TNC has protected over 100 million acres (about the size of California) worldwide (16 million in US, 90 or so million in ROW). TNCs 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....
