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 take a look at the eighth of our featured oak varieties in Indiana, the Pin Oak or Quercus palustris.

The leaves of pin oak are multi-lobed, with lobes coming out at nearly a 90-degree angle from the center of the leaves, and feature bristle tips like all members of the red/black oak family. On the pin oak, the alternately held leaves typically have less lobes than other members of the red/black oak group. In the fall, leaves change from medium green to a red to reddish brown color.

One key characteristic of pin oak are the branches, which angle downward especially on the lower part of the tree. The pin oak tends to keep its lower branches for a long period of time, which can create pin knots in the wood.

The trunk of pin oak is typically straight and single stemmed, while the bark is smooth and gray and may develop dark fissures with age.

The fruit is a rounded acorn with a relatively flat top with smooth scales, which covers only about one quarter of the nut.

Pin oaks, which grow to 60 to 70 feet tall and are relatively fast growing, are found mostly in moist to wet areas, such as streams, lakes and other wetlands, oftentimes in soils that have a medium to high acidity. Pin oaks also have been planted in many sites for landscape purposes.

The natural range of the pin oak is in bottomlands and imperfectly drained soils from New Jersey south to Virginia and west to Eastern Kansas and Oklahoma as well as south into North Carolina, Tennessee and Arkansas.

The Morton Arboretum states that pin oak suffers greatly from chlorosis or yellowing of the leaves in soils with high pH. As with other oaks, the pin oak should be pruned in the dormant season to avoid attracting beetles that may carry oak wilt, which can be a potential disease problem along with oak blister.

In 1978, Dan Cassens purchased a 10-acre plot of land close to the Purdue campus on which he planted a few Christmas trees as a side project. That plot of land developed into a family Christmas tree farm that Cassens and his wife Vicki have run for more than 40 years.

As the years passed, Dan, now a professor emeritus in the Department of Forestry and Natural Resources after retiring in 2017 following a more than 40-year career at Purdue, enlisted the help of students within the department for both seasonal work and longer-term work on the farm and within his small lumber business.

What started as a few extra hands around the tree farm has turned into a hands-on learning opportunity for more than 20 FNR students each year, teaching workers skills from cutting and handling trees to customer service.

“I don’t remember how it got started; I guess I needed somebody to help me and I probably knew a couple of students that were anxious to work,” Cassens said. “I don’t know how many years it has been going on now, but it keeps getting bigger. Last year at Christmas time we had 20 some students helping us part time with the trees. It’s a good group because they have hard, physical work to do, but then they’ve also got time to sit and talk too.”

The work begins in October to prepare the tree farm for its opening on the Saturday before Thanksgiving, a date determined by customer demand over the years. Cassens Tree Farm has both choose-and-cut and pre-cut trees in species ranging from Canaan fir, Fraser fir and Concolor (White) fir to Scotch pine and white pine and Norway spruce. Once cut, trees have to be shook to remove dead needles, have a fresh cut on the butt of the tree to ensure they stand straight on a tree stand, and many get baled or wrapped, which condenses a tree, making it easier to handle and preventing damage to limbs that may occur in transit.

Cassens does not have prerequisite skills for students who work on the farm, save a willingness to work hard, although there are plenty of jobs on the tree farm that require specialized skills.

“We can use anybody that wants to work hard and has time available,” Cassens said. “We try to find out what their abilities are, because we do need people that can drive trucks and use chainsaws. Chainsaw experience is absolutely critical in part of the operation, but other than that, anybody can work in the barn. It doesn’t require much skill, just hard work. It’s hard to get it all sorted out with 20 students with different hours that they can work and different abilities, but we try to find out their abilities and schedules and try to get them placed. Once we get it going, it’s good.”

Daniel Warner, a 2011 alumnus in wood products manufacturing technology, said Cassens was very understanding when it came to lack of knowledge and miscues.

“My first day helping with the tree farm, I didn’t even know why we were planting these little pine trees (I was thinking lumber not Christmas),” Warner recalled. “I was also recruited for the mortar removal on several tons of vintage bricks. On one hatchet wielding, mortar removing day, I managed to get my truck stuck in Dan’s yard in the mud. Needless to say, the fact that we are still good friends shows that there was a great deal of forgiveness.”

Many of the students who work at Cassens farm are juniors or seniors, but some come back two or three years in a row once a part of the workforce, and often bring friends along to join the crew.

2018 forestry alumnus Ed Oehlman helped at Cassens Trees for five years, beginning the spring of his freshman year.

“I met Dan my freshman year at Purdue and that spring he invited me out to the farm to help him plant Christmas trees and that started my adventure,” Oehlman said. “I got the pleasure of seeing the whole process, from helping him plant trees, spending many hours mowing, sheering trees, spraying and treating trees, and lasting helping sell trees. Selling Christmas Trees is to this day one of the best jobs I’ve ever had. You couldn’t work for better people than Dan and Vicki. The days could be long and active, especially Thanksgiving weekend, but they always made sure you were taken care with little snacks or pizza, sometimes even home made soup. It made the time go by so quick, you’d just get started and before you knew it we were shutting up shop. The best was the fun little gamble we did at the end of the day to guess how many trees we had sold that day, which always made work fun! Working with and for Dan was a great learning experience, and not just about wood/lumber or Christmas trees. I learned so many great life and business skills!”

Charlie Warner, 2021 forestry alumnus and current master’s degree student, worked at Cassens Farm for three and a half years as an undergraduate student and has helped out five seasons overall after being introduced to Cassens and the job his freshman year thanks to Damon McGuckin (sustainable biomaterials 2018) and Oehlman.

“Both Ed and Damon worked for Dan at the tree farm throughout their time at Purdue and told me about him and how he was as both a boss and a professor,” Warner said. “Unfortunately, Dan retired from teaching before I had a chance to take his classes but I made up for it when I started working for him. I started working on the tree farm helping Dan with various jobs, whether it was sawing lumber with his Wood-Mizer, loading and unloading his dry kilns where he dried lumber, cutting down trees and bucking the logs to get them ready for the sawmill and many other jobs and mechanical work around the farm. I learned so much from my few years working for Dan. In fact, he was one of the strongest voices urging me to continue my studies and work towards a master’s degree. Not only did Dan teach me everything there is to know about the wood products industry and more, but he also taught me how to communicate with industry employers. He gave me the skills to make myself extremely marketable to a few of my internship opportunities. Furthermore, he taught me many life lessons.”

Wild Bulletin, IN DNR Fish and Wildlife: In September, DNR biologists found two species of salamander, the long-tailed salamander, and the southern two-lined salamander, in Knox County, marking the first time since the 1800s that either has been documented along the lower Wabash River.

While both species are more widespread in other parts of southern Indiana, the small, rocky streams they inhabit are less common along the lower Wabash. Following this discovery, additional surveys conducted in parts of Knox, Posey, and Sullivan counties revealed more populations of southern two-lined salamanders; however, Knox County contains the only known location of a long-tailed salamander population in the region.

Salamanders and other amphibian surveys conducted by DNR biologists are supported by the Nongame Wildlife Fund. Contributions to this fund support a variety of rare and endangered wildlife.

Please visit Nongame and Endangered Wildlife to determine animals that are listed by the Indiana DNR as endangered or special concerns.

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 take a look at the sixth of our oak varieties in Indiana, the Northern Red Oak or Quercus rubra.

This native species is easily identified by its bark and its acorn. The bark looks like ski tracks or long running ridges that run up and down the sides of the tree, while the fruit is a large rounded acorn featuring a tight shallow cap with tight scales that resembles a beret sitting on top of a head.

Like other members of the red oak group, the leaves are multi-lobed and have bristle tips, including a sharp bristle tip on the terminal lobe. On the northern red oak, the alternately held leaves have veins that are palmate, or run out to the ends of the lobes from a single point in the middle. In the fall, the dark green leaves change to a bright red color.

The cluster of terminal buds at the end of northern red oak stems are smooth, shiny and reddish brown to brown in color. The twigs are somewhat angular in appearance.

Northern red oaks, which grow to 60 to 75 feet tall, are found mostly in upland areas. The natural range of northern red oak is the eastern United States and southern Canada, with the exception of the southern coastal plains. It grows well on moist, but well-drained soils.

The Morton Arboretum states that northern red oak has a high tolerance of salt and air pollution, making it a good tree for more exposed areas. This species prefers a well-drained, rich woodland site and it grows best in sandy, loam soil.

As with other oaks, the northern red oak should be pruned in the dormant season to avoid attracting beetles that may carry oak wilt. Galls and mites are common insect problems. This species can develop chlorosis symptoms in high pH soils.

This week, we take a look at the seventh of our featured oak varieties in Indiana, the Black Oak or Quercus velutina.

The leaves of black oak are multi-lobed, typically with seven lobes, with deep sinuses in between, and have bristle tips like all members of the red/black oak family. On the black oak, the alternately held leaves can be extremely variable in shape, but the tops of the leaves are dark and shiny and have a leathery appearance. Leaves change from dark green in summer to yellow or yellow-brown in fall.

One key characteristic of black oak are the terminal buds, which are angular and fuzzy, very large and light tan. Alternately, the cluster of terminal buds at the end of northern red oak stems are smooth, shiny and reddish brown to brown in color.

The bark is very dark in color with narrow, blocky ridges, and lacks the silvery running ridges that are found on northern red oak.

The fruit is a small rounded acorn with striping running up and down the sides and a fuzzy coating along the outside edge. The cap is deeper than northern red oak and the scales on the edge of the cap resemble loose, rough shingles.

Black oaks, which grow to 50 to 60 feet tall, are found mostly in dry, upland areas. The natural range of the black oak is nearly all of the eastern United States, from Nebraska, Iowa and Oklahoma to the west, dipping south into Texas, Louisiana, Mississippi, Alabama, Georgia and even a bit of the panhandle of Florida, extending along the eastern coastline, and northward into southern Ontario, Canada.

The Morton Arboretum states that black oak has a high tolerance of alkaline soils and dry sites, although it prefers acidic and dry soil. This species cannot withstand severe drought. It can also be difficult to transplant due to a deep taproot.

As with other oaks, the black oak should be pruned in the dormant season to avoid attracting beetles that may carry oak wilt, which can be a potential disease problem. Galls on leaves caused by mites or insects are common, but not harmful.

This week, we take a look at the fifth of our oak varieties in Indiana, the Chinkapin Oak or Quercus muehlenbergii.

Also known as the Chinquapin Oak, the leaves of this species feature shallow, evenly lobed margins, but appear to have sharp-pointed teeth at the end resembling red or black oaks. This sharp point, however, is due to a gland at the end of the leaves, and there is no bristle tip as are typically found on red and black oaks.  The shape of the leaves can be either broad like chestnut oak, or narrower.

Like other members of the white oak group, the bark of chinkapin oak is light gray and ashy, however it has a flaky appearance.

The fruit of the chinkapin oak is a small acorn that is dark brown or almost black in color. It has a cap that resembles a stocking cap, covering a third or half of the acorn, that features loose knobby scales. Under the cap, the acorn has a large white spot similar to that of a buckeye.

Chinkapin oaks, which grow to 50 to 80 feet tall, are found in both upland and bottomland areas. The natural range of chinkapin oak is the eastern United States, with the exception of the Atlantic coast and the immediate gulf coastal plains.

The Morton Arboretum states that chinkapin oak is best grown in rich, deep soils, but that it is often found in the wild on dry, limestone outcrops in low slopes and wooded hillsides. It notes that this species is one of the best oaks for alkaline soils. As with other oaks, this chinkapin oaks should be pruned in the dormant season to avoid attracting beetles that may carry oak wilt. This species also can be affected by anthracnose, oak wilt and two-lined chestnut borers.

With winter upon us this is actually a good time to look for owls on your property.  Most owls breed from January to March. You can either listen for calls in the evening, or use owl calls or recorded calls to get responses from owls in the area. We have three common species in Indiana and one rare species. All are non-migratory.  However, each has different needs and habits. The following descriptions were written by Barny Dunning, professor of wildlife ecology at Purdue. These accounts were originally published in the Indiana Woodland Steward (www.inwoodlands.org).

Owls are among the most intriguing animals native to Indiana. They have been celebrated in story from the myths of the early Greeks to the books of Harry Potter. Owls are common across much of the state, but are relatively unknown, probably because of the nocturnal habits of these birds. But since they are efficient predators of mice and rats, among other things, owls are very useful birds to have around. Three species of owls are common year-round residents in Hoosier forests. The largest of these is the great horned owl, one of the dominant predators of our forests. Most people are surprised to learn that the great horned owl is as common as the familiar redtailed hawk even though the owl is much less likely to be seen.

Great horned owls hunt in open areas but nest in large trees, where they take over a nest abandoned by a hawk, crow or heron. They are common where both woods and fields mix. The owls start breeding in January and February, adding new sticks to an old nest and laying a clutch of three eggs. Most species of owls nest very early in the year so that there will be a lot of easily caught prey in the form of young mammals and birds when the owl chicks are learning to hunt on their own. Many nests of the great horned owl are in snags or trees with broken tops, therefore retaining some of these forest features will provide good nesting spots for this dominant bird.

A second species of large owl is found in the larger woodlands of Indiana. The barred owl is most common in the interiors of forests and spends less time along the woodland edge. One major reason for this is the presence of the great horned owls, which will kill and eat a barred owl. Barred owls usually nest in the cavities of deciduous trees, laying their eggs in deep winter. Their dependence on tree cavities means that barred owls are likely to respond well to land management activities that retain large trees on a property and increase the number of snags with cavities. They also do well when there are forest patches of a variety of ages on a property, in addition to the older trees that provide nest sites.

Eastern screech-owls are the smallest resident owl in the state. They nest in small tree cavities and readily make use of nest boxes made especially for them. More than the other two species, screech-owls are found in suburban backyards, urban parks and on college campuses – anywhere there is a variety of trees and shrubs. Screech-owls feed on small prey such as insects, songbirds and mice. They breed later than do the big owls and have active nests in March and April. In addition to nest boxes, these owls will use old cavities excavated by northern flickers, tree holes created by storm damage, and hollow trunks of snags. Their ready use of a wide variety of cavity types makes our screech-owls a prime beneficiary of snag retention and other habitat improvement activities. Indiana’s smallest owl does not breed here, but its numbers during the fall migration can be in the thousands statewide. The northern saw-whet owl breeds from the most northern states on into Canada and migrates from there when food becomes scarce. “Swets” are an irruptive species, meaning their populations rise and fall dramatically from one year to the next on a roughly four-year cycle. A group of volunteer researchers in Yellowwood State Forest began studying the movements of these owls in 2002 as part of the larger Project Owlnet (www.projectowlnet.org). Their first year produced 71 owls on just one ridge in Yellowwood. Since then, the annual numbers have averaged around 70, but nearly 200 owls were captured and banded on that same ridge in 2007. The low point in the cycle was in 2009 when only nine owls were captured. There are now eight such banding stations scattered around Indiana. Brookeville Reservoir had the largest number of captures in 2009 with 32; while an Indianapolis station tallied only six. Some northern saw-whet owls winter in Indiana where forests with an open understory provide good foraging opportunities throughout the winter months.

The rarest owl in Indiana is, paradoxically, the species with the largest geographic range. Barn owls are found across the globe, but in the Midwestern United States their populations have declined dramatically. The species is considered endangered in Indiana. Barn owls originally nested in tree cavities, but when early settlers built barns and other farm buildings, the owls were quick to adapt. They are not limited to barns however, as recent Hoosier nests have been found in old churches, silos, and within the walls of abandoned buildings. To be suitable, human structures must have openings that allow the owls to fly in and out and an interior area that is undisturbed and big enough for the nest. The biggest factor in their decline has been changing agricultural practices. Barn owls hunt in open areas such as pastures, but do not use row crop fields. As Hoosier farmers converted pastures to corn and soybean, the barn owl lost its hunting grounds. Farmers in the southern part of the state that still retain some open grassy fields on their land can contact the state Department of Natural Resources to have a barn owl nest box added to their outbuildings if they don’t have appropriate nest sites.

The U.S. Department of Agriculture (USDA) announced it is awarding $197 million for 41 locally led conservation projects through the Regional Conservation Partnership Program (RCPP). RCPP is a partner-driven program that leverages partner resources to advance innovative projects that address climate change, enhance water quality, and address other critical challenges on agricultural land.

“Our partners are experts in their fields and understand the challenges in their own backyards,” Agriculture Secretary Tom Vilsack said. “Through RCPP we can tap into that knowledge, in partnership with producers and USDA, to come up with lasting solutions to the challenges that farmers, ranchers, and landowners face. We’re looking forward to seeing the results of public-private partnership at its best, made possible through these RCPP investments.”

The “Farmers Helping Hellbenders” project, led by Dr. Rod Williams and Purdue Extension wildlife specialist/Help the Hellbender project coordinator Nick Burgmeier, is among the projects set to receive funding through the RCCP Classic fund, which uses NRCS contracts and easements with producers, landowners and communities in collaboration with project partners.

Fourteen contributing partners will assist in the project:

• Mesker Park Zoo and Botanic Gardens
• Fort Wayne Children’s Zoo
• Indianapolis Zoo
• Indiana Department of Environmental Management
• Crawford County Soil and Water Conservation District
• Floyd County Soil and Water Conservation District
• Harrison County Soil and Water Conservation District
• Washington County Soil and Water Conservation District
• Crawford County Cattleman’s Association
• Harrison County Cattleman’s Association
• Washington County Cattleman’s Association
• Cryptobranchid Interest Group
• The Nature Conservancy
• Wallace Center at Winrock International

With help from nearly $2.7 million in RCCP funding, the project aims to improve hellbender habitat in a four-county region in south central Indiana, the only remaining habitat for hellbenders in the state, by expanding the use of agricultural conservation practices that lead to decreased sedimentation in local rivers systems.

Sedimentation is a major cause of hellbender decline and reduced sedimentation will increase available habitat for hellbenders, mussels, and aquatic macroinvertebrates. This project also will address soil and nutrient loss, which are concerns for agricultural producers, as the targeted conservation practices and systems have been shown to have long-term benefits for agricultural systems and operations.

“Through this initiative, focused on Crawford, Floyd, Harrison, and Washington counties, we expect to improve water quality and aquatic wildlife habitat,” Burgmeier said. “Simultaneously, we hope to improve soil retention and nutrient availability to crops by helping farmers implement practices such as cover crops, riparian buffers, grassed waterways, etc. Additional benefits will include increases in riparian and pollinator habitat and increased protection for karst habitat through the selected targeting of sinkholes.”

As part of each project, partners offer value-added contributions to amplify the impact of RCPP funding in an amount equal to or greater than the NRCS investment. Private landowners can apply to participate in an RCPP project in their region through awarded partners or at their local USDA service center.

“RCPP puts local partners in the driver’s seat to accomplish environmental goals that are most meaningful to their community.  Joining together public and private resources also harnesses innovation that neither sector could implement alone,” Indiana NRCS State Conservationist Jerry Raynor said. “We have seen record enrollment of privately owned lands in NRCS’ conservation programs and RCPP will be instrumental in building on those numbers and demonstrating that government and private entities can work together for greater impacts on Indiana’s communities.”

For much of the last 16 years, Williams and his team have been researching eastern hellbenders, spearheading regional conservation efforts and advancing hellbender captive propagation, or the rearing of this ancient animal in captivity and their eventual return to the wild.

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 take a look at the third of our oak varieties in Indiana, the Swamp White Oak or Quercus bicolor.

The swamp white oak has leaves with wavy, uneven lobed margins with blunt teeth, which are wider toward the tip than at the base. The alternately-held leaves are typically dark green on top with a silvery-white underside, which turn orange, gold and yellow in the fall.

The bark on swamp white oak is similar to that of white oak and often peels back especially on younger trees. Mature bark is dark gray-brown with flaky/shreddy bark or blocky ridges that are consistent up and down the tree.

The fruit of the swamp white oak is an acorn held on a long stalk, typically an inch or inch and a half long, called a peduncle.

Swamp white oaks, which grow to 50 to 60 feet tall, are named for the fact that they often grow in wet places, such as line drawing of swamp white oak acorns and peduncle. upland swamps and lowlands. This species also can tolerate well-drained upland sites, making it a good option for landscape plantings. The natural range of swamp white oak is the northern half of the eastern United States, reaching as far south as Missouri, southern Illinois and Kentucky, and north into Wisconsin, Michigan and Pennsylvania.

The Morton Arboretum warns to plant swamp white oak in full sun and shares that the species is one of the easiest oaks to transplant and is more tolerant of poor drainage than other oaks. It also notes that oaks should be pruned in the dormant season to avoid attracting beetles that may carry oak wilt. Swamp white oak can be affected by pests such as anthracnose, powdery mildew, chlorosis in high pH soils, insect galls and oak wilt.

In general, lumber from the white oak group is among the heaviest next to hickory, weighing in at 47 pounds per cubic foot. It is very resistant to decay and is one of the best woods for steam bending.

White oak lumber has been used for a variety of purposes including log cabins, ships, wagon wheels and furniture. It also is preferred for indoor decorative applications ranging from furniture, especially in churches, to cabinets, interior trim, millwork and hardwood flooring and veneers. It also may be used for barrel making.

Its density and durability make white oak a favorite for industrial applications such as railroad ties, mine timbers, sill plates, fence posts and boards, pallets, and blocking, as well as industrial, agricultural and truck flooring.
