NORTHPORT, Michigan – Old-growth white pines and century-old hemlocks surround the shoreline at Kehl Lake near the tip of the Leelanau Peninsula, the latest woodsy spot in Michigan to gain a special forestry recognition. Nonprofit Leelanau Conservancy last week enrolled its Kehl Lake Natural Area into the Old-Growth Forest Network and celebrated with a guided one-mile hike on Sept. 25 at the 279-acre protected wetlands and forest. The site is the second in Leelanau County to be registered in the nationwide network under the condition of no future commercial logging. …The natural area near the Lake Michigan shoreline is an important wildlife corridor as a valuable habitat refuge along a critical migratory bird flyway. There are two miles of trails for visitors and a viewing platform at a marshland for watching waterfowl and songbirds.
