Field Guide
All 5 species with their real drop tables, growth times and planting rules - extracted from the release game files.
Showing 5 species.
Every species grows through 4 stages; full growth takes 15 to 33 minutes depending on the tree. The loot depends on when you chop: a young tree only returns its sapling and a few sticks, a half-grown tree drops some logs, and a mature tree gives the full yield of 7-9 logs plus leaves and a sapling. Sticks only ever drop from young trees.
Every chopped tree returns a sapling. Place it on open ground - not on farmland. Alder, Birch and Maple saplings grow in any biome; Oak and Pine saplings only take root in the winter biome. Full growth takes 15-33 minutes depending on species.
Oak and Pine - the snow islands have only these two species in the wild, and their saplings can only be planted there.
Place a Forester bot: it chops mature trees and replants saplings automatically within 3.5 m of its dock. Pair it with a Transport Drone to move the logs into storage.
