Soil Sample Sites:
Our Madrona Marsh soil sample sites feature native coastal prairie (B1 and B2) and freshwater wetlands (B3 and B4), which serve as a crucial sanctuary for diverse plant life, migratory birds, and small wildlife. It consists of seasonal vernal pools in the southwest portion of the reserve in a low-lying, self-contained depression surrounded by upland coastal prairie habitat.

Coastal prairies and upland prairies differ primarily by location, moisture source, and plant composition. Coastal prairies are humid, fog-influenced grasslands found along oceans (<100 km from the coast), while upland prairies typically exist on drier, well-drained upland slopes or hills within inland, continental environments. Many coastal prairie types have rich sandy-loamy soils with high organic content, known as mollisols. Coastal prairies are among Earth’s top carbon-sequestering ecosystems, storing a majority of the carbon into the soil as opposed to vegetative tissue.

Vernal pools are small, shallow, temporary wetlands that fill with rain/snow in spring and dry up by summer, harboring no fish and unique, adapted wildlife. In contrast, freshwater marshes are typically more permanent wetlands dominated by grasses and rushes, possessing deeper water, and sustaining varied biodiversity.
