Considerations for Category Break Determination Based on relative function scores Need enough categories to be meaningful and useful in prioritization Need outliers (extreme high and low values) to be within similar groups Needs to be statistically-based
Category Break Options Explored Based on various standard deviations from the mean Based on quartiles (four equal categories) Based on quintiles (five equal categories)

Questions on Existing Conditions Analysis Example?
Repeated Process for all Habitat Groups - Wetland Analysis units were 28 sub-watersheds Seven functions advanced Surface water storage Nitrogen removal Pathogen removal Organic matter export/contribution Sediment/phosphorus removal Wildlife habitat Carbon sequestration
Wetland Habitat Group Analysis (cont.) Most functions were carried forward (exception was thermo-regulation) Altered numerous attribute measures – generally based on data availability and duplication Relative condition categories as follows: Lowest and Highest = 5 sub-watsh. each Lower and Higher = 6 sub-watsh. each Median = 6 sub-watersheds
Forest Habitat Group Analysis Analysis units were 85 forested habitat blocks based on Nahkeeta NW report Two functions were advanced Biodiversity Maintenance Habitat Creation and Maintenance Can use attribute level metrics for next project steps if necessary (numbering 3 and 2, respectively)
Forest Habitat Group Analysis (cont.) Functions were revised substantially Altered numerous attribute measures – generally based on data availability Relative condition categories as follows: Lowest and Highest = 14 habitat blocks each Lower and Higher = 16 habitat blocks each Median = 25 habitat blocks
Meadow/Shrub Habitat Group Analysis Analysis units were 46 meadow/shrub habitat blocks based on Nahkeeta NW report Two functions were advanced Biodiversity Maintenance Habitat Creation and Maintenance Can use attribute level metrics for next project steps if necessary (numbering 2 and 2, respectively)
Meadow/shrub Habitat Group Analysis (cont.) Functions were revised substantially Altered numerous attribute measures – generally based on data availability Relative condition categories as follows: Lowest and Highest = 7 habitat blocks each Lower and Higher = 9 habitat blocks each Median = 14 habitat blocks
Nearshore/ Estuarine Habitat Group Analysis used methodology in WRIA 1 nearshore assessment (CGS/Anchor 2013) Same methods as WRIA 1 analysis, but scaled to project area Methodology rated stressors, analogous to function ratings for other habitat groups EVC (Ecological Value Criteria) scores scaled to project area. Existing conditions and results presented in memorandum
Questions on Existing Conditions Analysis for Other Habitat Groups?
Questions for TAG to Consider / Answer When Reviewing Existing Conditions Are the results of the analyses consistent with your understanding of conditions in the study area? Are the attribute measures analyzed useful and weighted appropriately? Are all of the functions analyzed useful for restoration prioritization, or are some superfluous? Are there any data sources or additional metrics that would strengthen the analyses?
Next Steps Receive TAG comments on existing condition analysis Refine analysis and re-run if Required Prepare draft list of restoration actions and determine affect on each ecological function Prepare matrix tying existing conditions to restoration actions to prioritize key actions Prepare memorandum presenting results of initial (without constraints) prioritized list of actions for each analysis unit
