The forest is an oak-hickory forest on the tabletop of Monte Sano Mountain, but grades into mixed mesophytic forest along the mid-to-lower escarpment. The landscape was delineated into five categories based on underlying bedrock strata. Several measurements were used to analyze the species composition, diameter breast height (DBH) size class structure, and to determine if discrete communities of trees were present. Species composition varied and was a continuum and the forest was diverse by temperate standards. There were some differences in stand structure in the forest on different bedrock strata, as determined by comparisons of DBH size distributions; however, there were no distinct species associations in the forest. This study provides baseline data on species composition and forest structure for a protected and understudied forest in Madison County, Alabama. iv Acknowledgments There are several people without whom the thesis presented here would not be possible. I would like to thank Dr. Robert Lawton who accepted me into the Biology Department, who guided me though this journey, and without his tireless guidance and advice this project would not be possible. I would like to thank Dr. Callie Schweitzer and her team at the United States Forest Service for their critical assistance and knowledge of the forest and how to identify trees and collect scientific data. I would like to thank Dr. Robert Griffin for his advice in all things GIS. v TABLE OF CONTENTS Page Table of Contents ................................................................................................................ vi List of Figures ..................................................................................................................... vii List of Tables ....................................................................................................................... ix Chapter 1 ............................................................................................................................. 1 INTRODUCTION ............................................................................................................... 1 Chapter 2 ............................................................................................................................. 5 LITERATURE REVIEW ....................................................................................................... 5 Chapter 3 ........................................................................................................................... 11 METHODS ...................................................................................................................... 11 Chapter 4 ........................................................................................................................... 19 RESULTS ......................................................................................................................... 19 Chapter 5 ........................................................................................................................... 46 DISCUSSION ................................................................................................................... 46 Appendix ........................................................................................................................... 59 A.

  • 2016-2017 Annual Report
    2016-2017 ANNUAL REPORT 1 Honorable Kay Ivey Governor of Alabama State Capitol Montgomery, AL 36130 Dear Governor Ivey: I am pleased to submit the Department of Conservation and Natural Resources’ Annual Report for Fiscal Year 2016-17. The Department continues to find more efficient ways to communicate and con- duct business with our constituents. License purchases, special hunt registrations and park lodge and camping reservations are available through our websites, www.outdooralabama.com and www.alapark.com. In addition, we are communi- cating to more than half a million people through email newsletters and notices. Funds derived from the cap on sales tax discounts were restored to State Parks in FY 2017. These funds have provided much-needed relief in addressing the back- log of park maintenance projects. Park guests totaled just under 5 million this fiscal year. The federal management of red snapper and other reef fish continues to be a highly volatile issue within the fishing community. Our Marine Resources Division is working with federal agencies and Congress to provide more state oversight of this fishery and a longer season for anglers. Snapper Check, which continued for the fourth year, is an important part of this effort. The State Lands Division has administered the Coastal Impact Assistance Program (CIAP) on behalf of the State of Alabama since its beginning in 2005. During the life of this program, which closed this year, State Lands administered 49 grants for over $58 million funding various coastal project activities supporting Mobile and Baldwin counties. Participation in the state’s Game Check system for the recording and reporting of both deer and turkey harvests became mandatory during the 2016/2017 hunting seasons.

  • North Alabama Sierra Group March 2009 Tuesday Night Mountain Hikes 6:00Pm
    North Alabama Sierra Group March 2009 Tuesday Night Mountain Hikes 6:00pm Meet at the Monte Sano Hiker’s parking lot. Wheeler Wildlife Refuge For the March 19 meeting, we will have a presentation on the Wheeler National Wildlife Refuge, a 35,000 acre refuge established in 1938 to provide habitat for wintering and migrating birds. Considered the easternmost Refuge in the Mississippi flyway, this 34,500 acre Refuge attracts thousands of wintering waterfowl each year and supports the southernmost and Alabama's only significant concentration of wintering Southern James Bay Canada geese. It also serves as winter habitat for the State's largest duck population. Wheeler NWR is comprised of a great diversity of habitat types such as bottomland hardwoods, wetlands, pine uplands, agricultural fields, and backwater embayments. These habitats provide excellent feeding, loafing, and roosting sites for waterfowl, as well as nesting sites for migrating songbirds. The Refuge provides a much needed oasis in one of the fastest growing regions in the state, with Madison being ranked as one of the top ten fasting growing cities in the nation in 2002. There will be no meeting in April. The North Alabama Sierra Club meets at 6:30 the third Thursday of every month at the Huntsville Madison County Public Library in the main auditorium. The library is in downtown Huntsville on Monroe St. just off Governor’s Drive. Everyone is invited. ­ The Editor Paper or Electrons Like everyone else, the Sierra Club is being affected by the downturn in the economy. Donations and membership renewals are down so the national organization has less money to pass on to the local groups.

  • Status of the Flame Chub Hemitremia Flammea in Alabama, USA
    Vol. 12: 87–93, 2010 ENDANGERED SPECIES RESEARCH Published online July 19 doi: 10.3354/esr00283 Endang Species Res OPENPEN ACCESSCCESS Status of the flame chub Hemitremia flammea in Alabama, USA Bruce Stallsmith* Department of Biological Sciences, University of Alabama in Huntsville, Huntsville, Alabama 35899, USA ABSTRACT: The status of many freshwater fish species in the species-rich southeastern United States is surprisingly poorly known. Vulnerable species found in smaller streams in the region have not received adequate research attention. The flame chub Hemitremia flammea (Cyprinidae) is included among a group of stream species considered to be ‘narrow endemics’ susceptible to habitat alterations due to growing human population. The obligatory habitat is spring-fed streams sensitive to human activities. The species has a patchy range primarily in the Tennessee River Valley in Alabama and Tennessee, USA. The conservation status of the flame chub is poorly documented. The NatureServe global status of the flame chub is G3, Vulnerable, and the Alabama state status is S3, Vulnerable. Reflecting the poor knowledge of the species’ status, the International Union for the Con- servation of Nature (IUCN) Red List Category is DD (Data Deficient), a change from an earlier listing of Rare. This study is intended as a presence or absence survey of flame chubs at historic location sites in north Alabama based on holdings records of the University of Alabama Ichthyology Collec- tion in Tuscaloosa, Alabama. Fifty-three sites in 9 counties in the Tennessee River drainage with a historic record of flame chub presence were visited and sampled by seining. One or more flame chubs were found at 18 of these sites.
