unpredictable, and a tree in this range could, against all odds and reason, live <br /> for over a decade. Rationally, the highest hazard trees must be dealt with <br /> right away. <br /> On the other hand, we may select a tree to be pruned and treated, and due to <br /> the unknown nature of the wood fiber formation and scarring history of its <br /> limbs, could potentially have a major failure. In spite of our testing and <br /> analysis, no one can predict the future outcome for these trees for sure. We <br /> can only make recommendations based upon our best professional <br /> judgement using the data collected. <br /> t <br /> fo R4 , ,. 4 - 4 • or replace a tree. ��m:#a t are <br /> I.. <br /> . �y��.� . . , ",nrYrki`L`:;� F. <br /> i * « t�R .o. =. € ,_w.w. ..3.,... <br /> to : ' 4 <br /> Bear in mind that these ISA rating numbers are not absolutes.
