Successes in Biocontrol – Weed Management’s Silent Hero This annual event shares the latest advances in classical weed biocontrol research with invasive plant managers and educators across North America, fostering connections between researchers and on-the-ground practitioners. This year, the Classical Biocontrol Committee will highlight the often-overlooked successes of biocontrol—stories of meaningful impact that rarely make […]

Spotted lanternfly and tree-of-heaven are closely linked invasive species that continue to threaten North American forests, agriculture and ecosystems. This webinar will explore promising biocontrol solutions aimed at managing these invasive pests. Dr. Hannah Broadley (USDA APHIS): An update on the search for and use of natural enemies to manage spotted lanternfly. Dr. Scott Salom (Virginia […]

This webinar, hosted by North American Invasive Species Management Association, will explore how the words we use to talk about invasive species can either support or undermine effective management. Drawing on insights from the Sea Grant-led Invasive Species Language Workshop hosted during National Invasive Species Awareness Week 2024, speakers will look at message framing, metaphors, […]

National Invasive Species Awareness Week (NISAW) returns February 23–27, 2026 and this year’s theme is: Defending Our Health by Stopping the Spread Invasive species don’t just harm ecosystems, they impact our water, our food systems, our communities, and our well-being. This year, NISAW will shine a national spotlight on how protecting our environment is directly […]

Small Ants, Big Impacts: Managing Invasive Ant Species in North America Invasive ants are spreading into new regions, disrupting ecosystems, impacting agriculture, and creating challenges for land managers and communities. From aggressive supercolonies to painful stings, these small invaders can have outsized ecological and economic consequences. Join NAISMA for a webinar exploring the impacts and […]

Starry Trek: Mobilizing Volunteers for Early Detection of Aquatic Invasive Species Since 2017, Minnesota’s Starry Trek Program has demonstrated how coordinated volunteer engagement can significantly expand early detection capacity for aquatic invasive species. Originally launched as a statewide effort to search for starry stonewort (Nitellopsis obtusa), an invasive freshwater green alga that can form dense […]

Amur honeysuckle (Lonicera maackii) is an invasive shrub native to eastern Asia that was widely planted for ornamental use and wildlife habitat. It is now established across much of the eastern and midwestern United States, where it forms dense understory thickets that outcompete native plants, reduce plant diversity, and alter forest structure and ecosystem processes. […]

Planning for the Unknown: Tools for Urban Forest Pest Preparedness Urban forests are on the front lines of invasive pest threats and climate uncertainty. This webinar features two practical tools that help communities assess risk, strengthen preparedness, and respond strategically to emerging forest pests. Representatives from the Washington State Department of Natural Resources will introduce […]
