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 red mulberry or Morus rubra.
Red mulberry has variable leaves, which can come without lobes (entire) or with two (mitten), three or even five lobes. Regardless of shape, the leaves have serrated margins and pointed tips and are arranged alternately on the twigs. The topside of the dark green leaves is sandpapery to the touch and has a matte or flat finish. The dark green leaves turn a golden yellow in the fall.
Basswood has leaves similar to the unlobed variety of red mulberry, but those leaves are smooth to the touch and have finely toothed margins. White mulberry, which is not native to Indiana, also has similar leaves to its cousin red mulberry, but those leaves are typically bright green and smooth, have more rounded teeth on the margins and feature a shinier upper leaf surface.
The bark of red mulberry is gray or brown in color with long flaky ridges, but may show some orange or tan peeking through the fissures in the bark.
The fruit of red mulberry, which hangs individually only the twig, resembles a small blackberry, with a dark purple or almost black color when ripe, that is favored by both birds and humans. Mulberry fruit is typically produced from mid-June to July.
Red mulberry, which is often found under the canopy of other hardwood trees in moist areas such as river bottoms as well as along wooded slopes, wood’s edges and shady roadways, are typically small understory trees, but can grow between 40 and 60 feet tall. Red mulberries are becoming less common on the landscape than the invasive white mulberry, but can be found growing throughout the eastern United States.
The Morton Arboretum warns that red mulberry is susceptible to a variety of pests, including leaf spots, witches brooms, canker diseases, powdery mildew, spider mites and scale insects.

This week, we introduce the red maple or Acer rubrum.
Red maple has simple three to five-lobed leaves with relatively shallow, v-shaped divisions between the lobes. The oppositely held leaves may resemble sugar maple but the V shaped shallow divisions stand in contrast to sugar maple’s deep u-shaped sinuses. In the early spring, it is one of the earliest native trees to flower, producing clusters of reddish flowers as well as reddish colored pairs of winged seeds/fruit. In the fall, foliage typically turns a bright red to maroon color.
The bark is gray and smooth in young trees and may become flaky in older trees.
Red maple, which is a popular ornamental and street tree selection, is one of Indiana’s soft maples alongside silver maple. It also can be found in Indiana woodlands in both moist and dry sites and in bottomlands and uplands.
Red maple, grow 50 to 80 feet tall and are found growing throughout the eastern United States including the coastal regions.
The Morton Arboretum warns that red maple was display chlorosis symptoms of pale green leaves with dark green veins in high pH soil and drought conditions. The species also does not tolerate heavy pollution.

This week, we introduce the silver maple or Acer saccharinum.
Silver maple has simple, typically five-lobed leaves with deeply cut divisions, or sinuses, between the lobes, with narrow lobes at the base. The leaves, which are silvery on the underside, are held oppositely on long leaf stems coming off the twigs. The bark on young trees is smooth and light gray, and darker and scaly on older trees.
Silver maple, which is commonly found in swamps and overflow bottomlands, is one of Indiana’s soft maples alongside red maple. It flowers early and sheds its large winged seed in the spring, typically by late May.
Silver maples, which prefer moist or well-drained soil, grow 50 to 80 feet tall and are found growing from the Great Plains eastward, excluding the Gulf and Atlantic coastal region. Most silver maple lumber is produced in the Mississippi Delta and central states region.
The Morton Arboretum warns that without proper and frequent pruning, high winds and ice can cause limbs to break on silver maple trees due to its weak wood and branch structure. These species is also drought sensitive, so be careful to provide supplemental water during dry periods.

This week, we introduce the black maple or Acer nigrum.
Black maple is easily confused with its cousin, the sugar maple, but there are a few key identifying characteristics to tell them apart. Black maple commonly has stipules, or miniature leaves, at the base of the leaf stem. This species features mottled gray stems and black pointed buds oppositely arranged on the stems. The lobed leaves are darker green and tend to droop down at the edges as the summer goes on.
The bark is lighter gray and smooth in young trees and features flakes or plates in older trees.
The seed or fruit of black maple is a winged seed which occurs in pairs and turns from green to brown when mature, similar to sugar maple.
Black maples, frequently found on moist or bottomland sites, grow 60 to 75 feet tall and can be 40 to 50 feet wide, providing excellent shade with their full foliage.
The Morton Arboretum warns again pruning maps in the spring as they are ‘bleeders’ and will lose large amounts of sap. This species also is susceptible to leaf scorch, verticillium wilt, tar spot and anthracnose and can be affected by borers and cottony maple scale. Black maple suffers from salt, drought and air pollution.
“Don’t be confused by the similarities. Use the tiny stipule (leaf) at the base of the stem, the drooping edges of the dark leaf and its dark buds on gray mottled stems to tell this native apart from its cousin sugar maple. Can you ID this native tree? Meet black maple or Acer nigrum.”

This week, we introduce the sugar maple or Acer saccharum.
This tree, also called hard maple, has simple leaves typically with five lobes, two smaller lobes at the base and three larger lobes at the top, with u-shaped sinuses between the lobes. The shade-tolerant species has opposite leaf arrangement with relatively long leaf stems as well as opposite branch arrangement. The thin twigs are green in their youth, turning to a medium brown as they age. The leaves produce brilliant fall colors ranging from yellow to burnt orange.
The bark of sugar maple typically has a light to medium gray color, but its appearance is variable and somewhat confusing. It can range from relatively smooth on saplings to minor crevices and ridging on medium sized trees to deeper ridges on older trees.
The seed or fruit of sugar maple is a winged seed which occurs in pairs and turned from green to brown when mature.
Sugar maples grow 60 to 75 feet tall and can be 40 to 50 feet wide, providing excellent shade with their full foliage.
Sugar maples produce maple sap, which can be used to make maple syrup. The yield of sugar maples is one of the highest among maple trees. The Morton Arboretum warns again pruning maps in the spring as they are ‘bleeders’ and will lose large amounts of sap. This species also is susceptible to leaf scorch, verticillium wilt, tar spot and anthracnose and can be affected by borers and cottony maple scale.

MyDNR Email Newsletter, Indiana Department of Natural Resources (IN DNR): Chronic wasting disease (CWD) is a fatal neurological disease affecting white-tailed deer, mule deer, elk, and moose. Hunters who want to have their deer tested for chronic wasting disease (CWD) can bring their deer to select Fish & Wildlife areas and State Fish Hatcheries during the hunting season.
Deer heads can be dropped into designated coolers or hunters can make an appointment for their deer to be sampled by a biologist during office hours. The 2022-23 sampling locations and their hours of operation are listed on the Fish & Wildlife: CWD website.
Hunters who submit a deer for CWD testing will receive a metal tag reminiscent of Indiana’s historical deer harvest confirmation process.
Alternatively, hunters may submit their deer to the Purdue Animal Disease Diagnostic Lab (ADDL) for testing for a fee. Hunters should complete the submission form and follow the shipping instructions on Purdue ADDL’s website.

Purdue College of Agriculture News: Purdue University has received $12 million of a $35 million project led by the American Forest Foundation and funded by the U.S. Department of Agriculture’s Partnership for Climate Smart Commodities to help family forest owners practice climate-smart forestry in Indiana and eight other states throughout the eastern half of the U.S.
The project’s other partners are The Nature Conservancy, the Center for Heirs Property Preservation, and Women Owning Woodlands. The project could sequester an estimated 4.9 million tons of atmospheric carbon—a greenhouse gas that affects climate—over a 20- to 30-year period.
“Our digital forestry group has been working on various tools and thinking about how to apply these tools to real-life problems,” said Songlin Fei, who directs Purdue’s Integrated Digital Forestry Initiative. “This is an opportunity to apply our expertise to solving part of the climate-change puzzle.” Purdue’s cross-disciplinary Integrated Digital Forestry Initiative includes faculty members from the colleges of Agriculture, Engineering, Sciences, Liberal Arts and Libraries and the Polytechnic Institute. The Integrated Digital Forestry Initiative, one of the five strategic investments in Purdue’s Next Moves, leverages digital technology and multidisciplinary expertise to measure, monitor and manage urban and rural forests to maximize social, economic and ecological benefits. “We’re bringing a traditional field into the digital age,” said Fei, professor, Forestry and Natural Resources, and Dean’s Chair of Remote Sensing.
Purdue will utilize advanced digital forestry technologies to do the measurement, monitoring, reporting and verification of carbon sequestrations that the project requires. The automated technology, applied at a regional scale with unprecedented accuracy, will be based on data collected by satellites and drones with various sensors, such as light detection and ranging (LiDAR). The team will also develop a simulation system that will utilize artificial intelligence to generate optimized forest management scenarios.
The work will result in a web-based tool that landowners can use to estimate and predict the climate-smart commodity market potential of their properties. The team is also building a smartphone-based app for tree measurement and monitoring.
American families own nearly 40 percent of the nation’s forests, yet few of them take part in forest carbon projects or work from a management plan. However, with proper management, trees can grow faster and sequester more carbon, Fei said.
Landowners will receive economic incentives for participating in the program. Payment to landowners will depend on which climate-smart carbon practices they use. Project staff or consulting foresters will also provide landowners technical advice and guidance in establishing a forest management plan.
