Contemporary floristic changes in the Karkonosze Mts.
The paper presents the transformations of species composition in the main plant communities of the Karkonosze Mts. subalpine and alpine belts during the last 35 years. The investigations of floristic changes were performed in associations: Carici (rigidae)-Nardetum, Carici-Festucetum supinae, Crepid...

The paper presents the transformations of species composition in the main plant communities of the Karkonosze Mts. subalpine and alpine belts during the last 35 years. The investigations of floristic changes were performed in associations: Carici (rigidae)-Nardetum, Carici-Festucetum supinae, Crepidi-Calamagrostietum villose and Empetro-Vaccinietum. Signalized are also some vegetation transformations in the remaining belts. The progressing floristic degradation of plant communities in the subalpine and alpine belts consists in: (a) expansion of grasses, (b) decline of rare vascular plants, and (c) elimination of terricolous bryophytes and lichens. In spruce forest belts declining are species connected with old-growth spruce forests like: Listera cordata and Moneses uniflora. The changes of plant communities of low mountain swards (Nardetalia) caused by cessation of pasture and mowing in the cause of retreat of many rare plants, like e.g., Arnica montana.
