The general information and specific management guidelines presented are based on best available science, peer-reviewed l l expert opinion, and published literature.

At the core of PARC is the philosophy that we all must work togeth- er. There is no “us versus them.” It is all “us.” This pub- lication is the product of extensive efforts of many peo- ple and contains the contributions of many individuals from academic, private, government, and industrial backgrounds.
