It depends on your choices.
As per
https://permies.com/wiki/108155/pep-foraging/PEP-Badge-Foraging you need to collect 1-1 item from the lists of:
Fresh list
Dry list
Tea list
Dish list
You also must produce 4lb of seed bombs.
At first. But there is a secondary list that wants you to complete two different items from the following list:
- catch and prepare at least one pound of fish
- catch and prepare one wild rabbit or squirrel
- harvest maple sap and reduce it down to make 1 pint of syrup
- do 2 more items from the dry list (duplicates from the dry list are okay)
- do 4 more items from the dish list (duplicates from the dish list are okay)
- do 4 more items from the fresh list (duplicates from the fresh list are okay)
So actually if you choose to, you can satisfy the requirements collecting dry list elements 3 times and the ones from the fresh list 5 times.
All the above are about the sand badge. The straw is more complicated.
