It will be just fine. The Chinese maple that I mentioned earlier this morning sustained surprisingly minimal damage when part of a bay tree fell onto it. The situation initially seemed hopeless prior to the removal the heavy debris that was pressing the diminutive Chinese maple downward. Yet, the little tree somehow regained its composure, and is expected to recover.
The little Chinese maple was always rather sparse in the shade of the surrounding forest. Also, it exhibited an asymmetrically sculptural form. That is likely normal for the species within its natural environment, where it lives as an understory tree (within the shade or partial shade of larger forest trees). The distinctive form and open canopy were part of its allure.
As the debris was removed, most of the stems of the Chinese maple sprang back into their original positions. Only two major limbs were fractured and needed to be pruned away. Some of the minor twiggy growth was groomed in the process. The main trunk was somewhat destabilized, but not too detrimentally so.
It probably should be no surprise that the little tree was so resilient to the altercation. It is, after all, an understory tree. Within its natural environment, it likely contends with the same sort of abuse. Chinese forests are likely just as messy as forests here are. Gravity pulls all that mess in the same direction.
The little Chines maple may not look like much now that it has been groomed and pruned to be even more sparse than it originally was, but it should be fine. By this time next year, foliar density should be comparable to what it was prior to the incident. The form will remain sculptural, as it grows away from the shade of the forest, and out over the stream below.
