Overview

A variant of level bogs occurring in kettle depressions in sandy glacial outwash. Vegetation is typically zoned in rings in the peatland.

Kettlehole level bogs are a subset of level bogs that occur in iceblock depressions (commonly called kettleholes) in sandy glacial outwash. They are typically small (< 3 acres), round, and they lack inlets and outlets. Kettlehole Level Bogs are peatlands - wetlands with incompletely decomposed plant material (peat) that accumulates when saturated year round by water that is cool, acidic, poorly oxygenated, and low in nutrients. The peat isolates the vegetation from the water table, making the communities the most acidic (pH range 3 to 4), and nutrient-poor of peatland communities.
