JOYCE KILMER WROTE ABOUT TREES.  MOST OF US CAN REMEMBER A FAVORITE SHADE TREE OR CLIMBING TREE.  MICHIGAN HAS SOME OF THE MOST DIVERSE FORESTS IN THE COUNTRY. MAPLE, BIRCH AND BEECH TREES HAVE INCREASED BY NEARLY A MILLION ACRES BETWEEN 1980 AND 1993. MICHIGAN IS REGAINING MANY OF THE TREES LOST TO FIRES AND LOGGING IN THE NINETEENTH CENTURY, AND ANNUAL GROWTH IS INCREASING.  AS WE SEE HIGHWAYS AND BUILDING DEVELOPMENTS GO IN, IT SEEMS IMPOSSIBLE, BUT WE ARE GETTING MORE TREES. THIS IS A PLUS FOR MICHIGAN, BECAUSE TREES ACT AS A CLEANSER FOR THE ENVIRONMENT.  I WONDER IF THE EPA WILL NOTICE WHEN THE NEW TAILPIPE REGULATIONS COME UP.  SPRING IS TREE PLANTING TIME.  HAVE YOU REALLY ENJOYED A TREE LATELY?
