In the upper stretches of river Storå, weathering of iron-bearing minerals washed out of the moraine deposits has led to the formation of bog iron ore. The many water courses and small meadowland areas are protected under Nature Conservancy Law § 3 (protected types of nature). The area where river Storå flows into Felsted Kog/Nissum Fjord is a Natura 2000 site and Ramsar area.
The low-lying meadowlands have long provided important grazing areas for horses that form the basis for horse breeding and trading at large farms like Nørre Vosborg. Bog iron ore has been exploited for iron ore and building stones. Possibilities for recreation in the area include angling, canoeing and various activities at the Folkeuniversitet (Open University) at Skærum Mølle.
