9:15 AM – Earthworms in Managed and Urban Landscapes: Impacts and Solutions

Dr. Olga Kostromytska, Extension Assistant Professor and Turf Entomologist, UMass Stockbridge School of Agriculture

Jumping worms have garnered a lot of interest from the public in recent years. This presentation will discuss the identification and biology of invasive earthworms in MA, and their role/impact in urban landscapes. This will include information about "crazy/jumping worm" species (Amynthas) that have many homeowners in MA and New England concerned.  Dr. Kostromytska will also share updates about current research.

10:15 AM – Break

10:30 AM – Invasive Amynthas and Metaphire Earthworms in New England Forests, Their Damage to Soils and Alteration of Nutrients

Dr. Justin Richardson, Dept. of Geosciences, University of Massachusetts, Amherst

Amynthas and Metaphire earthworms have been introduced to urban, peri-urban, and rural forests across New England. After invading a forest, they dramatically alter the structure of the soil, which then impacts the cycling of nutrients. These changes can improve soil conditions for some plants, especially non-natives, and diminish soil conditions for many native plants.
