If the information I got is right, the staple crop growing here, and harvested since prehistory, was a wild parsnip. When potatoes were 'discovered', and came to Europe, everyone changed to potatoes. I don't understand why parsnips now are a 'forgotten vegetable' (starting to come back since a few years, mostly in the organic food stores). They grow easily, at least at my allotment garden. Better than potatoes, which get blight and colorado bugs.
i bet parsnips are an excellent one for certain climates!
The challenge as I see it, is that we are looking for calorie dense foods that stick around without attracting other critters who are also looking for calories. Nuts won’t work because they have a crazy short harvest time before squirrels and such nab them.
Honestly, I can’t think of many crops in this area that are calorie dense enough to serve as a staple and stable through the winter. Maybe ground nuts? Turnips? Persimmons - I have seen examples of the fruit drying on the tree and being edible long into the winter.
If you include crops with short harvest windows but minimal storage requirements, then hazelnuts, walnuts, and winter squash can be added to the list. And storage fruits like winter apple.
