Basic Data Entry—Boundary Waters Canoe Area These data are from an area in northern Minnesota that experienced a severe blowdown event in the late ‘90s. The data are part of the basic information for a fuels analysis problem used in Technical Fire Management. Until recently, crown data were available only for tree species common in the western states. Analyses had to use “surrogate” species—those for which necessary data were available that resembled the desired species. For example, lodgepole pine was used as a surrogate for jack pine; subalpine fire as a surrogate for balsam fir. Version 3.0 of FMAPlus® has added data for many of these non-western species. They can be selected using the Preferences choice under the File menu in CrownMass®. Enter the data in the table below, and answer the questions. Use defaults for Proportion in Crown and Surface Deposition Remaining. Be sure to check the desired species in the Preferences dropdown.
