   Active tree planting for rehabilitation purposes is practiced in many areas of the world. In Giant Mts. National Park and Biosphere Reserve, Czech Republic, krummholz (Pinus mugo Turra), shrubs were planted a century ago, over previously cleared areas in the alpine tundra zones. These shrubs were planted in response to damaging flooding events. Recently, this practice has been subject to scrutiny, since the new planations have expanded into the last post-glacial remnants of alpine tundra, threatening continued existence of the original alpine plant communities. Thus, the purpose of this study was to analyze plant communities and soils above and within the zone of planted P. mugo encroachment, and to determine the effects of krummholz shrubs on the underlying soil nutrients (exchangegeable Ca, K, Mg, CEC, available P, and pH). Microclimate in both habitats was also monitored as an additional possible factor driving the ecosystem change.
   Alpine tundra was richer in vascular species while bryophytes and lichens were more prominent in the krummholz zone, suggesting that spreading of P. mugo decreased alpine flower diversity and abundance. Soils in both habitats were of podzolic order. Under the krummholz shrubs, the surface organic layers were significantly thicker, and the A and B mineral horizons were more developed
