Benthoscore: Stream Index

Count the bugs, score the stream. Benthoscore takes benthic macroinvertebrate surveys from field tally to biotic index without a signal bar in sight. Keep multiple surveys organized with site, date, collectors, reach, mesh, coordinates, season, and method context. Start with named EPA RBP 200-organism or EPA NRSA 500-organism profiles, or document a local custom method. KEY FEATURES - Multi-survey library with duplicate, archive, restore, and delete workflows - Protocol-aware target progress and record-quality checks - Searchable reference with 24 taxon profiles with identification cues and ecological traits - EPT, HBI, diversity, dominance, clinger, intolerant, and feeding-group results - Eight habitat attributes and contextual water observations - Multi-page PDF field report, analysis-ready CSV, and structured JSON evidence - Official EPA and USGS method sources in the Methods reference and report - Atomic on-device persistence, recovery backup, preserved unreadable files, and legacy migration - No account, ads, analytics, tracking, subscription, or network requirement Benthoscore does not diagnose water quality or assign a regulatory condition class. Collection, subsampling, taxonomy, tolerance, and interpretation rules vary; apply the responsible agency method before making a management decision.
