Forest Service, Shawnee and Hoosier National Forests, for the opportunity to compile these conservation assessments and for their invaluable assistance with data and field opportunities. Mark Basinger, Stan McTaggart, Steve Olson, Beth Shimp, and Steve Widowski were particularly helpful in facilitating both the cost share agreement and fieldwork. I would also like to thank the staff of the Illinois Natural History Survey, Champaign, for their assistance with logistics necessary to complete these reports. I would especially like to thank John Taft for help in initiating these studies. Several people assisted by contributing information on this vine. Among these, John Schwegman was particularly helpful in providing information on Lonicera in southern Illinois, Anita Cholewa provided information on the plant from the University of Minnesota collections, George Yatskievych provided information on Missouri populations, and Steve Ginzbarg provided collection information from the University of Alabama herbarium (UNA). Gordon Tucker and John Ebinger provided specimens for this study from the Eastern Illinois University herbarium, and the staff of the University of Wisconsin herbarium were especially helpful during a visit to their herbarium for ane examination of their specimens. Dr. K. Gandhi, Harvard University, kindly confirmed information regarding the nomenclature for this species. Additional thanks are extended to Ariane Hoard, my student at the University of Illinois during the summer of 2002, for her help in searching for information on the Internet and literature in support of several of these assessments (W-1), and to my assistant Sherry Weaver for her continuing assistance in database management and processing the plant specimen vouchers. This material is based upon work supported by the U.S.D.A. Forest Service, Eastern Region, under Cost Share Award No. AG 01CS-11090804-032 (1-5-28861).

Forest Service, Eastern Region. ConservationAssessment for Yellow honeysuckle (Loniceraflava Sims) EXECUTIVE SUMMARY This Conservation Assessment is a review of the distribution, habitat, ecology, and population biology of the Yellow honeysuckle, Loniceraflava Sims, throughout the United States, and in the U.S.D.A. Forest Service lands, Eastern Region (Region 9), in particular. This document also serves to update knowledge about the status, potential threats, and conservation efforts regarding the Yellow honeysuckle to date. The Yellow honeysuckle is a perennial fibrous vine that has pale yellow, yellow-orange, to orange flowers, globose reddish-orange berries, and it has leaves that have a hairless upper surface and a glabrous to somewhat villous-pubescent undersurface; the hairs, if present, are normally restricted to the larger leaf veins. The undersurface of the leaves is slightly gray green or pale but not conspicuously whitened (glaucous) at maturity. The species is generally recognized as distinct by botanists, but there is some disagreement in the literature regarding varieties. In addition, the Yellow honeysuckle may be of hybrid origin or it may have hybridized extensively with other species in some portions of its range, including Illinois. The vine grows mainly in rocky open forests, bluff ledges and cliffs, and in rocky ground along streams. The species is found only in the central to southeastern United States (historically in 12 states) and nowhere else in the world. It propagates primarily by seeds, but its stems are capable of rooting and new plants are easily established. Globally, the species ranking is G5? (probably secure world-wide, but some additional information is needed). The Yellow honeysuckle is listed as Endangered in Illinois, of Special Concern in Tennessee, and Presumed Extirpated in Ohio. It is also considered to be critically imperiled in Kansas. The Yellow honeysuckle has been included on the Regional Forester Sensitive Species list (RFSS) for the Shawnee National Forest but not the Hoosier National Forest, where it has not been reported. In Illinois the species is critically imperiled and it is considered vulnerable because it has very few known occurrences. It faces extirpation in Illinois if it is not properly protected. In addition to species listed as endangered or threatened under the Endangered Species Act (ESA), or species of Concern by U.S. Fish and Wildlife Service, the Forest Service lists species that are Sensitive within each region (RFSS). The National Forest Management Act and U.S. Forest Service policy require that National Forest System land be managed to maintain viable populations of all native plant and animal species. A viable population is one that has the estimated numbers and distribution of reproductive individuals to ensure the continued existence of the species throughout its range within a given planning area.

Mason-Gamer Abstract.—The Lonicera clade Caprifolium contains 25 species distributed around the Northern Hemisphere, including in the Mediterranean climates of California and Europe.∼ We sequenced the second intron of LFY to help resolve relationships within the clade where the internal transcribed spacer and chloroplast markers had previously failed to do so. Divergence Downloaded from time estimation and biogeographic analyses over the posterior distribution of dated trees suggest that a widespread an- cestor was distributed across the Northern Hemisphere some 7–17 million years ago. Asian species form a sister group to a clade in which the European species are sister to the North American species. We use climatic niche modeling and divergence time estimates to explore the evolution of climate variables in the group.

In this plan, we will briefly introduce the physical and biological setting, past land use, and current uses of the Domain. The remainder of the plan consists of an assessment of the forest, which has been divided into six conservation areas. These conservation areas contain multiple management compartments, and the six areas have similarities in topographical position and past land use. Finally, the desired future condition and project summary of each conservation area and compartment has been outlined. Background The University of the South consists of an academic campus (382 acres) with adjacent commercial and residential areas (783 acres) that are embedded within and surrounded by diverse natural lands (11,838 acres). The term “Domain” is used interchangeably to describe both the entire ~13,000 acres and the 11,800-acre natural land matrix (also referred to as the “Greater Domain”).

No part of this publication may be reproduced, stored in a retrieval system or database, or transmitted in any form or by any means, including photocopying, without written permission of the authors. Produced with financial assistance from The Couchiching Conservancy. The City of Kawartha Lakes Flora Project is sponsored by the Kawartha Field Naturalists based in Fenelon Falls, Ontario. In 2008, information about plants in CKL was scattered and scarce. At the urging of Michael Oldham, Biologist at the Natural Heritage Information Centre at the Ontario Ministry of Natural Resources and Forestry, Dale Leadbeater and Anne Barbour formed a committee with goals to: • Generate a list of species found in CKL and their distribution, vouchered by specimens to be housed at the Royal Ontario Museum in Toronto, making them available for future study by the scientific community; • Improve understanding of natural heritage systems in the CKL; • Provide insight into changes in the local plant communities as a result of pressures from introduced species, climate change and population growth; and, • Publish the findings of the project . Over eight years, more than 200 volunteers and landowners collected almost 2000 voucher specimens, with the permission of landowners. Over 10,000 observations and literature records have been databased. The project has documented 150 new species of which 60 are introduced, 90 are native and one species that had never been reported in Ontario to date.

After graduation from college, he moved to Eastern Oklahoma State College where he took a position as Instructor in Botany and Agronomy. In the course of conducting botany field trips and working with local residents on their plant problems, the author became increasingly interested in the flora of that area and of the State of Oklahoma. This led to an extensive study of the northern portion of the Oauchita Highlands with collections currently numbering approximately 4,200. The specimens have been processed according to standard herbarium procedures. The first set has been placed in the Herbarium of Oklahoma State University with the second set going to Eastern Oklahoma State College at Wilburton.
