| Indicator Species | ||
| Black Oak (Quercus velutina) | ||
 |
Black oak is the dominant tree of southern Ontario savannas, and grows in characteristic open stands in full sunlight. A small tree, it can reach 20m in height. As the name implies, the bark is almost black in colour and deeply furrowed into squarish ridges. Black oak hybridizes with red and pin oak and so its characteristics are variable. The 15 cm long leaves are shiny dark green above and yellowish-brown below with tiny hairs along the veins. There are five to seven lobes that end in sharp bristles while the lobes are separated by deep U-shaped notches. The acorns are small, 12-20mm long, with a thin, scaley cap that covers about half of the nut. Acorns are an important food for many small mammals, especially rodents. | |
