1. The concept of a Master Sample: Lower Columbia Example An Update Phil Larsen Pacific States Marine Fisheries Commission c/o USEPA 200 SW 35 th St. Corvallis, OR 97330 Email: Larsen.Phil@epa.gov Phone: 541 754 4362

2. Spatially Balanced Sampling GRTS: Generalized Random-Tessellation Stratified design –Incorporates randomization –Is spatially balanced –Creates an ordered list of sites See: www.epa.gov/nheerl/arm for details

3. A Desirable Goal Create a design that allows and facilitates integration up front rather than after the fact. Current GRTS design allows selection of a “master” sample that can be subset to meet specific needs at a variety of spatial scales

4. LCFRB: Habitat Monitoring Key Entities Federal –5 agencies State –5 agencies Local –At least 12

5. LC Master Sample

6. Panel 1: 54 status sites (from table 8)

7. Panel 2: 18 annual sites (from table 8)

8. Lewis: 30 special interest

9. Diagonstic: 30 Germany

18. ODFW FRAME Based on 1:24 K stream layer (origin?) Trimmed by eliminating traces with < 0.6 sq. km basin size. Spawning and rearing domain defined on 1:100 K (start and end of distribution) Habitat outside spawning and rearing used 1:100 K.

19. ODFW LC Master 10240 sites Approximately 1 site/600 meters Coded by –Population –“Type”: spawning, rearing, habitat –HUC (8-digit) –General ownership –County –S-level (panels, e.g., annual, 3 yr, 9 yr,)

20. Indicators Coho spawners Coho juveniles Physical habitat Steelhead?

21. LCFRB FRAME Based on 1:24 K stream layer (origin?) ca. 3700 sites; 1/ km Coded by: –Subbasin –Tier –Gradient –EDT-Reach

23. LCFRB: Habitat Status Monitoring (p. 2) Landscape: Census/complete coverage –Watershed –Uplands/Hill slopes –Wetlands Stream Corridor: Sample survey –Channel Conditions –Riparian zone –Floodplain Water: –Quantity ? –Quality

24. LCFRB: Stratification Scheme Table 6 Ecoregion WRIA Subbasin (different from USGS subbasin?) Physiographic zone (different from ecoregion?) Stream order

25. LCFRB: Sample Type (p. 21; table 8) Survey: Status –Master sample Index: Trend –Master sample via an index stratum, e.g., Tier 1 sites Diagnostic –Master sample possible if diagnostic strata can be identified Focal: site specific project evaluation Probability vs. judgmental (or hand selected) sites

26. Stream Habitat Sampling Levels: Table 7 (p. 26) Indicator –Remote/office Reconnaissance –On the ground rapid assessment Inventory –Reach/habitat Intensive –Site Concept of Nested samples

27. Utility of a Master Sample An exploratory tool to examine different site allocations easily. A framework for an actual integrated, multi-agency state-wide or regional monitoring program.
