| Depending on the species of tree, bark has different characteristics and functions. It provides trees with essential structural support, conducts nutrients from the leaves down to the roots, and offers protection from wood-boring insects and twig-gnawing mammals. In some cases, however, the bark itself becomes a food source, attracting animals such as porcupines which feed on the bark during the winter. |
| All trees have bark of some form and color. Some is smooth and shiny or papery, some is rough, thick and ridged. The variety of bark coloration is as diverse as its textures--tree trunks come in every shade from light silvery-white to deep orange-brown. |
