The Emerald Ash Borer is an environmental disaster, especially in urban areas where the ash tree was widely planted on city streets as replacement for the elm trees lost to the Dutch elm disease four decades ago. Cities are struggling to remove dead trees from city right-of-ways and parks. To give a sense of the magnitude of the problem officials of the City of Ann Arbor proposed a two year millage to raise four million dollars to pay for removal of over 10,000 city ash trees. The voters turned the tax proposal down in a recent election. The City will have to find other funds to pay for the removal and more time will be needed to complete the job.
Dead ash trees on private property are
problems for the individual homeowner. This photo essay is a record
of one homeowner’s approach to the problem. His seventy foot tall
white ash tree with a three foot diameter trunk seemed perfectly healthy
in 2004 but was clearly dead by spring of 2005 and had to be removed.
Estimates for the cost of removal were $2500 and $2000. Instead he
took the matter into his own hands. He rented a cherry picker for
one day ($500) and a wood chipper for a few hours ($150). He and
his brother-in-law cut the tree down. He hauled the felled wood and chips
to the Ann Arbor Recycling Center for disposal. This site was an
official disposal site for Washtenaw County in which Ann Arbor is located.
Washtenaw is one of the quarantined counties in southeast Michigan where
ash tree wood and waste can be left free of charge. Unfortunately
despite being an excellent hardwood (baseball bats are made of ash wood)
the infested wood cannot be salvaged for any purpose. The quarantine
particularly prohibits shipping fire wood out of the quarantined counties.
On the left, Ann Arbor parks now have many dead ash trees which have opened the canopy of the forest with possible detrimental effects on the ponds and pond life. |

Experience and initiative pay off. The homeowner was experienced in running a cherry picker and his brother-in-law had experience cutting trees. The two man crew felled the tree in one day. Sawing of big limbs and the trunk took several days and cost extra to rent big chain saws. |

It was a splendid effort but at the same time a tragedy. A beautiful ash tree is gone, one of many thousands in the city and millions across the region, victims of our global society. |
