Illinois-Indiana Sea Grant Newsroom: May 2022, Illinois-Indiana Sea Grant (IISG) launched its third buoy in southern Lake Michigan—this one based in the busy waters off Navy Pier. This new buoy with its flow of in-the-moment data is helping the National Weather Service (NWS) Chicago develop more accurate forecasts and warnings, especially related to nearshore wave heights and wind speeds.

This third buoy, known affectionately as Chuoy, joins IISG buoys in the nearshore waters of Michigan City, Indiana and Wilmette, Illinois. Together, these three, along with two University of Illinois buoys closer to the Wisconsin border, paint a comprehensive picture of coastal lake conditions in the two states. In addition to meteorologists, the data is used by scientists, boaters, anglers and beach goers.

“Information from these buoys allows recreational water users to make better informed decisions when it comes to safety,” said Ben Szczygiel, IISG buoy specialist. “The data allows people to plan for current conditions and avoid the water when there are increased safety concerns.”

MyDNR, Indiana’s Outdoor Newsletter: The Indiana Natural Resources Foundation, in partnership with the Division of Forestry, is planning another busy year for the Indiana Tree Project. In 2022, more than 11,000 trees were added to Indiana’s public lands through Indiana Tree Project plantings, and this year is expected to be another successful year.

Through a partnership with the Division of Forestry, we are helping Indiana’s forests grow, one tree at a time, with the Indiana Tree Project. Healthy forests in Indiana promote wildlife habitats, clean air and an abundance of outdoor recreation opportunities. It is estimated that 85 percent of Indiana was once forested. Today, only 19 percent of the state is forested. The Indiana Tree Project is much more than just planting trees. Through this project we are adding new acreage to Indiana’s State Forests and we’re trying to add 1,000 acres of new forested land.

When you support the Indiana Tree Project, we provide you with an official tree certificate to demonstrate your support for the smart management of Hoosier forests. It includes the coordinates for the acre on which your tree is, or will be, planted.

Newsletter can be found online: MyDNR Email Newsletter

Purdue Landscape Report: Asian jumping worms, a group of invasive earthworms, have gained a significant amount of media attention in the last several weeks, and for good reason.  Unlike the nightcrawlers and other earthworms we know, Asian jumping worms do not improve soil health to the benefit of plants.  Instead, jumping worms (also called crazy worms, snake worms, or ‘Alabama jumpers’) almost completely strip nutrients out of soil, altering the soil structure and severely impairing the ability to develop many kinds of plants. After they are done with an area, Asian jumping worms leave behind soil that has a texture similar to that of coffee grounds and very low nutritional value. On top of this, Asian jumping worms are capable of reproducing asexually, allowing their population to grow very rapidly and making them an invasive species of some concern.

Identification
The good news is that Asian jumping worms are not well-suited to Indiana’s environment.  They aren’t capable of surviving winters in any life stage except as an egg, meaning their activity periods are limited to late June to the first hard frost of the year.  If you see worms outside of this period, it’s highly unlikely an Asian jumping worm.  There are also a few traits the worms have that you can use to visually confirm their identity.  First off, Asian jumping worms are accurately named; when handled, they writhe and thrash similar to snakes, setting them apart from common earthworms and nightcrawlers.  Jumping worms also tend to have drier skin that has an almost iridescent appearance, as compared to the slimy, moist texture of the beneficial earthworms we need for good soil health.  The most consistent feature is an organ known as the clitellum, or the reproductive organs of worms.  On common earthworms, this looks like a saddle-shape that partially covers several segments, is normally reddish-brown, and is raised off the surface of the body.  On an Asian jumping worm, however, the clitellum is indistinguishable from other segments, save for their pale, milky color.

This is the eighth in a series of consumer guides that describe fish and shellfish farmed in the Midwest region of the United States. The fact sheet also includes culinary characteristics, cooking tips and a recipe for Easy Baked Salmon.

Atlantic salmon, also known as sea-run salmon, kelts, and black salmon, are anadromous finfish in the Salmonidae family. Anadromous fish start their lives in freshwater and migrate to saltwater, returning to freshwater to spawn. Atlantic salmon are the only salmon species found in the Atlantic Ocean. They are native to the North Atlantic Ocean and coastal streams of North America and Europe and landlocked populations have been documented.1,2 They can be found in coastal waterways, freshwater streams, and lakes. They have long silver bodies with small black spots, appearing brownish from above. During spawning, males turn bronzish-purple with red spots and develop a hook-like lower jaw, known as a “kype.”

The Natural Resources University podcast group received the gold award in the podcast or radio category from the Association of Natural Resource Extension Professionals (ANREP). The NRU podcast group includes the Habitat University podcast co-hosted by Purdue Extension wildlife specialist Jarred Brooke and Adam Janke, an extension wildlife specialist at Iowa State University.

“Receiving the ANREP Gold Award is an honor,” Brooke said. “What started as casual conversations amongst colleagues about creating science-based natural resources podcasts has blossomed into a podcast network with multiple unique podcasts and over 100 episodes. This collaboration has been a great avenue to get up-to-date science about natural resource management into landowners and managers’ hands (and ears).”

The NRU podcast group initially began with four science-based podcasts covering different aspects of natural resource management: Deer University, Pond University, Fire University and Habitat University.

Deer University, which is hosted by Dr. Bronson Strickland and Steve Demarais, focuses on the science of deer, including deer ecology, biology and management.

Pond University, which was co-hosted by FNR’s Mitch Zischke and Megan Gunn before ending its 11-episode run in August 2021, covered topics from pond habitat to fish stocking, vegetation control and pond construction.

Fire University, which is hosted by Dr. Marcus Lashley, covers the gamut of the latest research in fire ecology and how it relates to management of wildlife and plant communities.

Habitat University, hosted by Brooke and Janke, discusses the science behind wildlife habitat management and how landowners and manages can use different habitat management practices to improve their land for wildlife.

New to the NRU family in 2022-2023 are:

• Wild Turkey Science – Dr. Marcus Lashley and Dr. Will Gulsby bring you the latest research on wild turkey ecology and management
• Timber University – Dr. Brady Self and Dr. Shaun Tanger cover the latest research in timber management.
• Working Wild University – Dr. Alex Few and Dr. Jared Beaver immerse the listener in stories at the heart of the struggle to sustain productive, resilient and connect rural landscapes and communities.
• Fish University – Dr. Wes Neal covers the latest research in fish management from the small pond to the vast ocean.

The series housed within the NRU network aim to deliver expert-based knowledge for their corresponding genre of natural resource management. The network is a partnership between the extension services at several land-grant university, including Mississippi State Extension Service, University of Florida Extension, Iowa State University Extension and Outreach and Purdue Extension. Funding for the project comes from the Renewable Resources Extension Act.

The Natural Resources University podcasts are available through the individual podcast websites, through the NRU podcast main hub or wherever podcasts are available to download.

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 meet Eastern red cedar or Juniperus virginiana, one of the most common coniferous trees in Indiana.

This evergreen tree, also known as aromatic cedar, is unique in that it has both scale-like and sharp-pointed leaves. The foliage can be soft to the touch on mature trees or be quite sharp in seedlings and younger trees. The foliage turns from green to blueish green in spring to red or brown in winter.

The red cedar features a shreddy bark on both the trunk and branches, which is gray brown in color. It is slow growing but may live longer than 450 years.

The fruit of red cedar is a small cone, which resembles and is often referred to as a berry, that is blue in color and features a whitish bloom on the surface. The fruit is preferred by birds and wildlife of many varieties and is thus spread to roadsides, old pastures and other locations with plenty of sun and disturbed soil. It can be found in forest understories, but prefers direct sunlight.

While earthworms in the spring are a happy sight for gardeners, an invasive worm species is wreaking havoc for landowners and gardeners in southern Indiana.

Robert Bruner, Purdue Extension’s exotic forest pest specialist, describes jumping worms, an invasive species to North America in the genus Amynthas: “Traditionally, when we see earthworms, they are deep in the ground and a little slimy. The jumping worms are a little bit bigger, kind of dry and scaly, and tend to thrash around much like a snake does.”

While worms have a reputation as a helpful species found in the soil ecosystem, invasive jumping worms do not live up to that standard, Bruner explained. Jumping worms will consume all organic material from the top layer of soil, leaving behind a coffee ground-like waste with no nutrients for plants or seeds.

Since jumping worms stay within the first few inches of topsoil, they are not creating channels for water and air the way earthworms do, disrupting water flow to plant roots.

“So basically, they’re just very nasty pests that ruin the quality of our soil, and the only thing that can really grow in soil like that are essentially invasive plants, or species that are meant to survive really harsh conditions,” Bruner said.

Currently, the worms are being found in cities around southern Indiana, he said, particularly in Terre Haute. There is still much to learn about jumping worms, making eradication efforts difficult. One thing that is known, Bruner said, is they aren’t a migrating species.

“This is the kind of invasive pest that is moved almost entirely through human activity. They don’t crawl superfast,” he explained. “So, when they move, that means they’re moving because we’re transferring soil, say, from someone’s plants or someone’s compost and we’re bringing them to a new area.”

Any invasive species sightings should be reported to the Indiana Department of Natural Resources at depp@dnr.in.gov or by calling 1-866-663-9684.

The Fall/Winter 2022 HEE Update newsletter is now available online. Research highlights and student news include:

• Bat Research in the News
• Thank You Danielle
• We Are Hiring
• A Second HEE Departure
• Welcome New Graduate Students
• HEE Publications

“The HEE Update” is distributed to anyone interested in receiving updates on the Hardwood Ecosystem Experiment (HEE). The newsletter includes updates of field work, media attention, committee meetings, extension events, job announcements, publications, and presentations. Anyone can receive this newsletter. If you would like to be added to the newsletter list email Dr. Mike Saunders, associate professor of silviculture, Purdue Forestry and Natural Resources, at msaunder@purdue.edu.

What is HEE?
The focus of forest science is increasingly shifting to the management of forests as complex systems rather than as simple agricultural landscapes—with a much greater appreciation for the interactive ecosystem processes. In addition, now for many forest landowners, the ecological value of their land is at least as important as the economic return. It is, therefore, vital to understand how forest management affects not only timber production, but also the overall function of forested ecosystems.

The Hardwood Ecosystem Experiment (HEE) is a long-term, large-scale experimental study of forest management and its impacts. The project was initiated in 2006 with partners including: Ball State University, Drake University, Indiana State University, Purdue Entomology, Indiana Department of Natural Resources (IN DNR), and the Indiana Chapter of the Ruffed Grouse Society.

For information about study sites, harvesting treatments, sampling design, and more, see our Project Overview and Design page and US Forest Service General Technical Report NRS-P-108, The Hardwood Ecosystem Experiment: A Framework For Studying Responses to Forest Management.
