Pacific Lamprey Monitoring and Data Management

1. 3/9/2012 Yakama Nation FRMP Pacific Lamprey Recovery Project Pacific Lamprey Monitoring and Data Management

2. Project Goals The goal of the Yakama Nation is to restore natural production of Pacific lamprey to a level that will provide robust species abundance, significant ecological contributions and meaningful harvest throughout the Yakama Nations Ceded Lands and in the Usual and Accustomed areas.

3. Pacific Lamprey Adult Counts 1.6% Desperate Times, Desperate Measures

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. 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. 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. Focus • Need a method to measure “relative abundance” of larvae • Time & Space • Consistent & Coordinated • Precision not important • Density can be misleading

8. 15 or 20? More Important Question: 15~100? 100~500? 500~1000? 15

9. = Type 1 50/m2 Is 50/m2 better than 15/m2? 15/m2

10. 15/m2 15/m2

11. Intrinsic Potential (IP) Model for Pacific Lamprey • What is the potential for lamprey habitat? • Flow • Gradient • Valley Width • (Temperature)

12. Use Existing Data • Flow • >14 cfs • Gradient • < 2 % • Valley Width • > 100 ft ODFW Steelhead Survey

13. Benefits of IP Model for Pacific Lamprey • Higher efficiency in predicting lower and upper distribution • Make comparison of density and relative abundancemore meaningful

14. 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

15. Legend • Index Sites • Extensive Sites • Exploratory Sites Reach D Analysis Unit 3 Reach C Reach E Reach A Reach B Reach F Analysis Unit 2 Analysis Unit 1

16. Index Sites • density measurements in representative habitat types -> “relative abundance” • ~100 meters • 3-5 plots, fixed and mapped • Each Plot = X amount of area surveyed over • Y amount of time (~10 m) • Long-term Area Supplemented • Extensive Sites • growth, survival and habitat preference of released propagated larvae. • ~100 metes • Extensive area surveyed • Location may vary over time

17. How to Calculate Abundance?? = 250 m2 • Estimate area for Type 1 & 2 Habitat (using habitat surveys) • Not always available • (Larger streams/rivers)

18. Core Data • Reach Scale (~1000 m) • Watershed (HUC 5 or 6) • Stream Name • GPS • (River Mile -> identifier) • (Elevation) • (Gradient) • (Sinuosity)

19. Core Data • Habitat 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)

20. Biological Core Data • Species (at least %) • Life stage • Counts • (Length) • (Weight)
