Southern flying squirrels (SFS) (Glaucomys volans) were studied using telemetry to investigate den tree characteristics and to estimate home range sizes in the Huron-Manistee National forest in the northwest corner of Newayo Co, Michigan. Eight SFS were successfully radio collared, with a resulting average home range size of 7.88 ha (+ 2.91 SE). Den trees had significantly larger average diameter at breast height (dbh) than random trees (P<0.001), and squirrels showed a preference for sugar maples (Acer saccharum) over other available tree species. These findings provide important information for the management of SFS habitat by indicating the need for larger trees that can be used as den trees.
