Familiar with surprise lilies? Indiana has a native surprise onion!

Many yards where I grew up in southern Indiana were graced with surprise lilies. These plants grew long narrow leaves in the spring, which faded and died by early summer. After a pause with no evidence of the plant, long stems with pink lily-like flowers emerged, with no leaves to be seen.

While these plants are not a native species, we do have a native with similar habits that is a distant relative of the surprise lily. That plant is ramps, also known as wild leek and a variety of other local names. There are two species of ramps recognized now – the more common broad-leaved ramps, Allium tricoccum, and the narrow-leaved ramps, Allium burdickii. Ramps are related to onions and garlic and have odor and taste reminiscent of those plants. Ramps foliage emerges early in the spring and was one of the earliest green edibles available to First Nations people and early European settlers.

Many communities developed festivals or celebrations centered on the emergence of ramps as a sign of spring and some fresh greens to eat. The bright green leaves emerge before the tree leaves and fade before summer, but by the first half of June expect to see thin stems with a rounded cluster of small white flowers emerge – our surprise onion! It may take a ramps plant seven to ten years from seed to produce a flower, so this is a slow-growing and long-lived forest perennial. The flowers are pollinated by insects and produce round black seeds that may stay on the stalk through winter.

Look for ramps in well-shaded forest areas with moist soils. They have a scattered distribution across Indiana, so you won’t find them in every woodland. The leaves and bulbs are edible, but absolute certainty of ID is essential as there are some toxic plants that look similar.  Check ID references and spend some time with experienced foragers before eating any wild plants. The onion/garlic odor of ramps is a good indicator for positive ID.

Since this is a slow growing plant with a limited distribution, over-collection is a threat. A responsible harvesting technique is to harvest one leaf from mature plants, leaving the other leaves and the bulb. If you harvest the whole plant, take less than 5 percent of the plants in a patch, allowing seeding and bulb division to repopulate the area. Seed or bulbs can also be used to plant new patches. So keep you eyes open for our local surprise flowers this June – ramps!

The Farmers Helping Hellbenders program is accepting applications for the second round of its Indiana Natural Resources Conservation Service’s Regional Conservation Partnership Program (RCPP) project. The project aims to assist with the conservation/recovery of eastern hellbender salamanders and improvement of aquatic resources in south central Indiana.

Eligible farmers and landowners, who wish to obtain funding to implement practices designed to keep nutrients and soil resources on fields and improve their watersheds, should contact their local NRCS office before May 10 to apply. Financial assistance is available for agricultural lands within the Blue River-Sinking Watershed boundary in Crawford, Floyd, Harrison and Washington counties, where the eastern hellbender can be found and is being actively managed.

Eligible practices for farmers in the project area include conservation cover, grassed waterways, wildlife habitat planting, nutrient management, riparian buffers and many others. Interested farmers and forest landowners who wish to implement conservation practices on their land should discuss their options with their district conservationist. Contact your local district conservationist by visiting Farmers.gov/Service-locator.

While NRCS accepts program applications year-round, Indiana producers and landowners should apply by May 10 to be considered for the current RCPP-Hellbender funding cycle. Applications received after May 10 will automatically be considered during the next funding cycle.

“The Farmers Helping Hellbenders RCPP project enables us to leverage partnerships to make a lasting positive impact on the habitat of the eastern hellbender salamander,” said Damarys Mortenson, state conservationist for the USDA’s NRCS in Indiana. “This project allows Indiana farmers and forestland owners to conserve the vital natural resources on their land while also protecting the habitat for hellbenders and other aquatic animals. It is a win-win.”

The eastern hellbender (Cryptobranchus alleganiensis) is a large, fully aquatic salamander, nicknamed the snot otter, water dog, devil dog, Allegheny alligator and water eel among other things. Their decline statewide has been documented as far back as the early-to-mid 1900s as a result of habitat loss and poor water quality. Hellbenders, which are listed as an endangered species in Indiana, play an important role in aquatic ecosystems and are indicators of clean water. Eastern hellbenders need clean water to survive as they breathe through their skin by absorbing oxygen from the river and stream water in which they live.

Hellbender populations are declining across their range, from Missouri to New York. This decline, which affects the hellbender population in Indiana’s Blue River, is likely caused by human influences such as habitat degradation and destruction. The stream-bottom habitat of hellbenders can be degraded by sediment from eroded banks and fields and destroyed when streams are dammed or dredged. Hellbenders are also captured inadvertently by anglers or purposefully for illegal sale in the pet trade. Finally, emerging diseases may be impacting some populatio​ns of hellbenders. Specifically, the chytrid fungus (Batrachochytrium dendrobatidis) and Ranavirus (family Iridoviridae) are considered to be major threats to the persistence of hellbender populations across their range.

For much of the last 17 years, Dr. Rod 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 partnership had a major breakthrough over the summer of 2023 with the documentation of a young hellbender salamander in the Blue River while conducting routine surveys. This discovery is significant because over the past three to four decades, only adult hellbenders have been documented in the Blue River. The presence of a young salamander suggests that conservation efforts and rearing programs are accomplishing their goals for the recovery of this endangered species.

The Farmers Helping Hellbenders RCPP project is made possible by $2.7 million in funding from the U.S. Department of Agriculture’s RCPP, Purdue and other partnering organizations. The project is led by Purdue with assistance from 14 collaborating public and private organizations on the state and local level including NRCS. The goal of the project is to improve hellbender habitat in a four-county region in south central Indiana by expanding the use of agricultural conservation practices that lead to decreased sediment in local river systems. The project aims to improve water quality, enhance aquatic habitat, increase aquatic wildlife populations, increase riparian and pollinator habitat and protect karst topography.

Deer are an important part of Indiana woodlands and represent a true conservation success story. Many Hoosiers spent time in the woods pursuing deer during hunting season or marveling at them during walks in their woodlands. But as recently as the 1930s deer were absent from Indiana woodlands. Restocking efforts led by the Indiana Department of Natural Resources helped reestablish deer populations across the state. However, deer populations have rebounded beyond what the land can support in many areas, leading to issues like crop damage, deer-vehicle collisions, and damage to woodlands.

Deer overabundance can pose a threat to the future health of many Indiana woodlands. Deer are considered a “keystone” species, which means their feeding habits (browsing) can shape our woodlands’ look and their plant and wildlife communities. This publication will outline some of the impacts deer can have on Indiana woodlands and what signs and symptoms to look for in your woods.

Learn more about the amount of impact in this new publication:
Low Impact: When deer have little impact on your woodlands, you often see a high diversity of plants. An abundance of preferred species like trillium (picture) can also be a sign of low deer impact.

Moderate Impact: When sprouts of preferred species are “hedged” or kept short by deer browse and browse on less preferred species is noticeable, then deer impact may be moderate.

High Impact: If invasive species like Japanese stiltgrass and garlic mustard are common in your woodland, it may be a sign that deer are overbrowsing native plants.

High Impact: If invasive species like Japanese stiltgrass and garlic mustard are common in your woodland, it may be a sign that deer are overbrowsing native plants.

Very High Impact: Browse lines indicate a severe deer problem and appear when deer browse all plants within their reach (<6 feet).

Deer are an essential part of our ecosystems, but the phenomenon of too many deer should be of concern to forest landowners and the public in general. Deer are a “keystone” species, meaning their browsing can impact forest and wildlife communities. It is clear that when deer become overabundant, their impact on the environment can be problematic. But by understanding the impacts deer have on our woodlands, their food preferences, and how to assess and evaluate impacts in your woodlands, we can begin to address the problems caused by overabundant deer.

Wherever deer exist, they will be impacting the ecosystem through browsing. But at what level is that impact considered harmful? Many ecologists consider deer impact harmful when deer begin to reduce plant diversity in a woodland through browsing. knowing the exact number of deer on a property is difficult to measure and unnecessary. There are relatively easy ways to estimate the number of deer on a property or track trends in population sizes over time. This publication is written to help woodland owners better understand how to monitor deer and their impact.

Monitoring deer impact is done by surveying what deer eat in a forest and how intensively they browse those species. Deer are browsers rather than grazers (like bison and cattle), preferring to eat forbs (broadleaf herbaceous plants), vines, shrubs, and trees rather than grasses. Deer also select specific parts of the plants (e.g., leaves, twigs, and young tender growth).

Monitoring Deer Impact Methods:

• Browse Surveys
• Indicator Plants
• Assessing Vegetation Impacts from Deer
• Ten-Tallest Method
• Twig-Aging
• Oak Sentinel
• Stump Sprouts

Purdue Landscape Report: It’s that time of year when we remind everyone to watch for spotted lanternfly (SLF) infestations. Spotted lanternfly is an invasive insect first detected in Pennsylvania in 2014, and has since spread throughout the eastern USA. Its preferred host is the invasive Tree-of-Heaven, but it also feeds on a wide range of important plant species, including grapes, walnuts, maples, and willows.

There are two known populations of SLF in Indiana. The first population was found in 2021 in Switzerland County, and the second population was found in Huntington County in 2022. The Indiana Department of Natural Resources (IDNR), Division of Entomology and Plant Pathology, has launched a delimiting survey throughout the two counties to delimit its range and monitor for activity.

Egg hatch was confirmed in Huntington County and Switzerland County in mid-May at the two known sites. A few adults have been caught about one mile south of the core infestation site in Huntington; however, there are not any new infestations reported as of July 2023. IDNR employees have completed several egg scraping events at the infestation sites, removing over 16,800 egg masses so far this year. That’s over 672,000 eggs!

Finding this invasive insect early is crucial to preventing its spread as long as possible. Currently, SLF nymphs are in their 1^st-3^rd instar, so watch for small, black, white-spotted bugs on Tree-of-Heaven. Later instars are black and red with white spots. The adults are about 1 inch long, with very brightly colored wings. The forewings are light brown with black spots, and the underwings are a striking red and black, with white band in between the red and black. When at rest, the adult SLFs appear light pinkish-grey.

Purdue Landscape Report: I think white pines are beautiful trees, especially at maturity, and they have the added advantage that they are one of the few conifers that don’t try to kill you with their needles. Besides working with the foliage, have you ever had to “rescue” a child who climbed too high in a spike-infested deathtrap of an evergreen? Did you develop the rashes to prove it? Not with a white pine!

My kids haven’t had the chance to climb a mature white pine. Many seem to decline at about 15-20ft. We have been describing this issue as white pine decline, but it isn’t entirely easy to explain. There are a number of factors that influence overall plant health and that can contribute to plant decline, but let’s focus on white pines here. White pine decline is typically attributed to root stress that can be caused by or exacerbated by high soil pH (chemically unavailable nutrients), heavy soil texture (clays), compaction, and excessive soil moisture.

Anything that affects the roots can affect the overall health of the tree, so if the roots are compromised and they cannot uptake water or nutrients, the tree will decline due to lack of nutrients or even lack of water. Needles on an affected tree will turn yellow and eventually brown and fall off prematurely (Figure 1). A symptom of white pine decline includes stems that have shriveled or desiccated bark because roots are not functioning properly and cannot pull in enough water (Figure 2).

White-tailed deer are an important part of our Hoosier natural areas and a true conservation success story. Once extirpated from Indiana, deer now thrive in all 92 counties.

Deer can significantly impact the make-up of plants in our natural areas through the plants they eat (referred to as browsing). When the number of deer on the landscape is in balance with the available habitat and deer browsing is at a low intensity, deer can positively impact our forests’ plant diversity. When deer are overabundant, their browsing can impact forests in a variety of negative ways.

5 Steps to address deer impacts to Indiana Woodlands:
Understanding
Understand how deer impact Indiana’s forest ecosystems.

Identify
Identify signs and symptoms of deer impact in your woodland.

Monitor
Monitor how deer are impacting your woodland over time.

Manage
Decide how to manage deer and their impact on your woodland.

Evaluate
Evaluate if the management actions you took reduced deer impact on your woodland.

Check out the new Deer Impact Toolbox website for publications and more details to discover the steps landowners and land managers can take to understand, monitoring, and manage deer impacts to Indiana’s forests.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Researchers at Purdue University are studying the willingness of hunters and nonhunters to help reduce the spread of chronic wasting disease (CWD) in white-tailed deer. CWD is a fatal neurological disease affecting deer and is caused by an infective protein (prion) that damages the animal’s nervous system. CWD is contagious to deer and can spread through deer-to-deer contact or through contaminated environments. To date, CWD has not been detected in Indiana. No cases of CWD have been recorded in humans.

Researchers at Purdue University are seeking volunteers to participate in this research study. Information collected may help inform Indiana DNR’s response to CWD. Participants will answer online survey questions and use a web app that shows how CWD may spread. The activity and survey questions take about 30 minutes to complete. The study is open to everyone 18 years or older. All that is required to participate is a computer or tablet. Follow this link to Purdue’s website to participate in the study.

Chronic wasting disease (CWD) is a fatal neurological disease affecting white-tailed deer, mule deer, elk, and moose. It is a member of a group of diseases called transmissible spongiform encephalopathies (TSEs), or prion diseases. For more information about this disease visit Indiana Department of Natural Resources – Chronic Wasting Disease (CWD).

For questions about this study, please email the research team at  cwdwebapp@purdue.edu and place in the subject line: “Web App Use and Intention to Reduce Chronic Wasting Disease Spread; Principal Investigator – Dr. Patrick Zollner; IRB Number – IRB-2023-1039″.
