![County Distribution Map for [SNAME]](/tmp/Species_Distributions13716595317696.png)
Updated 05/08/2013. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.
Habitat
The weed shiner was once found in open, sandy streams, river, and impoundments with submerged aquatic vegetation. In Michigan, they were found mostly in tributary junctions and below dams of major rivers. Populations were locally distributed and rare. Michigan has few river systems capable of supporting this species.
Natural Community Types
- Headwater stream (1st-2nd order), riffle
- Mainstem stream (3rd-4th order), pool
- Headwater stream (1st-2nd order), pool
- Mainstem stream (3rd-4th order), run
- River (5th-6th order), pool
Management
Habitat degradation, increased siltation and turbidity from the loss of riverine vegetation, widespread deforestation, and wetland alteration are likely reasons for the extirpation of this species (Smith 1979).
