The Farm and Forest Update (i.e., give farming and forests more mechanics)

You can use a small iron tap on a living syrup tree to collect a bucket of syrup, which is a viscous, pourable liquid that is slow to move through. The tree itself would naturally come in three colors: yellow, orange, and red.

If you strip the cork tree's logs, you get an item, cork. If you craft 4 or 9 cork together, you get a block of cork. If the log is part of a living tree, it will regenerate the cork bark over time. If it's not alive, however, it will not regenerate. The cork block itself is a wood-like block with a spongey texture, but it is remarkably fireproof and blastproof.

The carob tree fertilizes the soil in a 4-block radius around its trunk. This gives a small boost to crop growth within this radius. While alive, the leaves will drop carob beans, which livestock actively seek out and eat. If the animal is young, eating the beans speeds their growth similar to feeding them.

You can inoculate a log with a mushroom, which will cause it to slowly grow mushrooms out the side. If it's a living tree, it'll continually grow mushrooms. But if it's a dead log, you'll only get a few harvests out of it. Once a log is spent, it'll become a degraded log, the log version of mossy cobble.

Different trees and crops grow a little faster or slower depending on the biome temperature. The forest biome would get a few temperature variants: warm, temperate, and cold. Depending on forest type, you'd see different frequency of trees.
