Other Invasive Species
ISN focuses primarily on invasive terrestrial plants. However, occasionally projects will shift to the surveying, management, and/or education of other regional priorities such as hemlock woolly adelgid and aquatic invasive species. Please read on for more information.

Hemlock Woolly AdelgidSince 2018, ISN has been working with partners to survey for hemlock woolly adelgid in our service area. This forest pest has the potential to be quite damaging and getting ahead of an outbreak is considered a priority in this region. As of 2024, we have been actively managing infestations of HWA in Benzie, Leelanau, and Antrim Counties.

Aquatic Invasive SpeciesAquatic invasive species (AIS) are incredibly important to manage in our lakes, rivers, streams, and beyond. ISN is lucky to have partners working directly on AIS projects within our own service area and we often defer to their expertise.
If you are curious to see some of the priority plants and animals and would like a list of additional resources, visit our AIS page, here. If you have specific questions regarding aquatic invasive species management efforts in northwest Michigan, please contact the Aquatic Invasive Species Pathways Program, based out of the Benzie Conservation District. |

Spongy MothsA spongy moth outbreak can be a frustrating event to witness, especially since they defoliate a number of different tree species. ISN currently does not manage for the moths but we do provide basic information on ID and egg mass removal.
For more information on spongy moths and how to deal with them on your own property, please visit Michigan State University's page on "Integrated Pest Management".

Spotted LanternflySpotted lanternfly is an invasive insect that has recently been discovered in southeast Michigan. Despite the small spread in the state of Michigan, we are on alert and recommend everyone familiarize themselves with what they look like. The lanternfly is especially concerning in our region because it targets fruit and ornamental trees which could greatly affect our numerous orchards, due to their feeding secretions that cause black sooty mold on plant surfaces. The preferred host plant for spotted lanternflies is tree-of-heaven, a species ISN does actively manage, however the lanternfly will choose from an array of other tree species (natives included) given the opportunity.
Visit the USDA's site for more information on this invasive insect. |
