Foraging 200,000 Calories from 10 Different Species

I'm thinking about tackling this bigger PEP BB: https://permies.com/wiki/150764/pep-foraging/Forage-Calories-Species-foraging-wood but I'm kind of a soft-core forager and so this'll take some planning. This thread is where I'll do my planning out loud and also document my actual forage so that if I meet the BB's criteria, I can just point back here.

I need to acquire 200,000+ Calories from 10+ species. 10%+ of those need to be canned. 50%+ of those need to be dehydrated to a shelf-stable point. (I can maybe satisfy this food-preservation BB at the same time: https://permies.com/wiki/150148)

For each thing that rolls up into this, I need to provide photo evidence of:
- [me] foraging each type of food
- the weight of each food on a scale (and written description of the number of calories it represents)
- [me] preparing the food to be dried or canned (if that's happening)
- [the food] dried or canned in storage

To make things more complicated, I don't eat meat, so I'm playing on hard-mode.

Now I/m wondering what I can do for this.

Maple syrup -- 10K Calories is easy -- I already have that from this season, so I just need to document it.
Birch syrup is harder -- I have more birch trees, but it takes 200 gallons of sap to make a gallon of finished syrup, so that's a lot of hauling and boiling. But it's another species, so I may need to exploit that.

Sheep sorrel -- my back-of-envelope math says any wild greens are about 30 Cals/cup, so I'd need 334 cups of leaves to hit 10K. That's clearly not possible in one year from my property so I'd have to travel or span seasons, either of which is possible.
Dandelions -- see above
Lambs Quarters -- see above
Nettle -- see above

Random seeds like dock and mustard -- these are about 346 Cals per 100g, so 2900g would hit 10k. (I think that's less than a half-gallon of seeds, so this might be possible.)

Blackberries -- I'd need ten gallons to hit 10k. That might take four or five years if I stick to my property.
Other bramble -- there are raspberries and thimbleberries all over this area and I could take a bag with me when I go hiking. I don't think I can reasonably hit 10K from one of them any short period of time, but maybe they add up or just fill in the gaps.
Apples -- there's an apple tree on a lot where they demolished the house four years ago and it was unlivable for a decade or more before that. That counts as an abandoned homestead for this BB. I'm not sure what 42 apples looks like and whether that's possible from one tree and one year. Plus, I sort of know the owners and they might not want them to all disappear. I need to keep my eyes open for others.
Tiny wild fruit -- we have serviceberries and sand cherries and pin cherries and other things like that. They're not great out of hand, but make a fine jam. Again, not sure it's reasonable to hit 10K, but maybe over time.

Hazel nuts -- I have a million wild hazel bushes. I've seen young nuts but I've never found a mature ready-to-harvest one. I have to assume the squirrels get them all. Maybe I could learn to fight them for it. Seems like I'd only need 56 oz. of hazel nut meats for 10k Cals.

I've never foraged a mushroom but that would be something to learn that would make this easier.

Seems like I need to figure out a few more sources for this to be reasonable or just be happy taking several years to reach the mark.

Ooh, 3.57 kg of sumac makes 10k Calories. That's another avenue.
Wild lowbush blueberries grow on the rocks by the St. Louis River and there are tons of trails. It's another source where hitting 10k in a year sounds crazy, but it might add up and they're super-delicious.

I don't eat meat, but I do feed it to my cats. If I could get over myself and learn to kill and butcher, I could feed my cats venison and save some industrial chickens and cows while easily marking off one more source of 10k Calories. This is probably something I'm not really going to pursue, but it's an idea. These damned deer keep eating my garden so it's stacking functions.

Do you have oak trees around or is it too cold for that?

What about wild parsnips? Caraway root?

Oh, oak...duh! Good idea. I've shelled and eaten one or two acorns fresh and they were just incredibly tannic. I'm aware that you're supposed to soak them repeatedly and whatnot, but it has always sounded like a lot of work. But this would be a great excuse to dig into that. I have three red oaks that I can see from the house and a couple more that I know of in the woods. On a good year, many, many acorns drop.

I don't know about the others. I've read you write about wild parsnips and been intrigued, but I haven't figured out if they're a thing here. And don't know about caraway -- I'll do some research.

Hello,
Are there any chestnut or walnut trees around you ?
Almonds ?
Other nuts ?
One or two adult trees might yield lots of calories.
Have a nice evening,
Oliver

More things to think about:
- Milkweed pods
- Fiddleheads
- Spruce tips
- Ramps, if I could find a patch
- Gobo/Burdock
- Ditch-lillies
- Linden (seeds and leaves)
- Black Nightshade
- Campion
- Thistles
- Cedar cones

Hi Oliver! I'm north of natural ranges of those nuts, but I brought black walnuts from my previous house and they're about five years old, and I'm planting chestnuts, which I started last year, but the squirrels dug them all up. I consider them worthy of planting and tending, but not forage. It's only an hour or two south to get into black walnut range, so I could drive somewhere to forage if I needed to.
