  1. 1. 3/9/2012Pacific Lamprey Monitoring and Data Management Yakama Nation FRMP Pacific Lamprey Recovery Project
  2. 2. Project GoalsThe goal of the Yakama Nation is to restore naturalproduction of Pacific lamprey to a level that willprovide robust species abundance, significantecological contributions and meaningful harvestthroughout the Yakama Nations Ceded Lands and inthe Usual and Accustomed areas.
  3. 3. Pacific Lamprey Adult Counts
  4. 4. Premises• Yakima population is functionally extirpated• Our goal is to have hundreds and thousands of juveniles  Supplementation a much needed tool• Genetics (risk management approach)
  5. 5. Monitoring Projects• Adult passage (radio telemetry)• Juvenile passage (Prosser Dam) -> index?• Juvenile present/absence (including canals)• Juvenile index sites (“relative abundance”)• Water quality impacts on lamprey (adult/juv.)• Artificial propagation and rearing (methods, feed)• Supplementation effectiveness (survival and growth)
  6. 6. Juvenile Surveys• Exploratory Survey (Min. Data)  Presence / Absence  Quick survey• Index Survey (Core Data)  Relative abundance  Annual variation• Extensive Surveys (Optional Data)  Release from art. prop.  Seasonal variation  Growth, distribution, habitat use
  7. 7. Focus• Need a method to measure “relative abundance” of larvae  Time & Space  Consistent & Coordinated  Precision not important  Density can be misleading
  8. 8. = Type 1
  9. 9. Intrinsic Potential (IP) Model for Pacific Lamprey 1.2 1• What is the potential 0.8 0.6 0.4 for lamprey habitat? 0.2 0 0 50 100 • Flow Mean Annual Stream Flow (cms) 1.2 • Gradient 1 0.8 0.6 0.4 • Valley Width 0.2 0 0 5 • (Temperature) Channel Gradient (%) 1.2 1 0.8 0.6 0.4 0.2 0 0 5 10 Calibrated Valley Constraint
  10. 10. Use Existing Data• Flow • >14 cfs ODFW Steelhead Survey• Gradient • <2%• Valley Width • > 100 ft
  11. 11. Benefits of IP Model for Pacific Lamprey• Higher efficiency in predicting lower and upper distribution• Make comparison of density and relative abundance more meaningful
  12. 12. Spatial Scales• 3 spatial scales • 10 M: density, habitat features • 100 M: relative abundance, status and trend • 1000 M: abundance estimates, status and trend, limiting factors
  13. 13. Legend Index Sites Extensive Sites Reach D Analysis Unit 3 Exploratory Sites Reach C Reach EReach A Reach B Reach F Analysis Unit 2 Analysis Unit 1
  14. 14. Index Sitesdensity measurements in representativehabitat types -> “relative abundance”• ~100 meters Area• 3-5 plots, fixed and mapped Supplemented• Each Plot = X amount of area surveyed over Y amount of time (~10 m)• Long-term Extensive Sites growth, survival and habitat preference of released propagated larvae. • ~100 metes • Extensive area surveyed • Location may vary over time
  15. 15. How to Calculate Abundance?? = 250 m2• Estimate area for Type 1 & 2 Habitat (using habitat surveys)• Not always available (Larger streams/rivers)
  16. 16. Core DataReach Scale (~1000 m)• Watershed (HUC 5 or 6)• Stream Name• GPS• (River Mile -> identifier)• (Elevation)• (Gradient)• (Sinuosity)
  17. 17. Core DataHabitat Scale (~10 m)• Channel type (riffle, glide, pool)• Habitat Type (% Type 1 & 2)• Plot size• Method (E-fishing, hand net, etc)• Survey time (cpue)• Time of day• Visibility (high, medium, low)• (Conductivity)• (Temperature/DO/pH)• (Riparian / % cover)
  18. 18. Biological Core Data• Species (at least %)• Life stage• Counts• (Length)• (Weight)
