We estimated length of leaders of current annual growth for feltleaf willow from their diameter at the bud scale scar using regression equations developed for this crushed area by Bowyer et al.
In that analysis, diameter of current annual growth was the dependent variable, with location on the twig (at the bud scale scar or bite) where diameter was measured, previous browsing history (browsed or unbrowsed), and their interaction as main effects.
