Lactarius omphaliformis is a species associated with alder, and growing in some of the most vulnerable and declining habitats – wet woodlands. These habitats are among the most threatened type of terrestrial habitats due to hydrological system modifications, agriculture, surface water and air pollution (eutrophication), natural succession, and erosion and forest management. Thus, the species are threatened by habitat loss and degradation. The current locations are in an ongoing procedure for being declared Natura 2000 sites. Despite the fact that Monospitovo Swam has been under protection since 1985, its area decreases continuously, and of late its usurpation and degradation has intensified.
