The collection takes place in five selected areas to cover the entire length of the river. It was the region og the spring, the Morávka, Pražmo, Skalice and Frýdek-Místek districts.

An important discovery is the finding of one very rare species - Pardosa agricola, two rare species - Arctosa maculata and Pardosa morosa.
