East Bethany, New York, is located in the western part of New York state. The U.S. Department of Agriculture hardiness zone for the city ranges from 5 to 6 with average minimum temperatures of -20 to 0 degrees F. Trees native to Bethany, include the tamarack, black walnut and the eastern cottonwood, according to the New York Flora Atlas.
The tamarack is a larch and a member of the pine family. Also called the Eastern larch, the tree is found in swamps, lake shores and on mountainsides. The tamarack is the only Eastern native conifer with deciduous, needle-like leaves that grow in clusters that radiate around the branch. The tamarack is narrow and thin and ranges in height from 40 to 80 feet with a trunk diameter of 1 to 2 feet, according to the "Field Guide to Trees of North America," by the National Wildlife Federation. The bark is pink-orange and flakes into circular scales. The needles turn yellow in autumn before falling from the tree. The purple-red cones are shaped like eggs and turn brown when mature.
The black walnut tree is medium- to large-sized, ranging in height from 70 to 90 feet with a diameter of 2 to 4 feet. Prized for its timber, the deep brown heartwood is used for cabinet-making. The bark is smooth when young, turning dark gray-brown to ashy gray in color and deeply grooved when mature. The leaves are spear-shaped and dark green, turning yellow in the fall. The nuts are covered by a thick green husk that decays to reveal the nut's hard shell. Both the male and female flowers are catkin-like and bloom separately on the same tree, according to the "Illustrated Encyclopedia of Trees of the World," by Tony Russell, Catherine Cutler and Martin Walters.
The Eastern cottonwood, also called the Carolina poplar and the Southern cottonwood, ranges in height from 36 to 190 feet with a trunk diameter of up to 6 feet, according to the U.S. Department of Agriculture Forest Service. The Eastern cottonwood has a tall, straight form when found in stands, which are groups of trees. When growing in the open, the trunk of the tree is broad and heavily branched. The bark is pale green on young trees, turning gray and deeply grooved as the tree matures. The green leaves are triangle-shaped and rustle loudly in the breeze, turning yellow in the fall. The flowers bloom in the spring as catkins, which are reddish-brown in the color.
