NRM 3307 1-19 What is conservation science? Goal: long term conservation of biological diversity = conservation of rare, endangered, or threatened species the application of scientific principles and knowledge to conservation problems a multidisciplinary science that has developed to deal with the crisis of declining biological diversity a sub-discipline of biology that draws on genetics, ecology and other fields to find practical ways to save species from extinction and preserve natural habitat Conservation vs. Natural Resource Management similar but: Utilitarian economic objectives are typically dominant conservation focuses on a much broader section Objectives/Methods understand the effects of human activities on species, communities, and ecosystems develop practical approaches to preventing the extinction of species and if possible reintegrate endangered species into a properly functioning ecosystem manage wild land ecosystems Guiding Principles 1. Evolution is basic axiom that unites all of biology 2. The ecological world is dynamic and largely non-equilibrium 3. The human presence must be included in conservation planning Characteristics a crisis discipline because of this, and unlike most disciplines the problems we deal with are often “chosen for us”

our job is to respond to the need-often before all the facts are know evolutionary time scale an inexact science-often value laden Crisis rapid response we believe that polar bears are being threatened by global climate change it’s always tempting (and usually correct) to say: “we just don’t know enough now we need to study the problem further” recommending further study is equivalent to deciding that current practices will not doom it to extinction in the mean time deciding to recommend further study is a management decision, it is a decision that if there is a problem we can still correct it later Precautionary Principle a response to uncertainty acting to avoid serious or irreversible potential harm, despite lack of absolute scientific certainty as to the likelihood, magnitude, or causation of that harm 1-21 Who does Conservation biology?
