Unformatted text preview: ESM 242: Notes on Reserve Selection and Conservation Planning 1 0.1 Problem Setup Since 1951 the Nature Conservancy (among other conservation organizations worldwide) has engaged in conservation of biological diversity through land acquisition and/or management. TNC has protected over 100 million acres (about the size of California) worldwide (16 million in US, 90 or so million in ROW). TNC’s mision is: “To preserve the plants, animals, and diversity of life on Earth by protecting the lands and waters they need to survive”. Our goal is to learn how to help design a reserve network that maximizes a biological objective subject to a budget constraint. We may or may not have complete data. Often objectives given by conservation organizations are not well-specified. This exercise (and most others we have engaged in in this course) point to the need to formulate a well-specified performance measure . What does this mean? • For any 2 “candidate” solutions, you need a measure that tells you how well one does versus the other. • This implies that you also have a well-specified objective. An example is “maximize species coverage subject to a budget constraint”. For any reserve design that fits within the budget (this is a “candidate solution”), we can determine the number of species covered....
