“…Fine sediment correlates with coarse sediment ( R 2 = 0.60 for best predictive model). CPOM correlates with coarse sediment, lateral confinement, and riparian basal area ( R 2 = 0.30 for best predictive model) (Pfeiffer, ). Although stream order does not exert a uniformly strong control on different types of material storage, it was chosen as a scale‐able way to analyze drainage basin trends in wood‐driven sediment retention (Figure S4).…”

“…Minimum drainage‐basin estimates are wood—4,164 m 3 , coarse sediment—2,742 m 3 , fine sediment—1,176 m 3 , and CPOM—419 m 3 . Pfeiffer () includes sensitivity analyses based on differing drainage area threshold values.…”

We used 48 reach‐scale measurements of large wood and wood‐associated sediment and coarse particulate organic matter (CPOM) storage within an 80 km2 catchment to examine spatial patterns of storage relative to stream order. Wood, sediment, and CPOM are not distributed uniformly across the drainage basin. Third‐ and fourth‐order streams (23% of total stream length) disproportionately store wood and coarse and fine sediments: 55% of total wood volume, 78% of coarse sediment, and 49% of fine sediment, respectively. Fourth‐order streams store ~0.8 m3 of coarse sediment and 0.2 m3 of fine sediment per cubic meter of wood. CPOM storage is highest in first‐order streams (60% of storage in 47% of total network stream length). First‐order streams can store up to 0.3 m3 of CPOM for each cubic meter of wood. Logjams in third‐ and fourth‐order reaches are primary sediment storage agents, whereas roots in small streams may be more important for storage of CPOM. We propose the large wood particulate storage index to quantify average volume of sediment or CPOM stored by a cubic meter of wood.
