OUt- pt-imat-y objective was to identi~y b-ee <br />species composition and determine the overall health o~ the <br />trees" We also discussed tree removal for a drainage system <br />and ~actors to consider when doing this. <br />The overall health of the trees is very good" The stand <br />consists of mostly oak with some understory trees including <br />elm, ash, bOl-:elder, maple, aspen, and chen'y. The n;)d oak <br />a~'e qLlite matLlt"E" and compose most of the canopy" r I~OL.lld <br />estimate that about 60% of the b"ees at-e bLtr oak, :;0% at"e <br />tOed oak, and 10% of mil<ed tn~e species. Thet"e WeH"e a fe~w <br />small pockets o'F dead b"ees that have been dead fot" ",tlme <br />time indicating the dieback was probably a result of <br />dt"ought/lnsec:t damage. The lat"gest at'ea with mot"tallty was <br />on the fat.. w,",st side of the wetland along the slope. This <br />also had been dead for some time and looked more like <br />drought and/or two-lined chestnut borer damage than anything <br />else. Overall, the stand looked fairly healthy. There was no <br />oak wilt obsE'wved on this pt"opet"ty. The~-e is a sm,.l1 oak <br />wilt in~ection centet" just.
