Cutting trees or pick-axing will bring them from 1/2 a mile awhile. At night, there are about 3x to 4x more.

If your mining or tree cutting. Placing a carpet of work benches every 25 m will prevent them spawning nearby. However, having 3 or more benches up can count as a base and your then subject to having a raid. If your early game, raids are only boars and neck. Easy to dispatch.

Also dwarves don't like fire. So that will deter the base ones at least.

When in black forest early, always have the rest buff active. As soon as it comes off, build a fire, hit x key to sit down next to it. 30 seconds later you have 8 minutes worth of rest buff. That will increase your stamina regen and give a 50% bonus to XP.

If your just exploring, you can try sneak mode to not get as many aggroed to you.
