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 meet Eastern red cedar or Juniperus virginiana, one of the most common coniferous trees in Indiana.

This evergreen tree, also known as aromatic cedar, is unique in that it has both scale-like and sharp-pointed leaves. The foliage can be soft to the touch on mature trees or be quite sharp in seedlings and younger trees. The foliage turns from green to blueish green in spring to red or brown in winter.

The red cedar features a shreddy bark on both the trunk and branches, which is gray brown in color. It is slow growing but may live longer than 450 years.

The fruit of red cedar is a small cone, which resembles and is often referred to as a berry, that is blue in color and features a whitish bloom on the surface. The fruit is preferred by birds and wildlife of many varieties and is thus spread to roadsides, old pastures and other locations with plenty of sun and disturbed soil. It can be found in forest understories, but prefers direct sunlight.

This week, we meet the eastern white pine or Pinus strobus, which historically was one of the tallest trees in the eastern United States.

This conifer is the only five-needled pine native to Indiana, meaning that the bundles of needles coming off the branches in one location, also called fascicles, include five needles per bundle. These needles are typically between two and four inches long and are blue green in color. Needles remain on the tree for two to three years before dropping in the fall.

The bark on younger trees is dark and relatively smooth, and becomes quite furrowed in older trees. The eastern white pine adds a ring of side branches and a terminal shoot yearly with age.

The cones of this species are up to eight inches long, have relatively thin scales and are often covered with quite a bit of white sap or pitch. Cones remain on the tree for two years.

Eastern white pine trees typically grow to between 65 and 100 feet tall, but can exceed 150 feet tall in old growth forests. This species prefers acidic, moist and well-drained soil, but can tolerate alkaline soils. Eastern white pine is native to the central and eastern United States and Canada. Its range extends as far west as Arkansas, Missouri, Iowa and Minnesota in the U.S. and Manitoba in Canada. Its distribution reaches south through the Great Lakes states and in the Appalachian Mountains into northern Georgia as well as east along the Atlantic seaboard.

Much like the winter season, which has produced warm and relatively wet conditions across most of the state, the Climate Prediction Center is calling for continued above average temperatures and precipitation for Indiana this spring.

The March, April and May weather outlook is influenced again by the continuing La Nina conditions in the El Nino Southern Oscillation (ENSO). Unlike previous seasons, models are showing growing certainty that La Nina conditions will give way to ENSO-neutral conditions during the end of springtime. This would conclude La Nina’s current event lasting over two years.

The majority of the wetter than average predictions are likely to occur early in March and potentially through April. The end of La Nina would remove certainty of increased wet or dry conditions in May. Potential precipitation anomalies are predicted to be at least one inch greater than average precipitation across the state, with higher amounts in the south.

Temperature is also affected by the removal of La Nina, with the current warming signal weakening toward the end of spring. During early springtime, the glut of the warmth over the southeastern U.S. will spread northward into Indiana. Temperatures are too close to call for warmth or coolness in northwest Indiana, a line north of Terre Haute to South Bend. Predicted temperature anomalies are very low across the state, with a warming anomaly of 0.2 degrees Fahrenheit in the southern part of the state and 0.05 degrees Fahrenheit in the north.

Any areas of the state currently in abnormally dry conditions in the U.S. Drought Monitor are likely to be removed in the near future as these predictions play out. The Climate Prediction Center does not expect drought development anywhere in Indiana over the next three months.

For those with intentions of planting outdoors, lack of drought is good. However, planting windows may be shorter in the early spring period.

This week, we meet Butternut or Juglans cinerea.

Also known as white walnut, this species has slowly disappeared from the landscape due to a fungal disease. Butternut canker can cause large dead spots on the tree and can even girdle the tree and kill it before it can produce fruit.

Butternut has alternately held compound leaves that can be between one and two feet long, resembling a black walnut leaf with pairs of leaflets, but butternut often has a terminal leaflet. The toothed leaflets are green in the summer and yellow in the fall.

The bark is light gray and relatively smooth, but it may become furrowed with age, silver on top and darker between the fissures. Butternut twigs are light tan in color and have an elongated terminal bud. The leaf scar resembles the face of a monkey and it has a “hairy eyebrow” above the leaf scar/below the bud.

The fruit is a lemon-shaped edible nut approximately two inches in diameter with sharp ridges on the nut inside the husk. When they are green, the husk is sticky and clammy to the touch, unlike the smooth, thick skin of its cousin black walnut.

Butternuts, which grow 40 to 60 feet tall, prefer moist, well-drained, loamy soils, found in ravines and coves, but it can also grow on drier, rocky soil, especially that of limestone origin. It is usually scattered in the forest and associated with other species that prefer upland sites.

The Fall/Winter 2022 HEE Update newsletter is now available online. Research highlights and student news include:

• Bat Research in the News
• Thank You Danielle
• We Are Hiring
• A Second HEE Departure
• Welcome New Graduate Students
• HEE Publications

“The HEE Update” is distributed to anyone interested in receiving updates on the Hardwood Ecosystem Experiment (HEE). The newsletter includes updates of field work, media attention, committee meetings, extension events, job announcements, publications, and presentations. Anyone can receive this newsletter. If you would like to be added to the newsletter list email Dr. Mike Saunders, associate professor of silviculture, Purdue Forestry and Natural Resources, at msaunder@purdue.edu.

What is HEE?
The focus of forest science is increasingly shifting to the management of forests as complex systems rather than as simple agricultural landscapes—with a much greater appreciation for the interactive ecosystem processes. In addition, now for many forest landowners, the ecological value of their land is at least as important as the economic return. It is, therefore, vital to understand how forest management affects not only timber production, but also the overall function of forested ecosystems.

The Hardwood Ecosystem Experiment (HEE) is a long-term, large-scale experimental study of forest management and its impacts. The project was initiated in 2006 with partners including: Ball State University, Drake University, Indiana State University, Purdue Entomology, Indiana Department of Natural Resources (IN DNR), and the Indiana Chapter of the Ruffed Grouse Society.

For information about study sites, harvesting treatments, sampling design, and more, see our Study Design page and US Forest Service General Technical Report NRS-P-108, The Hardwood Ecosystem Experiment: A Framework For Studying Responses to Forest Management.

This week, we meet Black willow or Salix nigra. The black willow is one of several species of willow in Indiana, but it is the only tree-sized willow in the state.

This species has long, narrow leaves with short leaf stems, which are held alternately on slender, flexible twigs. Willows have a single scale covering the bud, which helps differentiate them from other species. The finely toothed leaves are medium green in the spring, changing to yellow-green in the fall.

The bark on young trees is smooth, but may be warty or feature some flaking. In old trees, the bark features prominent, light gray vertical flakes.

Black willows, which grow 50 to 70 feet tall, prefer moist or wet soils and often are found growing along streams or in other wetland areas. This species can tolerate alkaline soil, clay soil, occasional flooding and road salt.

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 meet Black walnut or Juglans nigra.

Also known as American black walnut or eastern black walnut, this species has compound leaves with several pairs of leaflets along the individual leaf stems. The leaves, which are arranged alternately on the twigs, can be between one to two feet long. They are green in summer and turn yellow in the fall. The terminal and lateral buds are fuzzy and tan and can resemble suede.

The bark has long, strong running ridges and in older trees can resemble alligator hide. Under the surface of the bark is a dark, chocolate brown color.

Black walnut trees produce nuts, which are ridged and rounded with very heavy shells. Nuts are encased in a thick yellow-green husk, which can leave a dark brown stain on skin. The nut shells require a heavy hammer hit or sharp animal teeth or claws to break open. The nut meat has a very strong aromatic flavor.

Black walnuts, which grow 50 to 75 feet tall, prefer to grow in sunshine and in high quality soils that are deep and well-drained. This species is often found as one of the tallest in the woodlands where they grow. The best quality trees are frequently found on flood free ledges just above stream banks. This species will live on poorer soils, but growth is slow and the wood quality is generally poor.

The natural range of the black walnut is the from the east coast west through the Great Plains. It ranges from Texas and Georgia north to central Minnesota, Wisconsin, Michigan and southern Ontario.
