Baseline aquatic monitoring on Santa Rosa Island shows widespread reach‑scale impairment, high salinity and watershed clustering of communities
Summary
CSU Chico researchers reported multi‑metric baseline monitoring from Santa Rosa Island, finding reach‑scale impairment at many sites, high salinity and benthic communities that cluster by watershed.
Researchers from CSU Chico and collaborators presented baseline aquatic monitoring from Santa Rosa Island (Channel Islands National Park), comparing CRAM, CSCI and habitat data across multiple sampling rounds.
The study established monitoring sites across the island and used a modified CRAM (reach‑scale components), SWAMP bioassessment protocols and CSCI calculations at resampled sites. Overall CRAM scores averaged in the mid‑70s, but the reach‑scale (bio‑phys) metrics…
