Landscape Therapy Workshop
See an invasive plant. Remove it. Plant a native! At Perfect Earth Project's next Landscape Therapy Workshop with the Shelter Island Green and Water Advisory Committees, we will dive deep into invasive plants and weeds--how to remove them without toxic chemicals and how to prevent them from coming back. Andy Senesac of Cornell Cooperative Extension, Shelter Island homeowner George Huhn, and Perfect Earth Project's Edwina von Gal share their wisdom.
Bring a friend--or 10! Invite your landscaper! Come with questions!

George Huhn
George Huhn is a former research scientist, pharmaceutical drug development consultant, and software developer with a B.S. in Chemistry from Drexel University and an M.S. in Engineering from the University of Pennsylvania. George and his wife Julie Brewer are working to nurture a native plant environment on their property at the corner of South Menantic Road and Smith Street. The property encloses the headwaters of Menantic Creek and contains a diverse range of ecological habitats, including meadows, woodlands, and wetlands. The area supports an important transition from freshwater, meadow, and woodland conditions toward the Menantic Creek tidal system, making it valuable for water quality, wildlife habitat, and the long-term health of the creek.
Andy Senseac
Andy Senesac worked for Cornell Cooperative Extension at the Long Island Horticultural Research and Extension Center since 1985. He earned M.S. and Ph.D. degrees at Cornell University in the field of weed science in horticultural crops. His major areas of research were developing weed management strategies for commercial horticultural crop production, landscape and turf. His program embraced an IPM approach: including investigating herbicide, biological, and cultural means of weed management. Andy has also become involved in some of the invasive plant issues confronting Eastern Long Island. Since 2022, Dr. Senesac has retired from full time employment but continues to consult on important projects. He was very involved in helping to establish the Native Grassland at the Inlet Pond County Park. He has been on the Board of Directors at North Fork Audubon Society since 2024.
