The difference is that Scotland was held by private individuals in massive estates . To help pay for those estates they raise sheep 🐑 on most of the land , or well off landowners kept large herds of deer (no predators because we killed them off due to eating livestock) for occasional hunting parties. It’s the same issue Israel has , to many herd animals eating every stick before it can get a foot tall. This is a fixable issue but without any incentive to change it will not happen
