American Eagle Foundation: Our native vultures play a crucial role in reducing the spread of disease. However, as black vulture population increases, so too have reports of human-wildlife interactions. Researchers at Purdue University are currently performing research to better understand reports of black vulture depredation on livestock, and their ultimate goal is to find solutions that protect both livestock and birds.

AEF interviewed Dr. Pat Zollner, Dr. Zhao Ma, doctoral student Marian Wahl, and Ph.D. alumna Brooke McWherter for insight into their important research.

Check out the great information in this video discussing how this research was started and the concerns shared to the USDA office from state offices and the public.

Find out what types of vulture species are here in the United States and their roles in the story Protect Our Native Vultures, American Eagle Foundation.

Vultures have a role to play as nature’s garbagemen, cleaning up animal carcasses. If you have any questions regarding this research, or have any experiences to share, contact Marian Wahl.

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 White hickory or Carya tomentosa.

This tree, also known as mockernut hickory, has stout twigs like those of shagbark hickory and large terminal buds, but its bark is not shaggy. Instead, mockernut hickory features thick, interlacing bark ridges that is often silvery on top. Its leaves are made up of seven to nine leaflets that are hairy beneath, instead of five. The bud is very rounded, resembling a scoop of ice cream. The bud, leaf stems and twigs may have hair on them. The nuts of the mockernut hickory are smooth and round with mild ridges with four seams, which break open in the fall. The leaves produce a golden-yellow color in the fall.

Mockernut hickories grow to a mature height of 50-60 feet tall. They grow mostly in high dry ridges and other well-drained soil locations from New Hampshire west to Iowa and south to Texas and east to northern Florida except for the flood plain of the Mississippi Rive from Memphis south.

Purdue Landscape Report, Using Pneumatic Digging Equipment to Correct Root Deformations, Deep Planting, and Compaction on Established Trees: When transplanting trees, it is important to consider the long-term viability. Since the typical life span of an urban tree is 7-20 years (USDA), proper establishment techniques are very important to decrease this mortality rate. When a tree becomes established, it is much more difficult to correct below ground problems.

Root deformations can occur for many reasons in established trees, but the most common are due to not making corrections prior to transplanting. Plants that have girdling and circling roots must be addressed at the time of planting. If this issue is not addressed many problems may ensue when the tree is established, which includes decline, tree failure, blow-overs, and more.

Another common problem that occurs at transplanting is deep planting.  In the past, plants were often planted deep in the nursery for two main reasons: 1) cold protection of the roots and root flare and 2) prevent the use of staking. In fields that are cultivated, the soil often mounds around the trees which can increase the depth of the root flare. Additionally, when planting into the landscape, trees can be planted too deep, exacerbating the problems associated with planting too deep.

Deep planting can cause an increase in disease, insects, decreased tolerance to flooded soils, adventitious roots, and root circling/girdling. Day and Harris (2008) found that there is significantly more girdled root at 30 cm below grade than at grade or 15 cm below grade. They also found that excavated trees at 30 cm had more girdling roots than non-excavated roots at 30 cm.

Compaction can become an issue when trees are located in high traffic areas. Compaction will cause a decline in trees over time and become more susceptible to increased insect and disease pressure.

Excavating the root system with a pneumatic digger is a method that can be used to correct all of these problems. Removing soil around the tree will allow root deformations to be located and corrected. Removing the soil around the collar to correct planting depth and girdling roots will increase the longevity of the tree. Compaction can be reduced by using a pneumatic digger to remove the soil from the root hairs that are typically located in the top 6 inches of soil for most trees (Morris, et.al., 2009).

This week, we introduce the Shagbark hickory or Carya ovata.

This species is easily identifiable by its rough, shaggy bark, which is often peeling off from the trunk in thin strips. Its unique leaves feature five leaflets, two held opposite one another toward the base of the stem and three held at the end of the leaf. The fruit is a large, four-ribbed nut with a husk that will split all the way open. In the fall, shagbark hickory can provide fall color in the form of its stunning golden or yellow leaves.

Shagbark hickory has several close relatives. Shagbark can be differentiated from its cousin shellbark hickory, which features large stout twigs, seven to nine leaflets and typically has substantially larger nuts.

Shagbark hickories grow to a mature height of 60 to 80 feet tall. They grow mostly in moist, well-drained soil and are often found in upland woodlands and savannas, ranging across the Eastern United States, except in the gulf and Atlantic coastal plains, as well as in portions of Canada along Lake Erie and Ontario and the St. Lawrence River.

Shagbark hickory has a unique application in the furniture industry known as “Old Hickory Furniture,” which originated around 1900 in Indiana. This rustic furniture is made from hickory rounds or sapling with the bark left on, and was used in parks and other natural areas during his prime production.

The precipitous decline in songbird numbers over the past few decades has made national news and generated calls for action to address the issues contributing to this decline. One of the contributing factors to the decline of several North American bird species is the diminishing area of suitable habitat.

The initial assumption that many people have is this loss of habitat is forests or grasslands being converted into cropland or developments. While this does happen and is a concern in some areas, Indiana has actually been increasing our area of forest over the last several decades. An increasingly common habitat threat to several bird species is changing grassland or forest structure that occur through time in the absence of historic disturbances like fires or land management activities like thinning and harvesting.

The invasion of forests, wetlands, and grasslands by invasive plant species can also degrade or destroy habitat values for birds and other wildlife. Managing areas to reduce invasive species and introducing disturbances like prescribed fires, critical area plantings, thinning, and regeneration activities can improve habitat quality for a variety of declining birds.

The The Nature Conservancy in Indiana, partnering with birders, ornithologists, foresters, and wildlife biologists, has developed the Forestry for the Birds program, modeled from a similar program in Vermont.  The goal is to provide strategies that can benefit both forest management and bird communities, facilitating and simplifying the management of bird-friendly forests. “The Birders Dozen” were selected among declining birds that Indiana residents could identify by sight or song and need conservation action through habitat management.

Learn more about Forestry for the Birds, the Birders Dozen, and what you can do to help declining birds and other wildlife in Indiana. Find the Forestry for the Birds Pocket Guide which is a free download.

This week, we introduce the bitternut hickory or Carya cordiformis.

This cousin of the pecan, has anywhere from five to 11 leaflets, commonly seven to nine, on each alternately held compound leaf. Leaflets are much longer than they are wide and are often curved backwards.

A sulphur-colored, elongated bud is a standout identifying characteristic. Bitternut hickory has tight light to silvery gray bark with interlacing ridges throughout the life of the tree.

The fruit is a light colored, small, round nut, with a thick hull and a slight wing where the sutures meet. It is quite bitter and not preferred by animals or humans.

The bitternut hickory is one of the fastest growing hickory species in the state behind the pecan, and produces some fall beauty with yellow and gold foliage. Bitternut hickory, one of the most abundant and wide spread hickory species, can be found on dry gravelly uplands as well as rich moist bottomland from the Atlantic coast to the Great Plains, north through Minnesota and the St. Lawrence River valley, except the gulf coastal plains and the lower Mississippi flood plain regions.

This week, we introduce the hackberry or Celtis occidentalis.

This species is easily identified by its single-tooth margined leaves, which are lopsided with one side slightly higher than the other at the base of the twig. The gray, ashy bark is often warty/bumpy with smooth spots in between, although it may be fairly smooth like beech with warts and ridges spaced throughout. Many hackberries have clumps of distorted twigs in their tops call witch’s brooms. The fruit of the hackberry are small hard black berries, which are favored by birds.

The leaves of hackberry may be confused with elm at first glance, due to their sandpapery texture, but elms have doubly toothed margins with smaller teeth on top of the large teeth, unlike the single tooth appearance of hackberry. The leaves are often deteriorating late in the growing season after being attacked by a variety of insects.

Hackberry is often found along fence rows and field edges, but also may be found in the interior woodlands. This species prefers moist, well-drained soils, but will row on limestone outcrops and other droughty areas. It is native to the Midwest and upper eastern United States, ranging from the Great Plains to the east coast and from the Great Lakes states to central Tennessee and Arkansas.

Wild Bulletin, Indiana Department of Natural Resources Fish & Wildlife email newsletter, Fishing Tips, and Videos: Fishing can be hard for someone just starting—the choice in rods, reels, bait, lures, and lines can be mind-boggling. So, when first learning how to fish, keep it simple, light, and close to home.

A light fishing line with small bobbers, weights, hooks, and bait can help you get some excitement on the end of the line fast. Beginner anglers (kids or adults) may tire quickly and often give up while waiting for a giant bass to bite. Most beginners would rather pull in 25 minnow-sized bluegills than wait for one trophy catch.

If you are looking for additional information on how to get get started, you can learn more fishing tips about:

• Fishing equipment
• When and where to fish
