The 1.6.10 update added a new “tangle” tree species, as well as a new biome, “Magnolia Tree”.
The first “tangled” biome, called “Mana Tree”, will only be available to players who already have the “Mountain biome” and “Tangled Tree” biomes installed.
The second biome, known as “Tanglewood”, will be added to Minecraft 1,7.1 and will be available only to those who have installed “Tumblewood”.
In addition to the new trees, the new version also adds a new minecraft object called “tree sapling”.
This new item can be harvested from trees and planted as a tree.
While the tree saplings do not have a harvestable type, they can be planted as an “artificial” tree.
