CARLYLE LAKE – The U.S. Army Corps of Engineers at Carlyle Lake is hosting Bring Back the Monarchs on Saturday, May 16, to commemorate National Park Trust’s (NPT) Fourth Annual National Kids to Parks Day. The event will take place at the Carlyle Lake Visitor Center from 9:00 a.m. to 12:00 p.m. Over the past two years the monarch butterfly population has reached its lowest level since 1993. Participants at the event can help the recovery by assisting with milkweed and wildflower plantings that will help provide monarchs with food, cover and host plants to lay their eggs. Other activities will include monarch programs presented by the Butterfly House, monarch crafts, and photo opportunities.
