Purdue Forestry and Natural Resources News & Stories: Vultures have a role to play as nature’s garbagemen, cleaning up animal carcasses, but what happens when a species goes from scavenging to harassing and even preying on livestock?

Pat Zollner, professor of wildlife science, along with PhD student Marian Wahl and their partners with the USDA Wildlife Services program are investigating black vultures in Indiana in order to better understand vulture ecology as well as to develop methods to mitigate future harm to Indiana livestock.

“Black vultures are relatively new to Indiana, they have been gradually moving in from the south, and right now there are a lot of unknowns that we need to figure out in order to make sound management decisions,” Wahl said. “Some of the pressing questions that we have are how many black vultures do we have here in Indiana, where are the birds located, how and where is conflict occurring, and how effective are different approaches to managing black vulture problems.

The aim of the research is two-fold. First, they are looking to see what causes some black vultures to become aggressive predators of livestock, instead of simply scavengers. Second, they are looking to learn signs that can determine whether an animal has been killed by vultures or simply scavenged, an important piece of evidence for livestock producers filing claims to the U.S. Department of Agriculture’s indemnity program hoping to recover compensation for their losses.

In order to achieve its goals, the research team is requesting the assistance of livestock producers through an online survey and also with the donation of calves believed to have been killed by black vultures. The qualtrics online survey is available now and will take only 15-20 minutes to complete. The survey is anonymous and data collected with be presented only in summary form and not via individual responses.

Purdue Landscape Report: J. Sterling Morton had a strong enthusiasm for trees and advocated intensely for individuals and civic groups to plant them. Once he became secretary of the Nebraska Territory, he further spread his message of the value of trees and Morton first proposed a tree planting holiday to be called “Arbor Day” at a meeting of the State Board of Agriculture.

The celebration date was set for April 10, 1872. Prizes were offered to counties and individuals for the largest number of properly planted trees on that day. It was estimated that more than 1 million trees were planted in Nebraska on the first Arbor Day.

Many other states also passed legislation to observe Arbor Day each year. By 1920, more than 45 states and territories were celebrating Arbor Day. The tree planting tradition became prominent in schools across the nation in 1882, with students were learning about the importance of trees as well as receiving a tree to plant in their own yard. They continue to do so today in many states.

Purdue Landscape Report: The hard freeze April 20th & 21st had many homeowners concerned about their perennial and annual plants in their landscape.  For the vast majority of perennial plants, there aren’t many issues long-term of concern.  Some foliage and flowers have significant damage, but the plants will recover, and possibly release new vegetative buds in severe cases.  The plants that suffered the most damage, and in some cases death, are the annuals planted by impatient landscapers and gardeners.  Planting annuals prior to the frost-free date (May 10^th in central Indiana) will more than likely cause a replant to occur.

In addition to the potential stress from the temperatures, many trees received broken limbs due the combined weight of the leaves/flowers and snow load.

If you maintain a client’s fruit trees (i.e. apples), there may be a significant impact on fruit production.  The Purdue Meigs Horticultural Research Farm, located about eight miles south of the West Lafayette campus, recorded a low temperature of 22^o F on April 21^st.  Dr. Peter Hirst, pomologist, indicated that at the current stage of flowering a temperature of 25^o F might result in a 90% bud kill.  Since there was a significant snowfall, the hope is that there was some moderation in temperatures.

Many landowners are interested in enhancing their property for wildlife. An important first step in that process is creating a plan. As the adage goes, “failing to plan, is planning to fail.” Just as you would have a blueprint if you were building a house or a map if you were starting a road trip, the same is true when you are managing habitat for wildlife on your land.

Landowners can tailor a wildlife habitat management plan to their own personal goals for their property. Maybe a hunter wants to increase the population of upland birds on their property, or a bird-watcher would like to improve the overall diversity of songbirds in their woodlands. Management plans help turn these goals into reality.

This 12 page publication titled Creating a Wildlife Habitat Management Plan for Landowners is packed with photos, resources and suggestions to help meet your goals.

Question: I am actually a Master Gardner in Hamilton County and I need help with a tree bark damage question. We have a beautiful dogwood tree that is about 18’ tall and 6” in diameter. By accident my husband backed into the tree with his truck while unloading mulch – he did not see it! Now there is severe damage to the bark at the bumper height – about 3” wide and 14” long. All the way down the bark is gone.

What are the chances the tree will survive? What if anything should I do at this point?

My husband wanted to cover it with painter’s tape to protect it but I know that is not good for the tree. Please let me know your suggestions as I do hope to save the tree if possible.

Answer: Well, that is certainly an unfortunate accident for the tree! There may be a rescue treatment worth trying that research has shown promise in sealing the wound. The ability for the tree to seal and close off wounds is based on species, age and energy resources. Additionally, follow these instructions…

1. Keep the tree healthy; mulch and supplemental watering during drought conditions.
2. Trace the wound with a wood file and sharp knife, removing any loose bark to a clean wound.
3. Take black plastic and attach it to the tree wound, just past the wound edge, using small, ¼” staples from a staple gun.
4. Attach the plastic so that it forms a seal which will help to maintain a moist environment for parenchyma cells to do their work at compartmentalizing and creating wound wood on the perimeter of the damaged area.
5. The plastic may need to be checked periodically to be sure it is attached well until removal.
6. Leave the wound covered for about 12 months, then remove carefully.

This will not guarantee recovery, but research has indicated it does facilitate healing more quickly in many species. Continue to monitor for health and recovery.

Good luck!

Purdue Landscape Report: PART 1 – The Importance of “Physical” Soil Testing
In my 40 years of teaching and consulting, one of the biggest and most frustrating problems I continually encounter is when so called “landscape professionals” and homeowners continue to apply annual soil fertilizers, lime, and other soil amendments without ever conducting a professional soils test.

Before planting long-lived trees, shrubs, flowering perennials and lawns, it is absolutely essential to have your soil tested for its physical, chemical, and biological properties. To have a beautiful landscape, an awesome lawn, or a very productive vegetable garden, we need to do soil tests because the health and vigor of everything we grow is directly dependent on the soil we are growing our plant’s roots in.

As an analogy, when you go to a family doctor or physician, why will they usually require a professional blood test from you?  They want to “show you the numbers” of your cholesterol, HDL, LDL, triglycerides, sodium, potassium, and a whole array of other very important blood tests. Again, if they prescribe you to take medications, but they are not helping and can actually hinder your health, lawsuits can definitely occur. I tell my students, before anything is applied on a client’s property, “show me the numbers”!

Although many intelligent homeowners and landscapers may have initially done a chemical soil test, many have never done a soil texture, soil compaction, and/or soil drainage test on their property or their clients. Why do we need to do these “physical” soil tests?  Think about it. For root growth, its not just about nutrient deficiencies, toxicities, or soil acidity problems, its about life giving oxygen in the root zone. Without oxygen, the entire ecosystem below ground will suffer. This is why I recommend you to determine your soil texture, (sand, silt, and clay %’s). Professional soils labs can determine your soil’s texture and that is very important, not only for knowing how much and when to water, but to determine what kind of fertilizers will work best for your soil. Many sandy soils are nutrient deficient because they have little negatively charged organic matter or clay to hold onto the positively charged nutrient fertilizers (cations). Excess rain and watering will leach many of the quick-release fertilizers, especially nitrate and potassium out of the root zone. This is why I recommend slow-release fertilizers on most soils so your plant’s roots will have available nutrients for a much longer time.

In this episode of ID That Tree, Purdue Extension forester Lenny Farlee continues to talk about the oak groups, this time focusing on the black oak species. Deep sinuses on the leaves and shinier coat, a dark blocky bark and acorns with loose shingle-like plates on the cap are some key identifiers to separate it from the red oak and others.

The goal of extension work is to provide practical solutions to local – and global – issues from agricultural production, environmental issues, natural resource conservation, land use and more.

Purdue Extension wildlife specialist Jarred Brooke’s work with prescribed fire is doing just that, as it is now being used to educate a new audience about various techniques of the habitat management method, the Wounaan indigenous community of Panama among others, thanks to the United States Forest Service.

Naomi Mills, a smokejumper squad leader for the Missoula Smokejumpers and fire specialist for USFS International Programs in the Latin America region, is utilizing Brooke’s Wildlife Habitat Hint series on prescribed fire techniques to illustrate various ignition techniques and methods as part of her virtual fire management training sessions.
