The Delaware Department of Natural Resources and Environmental Control’s Division of Watershed Stewardship and the Reclaim Our River Program, in partnership with the Delaware Nature Society and the Nanticoke Watershed Alliance, will host two presentations on pollinators and gardening for clean water at 6 p.m. Feb. 19 and March 26 at the Seaford Library, 600 N. Market Street Extended, Seaford.

The presentations will focus on how the monarch butterfly population worldwide over the last 20 years has declined by 90 percent — and what can be done to halt this critical environmental loss because plants depend on pollinators like the monarch butterfly for reproducing and natural abundance. Pollinators enable flowering plants to help purify water and also help prevent erosion through a plant’s roots that hold soil in place and the foliage that buffers the impact of rain as it falls to the earth.

A limited amount of free milkweed seeds will be available to those attending the presentations. ROR partnership members will share information on activities that support clean water, said Philip Miller, DNREC Nonpoint Source Program, Division of Watershed Stewardship, while also learning about this year’s ROR-Nanticoke Series which again offers numerous opportunities to have fun around the water and learn surefire techniques for keeping waterways clean.

The Feb. 19 pollinator presentation will be given by Mike McFarlin, who raises monarch butterflies each summer in an effort to bolster Delaware's monarch population. His presentation will delve into this butterfly's migration routes and the impact humans have on the monarch’s habitat. McFarlin will also discuss his experiences looking for eggs, raising the monarch from eggs, feeding them and ultimately releasing the butterflies he raises into Delaware’s environment.

The March 26 presentation will be led by Alice Mohrman from the Delaware Nature Society’s Abbott’s Mill Nature Center and will focus on gardening for clean water and butterflies. Attendees will learn how to make a yard, deck, patio or balcony more inviting for pollinators, including birds and butterflies. Mohrman also will offer tips on landscaping, whether big or small, with native plants that support wildlife habitat while also helping to reduce pollution in waterways. She will demonstrate steps toward creating a certified wildlife habitat.
