The classic and trusted book “Fifty Common Trees of Indiana” by T.E. Shaw was\u00a0published in 1956 as a user-friendly guide to local species.\u00a0\u00a0Nearly 70 years later, the publication has\u00a0been updated through a joint effort by the Purdue Department of Forestry and Natural Resources,\u00a0Indiana 4-H<\/a>, and\u00a0the\u00a0Indiana Department of Natural Resources<\/a>, and reintroduced as “An Introduction to Trees of Indiana.”<\/p>\n

The\u00a0full publication<\/a>\u00a0is available for download for $7 in the Purdue Extension Education Store. The field guide helps identify common Indiana woodlot trees.<\/p>\n

\"Large<\/a>Each week, the Intro to\u00a0Trees of Indiana web\u00a0series will offer a sneak peek at one species from the book, paired with an\u00a0ID That Tree video from Purdue Extension forester\u00a0Lenny Farlee<\/a>\u00a0to help visualize each species as it stands in the woods.\u00a0Threats to species\u00a0health\u00a0as well as\u00a0also\u00a0insight into the wood provided by the species, will be provided\u00a0through additional resources as well as the\u00a0Hardwoods of the Central Midwest<\/a>\u00a0exhibit of the Purdue Arboretum, if available.<\/p>\n

This week, we\u00a0introduce the quaking\u00a0aspen or\u00a0populus tremuloides<\/em>.<\/p>\n

The quaking aspen, also known as the trembling aspen, is adaptable to a variety of soils, ranging from moist loamy sands and clay, but it is shade intolerant. It is often found on the edge of woodlands or where the site has been disturbed, giving it access to full sunlight.<\/p>\n

This species is identifiable by its whitish to grayish bark with dark spots where the branches come out of the trunk. It has small rounded leaves with very small teeth along the margin. Like most aspens, it has long flat leaf steams that are known to flutter in the wind.<\/p>\n

Quaking aspen is found int he northern part of the state of Indiana. This species is found from Nefoundland through Alaska in the West, and as far south as Arizona. In the Midwest, it ranges south to northeastern Iowa, northern Illinois and Pennsylvania. It is also found in some scattered areas in the Appalachian Mountains. It is the most widely distributed tree in the United States.<\/p>\n

According to the\u00a0Hardwood Lumber and Veneer Series<\/a>, aspen is one of our lightest woods with a 12 percent moisture content and a weight of 26 to 27 pounds per cubic foot. It was at one time relegated to the pulp and paper industry as a weed tree, however it is now a favored species for the manufacturer of panel boards.<\/p>\n
