You could capture wild castoroides and put them in damming pens, and if you do, put them in half water half land pens. They will dam better like that. If you put more beavers in the same pen, they will, again, dam faster. This makes a good cementing paste farm, but will also give wood, silica pearls, rare flowers, and rare mushrooms. This is quite a bit of work though. If you're not into it or don't have enough resources or a good bird, you could just find an area( most likely in or near water) that beavers are around and passively build dams. When you check them, destroy them. Resources don't respawn in the same dam they already were in to the best of my knowledge. P.S. If you tame a beaver, there is no way to let build a dam ( I've tried ?)
These things are amazing! If you find a wild one, then that’s great because you can raid it’s dam for some cementing paste. Now, if you tame one, the beaver sadly won’t make any dams. But, you can now harvest a bunch of wood with it if you put it on wandering or use a saddle. If you think it’s a bit dangerous running on the ground, let me introduce you to one of the greatest things in this game for gathering, auto-harvest. Just get an argentavis and it’s saddle, grab a tamed beaver, and go up to a tree and let the beaver hit it. ( Put on wandering for the beaver for it to work) This is way safer than being on the ground. To get way more wood, put some levels into melee and even weight if you want to. Auto-harvest also works with ankylosaurus and doedicurus.
My last tip was on the ichthyosaurus
