Identifying Features of Oaks
Oaks are deciduous trees that can grow up to 100 feet tall with a trunk diameter of up to 6 feet. They have lobed leaves that vary in shape depending on the species. The bark of mature oaks is thick, rough, and deeply furrowed. Oaks produce acorns that can vary in size and shape depending on the species.
The red oak is easily identified by its dark, chestnut brown winter buds and pointed lobes. The black oak has a dark, scaly bark and deeply lobed leaves with bristle-tipped lobes. The white oak has smooth, light gray bark and rounded lobes. The pin oak has deep, narrow sinuses and bristle-tipped lobes. The scarlet oak has shiny, dark green leaves with pointed lobes and a bright red fall color. The swamp white oak has rounded lobes and a grayish-white bark with deep furrows.

Growth Conditions and Soil Types
Oak trees are found in a variety of habitats throughout New York State and the eastern United States. They are typically found in well-drained soils, including sandy soils, and are often associated with the Adirondack Section, Alleghany River, and Genesee and Alleghany Rivers. Oak trees require full sun to grow and thrive, and can tolerate a wide range of soil pH levels.
Oak Trees and Wildlife
Oak trees are an important component of forest ecosystems in North America, providing food and habitat for a wide variety of wildlife species. They are particularly important for supporting Lepidopteran species, which rely on oak trees as a food source. In addition to supporting wildlife, oak trees also play an important role in nutrient cycling and soil health, helping to maintain healthy forest ecosystems.
Oak trees are susceptible to a variety of pests, including the oak wilt fungus and the gypsy moth. These pests can cause significant damage to oak trees, and can lead to the decline and death of individual trees and entire stands. Despite these challenges, oak trees remain an important component of forest ecosystems in New York State and throughout the eastern United States.
