Northern Roach – State Wildlife Action Plan

Overview

Species Common Name Northern Roach
Species Scientific Name Hesperoleucus mitrulus

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

Confined to southeastern Oregon and Northeastern California.

Limiting factors

Habitat loss from agricultural uses and degradation from grazing riparian areas.
Degraded water quality.
Vulnerable to stochastic events due to small isolated populations that lack capacity for recolonization.
Water quantity due to withdrawal and drought.

Data gaps

Understanding abundance and distribution, monitor populations.

Conservation actions

Habitat restoration aimed at improving water quality.
