March 3, 2022 • Webinar 1: Wildlife Management

Managing Wildlife in Suburban Landscapes

Paul Curtis, Professor and Department Extension Leader, Natural Resources and the Environment, Cornell University

Description: Deer, turkeys, bunnies, voles, and groundhogs may be considered pesky wildlife in many suburban landscapes on Long Island. Paul will discuss management strategies to reduce economic losses and property damage, including effective fencing options, repellents, plant selection, and ways to reduce exposure to ticks.


March 10, 2022 • Webinar 2: Phytoremediation -A Plant-based Approach to Removing Pollutants

Phytoremediation Database of Plants

Stevie Famulari, Gds, Artist, Author, Professor, Principal of Engaging Green

Description: This presentation explores a database of plants and studies for use in phytoremediation ( The database is recently updated with studies and contains hundreds of plants along with information on their original study. The database is public and used by numerous people internationally as well as organizations for accessible information on phytoremediation and plants.Ways to use the database, as well as a basic explanation of phytoremediation and related terminology, and understanding the scope of decades of studies are discussed in this webinar.

Case Study: Using Industrial Hemp to Extract Soil Pollutants

Sara L. Nason, Ph.D., Departments of Environmental Sciences and Analytical Chemistry, Connecticut Agricultural Experiment Station


The former Loring Airforce Base in Maine, where the land now belongs to the Micmac nation, has soil contamination caused by fuel spills and years of chemical use for firefighting training. In 2019 and 2020, a group of concerned community members grew industrial hemp at the site in an attempt to reduce contamination levels. Sara Nason and other scientists from the Connecticut Agricultural Experiment Station assisted with measuring chemical concentrations and assessing the effectiveness of the phytoremediation. This presentation will review some initial results and discuss the benefits and challenges of community-based phytoremediation projects.


March 17, 2022 • Webinar 3: Integrated Pest Management- It Ain’t Easy Being Green

Presentation 1 - Helping Boxwood, Impatiens and Other Plants to Dodge Diseases

Margery Daughtrey, Plant Pathologist, LIHREC, Cornell University

Description: Margery will review the latest research on several important perennials and woody plants. The following will be covered:impatiens downy mildew and boxwood blight (using resistant varieties to beat disease); early studies on beech leaf disease and how the BLD nematode contrasts to foliar nematode; aster yellows on echinacea and other herbaceous perennials and its management; white smut on dahlia, gaillardia and eryngium and its management; leaf spots of all shapes and sizes on woody plants and their chemical and cultural management.

Presentation 2 - Invasive Pests Here and There, Plus an Update on Research and the Cornell Guidelines

Dan Gilrein, Extension Entomologist , CCE-Suffolk

This presentation will review the status of some invasive pests and suggested management for 2022 –threats they pose, what to look for, and some options on how to respond. Expect spotted lanternfly to be appearing more around Long Island, winter moth shows signs of increasing in the area, and box tree moth is in western NY but may start appearing as well.The presentation will also cover results or recent work at LIHREC and some updates appearing in the 2022 Guidelines.


March 24, 2022 • Webinar 4: Ornamental Invasive Species Awareness

Presentation 1- How Well Do You Know Your Invasive Plant Regulations?

Mina Vescera , Nursery/Landscape Specialist , CCE-Suffolk

Description: Prohibited, regulated, conditionally exempt cultivars, the Do Not Sell List: what does it all mean and how does it affect your landscape designs? This presentation will offer a refresher on the prohibited and regulated invasive plant regulation for NYS, the Do Not Sell banned plants for Suffolk and Nassau Counties, and updates on potential additions to the NYS regulation.

Presentation 2- Emerging Ornamental Invasive Species

Haley Gladitsch, Invasive Species Specialist , LIISMA
Abby Bezrutczyk, Field Project and Outreach Coordinator

Description: The team at the Long Island Invasive Species Management Area (LIISMA) will discuss identification and management techniques of emerging ornamental invasive plants. The things we love about many of these plants—fast growth, abundantly beautiful fruits, and pest resistance—can also give them their invasive advantage. This presentation will inform you of the next generation of non-native ornamentals that are showing signs of invading the region’s natural areas.


March 31, 2021 • Webinar 5 – Landscape Ecology

Landscape Ecology - Designing for Habitat, Resilience and Beauty

Amanda Furcall, Landscape Ecologist, Sisters of St. Joseph Brentwood

Description: What is Landscape Ecology?Amanda Furcall answers that question and shows how it can be used to benefit the environment, while providing the aesthetic customers desire.Blending ornamental and ecological landscape design is what Amanda Furcall does every day on the 200-acre Sisters of St. Joseph campus.The site includes the full range of design needs, from historic buildings to pristine woodlands and everything in between.Through these diverse projects she will highlight principles of landscape ecology and show how they can be integrated into any design.

Encouraging Beneficials in the Landscape

Tamson Yeh, Pest Management & Turf Specialist, CCE-Suffolk

Description: Managing pests naturally is a year-round effort. Minimizing pesticide use and enhancing habitat is a primary approach to ecological landscaping. The dormant season can provide valuable habitat for beneficial insects, and you don’t need to have a “wild” garden to achieve this. Participants will learn about the overwintering sites and strategies for various insects, weeds, and diseases commonly found in gardens. You’ll learn pest management strategies to reduce overwintering pests while fostering natural pest management.


Currently, no in-person viewing at the CCE Education Center is being offered because of Covid-19 precautions.
