Tahoe Sucker – State Wildlife Action Plan

Overview

Species Common Name Tahoe Sucker
Species Scientific Name Catostomus tahoensis

Ecoregions

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

Restricted distribution in McDermitt Creek

Limiting factors

Vulnerable to random disturbance or events that cause isolation (e.g., fire). Limited dispersal and changes in water quality and quantity under climate scenarios are of concern.

Data gaps

Degree of hybridization with Mountain Sucker.

Conservation actions

Continue ongoing recovery efforts to monitor water availability, improve riparian condition and channel structure, remove hybrids, and treat for rainbow trout (implementation of current recovery plan).
