Nonnative invasive plants are altering ecosystems around the world with alarming speed. They outcompete native plants and ultimately change the composition and function of the ecosystems they invade. This poses a particular problem in wilderness and other natural areas that are set aside to maintain natural conditions. Wilderness managers are not only faced with the challenges of preventing and identifying new invasions, but they also must decide between allowing the unfettered existence and spread of invasive plants and using control strategies that can have unintended consequences. This reading list summarizes approximately 250 books and articles and 25 online resources that provide context for making these management decisions. The first major section examines issues specifically related to invasive plants in wilderness and other natural areas. The second section provides background information about invasive plant ecology, ranging from the factors that contribute to plant invasions to understanding the many effects invasive plants can have on species, communities, and ecosystems. The final section focuses on managing these species, including management planning, ways of preventing, predicting, and finding new invasions, and developing and prioritizing control and eradication strategies. While literature related to understanding and managing specific invasive plant species has been aggregated elsewhere, this document presents an organized framework of literature that addresses concepts pertinent to management.
