In a recently released book, Harvard Forest researcher Robert McDonald co-authored a chapter on the causes and consequences of land-use change in the North Carolina Piedmont with D.L. Urban, E.S. Minor, and E.A. Treml. The project integrated studies of forest dynamics, conservation value (forest songbird communities), and ecosystem processes (watershed hydrology and biogeochemistry). As part of this modeling effort, they estimated the uncertainties due to errors in imagery and ground data, model selection, parameter estimation, and process error.
