How to identify witch-hazel (Hamamelis virginiana) | TREE ID #12

My tips for tree identification RECOMMENDED FIELD GUIDES -Trees of the Eastern and Central United States and Canada, by William M. Harlow -The Tree Identification Book, by George W.D. Symonds LEAF ARRANGEMENT -Alternate: leaves grow one and then the other along the direction of growth -Opposite: leaves grow immediately across from each other, e.g. families, Maple, Ash, Dogwood, Buckeye (“MADBuck”) -Whorled: leaves radiate out from stem or branch at a single point, e.g. Catalpa -Hint: the growth pattern shows up with twigs, too LEAF SHAPE -Needles (pines) or broad leaves (maples) -Are leaves simple (cherry) or compound (ash) -Leaf edges can be smooth, serrate, and/or lobed FLOWERS, FRUITS, SEED -Sketch seasonal growths on the tree such as clusters of male flowers (catkins), cones, and seeds with wings (samaras) BARK -Note color and texture, but be aware that these traits can change with age -Using only bark for tree identification can prove unreliable WHY IS TREE ID IMPORTANT? -Knowing which trees are growing on a site can tell us about the soil, climate and other environmental conditions there. -Certain trees make good lumber, paper, medicines, and food that people need. -Some animals depend on particular trees for food or shelter. -Certain plants and mushrooms in a forest may grow best when near other types of trees. -Sometimes trees from other areas become invasive and need to be removed.
