Miller Lake Lamprey – Oregon Conservation Strategy

Overview

Species Common Name Miller Lake Lamprey
Species Scientific Name Entosphenus minima
State Listing Status Sensitive

Ecoregions

East Cascades

The East Cascade ecoregion extends from the Cascade Mountains’ summit east to the warmer, drier high desert and down the length of the state. This ecoregion varies dramatically from its cool, moist border with the West Cascades ecoregion to its dry eastern border, where it meets sagebrush desert landscapes.

Special needs

Spawn in lakes. Also inhabit marshes or rivers. Adults are smaller than late-stage larvae, possibly because of difficulty finding food, yet still can spawn. Adults parasitic; potential role of reducing egg predators.

Limiting factors

Altered hydrology and flow regime. High mortality and concentration of eggs in small area.

Data gaps

Lamprey taxonomy. Species-specific habitat requirements.

Conservation actions

Implement conservation plan adopted by ODFW in summer 2005. Also, increased understanding of biology will help in identifying habitat requirements and potential conservation actions. Remove barrier on Miller Creek.
