The Role of Data and Inference in the Development and Application of Ecological Site Concepts and State-and-Transition Models

Abstract

On the Ground • Information embodied in ecological site descriptions and their state-and-transition models is crucial to effective land management, and as such is needed now. • There is not time (or money) to employ a traditional research-based approach (i.e., inductive/deductive, hypothesis driven inference) to address the unknowns in developing and documenting ecological site concepts. • We propose that the development of ecological site products is a dynamic task of defining concepts and processes that best explain the available data (i.e., abductive reasoning), and as such a more iterative approach to their development is needed than is currently used. • Under the proposed approach, ecological site concepts are never viewed as final but only the best representation that is supported by available knowledge and data. • The natural result of this way of thinking is that products like ecological site descriptions and state-and-transition models should continually be tested and improved as new data become available.
