About SimplebrookLine

What This Site Covers

SimplebrookLine focuses on three connected topics within freshwater ecology:

• Stream invertebrates — identifying EPT taxa (Ephemeroptera, Plecoptera, Trichoptera) and understanding their role as bioindicators of water quality.
• Water quality testing methods — the physical, chemical, and biological parameters measured in the field, and how they relate to ecological condition under the EU Water Framework Directive.
• Nature trail walks in Poland — publicly accessible routes through landscape parks and national parks that follow stream and river corridors.

Scope and Geography

The primary geographic focus is Poland, including both mountain headwater streams (Carpathians, Sudetes) and lowland river systems (Barycz Valley, Biebrza, Polesie). General information on invertebrate identification and field methods applies broadly across temperate European stream systems.
