Overview

Species Common Name Modoc Sucker
Species Scientific Name Catostomus microps
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.

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Special needs

Limited to Goose Lake Basin, Thomas Creek. Requires pools and cover for spawning habitat.

Limiting factors

Relatively isolated species vulnerable to random events (habitat loss, barriers, water diversions).

Data gaps

Distribution. Population biology.

Conservation actions

This species would benefit from continued habitat restoration, and from better information on distribution, abundance, population trend, and threats.
