Mac Johnson Wildlife Area – Brockville Professional Review and Guide
"The 532 hectares (1,315 acres) of the Mac Johnson Wildlife Area include fields, forests, and wetlands surrounding a reservoir that was once known as the Back Pond, and are a provincially significant habitat of plant, animal, and bird life. Long a popular local recreation site, the property has been developed with the addition of picnic facilities, a stacked-loop trail system, an interpretive program, and a nature centre. Perhaps its most distinctive feature is its breeding pair of trumpeter swans. Their call must be heard to be fully appreciated."
