Site description The Reka river basin lies between karstic limestone (Snežnik plateau) and fluvial terrain. The river has created a flat plain around the biggest town in the region, Ilirska Bistrica, and industry and dense infrastructure are developing here, although wet grasslands, meadows and small marshes remain. There is extensive farming and orchard cultivation. Land subsidence is occurring where there are abandoned coal mines.

Key Biodiversity An important site for breeding Crex crex. Nationally rare and threatened bird species occur in the site in small numbers. Significant proportion (³1%) of national population breeding at site: Jynx torquilla (10-20 pairs), Picus canus (5-10 pairs).
