Aquatic Vegetation Control aka Weed harvesting Summer 2022

Aquatic Vegetation Control (AVC) is a form of nutrient management that is one of several management techniques used to manage non-point source water pollution that is natural but also impacts a balanced ecosystem for water quality. Selective harvesting invasive species and some high concentrations of water weeds verses letting them die off and fertilize seedbeds within a waterbody does three things for the environment:

      1. Removes nutrients from waterbody in specific areas to prevent high growth of stronger weeds;
  1. Reduces the potential for continuous spread of some highly invasive aquatic weeds like Water Chestnut;
  2. Increases flow from the outlets of streams into the waterbody to allow for regular movement of water thus preventing algal blooms.

There are other benefits to this management technique which include pathways for boaters to navigate into open waters, pathways for fisherman to access weed-beds for better fishing and better ascetics for the community. The District’s Aquatic Vegetation Control program subcontracted by Wayne County, began on June 13th and will provide 1 service to specific areas in 2022 through September 9th. The tentative schedule has been posted but is subject to change based on technical review weekly by the staff for addressing water quality impairments. Further schedule updates can be found on the District’s website.

The New York State Hemlock Initiative

The New York State Hemlock Initiative represents the efforts of scientists, natural resources professionals, and New York residents united in their love for hemlock trees and dedication to hemlock conservation.

In the past three months, volunteers have recorded a flurry of new observations of Hemlock Woolly Adelgid (HWA) across our region. In 2023, volunteers have recorded 28 confirmed observations of HWA, and 18 non-detections of HWA, for a total of 46 observations. Some of these observations were made in under-surveyed locations as well, such as Broome, Madison, and Chenango counties. These observations have made measurable impact on our understanding of HWA in the Finger Lakes. With this additional data, land managers in our region can better prioritize resources towards those new infestations, knowing they have time to get to the eastern counties. But what land managers are we talking about

The U.S. Department of Agriculture (USDA) is responding to a significant plant health threat and needs your help. During the spring, a number of U.S. nurseries received potentially infested Canadian boxwood plants with Box Tree Moth. If you purchased any boxwood plants this year/during spring 2021, please inspect them for signs of the moth and report any findings to our local USDA office or State agriculture department. Please inspect boxwood plants and report any findings to our local USDA office or State agriculture department. https://www.aphis.usda.gov/aphis/ourfocus/planthealth/ppq-program-overview/sphd/new+york  —by doing this now it can prevent the moth from infesting America’s boxwoods!

Box tree moth, Cydalima perspectalis, is a destructive pest of ornamental boxwoods (Buxus spp.) in Europe, where it was introduced from Asia. It was first discovered in North America in Toronto, Canada, in the fall of 2018. It has not been previously found in the United States. Unfortunately,  infested shrubs have been showing up at New York State nurseries during spring 2021, despite being inspected and confirmed as free of boxwood tree moth by the source.

The New York State Department of Agriculture and Markets (AGM) is asking for the public’s help in combatting the Spotted Lanternfly (SLF)

With Population Spreading in New York City Area, Department Asks Public to Destroy or Use Control Measures to Treat Spotted Lanternfly
Encourages Residents to Report New Sightings The New York State Department of Agriculture and Markets (AGM) is asking for the public’s help in combatting the Spotted Lanternfly (SLF), an invasive pest from Asia.  First found in New York State on Staten Island in August 2020, the population has now been observed in all NYC boroughs.  SLF (see photo below) is a destructive pest that feeds on more than 70 plant species, including tree-of-heaven, and plants and crops that are critical to New York’s agricultural economy, such as grapevine, apple trees, and hops.

State Agriculture Commissioner Richard A. Ball said, “The Department has been working diligently to mitigate the impacts of this destructive pest, which can weaken plants and have a devastating impact on agriculture.  Despite intensive surveys and the implementation of targeted management plans, AGM has continued to find SLF around the New York City area.  We are once again asking for residents’ help, this time with spotted lanternfly control measures, particularly in this area.  Outside of NYC, we’re asking for the public to continue to be vigilant and report any sightings to help slow the spread of this invasive.”

New York City Region

NYS AGM has been receiving increased reports of SLF in the five boroughs of New York City since early this month.  While inspectors continue to survey and respond to these reports, AGM is asking residents to destroy SLF adults. Later in the fall the public can help further by scraping off and destroying SLF egg masses. The public can also reach out to Cornell University’s Integrated Pest Management Program (IPM) to learn about control measures or a certified pesticide applicator for treatment options to help combat SLF. Because NYSAGM is aware of the population spread, it is asking NYC residents to forgo reporting sightings of SLF at this time.  In addition to reaching out to Cornell, AGM encourages the public to thoroughly inspect vehicles, luggage and gear, and all outdoor items for egg masses and adult SLF before leaving the New York City region.

While these insects can jump and fly short distances, they spread primarily through human activity. SLF can lay their eggs on any number of surfaces, such as vehicles, stone, rusty metal, outdoor furniture, and firewood. Adult SLF can hitch rides in vehicles, on any outdoor item, or cling to clothing or hats, and be easily transported into and throughout New York.

Residents can also help by allowing surveyors access to properties where SLF may be present.  Surveyors will be uniformed and will always provide identification.

Upstate New York

SLF has also been detected in several isolated areas upstate, including Ithaca, New York; however, that population is relatively small and scheduled for treatment.

For residents living outside of New York City, AGM urges New Yorkers to report sightings of the SLF, using the web reporting tool found here: https://survey123.arcgis.com/share/a08d60f6522043f5bd04229e00acdd63

Reporting in Upstate New York is critical, helping inspectors identify any newly impacted areas.

Brian Eshenaur, Sr. Extension Associate at Cornell University’s NYS Integrated Pest Management Program, said, “In New York, we’re particularly concerned about the impact Spotted Lanternfly could have on our grape and wine industries. Our NYS Integrated Pest Management Program has been working with our colleagues in Pennsylvania over the past few years to learn from their experience and prepare our growers for this insect advance.  We are currently scouting vineyards and have NYS appropriate management options available for producers and tips for residents as well.”

In February of this year, the State also launched an innovative effort to combat the spread of SLF in New York State. A new online interface allows volunteer members of the public to assist in surveying for SLF in a specific area, or grid of land, and tracking associated data. The program encourages broader surveying for SLF and increased public awareness of this invasive pest.

The State is holding a series of training webinars to educate volunteers on how to identify SLF and tree-of-heaven, a plant that SLF commonly feeds on. Each training webinar will focus on a different life stage of SLF based on the time of year that stage would be most likely found during survey.  Currently, the training focuses on identifying adult SLF. The training will also cover how to use iMapInvasives, how to sign up for a grid and track data, and details about land access. The next webinar will be held on October 27, from 1:00 p.m. to 2:30 p.m. More information about the program, including upcoming webinars, can be found at https://www.nyimapinvasives.org/slf.

Spotted Lanternfly Devastating to New York Agriculture

SLF feeding can stress plants, making them vulnerable to disease and attacks from other insects. SLF also excretes large amounts of sticky “honeydew,” which attracts sooty molds that interfere with plant photosynthesis, negatively affecting the growth and fruit yield of plants, devastating agriculture and impacting forest health.

The estimated total economic impact of invasive insects in the US exceeds $70 billion per year, and if not contained, the SLF could have an impact to NYS of at least $300 million annually, mainly to the grape and wine industry.

SLF also has the potential to significantly hinder quality of life and recreational activities due to the honeydew and the swarms of insects it attracts.

First discovered in Pennsylvania in 2014, SLF has since been found in New Jersey, Maryland, Delaware, West Virginia and Virginia. Given the proximity to the Pennsylvania and New Jersey infestations, New York State is at high risk for infestation.

Since 2017, AGM, the New York State Department of Environmental Conservation, New York State Office of Parks, Recreation and Historic Preservation, New York State Department of Transportation, and New York State Thruway Authority have taken an aggressive approach to keeping SLF from establishing in New York State, conducting surveys of high-risk areas across the State; inspecting nursery stock, stone shipments, and commercial transports from quarantine areas; and launching a comprehensive education and outreach campaign to enlist the public’s help in reporting SLF.

Identifying SLF

Adult SLF are active from July to December. They are approximately one inch long and half an inch wide at rest, with eye-catching wings. Adults begin laying eggs in September. Signs of an SLF infestation may include:

  • Sap oozing or weeping from open wounds on tree trunks, which appear wet and give off fermented odors.
  • One-inch-long egg masses that are brownish-gray, waxy and mud-like when new. Old egg masses are brown and scaly.
  • Massive honeydew build-up under plants, sometimes with black sooty mold developing.

Time to Check for Hemlock Woolly Adelgid

Winter is the best time to look for evidence of an infestation. Cooler temperatures trigger feeding activity, and as the hemlock woolly adelgids feed, they secrete a white, waxy material that creates ovisacs. The presence of these small, round, white masses makes it possible to identify infested trees. As they feed, these tiny, soft-bodied insects consume a hemlock’s stored nutrients, slowly sucking the life from the tree.

The eastern hemlock (Tsuga canadensis) is one of the most important tree species in our region. These trees cast the most shade of any native tree species, and a hemlock canopy creates unique environments that many other species such as brook trout rely on. Hemlocks also tend to grow on the cliffs of many of the gorges around the Finger Lakes. If we lose hemlocks, it becomes increasingly likely that these cliffsides will collapse and alter many of our waterways. By protecting hemlocks, not only are trees themselves protected, but also the organisms that rely on them for habitat.

The Finger Lakes PRISM is launching its annual Hemlock Woolly Adelgid (HWA) Survey and they are looking for clubs and individuals to help them out. The 2022 was a pilot year for the HWA Survey and it was a great success. Across 12 events PRISM trained and recruited 181 people to scour for HWA across our region and recorded over 80 observations. For 2023, they would like to build upon the progress!

What is the FL-PRISM HWA Survey?

FL-PRISM created the survey to find new populations of HWA in the region and help prioritize control measures where hemlocks can still be saved. They train volunteers on what hemlock woolly adelgids are why they are a threat. Once trained they are lead them on a guided hike to find HWA. If left unchecked, HWA threatens to wipe out the eastern hemlock, one of our most important native tree species.

What would working with the HWA Survey look like?

The process for the HWA survey is simple. Your organization will set up a date with the Finger Lakes PRISM where they will deliver a presentation (can be over zoom, in the field, or at an event space) and then lead volunteers to search for HWA on local hemlock trees. The entire process usually runs about 2 hours. They are open for scheduling training events with partners on weekdays or weekends from January 4th to the end of April (with the exception of 2/16-2/19 and 3/10-3/20).
