Biosequence

A sequence of soils that contain distinctly different soil horizons because of the influence that vegetation had on the soils during their development. A typical biosequence would be the prairie soils in a dry environment , oak-savannah soils as a transition zone, and forested soils in a wetter environment. Prairie soils have dark, thick surface horizons while forested soils have a thin, dark surface with a light-colored zone below.
