The general idea is to put all species information into one place instead of splitting it between board and card stack. The info still on the board is acculturation, I will just copy that part of the board and make markers from the copy. The sheets work fine for me, maybe others will find them useful as well. I am aware that seeing predator/prey relations is easier with the original method, it is a matter of preference.
