“…Lesní potok is one of 14 catchments in the Czech GEOMON network (Oulehle et al, 2021) and thus has been part of several cross-site comparisons (Bohdalkova et al, 2014;Fottov a & Skorepov a, 1998;Nov ak et al, 2005Nov ak et al, , 2010Oulehle et al, 2008Oulehle et al, , 2017Oulehle et al, , 2021. The catchment is well-characterized in terms of its physical properties (soils, geology, vegetation, hydrology;Janoušek et al, 2014;Navr atil et al, 2003). Lesní potok was the site of studies on beryllium cycling (Navr atil et al, 2002;Skrivan et al, 1993), lead geochemistry (Navr atil et al, 2004), manganese cycling (Navr atil et al, 2007), rare earth elements in vegetation (Špičkov a et al, 2010) and Hg in soils (Navr atil et al, 2014) and stream water (Navr atil et al, 2015).…”
