Oak Leaves generate as the canopy of oak trees — the most common tree species in the Overworld, found in plains, forests, swamps, meadows, and a dozen other biomes. The texture is a soft saturated green tinted by biome (darker in jungles, paler in plains), and the block is technically transparent for light, allowing sun to reach the ground beneath the tree. Mining without shears or silk touch destroys the leaf with random chance to drop secondary items.

The most distinctive drop is apples: about one in two hundred leaves drops a fresh apple when broken, the only natural source of this food in vanilla without trading or chest loot. Saplings drop at roughly one in twenty rate, allowing replanting after harvest, and sticks at one in fifty. Shears guarantee the leaf block itself drops intact for builder reuse — tree-shaped builds, garden hedges, and dense canopy decoration. Leaves placed by hand are flagged persistent and never decay; leaves left after the supporting log is removed within six block radius decay automatically over a few minutes.
