  • INHS Reports: Fighting the spread of aquatic invasive species in the marketplace

    Aquatic invasive species are non-native organisms that harm the environment, economy, or human and livestock health. Illinois is especially vulnerable to aquatic invaders. Harmful effects of aquatic invasive species that reside in the lake include the multimillion dollar annual cost to industry and water utilities, reduced recreational activities, and degrading native habitats. One way that aquatic invaders are introduced to the Great Lakes region is through the buying and selling of species.

  • Brown Marmorated Stink Bugs are on the Move This Fall

    An invasive stink bug species has been found in five newly invaded Illinois counties this year, according to Kelly Estes, Cooperative Agricultural Pest Survey (CAPS) coordinator in the Prairie Research Institute, University of Illinois.

  • Researchers need your brown marmorated stink bugs

    Fall is the time for many insects to start making their ways indoors for the winter. The brown marmorated stink bug (BMSB), Halyomorpha halys is believed to have been introduced from Asia and can be a pest on tress and crops. Researchers are still trying to determine the range of the BMSB and need your help. If you believe you have BMSB, we would be very interested in looking at it.

  • Invasive Plants from Water Gardens and Aquariums Must be Disposed of Properly

    When clearing out the foliage from an aquarium or backyard water garden this fall, keep water hyacinth and other invasive plants out of streams, rivers, and other waterways.

  • Be A Hero - Transport Zero campaign to stop the spread of exotic species wins award

    The Awards for Publication Excellence (APEX) are given each year by Communication Concepts to recognize outstanding publication work in a variety of fields, and one of the Illinois Natural History Survey projects was selected this year for an award. Sarah Zack, Pat Charlebois, and their IL-IN Sea Grant colleague Jason Brown were awarded in the Green Campaigns, Programs & Plans category for their work on our “Be A Hero – Transport Zero” campaign and messaging, and for the www.TransportZero.org website. The campaign is designed to show boaters, fishermen, and other recreational water users how simple it can be to help prevent the spread of aquatic invasive species between water bodies.

  • Herbivores play important role in protecting habitats from invasive species

    Researchers from the Illinois Natural History Survey and the Morton Arboretum have been examining the potential role of herbivores on the invasion of non-native plant species in diverse plant communities.

  • Moving Firewood Long Distances Can Spread Invasive Insects

    What’s in your firewood? Tree-killing insects or diseases may be hiding in or on firewood that may be transported hundreds of miles to campsites or fireplaces.

  • Asian carp image on cover of Alternatives Journal

    The carp image, taken by Thad Cook, graces the cover of the Canada's Environmental Voice - Alternatives Journal's - "Water Issue." It accompanies an article on Asian Carp and work being done by the US Army Corps of Engineers to curb their impact and keep them out of the Great Lakes.

  • Japanese Stilt Grass alert

    Japanese stiltgrass (Microstegium vimineum) was recently discovered in DuPage County in Northeast Illinois.

  • Invasive Species Workshop Trains First Detectors in Illinois

    The 2017 Illinois First Detector Workshop on invasive plants, diseases, and insects will be offered at eight Illinois sites beginning in January 2017.

  • Juvenile Bighead Carp more vulnerable to predation

    INHS graduate student Eric Sanft, presented "Vulnerability of Juvenile Asian Carp to Predation by Largemouth Bass" at the recent Midwest Fish and Wildlife meetings. His research found that bighead carp are more susceptible than other carp species to predation by largemouth bass. Read more about Asian Carp research from our Kaskaskia River Biological Station.

  • Pat Charlebois honored as Professional of the Year by Illinois Invasive Species Awareness Month Committee

    INHS Lake Michigan Biological Station's Aquatic Invasive Species oordinator, Pat Charlebois, was honored as Professional of the Year by the Illinois Invasive Species Awareness Month Committee.

  • Illinois River Biological Station director Andrew Casper discusses invasive species on WTVP

    Illinois River Biological Station director Andrew Casper and affiliate Kevin Irons were guests on WTVP's "At Issue" to discuss invasive species and their impact throughout the Illinois River watershed. A variety of invasives were discussed, including Rusty Crayfish, Round Goby, Grass Carp, Asian Carp, and Zebra Mussels.

  • Monitoring for Brown Marmorated Stink Bugs

    Illinois Cooperative Agricultural Pest Survey director Kelly Estes was asked about Brown Marmorated Stink Bugs, native to Asia, currently found in the eastern United States. Estes explained that BMSB are good hitchhikers, able to be transported by people and packages. This, and other species will be discussed during the Invasive Species Symposium this Thursday at University of Illinois.

  • 2014 Illinois First Detector Workshops for invasive species announced

    The schedule is up for the First Detector workshops for 2014. This program, a cooperative effort between University of Illinois Plant Clinic, University of Illinois Extension, and the Illinois Cooperative Agricultural Pest Survey Program (Illinois Natural History Survey, Prairie Research Institute), is a great way to learn about new pests, diseases, and plants heading into Illinois. Last year, the trainings focused on forested ecosystems; this year the focus is on Landscape and Nursery pests.

  • Native birds as biological controllers of Emerald Ash Borer Beetles?

    INHS Ornithologist Chris Whelan is a co-author on a recent publication reporting that woodpeckers may be helpful in controlling Emerald Ash Borer Beetles. Their study found that bark foraging birds, such as woodpeckers, foraged more heavily on ash trees and preferred ash trees with visible canopy decline over healthy trees. "Predation by bark-foragers significantly reduced tree-level EAB densities by upwards of 85%." The authors conclude that enhancing habitat for woodpeckers and other bark foragers may help control infestations and create more resilient forests.
