Study Title: Monitoring Trail Usage in National Parks 16. Abstract This study evaluated commercially‐available trail counters, developed a step‐by‐step framework for monitoring trails and other non‐motorized facilities, and applied the monitoring framework in two unique park settings. The Mission Reach Trail in the San Antonio Missions National Historical Park served as an example of a typical linear urban park. The Guadalupe Mountains National Park served as an example of a rural park with a trail network and a limited number of discrete access points. Trail use was sampled at several locations within these two parks, and overall estimates of trail use were developed from this data collection. The resulting trail use data quantifies how many people use the trails at different times during the day, different days of the week, and months of the year. This trail use data can be used for several purposes, such as managing natural resources, planning or developing new programs and facilities, and quantifying the public health and physical activity benefits to park visitors. 17.

In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly ac- quired facts in the fields of Anthropology, Biology, Geology, History, and Technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the different subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902 papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium.

Dissertation Presented to the Faculty of the Graduate School of the University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin May 2007 Acknowledgements While there are many people deserving of recognition for their assistance and support during the process of completing this research, I can mention here only a few. First, without a doubt, I would like to thank Irene for her love and support over the years, and without whom this process might never have started, and certainly would not have ended. I thank my mother, Marilyn Chumley, for her love and support as well, especially after the death of my father, Don Chumley; I trust that he would be proud of this accomplishment. My advisor, Dr. Robert K. Jansen and my cohort of labmates deserve mention for providing a fun and challenging environment. Jan Barber, Romey Haberle, Barbara Goodson, and Micheal J. Moore all provided excellent advice, discussion or feedback in the lab or field. Everyone who went into the field with me needs a special award, particularly if the Land Cruiser decided to break down on that particular trip; Geoff Denny gets kudos for the Monterrey experience, when we, like an old submarine, ran only on batteries, and Mike gets some kudos for the Deerslayer episode, and the many, many beers and many, many miles, usually not at the same time of course.

Worthington, Ph.D. Floristic Inventories of the Southwest Program P. O. Box 13331 El Paso, Texas 79913 El Paso, Texas March, 2002 INVENTORY OF THE FLORA OF THE GUADALUPE MOUNTAINS, NEW MEXICO AND TEXAS INTRODUCTION This report is a second working draft of the inventory of the flora of the Guadalupe Mountains, Eddy and Otero Cos., New Mexico and Culberson Co., Texas. I have drawn on inventory work I have done in the Sitting Bull Falls and Last Chance Canyon area of the mountains and a survey project at Manzanita Springs carried out over the past several years as well as collections made during survey work on two projects completed in 1999 (Worthington 1999a, 1999b). I have included in this report a review of almost all of the literature that deals with the flora of the study area. The goals of this project are to provide as nearly a complete inventory as possible of the flora of the Guadalupe Mts. which includes cryptogams (lichens, mosses, liverworts), to provide a nearly complete review of the literature that references the study area flora, to document where the voucher specimens are located, and to reconstruct a history of collecting efforts made in the region. Each of these activities demands a certain amount of time. Several more years of field work are contemplated. On-line resources have yet to be evaluated. The compiler of this report welcomes any assistance especially in the form of additions and corrections.
