The Clark Island Wildlife Refuge and adjacent gardens will be available for a guided tour by landowners Len and Jocelyn Greenhalgh on Saturday, July 27, at 5 p.m., as part of the Georges River Land Trust’s Revelry for the River 2.

Once an abandoned granite quarry, the property has undergone a restoration and beautification project during the last 27 years, with leftover stone being used to construct more than 50 flower gardens on the site, featured in the Land Trust’s 2009 Garden Tour.

What was once a moonscape is now a 50-acre nature preserve with ponds and woodlands teeming with wildlife. Visitors will see a work-in-progress and learn about painstaking conservation efforts to conserve Maine’s precious coastal and watershed habitat.

The visit is limited to 30 participants, and tickets are available from the land trust by calling 594-5166 or order online at Tickets are $35 for members and $45 for non-members.
