While serving in Bulgaria, he kept me connected to the home front and provided invaluable words of wisdom. Since my return Blair has made sure I kept on track with what once seemed an insurmountable task, completing my masters. I would also like to thank the remainder of my committee; Peg Gale for giving me the opportunity to broaden my horizons by assisting her in a wetlands study and for always giving an encouraging smile and kind words; Jim Pickens for providing some friendly advice or a humorous story when I needed to hear something uplifting; and to Ron Gratz, for his valuable suggestions and for understanding and supporting the Peace Corps experience. Thank you all for your support, time, and critiques. A warm thank you to Janet Locatelli, a resourceful librarian, for finding some obscure information that I had lost hope of ever finding. Bulgaria is a beautiful country with warm people and a diverse environment. My service in Peace Corps would not have been as enjoyable or as rewarding without my friends there. I would especially like to thank Silvia, Ivanka, and Stephen Angelova, our Bulgarian family, for their constant support and generosity. I will always cherish our friendship and remember the daily acts of kindness you gave. Special thanks to Ani and Gergana for their friendship. This study would not have been possible without the Peace Corps Volunteers that administered the surveys, and the Peace Corps Bulgaria office for their assistance. Many thanks! Lastly, I would like to thank my family. All of you have contributed with your love and support. Thank you Mom, for supporting me throughout college and life, and for teaching me how important it is to enjoy whatever I choose to do. Larry and Denise, thank you for your editing skills and all of your support. Special thanks to Jeff, for loving Peace Corps and Bulgaria as much as I do, looking forward to our next adventure together, and for sharing the grueling process of writing a thesis with me. viii ABSTRACT Bulgaria is a country rich in history, culture and traditions which include the use of herbs. Herbs are commonly used throughout Bulgaria for medicinal purposes, in the preparation of food, and as decoration. Bulgaria is a country in political, economic, and cultural transition. Many privatized herb companies opened after the fall of communism; a high unemployment rate led to a larger available work force for collecting. Bulgaria is currently the largest exporter of herbs in Europe. Herbs play an integral part in the Bulgarian household. I decided to design an ethnobotanical study to learn which herbs are used, how they are used, and the methods used to acquire them. I also wanted to learn if the local people believe herbs are threatened, and if they do, what are those threats? To accomplish these goals, I designed a multiple choice format survey, listing 128 herbs and short answer questions, that would be administered by other Peace Corps Volunteers. In this way a wide range of towns throughout Bulgaria could be surveyed. Nineteen towns were surveyed. The responses indicate that herbs are primarily used medicinally and in the preparation of food. The people surveyed indicated that herbs play an important role in their families and that Bulgarians are knowledgeable on various uses of herbs, traditional and modern. The responses also indicated that Bulgarians are concerned about the abundance of herbs because of problems associated with herb companies, improper gathering techniques, pollution, and deforestation. Results from the nineteen towns surveyed show that fifteen herbs are commonly used in Bulgaria. These herbs are primarily popular medicinal species or are commonly ix used in traditional Bulgarian cuisine. These herbs usually have a widespread natural range or can be easily cultivated and are readily available
