Bringing Back a Lost Tree Species--the Butternut
(Originally posted at FOHW.org, the official website for Friends of Herrontown Woods)
In recent years, the Friends of Herrontown Woods has teamed up with local tree experts to bring back a little known and seldom seen native tree called the butternut. Also called the white walnut, and sporting the scientific name Juglans cinerea, its numbers have dwindled over the past fifty years due to an introduced fungus that causes canker. Just a few persist in Princeton, discovered by Bill Sachs and arborist Bob Wells. This young butternut was grown by Bill Sachs from locally collected nuts, and planted by FOHW volunteers in a clearing near Veblen House.
Maybe the local deer get their news on the internet, because soon after this butternut's photo appeared in a blogpost about Herrontown Woods, its leaves disappeared, prompting us to extend the fencing higher around the tree. Persistence and followup are everything.
These are the new shoots now protected by the fencing. Another year or two and the tree will be tall enough to survive without protection.
When Bob Wells found a butternut growing near Stone Hill Church, a neighbor of Herrontown Woods, FOHW got permission to plant a couple young butternuts near it, to provide cross fertilization. Those saplings, too, would not survive without followup, and the followup probably wouldn't happen if this wasn't a labor of love, which in this case describes whatever makes one think to take a look and see how they're doing. Leaves eaten but stem still alive.
Some chickenwire laying on the ground nearby proved handy for protecting the resprouts.
With four young butternuts at Veblen House, two in Autumn Hill reservation, two at Stone Hill Church, six at Mountain Lakes, and several more growing at TRI and in Harrison Street Park (Clifford Zink being the catalyst there), our native butternut stands a chance of making a comeback in Princeton.
