like most of their relatives in the iris family. However, the individual leaves are usually narrower than that of a typical iris plant, giving a grass-like appearance. They grow from thin rhizomes that gradually spread outward from the clump. In spring or summer small fl owers appear on spikes at or just above the foliage. Individual fl owers emerge from a green spathe slightly wider than the supporting branch. The star-shaped fl owers with 6 pointed tepals (three petals and three almost identical sepals, although the sepals are typically slightly wider than the petals) typically have a yellow center.

  • The Vascular Flora of the Natchez Trace Parkway
    THE VASCULAR FLORA OF THE NATCHEZ TRACE PARKWAY (Franklin, Tennessee to Natchez, Mississippi) Results of a Floristic Inventory August 2004 - August 2006 © Dale A. Kruse, 2007 © Dale A. Kruse 2007 DATE SUBMITTED 28 February 2008 PRINCIPLE INVESTIGATORS Stephan L. Hatch Dale A. Kruse S. M. Tracy Herbarium (TAES), Texas A & M University 2138 TAMU, College Station, Texas 77843-2138 SUBMITTED TO Gulf Coast Inventory and Monitoring Network Lafayette, Louisiana CONTRACT NUMBER J2115040013 EXECUTIVE SUMMARY The “Natchez Trace” has played an important role in transportation, trade, and communication in the region since pre-historic times. As the development and use of steamboats along the Mississippi River increased, travel on the Trace diminished and the route began to be reclaimed by nature. A renewed interest in the Trace began during, and following, the Great Depression. In the early 1930’s, then Mississippi congressman T. J. Busby promoted interest in the Trace from a historical perspective and also as an opportunity for employment in the area. Legislation was introduced by Busby to conduct a survey of the Trace and in 1936 actual construction of the modern roadway began. Development of the present Natchez Trace Parkway (NATR) which follows portions of the original route has continued since that time. The last segment of the NATR was completed in 2005. The federal lands that comprise the modern route total about 52,000 acres in 25 counties through the states of Alabama, Mississippi, and Tennessee. The route, about 445 miles long, is a manicured parkway with numerous associated rest stops, parks, and monuments. Current land use along the NATR includes upland forest, mesic prairie, wetland prairie, forested wetlands, interspersed with numerous small agricultural croplands.
