Mis-mapping of Boreal Acid Peatlands and Laurentian Acadian Alkaline Conifer-Hardwood Swamps

[Megan Sebasky]

Hi all,

During the Milwaukee fuels calibration, it was brought to our attention that there are mapping issues with two of the EVTs we were reviewing (which are in the top 10 burnable fuels by acreage in the Lake States). In a previous fuel calibration in the Hiawatha National Forest, a "mask" was used to correct for the mis-mapping of these two EVTs based on local vegetation data. In order to implement a mapping "fix" in the Northeast-Midwest risk assessment, we would need a mask that applied to all three Great Lakes states. It was thought that a soil acidity (pH) spatial layer might do the trick. Unfortunately, we were not able to find any supplemental datasets that we could confidently create a mask from. For more information, see story 1 and then story 2, available on our Google Drive, here - https://drive.google.com/open?id=1UK0wnjohFx-mhlhqRhjn3KvG6N6blLho

If you have any ideas on other analyses to run, or patterns we missed in the data presented, please let us know!
