Objectives Promote methods and data comparability through

improved data documentation

Identify commonalities among existing PHAB Protocols and Data Management Systems

Support ESAR/WQX teams’ effort in integrating PHAB Results and metadata into their data exchange tools

Develop a list of core data elements for PHAB, and integrate them with existing WQDE modules.

What is physical habitat?

Habitat = the set of conditions that support and control species distribution and abundance

Physical habitat = the physical structure (in this case, of streams). Includes some “biological” elements like vegetation that affect structure

Elements of physical habitat Stream size and gradient Sinuosity Substrate size and stability Habitat complexity and cover Woody debris size and abundance Residual pool dimensions and frequency Riparian vegetation cover and structure Anthropogenic disturbances Channel-riparian interaction

New data elements (cont)

6.5 Sample Collection Method 6.5.4 Sample Collection Criteria

Indicate any particular conditions that must be present in order for sample to be valid

Examples: Max. depth must be less than 1 m in order

to sample Flow velocity must be less than 0.3 m/sec Etc.

04/20/23

New data elements (cont)

7.0 Sample Analysis and QA/QC 7.9.2 Sample Batch ID

All samples collected in one trip that share field duplicates, blanks, and other quality checks for sample integrity

7.9.3 Result Batch ID All the field measurement results that share

repeated measurements and other quality checks for reproducibility, or that were collected by one instrument between a calibration and the subsequent accuracy check

Future Directions

Outreach Presentations, workshops Demonstrations

Update User Guide Incorporate new data elements Include examples for clarity Provide tools
