Revisiting the Seven Sisters Oak

Though I’ve had a couple of other blog posts in the works, I couldn’t leave the 30-something project behind without a nod to the Seven Sisters Oak, the current president of the Live Oak Society and the national champion live oak tree species in the American Forests’ Big Tree Registry. And also a 30-something oak…

Cyndi and I took a drive from Bayou Lafourche to the north shore of Lake Pontchartrain recently to revisit the Seven Sisters Oak, to make some new photographs for the blog and say hello to an old friend.  The sky was overcast, making it possible a good day to photograph in the shadows of a towering old oak.  The recent rains had turned the resurrection fern a lush bright green. (We also made a stop in Ponchatoula to stock up on local strawberries and visit a couple of other local oaks including the Abbot Paul Schaueble Oak.

While visiting the tree, we met the current owners, John and Mary Jane Becker. They were welcoming and informative about their term as caretakers of this massive oak (almost 40 feet in circumference).  The Seven Sister’s Oak shades much of the front yard of the Becker’s home in the historic neighborhood of Lewisburg, near the edge of Lake Pontchartrain, in Mandeville.  Mrs. Becker remarked how the old oak was wearing an abundance of new celery green flowers (catkins) when we visited, one indication that the centuries-old tree is still healthy and vital.  She also said that last year the oak produced a bumper crop of acorns.

If you missed our previous blog post on the Seven Sisters, I’ll recap some of its known history (though what we know about the oak dates back less than 100 years and some estimates of the tree’s age put it to between 600 and 1,000 years old).

The Seven Sisters Oak is actually the second live oak to take the status of President of the Live Oak Society.  It replaced the Society’s first president, the Locke Breaux Oak, after its death from air and water pollution (see my previous posts about the Locke Breaux Oak for details).

For years, the eligibility of the Seven Sisters Oak as a society member tree was disputed.  It was argued to be several separate trees growing together rather than a single tree. Then in 1976, after inspection by federal foresters, the multiple tree trunks were found to have a single root system.  It was accepted into the Society—registered (#200)—and in time, was appointed the new Society President, based on its girth, limb spread, and height.

(A short sidebar.  From other sources, I see this is an ongoing argument among tree-measuring folks—whether the circumference of a multi-trunk oak can be compared equally to a single-trunk tree. I take a neutral position on this topic. To me, they’re all very old oaks, and as such deserve to be considered as cultural, historic, and environmental treasures, regardless of the shape or number of trunks.)

The oak tree’s first sponsor was the Doby family who owned the property on which the tree is located at that time (the 1930s). Mrs. Carole Hendry Doby was one of seven sisters in her family and the tree was named originally named “Doby’s Seven Sisters.” The oak was re-registered (#697) by its next owners, Mr. and Mrs. Milton Seiler.  The Seiler’s renamed the tree simply “The Seven Sisters.”

According to the American Forests’ Big Tree Registry, the Seven Sisters Oak has a crown spread of 139 feet, a circumference of 467 inches (approximately thirty-nine feet) and a height of sixty-eight feet. Its age has been estimated to be somewhere between 500 and 1200 years old. The current measurement is closer to 480 + inches or 40 feet.
