Polson Loess Bluff Prairie

Polson Loess Bluff Prairie is a protected conservation area in Missouri. It preserves a rare loess bluff geological formation together with its associated prairie flora.

Loess is fine wind-deposited sediment, usually dominated by silt. At Polson Loess Bluff Prairie, the bluff geology helps create habitat conditions for a distinctive plant community.

The area protects both a rare geological feature and the plants associated with it. Conserving the bluff and its vegetation keeps the relationship between landform and habitat intact.

No, its defining feature is a loess bluff rather than a completely level grassland. The unusual landform is part of what makes the conservation area botanically and geologically notable.
