JOHNS ISLAND (AP) — A conservation group has more time to buy 17 acres of land near the Angel Oak, a live oak on Johns Island estimated to be as much as five centuries old.

The Post and Courier of Charleston reports the Lowcountry Open Land Trust had a Sept. 30 deadline to purchase the property to help buffer the area from development.

The bank which owns the property has extended that deadline until Nov. 21.

Mike McShane of the trust has said the group hopes to get a half-million dollar grant from the State Conservation Bank, leaving about $50,000 still to be raised.

The oak is in a small park operated by the City of Charleston. Its trunk is 25 feet around and its largest limb is almost 90 feet long.
