A list of tree species, grouped generally by biogeographic realm and specifically by bioregions, and shade tolerance. Shade-tolerant species are species that are able to thrive in the shade, and in the presence of natural competition by other plants.
A branch collar on a common oak (Quercus robur L.). Tree branches are attached to the trunk with a series of trunk collars that annually envelope the branch collar.
