Carr is trying to find a way to preserve a centuries old Burr Oak tree and a brick barn house located on land she owns at 3348 West National Road in Englewood. Harriet and her husband Carroll donated 15 acres of woods behind Englewood's Centennial Park to the city of Englewood.

This woods, known as "Carr Woods" contains unique species of trees, including pumpkin ash, which is rarely found in Ohio. .

She is determined to preserve the Bur Oak located north of Carr Woods on a farm she owns and rents out. The mighty oak has been examined by former Aullwood naturalist Paul Knoop and Dane Mutter, who at the time was assistant director of the Montgomery County Park District as well as Scott Huston, then director of the Miami County Park District. It is estimated that the tree is between 500 to 740 years old.

The exact age could be determined by boring into the tree, but naturalists decided not to follow this procedure so that the health of the Burr Oak would not be affected.

The oak is roughly 19 feet in circumference and is still growing larger.

Current Aullwood Naturalist Tom Hissong, a lifelong Englewood area resident, agrees that the tree should be preserved as part of the area's natural history.

"The tree is significant in the fact that it is very large and has existed since before settlers came to the area," said Hissong, who fears the tree could be lost if an uncaring developer purchases the land.

"Developers will not look upon this as a historic tree. They'll probably just want to cut it down" added Hissong. "The land around it must be protected if the tree is to be preserved".

The Carrs are trying lo get the tree listed on the National Register as an historic tree, and also feel the home, which was built in 1837, should also be preserved.

Hissong agrees. He feels the home could be preserved as a historical museum detailing the history of the Englewood area. The home's location along historic National Road lends another aspect to its importance. Hissong feels its location near Carr Woods could lead to an eventual link between the property and woods.

Harriet Carr thinks the idea for a museum is valid, but she is uncertain on whether to sell or donate the property. The home and tree are situated on 58 acres. An additional 25 acres of land once part of the farm was sold and 15 acres of woods donated to the city.

Originally purchased Apr. 24, 1820, the farm consisted of 160 acres. When the farmhouse was constructed in 1837 the bricks were made right on the property. The property came into the Carr family on June 2, 1929 when Harriet Carry's father purchased it. A barn which was located on the property was built in 1849.
