read email from Ashley about things being counted differently for 2024 (and maybe also 2025)

Also, the SFM site in our Gate creek study was added to our fire project in 2023 (BayLee named it SFGate or something), but we do have data for macros and many other parameters going back to 2021 (Gate Creek Study) if you want to include that in overall dataset summaries. The NF Gate site they added is not at the same location as our NF sites from that study though.

HBI = Hilsenhoff Biotic Index– estimates the overall tolerance of the community in a sampled area, weighted by the relative abundance of each taxonomic group (family, genus, etc.). Organisms are assigned a tolerance number from 0 to 10 pertaining to that group’s known sensitivity to organic pollutants; 0 being most sensitive, 10 being most tolerant.

CG=Collector-Gatherer; CF=Collector-Filterer; PH=Piercer-Herbivore; PR=Predator; SH=Shredder; SC=Scraper; UN=Unknown

What is: %DomTaxa??,

Things to test: Could earlier years have stronger correlations between fire metrics and senstitivity metrics?? Aka are things recovering over time.

Sediment Indices: BTSI FSBI BSTI (Benthic Sediment Tolerance Index) and FSBI (Fine Sediment Biotic Index) FSBI scores = statistically calibrated to sediment gradients BSTI scores = often literature- or expert-based

FSBI=∑(ni × si)/ ∑ni ni = number of individuals, si= fine sediment tolerance score for taxon. BSTI=∑(ai × ti)/ ∑ai ai = abundance, ti= sediment tolerance score for taxon.

We do have a stronger and stronger trend with BSTI (it is wrong in this file as BTSI) in years 3 and 4. The BSTI was specifically developed for Oregon (Hubler et al. 2016) the FSBI was developed for PNW (but most data from WA). “macroinvertebrate assemblages in more extensively burned watersheds shifted toward taxa more tolerant of fine sediments (higher BTSI) by the 3rd year post-wildfire”- Joe’s interpretation.

Merge with site details.

Metric tests! Make a correlation matrix to focus on the site detail metrics versus all of the indices.
