Brook & Craft

Stream Macroinvertebrate Monitoring Last updated: June 2026

Brook & Craft is a documentation resource focused on the use of benthic macroinvertebrates as indicators of water quality in Polish inland waters. The content covers field sampling methods, laboratory procedures, biotic index calculations and the regulatory context established by the EU Water Framework Directive and its Polish implementation.

Scope

Coverage is limited to freshwater macroinvertebrates — primarily insects (Plecoptera, Ephemeroptera, Trichoptera, Diptera, Coleoptera), crustaceans (Amphipoda, Isopoda) and oligochaetes — in wadeable rivers and streams. Marine, estuarine and lentic habitats are outside the scope of this resource.

Geographically, emphasis is on Central Polish lowland rivers and Carpathian foothill streams, where distinct substrate types and flow regimes influence community composition and require adapted sampling approaches.
