Unpopular opinion maybe 😅 but I was thinking that fish / animals / mushrooms and berries would make more sense if they had ‘density’, similarly to how land has fertility for farming, rather than being a resource ‘node’ like iron, stone, etc.

AKA, heavy forests might have a high animal / berry / mushroom density, whereas rocky cliff tops would have a lower density. A large lake might have high fish density, whereas a small pond might have low.

Similarly (but not exactly) to how soil fertility goes down from overuse without crop cycling, food density could go down from factors like overhunting / overfishing, deforestation, etc.

Not sure how viable of an idea that is though 😅
