Documenting Stream Invertebrate Communities

Brook & Craft collects and presents methodological and ecological information on benthic macroinvertebrates in Polish inland waters. Coverage spans field sampling protocols, laboratory sorting and identification procedures, index calculations and reporting formats.

The content draws on publicly available guidance from the Chief Inspectorate for Environmental Protection (GIOŚ), the European Water Framework Directive (WFD) implementation documents, and peer-reviewed literature on Central European stream ecology.

Macroinvertebrates — including stoneflies, mayflies, caddisflies, beetles, chironomids and amphipods — respond to organic pollution, acidification, hydromorphological degradation and other pressures at ecologically relevant timescales, making them a practical and widely used tool for river health evaluation.
