Substrate behaviors

Substrate is what seedlings germinate in - soil, rock, and the organic layers on top. The quality of the substrate can make a big difference in a seedling's ability to survive and establish. The substrate composition in any one place is constantly shifting and changing as new substrate is added to the forest floor and as existing substrate decays. These behaviors keep track of the substrate conditions at different locations through time.

Behavior	Description
Substrate behavior	Keeps track of six kinds of substrate: forest floor litter, forest floor moss, scarified soil, tip-up mounds, decayed logs, and fresh logs.
Detailed Substrate behavior	This behavior is a modification of the Substrate behavior that primarily incorporates greater detail in tracking log cover.
