Join Trustees of Reservations Ecologist Russ Hopping on Wednesday, August 3 at 10 in the morning for a unique walking tour of Francis William Bird Park, an 89-acre reservation in Walpole, designed by renowned landscape architect and town planner John Nolen.  Russ will discuss the park’s land use history and The Trustees’ current efforts to promote biodiversity and ecological resiliency.  His passion for the sustainable landscape management practices employed here is contagious.  Attendees will learn about lawn reduction to create meadows for native pollinators, birds, and bats, sustainable mowing practices, removal of invasive species, and monitoring waterways to plan pond restoration.  Registrations are limited.  $15 for Ecological Landscaping Association and Trustees of Reservations members, or $20 for nonmembers.  For more information call 617-436-5838, or email ela.info@comcast.net.  You may register online at www.ecolandscaping.org or www.thetrustees.org.  Meet at the park, on Washington Street in Walpole.
