In this analysis we present the characteristics of the habitats of a species rare in Europe - Botrychium virginianum (L.) Sw., in remote parts of the geographical range on the territories of USA and Russia. The analysis confirms the possibility of the the growth of this species in naturally recovering forests, gives an update of the information about a variety of environmental conditions of growth of this species and shows its similarity in different parts of Europe. At the time of research conducted in Bethlehem this species appeared to be rare, their populations small, which is connected with the cryptic character of the populations of this species as well as with the ability of showing a wide range of polyvariety of ontogenesis. Only in one of the examined populations the age spectre is fully represented and we can see all the basic states of ontogenesis. This species is also rare on the territory of the Kostroma region while the populations are larger and contain all states of ontogenesis of sporophyte. The phenology of the species was examined. The analysis points to the vista of creation of new populations by introduction of spores in new areas and shows the necessity of monitoring in order to develop mechanisms of protection if the species. |
