This list of habitats is admittedly not complete for the 

 regions visited^ but is intended to inckide those which we 

 studied. W'e had no opportunity of studying either the shores 

 of a large river or jack pine ridges, both of which situations 

 will undoubtedlyn have habitats iipt here recognized. , ^-^ n 



the habitats st udied in Gogebic ''and 'Unto i iagon counties ' 



but every habitat has been listed which seems to form a dis- 

 tinct type of mammal environment. We are firmly convinced 

 that it is better to describe a great number of habitats rather 

 than to lump different kinds of environments together. It is 

 infinitely easier for a later w^orker to combine several habitats, 

 which have been split too finely, than it is to separate the com- 

 ponent habitats which may have been Itimped together under 

 one name. 



No attempt is made to give complete lists of the plants 

 found in each habitat, but only the more conspicuous plants 

 or those of special importance to the mammals are mentioned. 

 The plant names vised are mostly taken from Darlington's list 

 of Gogebic County plants.^ 



Exposed Shores 

 Opcn-zvater habitat: This habitat includes the areas of open 

 water with no rooted vegetation in the deeper parts of the 

 lakes and rivers. On Lake Superior at Little Girl's Point this
