In my experience there has been an adjustment to prior spawn amounts, frequencies and locations. In the location (on 2 separate map seeds) where I built my main base, just over 1 year ago, there were a few boar and deer spawns along with greylings, greydwarves and skeletons. I placed a few packs of 2 star wolves around the outside of my defences and for the first 6 months or so I was occasionally feeding them. Around March of 2022, not only did the frequency of all the aforementioned creatures spawn rates increase, but the locations of where they spawned increased. I am not exaggerating when I say the deer were literally respawning behind me after killing them. It got to the point where I no longer fed my wolfpacks and had to cull them constantly.

I remember when I first started I often had to wait a game day or two for the boar & deer outside my defences to respawn in the location I had marked on my map. Now they respawn repeatedly throughout the day in many more locations than they used to.
