SPECIES DISTRIBUTION - RANGE MAPS

   Distribution of tree species across the Upper Peninsula varies.  Most species can probably be found in every county.  However, not all species are necessarily components of a forest stand.  These distribution maps disregard occasional occurrences or individual trees in parks, towns, or other "artificial" locations.  The distribution is shown in orange.  To see species listed by county and abundance, click HERE. There's also a helpful website that shows tree ranges in their entiretly, click here.
   The source for these maps was primarily from the U.S. Forest Service's Forest Inventory and Analysis (FIA) reports.  Results from annualized forest inventory can be downloaded from the U.S. Forest Service Forest Inventory and Analysis Unit. The survey has specific definitions of what qualifies as "forest".  Only tree species that occur under that definition are included.  Of course, the sampling was not as intensive as some kinds of inventory and it is entirely possible that occurrence of a fairly uncommon species may have been missed.  The are populations of tree species in U.P. locations that are not reflected in the USFS data. Examples include substantial amounts of northern pin oak in Menominee County and boxelder in every county.
