Summer is in its peak and you can hardly find a better place where to go than Carlsbad. It sounds tempting! This is exactly the place where kaolin mining sites are located - mining sites for which we have not compiled a succession sere of vegetation development yet. We managed to sample the vast majority of localities and enjoyed the beautiful scenery. Next year, we are going to visit very old mining sites, which are no longer visible on the maps. Thanks to the perfect knowledge of the history of mining provided by our local guide, we also have the exact age of the sites - what more could a restoration ecologist wish!
