The Emerald Ash Borer (EAB) is an invasive insect that is killing ash trees in Jefferson County and other areas of Northern New York. For trees affected, near 100% mortality occurs within two to four years. In New York State, ash trees comprise roughly 7 to 25% of forests and is commonly used for landscaping. Whether you own or manage ash trees in an urban landscape or in a forest setting EAB will impact you. This webinar will provide you with research-based information on how to manage emerald ash borer and maintain the health of your urban forests in the path of this invasive pest.

The Hemlock Initiative has developed a decision guidance tool that generates a ranking system to help forest owners & conservation managers prioritize their hemlock stands to make an informed decision on where to focus their hemlock conservation efforts.This webinar demonstrates how to use the Hemlock Initiative’s Prioritization tool to conserve your hemlock forests. Partners who have used this tool to prioritize their hemlock stands will share their experience, and there will be an open discussion for regional and state-wide organizations to share what they are doing now to manage or prepare for hemlock woolly adelgid

In our highly urbanized world, our yards often provide vital habitats for pollinators and native wildlife. Our yards also may be a pathway in which invasive plants may escape into our natural environments. You can support pollinators and wildlife and protect natural areas by choosing to grow native plants in your yard.

This webinar discusses the power of native plants, alternatives to exotic and invasive plants, some invasive species to keep an eye out for. Nature-based community science opportunities that you can participate in right from your own backyard will also be shared.

Hemlock woolly adelgid is an invasive forest pest that is killing hemlock trees.  Hemlocks are a foundation species that benefit people and nature. Loss of hemlock trees will significantly impact our forests.

This webinar provides an overview of the importance of hemlock trees, how to recognize and report signs of infestation, and how you can help by taking a hike.

The 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 NYS forests and agriculture. SLF’s preferred host plant, tree-of-heaven (TOH), is already found in much of the state. SLF was first found in PA in 2014, and several populations have since been found in NY. Agencies and conservation partners across the state are working to protect our state resources from these invasives.

This webinar covers the current status of SLF and TOH in NY, potential impacts on the North Country, how to identify these species, and reporting observations to iMapInvasives, as well as a state-wide early detection survey effort that volunteers and professionals can get involved in.

The work that goes into managing invasive species often focuses on the treatment or removal of invasive plants and animals. But our work goes beyond the total number of acres treated or pounds of invasive plants removed; our work aims to protect the lands and waters in which we all depend on. 

This webinar showcases the unique landscapes and ecological communities that make the St. Lawrence Eastern Lake Ontario or SLELO region so special and the work that SLELO PRISM and our partners do to protect our lands and waters from the impacts of invasive species.

Hemlocks are a foundation species, meaning they often create the habitat in which they exist in. Hemlock woolly adelgid is an invasive forest pest that is killing hemlock trees in New York state and along the Eastcoast. 

This webinar provides an overview of hemlock wolly adelgid, and hemlock tree ecology. A live demo of the iMap Invasives mobile app is also provided along with an overview of how volunteers can help protect hemlock trees.

Urban forests provide immense beauty for our cities and many benefits for people and nature. Invasive tree pests and climate change threaten the health of our urban forests. This webinar focuses on a step by step approach that municipal leaders can take to make their urban forests more sustainable in the wake of invasive pests and climate change. An overview of the SLELO PRISM Urban Forest Sustainability Initiative and available resources are provided.

Prevent the introduction of invasive species into the SLELO PRISM.

Rapidly detect new and recent invaders and eliminate all individuals within a specific area.

Share resources, including funding personnel, equipment, information, and expertise.

Collect, utilize, and share information regarding surveys, infestations, control methods, monitoring, and research.

Control invasive species infestations by using best management practices, methods and techniques to include: ERADICATION (which is to eliminate all individuals and the seed bank from an area), CONTAINMENT (which is reducing the spread of established infestations from entering an uninfested area) and SUPPRESSION which is to reduce the density but not necessarily the total infested area.

Develop and implement effective restoration methods for areas that have been degraded by invasive species and where suppression or control has taken place.

Increase public awareness and understanding of invasive species.

Develop and implement innovative technologies that help us to better understand, visualize, alleviate or manage invasive species and their impacts or that serve to strengthen ecosystem function and/or processes.
