REGULAR D4EETING OF THE ORONO COUPJCIL, AUGUST 29 , 1978 Page 21 <br /> I have discussed the shade tree e1M with the TREE DISEASE PROGRA <br /> Council preceeding the 1978 season, and they were (Continued) <br /> in agreement that the wooded or forested trees <br /> need not be pursued. I would like this discussed <br /> again and hopefully voted into program policy. <br /> The exact definition of a shade tree is one that <br /> provides shade to a home within a lawn area. The <br /> forest tree is in a non-maintained area, usually <br /> heavily wooded but not necessarily. <br /> Diseased Tree Disposal Problems in Orono <br /> In the last several years , many meetings have <br /> been a�tended on the disposal of diseased elm <br /> trees. To date,no solutions have been reached. <br /> Present disposal sites are disappearing and others <br /> are L?nder increasing restriction. Costs per load <br /> are increasing rapidly. At the present rate, it <br /> is possible there could be no sites available at <br /> all within a couple of years. <br /> Utilization of diseased trees has failed miserably. <br /> Shade trees do not have the upright straight form <br /> desirable for lumber, have considerable r.�etal and <br /> concrete in tzzem, and chipping for cor.imercial use <br /> has very limited market. Forget utilization in <br /> this form, as it will solve only a small percentage <br /> of the available diseased trees waiting to be <br /> disposed of. <br /> If there are no disposal sites, what do we do? <br /> The best solution might be to let residents retain <br /> the wood for heating purposes. This could be done <br /> in several ways: <br /> 1. Untreated elm wood retained withDut consideration <br /> of increasing bark beetles populations carrying <br /> spores of Dutch elm disease. This would undoubt- <br /> edly increase the incidence of the disease, but <br /> does it matter if the bulk of the elms are lost <br /> in eight or twelve years? <br /> 2. Elm wood treated with 0.25o Penta Cloro Phenol, <br /> a wood preservative that has both a repelling <br /> action against the bark beetles, and acts as <br /> an insecticide. The rate is extremely low, and � <br /> apparently presents no biological probler►. <br /> Application would have to be by a licensed <br /> Pesticide Applicator. <br /> 3. Homeowner burning of the diseased wood. P.C.A. <br /> has restrictions on this , but if the residents <br /> have no disposal sites to haul the wood to, they <br /> are in violation of State Statutes anyway. Thus <br /> they break the law no matter what they do. <br /> (Continued) <br />
