On September 26, the New York State Department of Environmental Conservation (DEC) announced that the elm zigzag sawfly (Aproceros leucopoda) was detected for the first time in New York State at three locations in St. Lawrence County, including Wilson Hill Wildlife Management Area, Brasher State Forest, and Lost Nation State Forest. This exotic pest feeds exclusively on elm trees and can cause severe defoliation, branch dieback, and crown thinning. Although the sawfly has not yet been shown to cause tree mortality, repeated defoliation by established sawfly populations would put added stress on native elm trees already heavily impacted by Dutch elm disease.

Many people like to take firewood from their homes before traveling to a campsite. Invasive pests like the emerald ash borer or Asian long-horned beetle often hitch a ride to new areas in untreated wood. As a result, transport of untreated wood across the state has caused outbreaks of these damaging pests.
Invasive species are plants, animals, fungi, or microorganisms that spread rapidly and cause harm to other species. They are introduced species that can thrive in areas beyond their natural range of dispersal.
The mission of the New York Invasive Species Awareness Week (NYISAW) is to promote knowledge and understanding of invasive species and the harm they can cause. We want to empower YOU to stop the spread of invasive species!
Organizations across all of New York State are offering a variety of engaging events, such as interpretive hikes, volunteer days, webinars, movie screenings, and fun family activities!
By participating in NYISAW, you can help protect your community’s natural spaces, learn about new invasive species, meet your neighbors, get outdoors, and even win prizes!
The Lake George Association last week made good on its promise to explore all options for blocking the planned use of an aquatic herbicide on Lake George.
The nation’s oldest lake association – along with Lake George Waterkeeper Chris Navitsky, the Town of Hague and a shoreline resident – sued Thursday to stop the herbicide plan. In its petition, the association took aim at the process that led to permit approvals by the Department of Environmental Conservation and Adirondack Park Agency, arguing the agencies failed to consider important concerns raised by the public. The suit accuses the state agencies of “behind the scenes decision-making” to rush the plan to approval.
The Lake George Park Commission (LGPC) applied for and was granted on April 14 a permit from the Adirondack Park Agency (APA) to put the herbicide ProcellaCOR into Lake George at two pilot sites: Blair’s Bay in Glen Burnie and Sheep Meadow Bay in Hulett’s Landing. Although both sites are located on the east side of the lake, they are part of the Town of Hague, whose boundaries extend to the eastern shoreline.
Have you noticed spongy moth egg masses in your neighborhood? Last year was a boom year for spongy moth (formerly known as gypsy moth) caterpillar populations, especially in Central and Western NY. Egg masses contain 600-700 eggs each and will hatch around May. If you find them now, you can scrape them off trees or buildings and drop them into a container of detergent to prevent the eggs from hatching.
Spongy moths are non-native, but are naturalized, meaning they will always be around in our forests. They tend to spike in numbers roughly every 10-15 years but outbreaks are usually ended by natural causes such as predators and disease. Removing their egg masses is not a cure for spongy moth infestations, but it is a small step you can take to help protect trees in your neighborhood. To learn more about this species and management efforts throughout the year, visit our website.

Here in the Adirondack region, we know how special Lake Champlain is. It provides year-round recreational opportunities for residents and visitors alike and drives our local economies. It hosts some of the best fishing in the nation and is home to an abundance of wildlife. Lake Champlain provides so much to our communities, and now we need the state to step up and protect it.
Invasive species outcompete native wildlife and cause severe harm to our ecosystems and our economies. Their proliferation can lead to the extinction of native plants and animals and threaten our way of life.
Lake Champlain is facing that threat now, with the looming introduction of invasive round goby. Round goby is a small fish species native to southeastern Europe that arrived in the Great Lakes 31 years ago in a ship’s untreated ballast water. Round gobies aggressively outcompete native fish for habitat and feed on their eggs and young, harming native fisheries and local businesses.
Online Training: Adirondack Forest Pest Hunters – Surveying for HWA (Adirondack Park Invasive Plant Program – Wednesday, February 16 from 10 a.m. – 11:30 a.m.
You can help protect the Adirondacks by surveying for invasive hemlock woolly adelgid. This training will cover basic identification, survey techniques, and how to sign up for a trail to survey.
Have you seen tree of heaven plants in your neighborhood? This fast-growing invasive tree is easy to identify and found all over NY, particularly in urban areas. Tree of heaven (Ailanthus altissima) is the preferred host plant of the spotted lanternfly, an invasive insect being found in more and more parts of NY that could have severe impacts on our state’s agriculture and forests. Finding and reporting tree of heaven to NY iMapInvasives can help supplement state efforts to prevent negative impacts from these two species.
The film will be introduced by Dr. Jennifer Dean, Invasive Species Biologist with the New York Natural Heritage Program. Dean will take questions after the documentary.
Calling all hikers, xc skiiers, and snowshoers in the Saint Lawrence/Eastern Lake Ontario (SLELO) Region! Our friends at SLELO PRISM invite you to take a hike to protect the region’s hemlocks (and win cool prizes) this winter through their Virtual Hike Challenge. The challenge is running now through March 1st, and you can participate any time you get outside. All you need to do is take a hike, check a hemlock for signs of invasive hemlock woolly adelgid, and take a photo. Share a photo of your experience on Facebook with the hashtag #VirtualHikeChallenge for a chance to win prizes!
You can find more information about the challenge, including featured trails, on the SLELO PRISM website. Brush up on hemlock ID, and take a quiz to test your knowledge on the New York State Hemlock Initiative website. Happy trails!

The Hamilton County Soil and Water Conservation District closes out 2021 with the release of their Annual Report. The document details the District’s 2021 programs, projects, and events.
“The accomplishments listed in our 2021 Annual Report would not be possible without the steadfast support from our Board of Directors, the Soil and Water Conservation Committee, Association of Conservation Districts, Natural Resources Conservation Service, Hamilton County, and local organizations and agencies” said District Manager Caitlin Stewart. “Technicians Lenny Croote and Jaime Parslow, and Clerk Marj Remias provided expert and excellent service to landowners and municipalities year round.”
Highlights from the District’s Annual Report include:
Sometime in the 1990s, a mutant crayfish able to conquer and degrade aquatic systems emerged as a result of secret German experiments gone awry. The marmorkreb, a.k.a. marbled crayfish (Procambarus virginalis), is a destructive new species that first appeared aquariums in Germany. However, it’s more likely the result of too much inbreeding in captivity, rather than some mad-scientist scheme, that led to their mutation. They are now here, and your help scouting for them is invaluable.
Spotted lanternfly (SLF) is an invasive pest from Asia that feeds on a variety of plants including grapes, hops, and maple trees, posing a severe threat to New York’s forests and agriculture. SLF has been found in several locations in NY but has not yet spread to much of the state. One potential pathway for the spread of SLF is its preferred host plant, tree-of-heaven (TOH), which is already found in many locations across NY.
Volunteers like you are needed to look for SLF and TOH in your area. You can help protect NY’s agriculture and forests by knowing what to look for and how to report it to NY’s official invasive species database, iMapInvasives. Visit iMap’s website to learn about the project and sign up for a grid square on the map to look for these species out in the field.
Join iMapInvasives and the NYS Department of Agriculture and Markets for some tips on how to find these invasive species (particularly adults and egg masses), and for a recap of the incredible monitoring efforts made by volunteers across the state this year:
