The quarries in the Bohemian Karst are very impressive even outside the vegetation season. We took advantage of it and selected suitable experimental plots and established an experiment there. In this dramatic environment, Farwa will monitor the establishment success of several sown species in younger and older successional stages. And because there never are too many experiments, we established a similar experiment in a re-grassed field. But most importantly, all plots were localized by our brand new geodetic GPS! The adventure does not end there - next week, we plan to visit active quarries where we (firmly believe) will find young successional stages and establish other experimental plots.
