Description

COPY:

CHaMP is designed as a Columbia River basin-wide habitat status and trends monitoring program built around a single protocol with a programmatic approach to data collection and management (RM&E Workgroup 2010). CHaMP will result in the collection and analysis of systematic habitat status and trends information that will be used to assess basin-wide habitat conditions. When coupled with biological response indicators, this status and trends information will be used to evaluate habitat management strategies. This program will be integrated with ongoing Pacific Northwest Aquatic Monitoring Program (PNAMP) recovery planning efforts and will be part of the collaborative process across Columbia Basin fish management agencies and tribes and other state and federal agencies that are monitoring anadromous salmonids and/or their habitat. The implementation of CHaMP will characterize stream responses to watershed restoration and/or management actions in at least one population within each steelhead and spring Chinook Major Population Group (MPG) which have, or will have, “fish-in” and “fish-out” monitoring (identified in RPA 50.6), thereby meeting the requirements of RPA 56.3, RPA 57, and RPA 3. CHaMP was designed to deliver trends in habitat indicators and requires that monitoring occurs for three cycles of a sampling panel (see section 1.6), at least 9 years.

​​The Methow sampling design adopted the standard CHaMP status and trends monitoring design, which includes a sample size of 25 sites per year with one annual and three rotating panels (sampled every three years).  The Methow Steelhead population ( Steelhead-Upper Columbia River DPS-Methow River) is the listed population of interest.

Methow initiated a GRTS based survey design in 2010 with sites selected from the CBW master sample.  Twenty eight of the 30 legacy sites fell into the Depositional Valley Class (14 public and 14 private).  This set of legacy sites is carried over into Methow’s ChaMP design. Please disregard any indication in this documentation that legacy sites were NOT used.

2012 Sample Design Notes:

There were no changes to the Methow sampling design or frame in 2012.

2011 Sample Design Notes:

The finadd.str.pnl.r function was applied to each stratum separately generated a spatially balanced ordered site list with legacy sites at the top.  A standard CHaMP temporal design was used, modified as indicated for lack of transport sites.  No sites were allocated to transport stratum because master sample indicated proportion of transport sites was < 1%.  Source stratum accounted for about 7% of total.  Approximately 92% of target domain is Depositional; site selection reflects this preponderance of Depositional domain.

Strata notes

Source-Private: No legacy sites; assigned 2 sites from ordered list to annual panel.

Source-Public: Assigned the legacy site to annual panel, then the first one on the list of non-legacy sites

Transport: No sites assigned; see comment above regarding proportion transport sites in domain.

Depositional-Private:  Assigned legacy sites as: A: 4,R1:4,R2:3,R3:3 then filled from non-legacy sites​

Depositional-Public: Assigned legacy sites to panels as follows:  A: 4, R1:4, R2:3, R3:3, then filled in with non-legacy sites

Did not distinguish legacy annual from legacy RP sites because Methow began sampling in 2010, so each site had a 1 year history
