If not find someone with the expertise to answer the questions. Then.if the answer to questions la. lb and lc are all NO, contact the Natural Heritage program of DNR. la.Human caused disturbances. Is there significant evidence of human-caused changes to topography or hydrology of the wetland as indicated by any of the following conditions? Consider only changes that may have taken place in the last 5 decades. The impacts of changes done earlier have probably been stabilized and the wetland ecosystem will be close to reaching some new equilibrium that may represent a high quality wetland. 1 al.

Connection to other habitat areas: Select the description which best matches the site being evaluated. -Is the wetland connected to,or part of,a riparian corridor at least 100'wide connecting two or more wetlands;or,is there an upland connection present>100' wide with good forest or shrub cover (>25%cover)connecting it with a Significant Habitat Area? YES -Is the wetland connected to any other Habitat Area with either 1)a forested/shrub corridor< 100'wide,or 2) a a corridor that is> 100'wide,but has a low vegetative cover less than 6 feet in height?
