Almost overnight, it seems, the warm weather has brought out the spring peepers and their chorus heralding the season of rebirth. Next Saturday, April 22, is Earth Day, and there are several events coming up community members should note on their calendars.

April 15 — First up is a guided walk at Woodcock Nature Center to discover vernal pools. At 10 a.m. hear a short introduction on amphibians and how to spot them, and then go for a guided walk and search for eggs and tadpoles. Learn why these ephemeral — but important habitats — are important and how they can be conserved. Register at http://bit.ly/2nsk9mg.

April 18 — Next is a panel discussion on how to attract native pollinators — bumblebees, butterflies, moths, and hummingbirds to our backyards. From 7 to 8:30 at Wilton Library, residents can learn why we should care about this issue and how to attract these essential creatures. The program is free; register at 203-762-6334 or www.wiltonlibrary.org. It is the first of many events to encourage a “pollinator pathway” through Wilton.

April 22 — Roll up your sleeves and participate in the annual town wide cleanup from 9 to noon. Come by yourself, with family or friends, or organize a team. Clean up your neighborhood or head into town where work gloves, garbage bags and a Dumpster will be at the gazebo.

April 22 — Although not here in town, it’s worth noting there will be a free, raised-bed gardening seminar at 2 p.m., at 23 Richards Avenue in Norwalk. Sue Lavallee of Coast of Maine Soils will discuss sizing and locating a raised-bed garden, and proper watering and fertilization. Reserve a spot by emailing Reynoldsfarms@optonline.net or calling 203-866-5757.

April 30 — Closing out the month is an opportunity to plant a “pollinator garden” from 9:30 to 12:30 along the Norwalk River Valley Trail. Participants will remove invasive plants and replace them with native pollinator-friendly shrubs, trees, wildflowers, and grasses along the trail at the crosswalk on Sharp Hill Road. Bring gloves, shovels and spades, if possible. In charge are the Woodcock Nature Center and Norwalk River Watershed Association. For information, email info@norwalkriver.org or call 877-679-2463.

Since its inception in 1970, interest and enthusiasm in Earth Day has waxed and waned, but with environmental initiatives being rolled back in our nation’s capital, it is more important than ever for citizens to recognize the importance of clean water and clean air, and how we achieve them by protecting our wetlands, our local watercourses, and the rest of the natural world around us.

We must work, most certainly, from the ground up.
