Freshwater Mussels Research
and Restoration
Confederated Tribes of the Umatilla Indian Reservation
By
Project Lead: Jayne Brim-Box
Assistant: Christine O’Brien
Project 2002-037-00
Long-term Goal:
Restore Mussels to Umatilla & other mid-Columbia rivers.
Phase I: Collect Biological Information and Physical Data.
(completed - ongoing)
1. Surveys of distribution and status on Tribal lands
2. Taxonomic issues.
3. Host fish information.
4. Knowledge of habitat controlling distribution and abundance.
5. What do mussels contribute to our rivers?
Phase II: Restoration and Monitoring (proposed)
1. Reintroduction using translocation and augmentation
2. Monitor restoration actions
Why Freshwater Mussels?
1. Most endangered faunal group in the world.
2. Western mussel populations are in decline. Many populations
extirpated from streams and rivers on Tribal lands.
3. Five of eight Western US species described from areas on or near
CTUIR ceded lands.
4. Importance to Tribes as food resource, cultural resource, etc.
5. CTUIR’s First Foods approach “brings attention to species and
linkages (ecological processes) that may be largely unrecognized and
sometimes devalued outside the reservation.”
6. Increasingly clear mussels provide valuable ecosystem services
(e.g., benefit Pacific lamprey populations).

Why so few in Umatilla drainage?

Why so few? Did they occur there historically?

Phase I. Objective 2 - Genetics.
Collect baseline genetic information to inform management
and restoration efforts
Local genetic questions:
•What species of Anodonta is in the Umatilla currently?
•What populations should be used for translocations?
•What populations are genetically most similar to this region?
•Where are the genetic dividing lines, especially in Anodonta?
A. wahlametensis
(type specimen)
A. nuttalliana
(type specimen)
Same species? How do we find out?

Does genetic subdivision in western
Anodonta reflect current species
designations in Anodonta?
NO! Three major groups exist; these may be
different GENERA (12-14% sequence
divergence!)
1. A.californiensis/nuttalliana
2. A.oregonensis/kennerlyi
3. A.beringiana
Compare patterns of genetic variation in two
mussels occupying a common landscape:
1) Anodonta californiensis/nuttalliana clade
2) Margaritifera falcata

Drivers
• habitat quality/size
• host fish ecology
• habitat stability
• hermaphroditism
• connectivity &

• generation time
• population size
• drainage history
Other Drivers
• mutation rate
• time

Genetic Summary:
• Species occupying a common landscape may have very
different phylogeographic and population genetic patterns
• Possible contributors to landscape genetic differences:
- host fish dispersal
- longetivity
- hermaphroditism
- postglacial expansion timing

Phase I Objective 5 - Mussel Contributions
--from Vaughn and Spooner (2006) and Limm and Power (2011)
Decrease phytoplankton biomass and total P and increase water clarity
Increase biodeposition of nutrient-rich feces and pseudofeces to the streambed
(food for other macroinvertebrates)
Burrowing increases sediment water content, homogenization and depth of O2
penetration (benefits Pacific lamprey).
Shells provides habitat for other benthic animals and plants.

Salmon
Conclusions to Phase I:
1. Surveys of distribution and status on Tribal lands
- Common some places, extirpated in others.
2. Taxonomic issues.
- New genera and species to be described (E&T issues).
3. Knowledge of factors controlling distribution and abundance.
- New data mining, model built
4. Host fish information.
- Fish species identified for two genera, work on-going
5. What do mussels contribute to our rivers?
- On-going work in Umatilla River and other basins
Phase II – Objective 1 – Restoration and Monitoring
Pilot relocation efforts in the Umatilla
144 Margaritifera falcata relocated into Umatilla River near
gauging station above Meacham Creek in August 2008.
Monitor: movement, growth, water variables, nutrients,
algal growth, etc…
Phase II Objective 1
Restoration and Augmentation Approaches
1. Translocation
2. Augmentation using host fish
3. Augmentation using propagation
Phase II Objective 2
Long-term monitoring of
restoration actions
“These Gonidea show very highly synchronous growth and unusually strong
relationships to climate, which indicates that they may serve well as a long-term
ecological indicator of climate and the state of the river ecosystem.”
