“We need new varieties—genetic diversity.” For more than 60 years, researchers have been scrambling to develop this diversity, searching for varieties that can withstand Dutch elm disease, including a second more virulent form of the pathogen ).
“We now have seven varieties that demonstrate good tolerance,” says Marks.
The tragedy that befell one of the country’s most magnificent trees began nearly a century ago.
First described in the Netherlands in 1919, the Dutch elm fungus is carried by the European elm bark beetle, which crossed the Atlantic in 1930 in a shipment of logs purchased by an Ohio furniture maker.
Their famously arched silhouettes, which once soared in shady cathedrals of intertwining branches along countless community main streets, vanished, leaving behind barren stretches of pavement and neighborhoods stripped of beloved trees that had stood for generations. The devastation continued along the region’s riverbanks, where the elm had been an anchor species in the floodplain forests, providing critical habitat for wildlife and protecting human communities from rising waters during severe storms.
These massive trees—often 100 feet tall and more than 100 years old—stand alone in the forest now, surrounded by smaller dead and dying elms, reminders of another time.
Elms along our riverbanks will help to save an entire ecosystem of expansive floodplain forests, and generations to come will experience once more the profound beauty of these soaring trees along our city streets.
But restoring a legend, it turns out, is not for the faint of heart.
No one knows the ecology of floodplain forests better than Marks, who has spent years pulling on waders and exploring the Connecticut River watershed, often tramping through the forest understory in waist-high water.
At nearly every site he’s studied—more than 100 in all, elms are still taking root, but they are quickly succumbing to disease, never reaching the soaring heights of centuries past.
The process is labor intensive and fraught with uncertainty, demanding years of strict adherence to careful scientific methods—and endless reserves of patience.
