The Indiana Department of Natural Resources (DNR) needs the public’s help to update The Big Tree Registry, a list of the largest known specimen of each native tree species in Indiana. “Indiana’s currently tallest recorded tree is a 152-foot-tall bitternut hickory, and our widest tree circumference is a silver maple at more than 361 inches,” said Jacob Roos, DNR urban forestry director. “We need help getting out across the state to find our new record-setting trees.” DNR says it’s time to review the recently updated champions list and start looking for new candidates to nominate for the list, which is maintained by DNR’s Division of Forestry.
