Is it a tree worth saving, a battle worth fighting?
With this information on the effects of varying depths and textures of fill soil, varying textures and structures of base soils, and a tree’s relative tolerance to changes, the next step should be a determination of whether the tree or trees in question are worthy of preservation and protection tactics. Diseased or dying trees should be removed simply because the chances of a tree in that condition surviving are slight. Removing those trees would open up space for new trees after the filling operation is over. However, if the tree is relatively healthy and is a key element in the appearance and function of the landscape, and if money is not an issue, then all necessary steps to save the tree may be taken. As a general rule, it is cheaper and more effective in the long run to prevent damage from initially taking place. Research has shown that little success can be expected by removing fill that has been present around the tree for more than two years (Cue et al., 2002). The initial cost
