The classic and trusted book “Fifty Common Trees of Indiana” by T.E. Shaw was published in 1956 as a user-friendly guide to local species.  Nearly 70 years later, the publication has been updated through a joint effort by the Purdue Department of Forestry and Natural Resources, Indiana 4-H, and the Indiana Department of Natural Resources, and reintroduced as “An Introduction to Trees of Indiana.”

The full publication is available for download for $7 in the Purdue Extension Education Store. The field guide helps identify common Indiana woodlot trees.

Each week, the Intro to Trees of Indiana web series will offer a sneak peek at one species from the book, paired with an ID That Tree video from Purdue Extension forester Lenny Farlee to help visualize each species as it stands in the woods. Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available.

This week, we introduce the basswood or Tilia Americana.

The American basswood, which is also called linden, is commonly identified by its simple heart-shaped leaves with finely toothed margins, flat bark with long running lines up and down the trees, and possibly a ring of sprouts originating from the base of the tree. The clusters of small, nutlike seeds (⅓-inch in diameter)
are attached by a stem to a leaflike wing.

This species is often found on moist sites, deep, loamy soils, with its range stretching from the Great Plains east and from southern Canada through northern Arkansas, Kentucky and the mountains of North Carolina and Tennessee.

With heights reaching 70 to 80 feet tall, basswood can offer good shade. It also offers good flowering for bees. This species has a light colored, fine-grained wood varying from a white color to a very light brown or flesh color.

Due to its weight and stability, basswood has historically been used to make Venetian blinds and key stock in pianos. It also is a preferred species for carving, including items like hunting decoys, etc.

Spring is in full bloom and trees are beginning to look green again. Learning how to identify trees in yards, neighborhoods and local parks provides insight into the diversity and relationships found in nature. Lenny Farlee, Purdue Extension Forester, shares how to identify trees native to Indiana.

Leaf Arrangement
Leaf arrangement is one of the first characteristics to check for on deciduous (trees that lose their leaves annually) broadleaved trees that make up the majority of our native species. The two arrangements we commonly find are alternate and opposite.

Opposite arrangement means the leaves are held on the twig directly opposite of one another. Alternate leaf arrangement means the leaves are arranged on the twig in an offset manner. We have one leaf, then another in a zig-zag or spiral fashion.

There are only a few native tree families with opposite leaf arrangements: Maple, Ash, Dogwood, Catalpa, Buckeye. You can remember these from the anacronym MAD Cat Buck – Maple, Ash, Dogwood, Catalpa, Buckeye. Almost all other native trees have alternate leaf arrangements.

Leaf Types
The next characteristic to check is if the tree has simple or compound leaves. To do this, we need to understand the difference between a leaf and a leaflet. A leaf has a bud at the base of the stem. The entire structure after the bud is the leaf.

A simple leaf is singular and never divided into smaller leaflets. A compound leaf consists of several or many leaflets joined to a single stem after the bud.

The full publication is available for download for $7 in the Purdue Extension Education Store. The field guide helps identify common Indiana woodlot trees.

Each week, the Intro to Trees of Indiana web series will offer a sneak peek at one species from the book, paired with an ID That Tree video from Purdue Extension forester Lenny Farlee to help visualize each species as it stands in the woods. Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available.

This week, we introduce the quaking aspen or populus tremuloides.

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.

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.

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.

According to the Hardwood Lumber and Veneer Series, 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.

This week, we introduce the large tooth aspen or populus grandidentata.

The large tooth aspen, also known as the big tooth aspen, needs full sunlight and thrives in areas where the soil has been disturbed and provides a good seed bed for its wind-blown seeds.

This species is identifiable by its triangular to round simple leaves with prominent, coarse, hooked teeth on the leaf margins. The long, flat leaf stems which flutter in the wind also are a good characteristic for identification along with its smooth olive green bark.

Large tooth aspen is found throughout the state of Indiana, while its close relative, the quaking aspen is found mostly in the northern portions of the state. This species is found from Nova Scotia west through southern Canada reaching to northeastern North Dakota. Its range also reaches southeast to the Ohio River and along the mountains to Tennessee and then to coastal New Jersey.

According to the Hardwood Lumber and Veneer Series, 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.

Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available.

First up, we introduce the white ash or fraxinus americana.

The white ash, which is typically found on higher and drier sites than its cohorts in the ash family, has been threatened due to the invasive beetle called the emerald ash borer. This species features opposite leaf arrangement, compound leaves with seven to nine leaflets, and squatty terminal buds as well as a bud that dips down into the leaf scar, which resembles a smiley face. The bark is gray, has a corky feel, and features an interlacing network of ridges forming a diamond shape.

Among the Hardwoods of the Central Midwest, white ash is the best known and preferred species among the five ash species located throughout the eastern United States. The species is found from the Great Plains east and from southern Canada south, with the exception of the lower Mississippi River Delta and coastal plains areas.

White ash is very hard and firm and with a 12% moisture content, it is comparable to white and red oak as one of the strongest woods. The wood grain appears much like oak, but does not have the large rays seen on the quartered surface of oak.

Ash is used on exposed surfaces in furniture and cabinets and also for millwork and flooring. Due to its high strength in bending and high shock resistance, it is also used in athletic equipment such as baseball bats and tennis rackets.

The history, color and texture and wood properties of white ash are available in more detail on the Hardwoods of the Central Midwest page for the species.

Purdue Forestry and Natural Resources’ extension efforts over the past two years amidst the COVID-19 pandemic were recognized in the Purdue Extension Specialist Quarterly newsletter.

The transition to virtual content brought expertise across subject matter areas, ranging from forestry and wildlife, to aquatic sciences and entomology, to the masses in the form of several video series which collectively earned nearly 150,000 views.

The FNR Extension team included: Jay Beugly, Jarred Brooke, Nick Burgmeier, Barny Dunning, Diana Evans, Lenny Farlee, Jason Hoverman, Liz Jackson, Brian MacGowan, Patrick McGovern, Wendy Mayer, Charlotte Owings, Lindsey Purcell, Bee Redfield, Shelby Royal, Bob Rode, Kara Salazar, Mike Saunders, Amy Shambach, Rod Williams, Mitch Zischke, as well as frequent Entomology contributors: Elizabeth Barnes, Cliff Sadof.

The feature in the fourth quarter newsletter begins:
“While Covid caused limitations on travel and in-person events nationwide, across Indiana, many were spending more time in outdoor recreational activities, hiking, bird-watching, hunting and fishing, or managing natural resources properties. Adjusting to the pandemic, the FNR team created an innovative and team-oriented instruction approach through skill-building in video production with coordinated connection and cross-promotion of resources.

“Forestry and Natural Resources (FNR) faculty, specialists, staff, and students, with invited partners across research and Extension, delivered 45-minute Ask an Expert Facebook Live programs for 35 weeks. Programs covered many FNR specialties: Animals & Insects (bats, bird, cicadas, coyotes, deer, fish, frogs, hellbenders, moles, pollinators, salamanders, snakes, toads, turtles, and wood pests); Plants & Ecosystems (invasive plant species, hardwood ecosystems, native grasses for wildlife, conservation tree planting, rainscaping, fall food plots, and selecting, planting and inspecting trees); and Management & Operations (prescribed fires, aquatic plant and pond management, and fish and wildlife management).
