I think I read that, too. Makes some sense since among the trees in the northeast it is the only one that produces an edible mast crop. Definitely better than acorns.
The northeast has quite a variety of mast crops: Shagbark hickory, black walnut, butternut, beech (my favorite roasted but very small) and to a lesser extent hazelnut. But in its time the chestnut was by far the most consistent and prolific producer.
And an honorable mention to black cherry, a tree of the region with edible fruit.
Funny, in CT we had a bunch of these in our yard, but they never bore any fruit in our yard. We had some in Walla Walla where I went to college that would make so many you eat cherries for every meal for weeks.
Wow! Not every day that Walla Walla makes HN. Yes we have lovely trees here. There are several chestnut trees in the public parks, and I've long been curious to know if being in the west whether these trees avoided the blight, or are a different variety of chestnut.
