“Yet another ground type.”
“The ground is boring.”
“Just some ground, eh?”
“A piece öf the battlefield.”
“Some ground that we dug up.”
“It's like an ingredient for the ground.”
Deciduous Turf is one of the Turf items that appears in the Reign of Giants DLC, acquired by digging Deciduous Forest tiles with a Pitchfork. Like other Turfs, it can be placed on any bare ground tile or used as fuel.
Plants like Berry Bushes, Grass Tufts, Saplings, Spiky Bushes, Lureplants, Pine Cones, and Birchnuts can be planted these Turfs. It will not also stop the Lureplants' Eyeplants from spawning.
When placed on the Surface World and the area is large enough, Crows are the only Birds that will spawn and land on these turfs.
