Using sample forms based on the Tree Care Standard, our group of forty strong wrote specs to manage challenging scenarios. The A300 format literally keeps administrators, staff, and contractors all on the same page!

November 4, 2013: Retrenching Hollow Trees for Life at the New England ISA Chapter, Warwick RI
Hollowness occurs naturally, as taproots and heartwood are shed. Buttresses and adaptive growth provide needed support. Formulas for tree structure devaluation ignore strengths and dwell on defects. Interior trunk decay is the reason for many tree removals, but trunk failures are rare. We focus on the flare, the forks, and the living tree.
Branch reduction is often avoided because arborists are always told that removal cuts are better for the tree, and heading cuts are bad. But outer branches are naturally shed as trees age, leaving an inner crown. Retrenchment pruning of big hollow trees is responsible risk management, reaching beyond rules of thumb and arborphobic myths.
Even clients with low risk tolerance are willing to retain hollow trees that are conservatively managed. Witness rejuvenation, in retrenched residential and municipal trees. New growth arises from the right places, and the tree lives on.
