The Help the Hellbender Project is a joint project involving partners from across the country. The conservation outreach continues as the team shares how important it is that our household and farm management practices are aiming to help keep our rivers and streams clean.
The Help the Hellbender conservation efforts will continue expanding as 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. 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. To view article and the fourteen contributing partners in the article USDA Awards Farmers Helping Hellbenders Project $2.7 Million in Funding.

The Help the Hellbender team, led by Dr. Rod Williams, professor of wildlife science, has been honored by the Hoosier Outdoor Writers group with its 2022 Bayou Bill Conservation Award.
The annual conservation award is given in memory of the legendary Crothersville, Indiana, outdoor writer Bayou Bill Scifres, who was a founding member of HOW in 1969, and had his outdoors column published in The Indianapolis Star newspaper for 50 years.
“The Hoosier Outdoor Writers group was introduced to Dr. Rod Williams in 2019 when he came to our annual conference and talked to us about his work with hellbenders and the Help the Hellbenders program,” Tom Berg, Executive Director of HOW, explained. “Our members were very interested in learning more about hellbender conservation and restoration, and also about his involvement with captive breeding and propagation efforts across the state. It was interesting to us to hear that Purdue University, the Indiana Department of Natural Resources and other groups were working together on management plans to re-introduce and re-populate hellbenders throughout much of their historical range. This is exactly the type of conservation story that our members like to hear and relate to their audiences. It also aligns very well with our strong belief in the conservation of Indiana’s natural resources, so choosing Dr. Williams and the “Help the Hellbenders” program for this award was an easy task.”
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.
After five years of breeding efforts, Williams’ partners at the Mesker Park Zoo in Evansville, Indiana, successfully bred eastern hellbenders naturally in captivity in October 2020, signifying the culmination of a long and collaborative effort to breed the species and restore this endangered species to its native environment.
Williams’ hellbender lab is actively collaborating with the Indiana Department of Natural Resources, Indiana Division of Fish and Wildlife and The Nature Conservancy as well as several other partners across 13 states on a number of conservation projects and educational opportunities for teachers and children, farmers and more.

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 second of our oak varieties in Indiana, the Bur Oak or Quercus macrocarpa.
The bur oak has rounded lobes on the end of the leaves, which have deep sinuses and are very broad across the top. Leaves are typically dark green that turn yellow or brown in the fall.
The bark on bur oak is medium to dark gray in color with heavy ridges and plates, often so thick that it is often fire resistant and resistant to damage from burning. Bur oak may have terminal buds that include small hairs and resemble bear claws.
The fruit of the bur oak is an acorn with a large cap that features a hairy fringe forming a burr along the outside edge. The acorns vary in size, but average one inch in length, and the cap covers half to two thirds of the acorn.
Bur oaks, which grow to 70-80 feet tall and up to five feet wide, are common in both bottomlands and prairie regions, and can tolerate many different sites. Bur oaks can be found in nearly any county and any habitat type in Indiana. The natural range of bur oak is the eastern Great Plains from the Dakotas to Ohio to the eastern Appalachians, except through the southeastern United States. The range also extends into southern Canada.
Lumber from the white oak group, which includes bur oak, is among the heaviest next to hickory, weighing in at 45 pounds per cubic foot. It is very resistant to decay and is one of the best woods for steam bending. Bur oak, however, is somewhat weaker than other species in the white oak group.

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.”
