Trees

The shares are four grades, from “in its own places” to “most of the forest”, rather than measured proportions. The weeks were measured at Harvard Forest for ten trees; the record’s words supply the rest. Beyond the maple country the weeks move by a rule until observations replace it, except where a source gives a local window. Where the weeks were measured, gray begins around the observed days when half the leaves had fallen; it does not mean every leaf was gone. This year’s mark is Autumn Guide’s model of the regional forest state, beside the reports with their dates; it is never an estimate for an individual tree.
