Opis:
Distribution of Loiseleuria procumbens (L.) Desv. in the Eastern Carpathians of Ukraine is presented on the basis of herbaria, literature and the authors' field studies. Site conditions of species occurrence and its phytocoenotic properties are described. The needs' of protection of L. procumbens and its plant communities are discussed.

Opis:
The paper analyses the distribution and occurrence conditions of Loiseleuria procumbens in the Spanish Pyrenees. The species represents a typical arctic-alpine element in the flora of Europe. In the Pyrenees it reaches its southernmost European localities. The Pyrenean populations of the species are not numerous in the majority of the localities. L. procumbens occurs most frequently in the alpine and subalpine zones, at altitudes between 2100 and 2650 m, with a minimum at 1750 m and a maximum at 2900 m. It has been reported nearly exclusively in the siliceous substrata, and predominantly on the north-facing slopes, on the regosols and/or on flat tops of rocks. It forms its own communities, mostly included into the Loiseleurio-Vaccinion alliance, and rarely enters associations of the Festucion airoidis and Rhododendro-Vaccinion alliances. Its typical community, Cetrario-Loiseleurietum procumbentis, is found only in the eastern and central parts of the Spanish Pyrenees.

Pinetum mugo association
Opis:
Pinus mugo occurs only in the highest mountain chains of the Ukrainian East Carpathians. The largest part of the species area covers the Chornokhora ridge and the highest ridges of the Gorgany. In the other mountains of Ukraine it does not form thicket on so large terrains. Vertically, most of localities are placed at an elevation between 1400 and 1900 m, with maximum at 2010 m in the Chornokhora and with minimum about 700–800 m. The latter stands were reported from the peat bogs, however, the most of them have been destroyed and do not exist now. The dwarf mountain pine forms the community of Pinetum mugo, formed exclusively on the substrata not containing calcium dioxide. The species is connected with northern exposures. The area of distribution of Pinus mugo has been strongly reduced during centuries and association Pinetum mugo transformed into pastures.

Opis:
We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.
