On Thursday, Sep. 26, at 10:00 a.m., help the Nature Conservancy plant 20 disease-resistant elm trees in the Czikowsky Hill Preserve as part of the organization’s ongoing effort to reestablish the iconic American elm along our riverbanks and in our floodplain forests.  The Czikowsky Hill Preserve is owned by the Town of Lyme and the Nature Conservancy, with a Lyme Land Conservation Trust easement.  Residents who plan to attend should contact Wendy Hill, Lyme’s open space coordinator, at openspace@townlyme.org; and plan to bring heavy-duty work gloves, sturdy shoes, bottled water and, if possible, a shovel.  Parking for the outing is at Hemlocks Preserve on Joshuatown Road, just across from the end of Old Hamburg Road.
