Opis:
This paper presents the distribution dynamics, soil and phytocoenotical conditions of the occurrence of Carex pulicaris and Pedicularis sylvatica at the margin of their range in NW Poland. Dynamic cartograms of these species were made on the basis of our field studies and available contemporary and historical records. The studies showed that the plants grow on organic hemic-muck soils, mucky soils and typical muckous soils. The occurrence of these two species on different types of soils proves that they are able to adapt easily to varying habitat conditions of post-bog areas. Populations of C. pulicaris and P. sylvatica were most frequently not numerous and occurred in small community patches. Analyzed phytocoenoses with C. pulicaris have been classified as the community of the alliance Caricion davallianae or the alliance Molinion. Phytocoenoses with P. sylvatica are represented by the association Nardo-Juncetum squarrosi and the community of the class Molinio-Arrhenatheretea. The distribution dynamics of these species shows that they are disappearing from some parts of this region, which proves the recessive trends. This process is more intensive for P. sylvatica, which should be included in the red list of Polish plants like C. pulicaris. The disappearance of the populations of both species has been caused by worsening habitat conditions (insufficient moisture, eutrophication), expansion of competitive plant species and land abandonment.

Opis:
For several years, authors of the present paper have been observing specimens of cypresses of the genus Cupressus planted in Szczecin and its vicinity and within the area of the agglomeration of Gdańsk, Gdynia and Sopot as well as in some botanical gardens and arboreta. The work is a collection of materials from long-term observations and a moderately complete study on cypresses grown in the northern and central part of Poland. In this respect, the present publication fills a gap in dendrological knowledge in our country. The authors have analyzed 6 taxa in total, assessing the possibility of their cultivation in Poland. Also species cultivated in Western Europe and other parts of the world are presented, as a reference to conditions and species grown in Poland. Most species presented in the paper had not been grown in Poland until recently, with the first specimens planted in the 1970-ties. Many of the described species produce flowers and cones and tolerate the Polish climatic conditions well; even temperature drop below –26ºC (winter 2005/2006) did not induce serious injuries and a decrease in their vitality. The species reported in this article as cultivated outdoors in Poland include Cupressus arizonica, Cupressus glabra (most commonly; both represented also by cultivars), Cupressus bakeri, Cupressus semprevirens, Cupressus stephensonii, Cupressus montana. Authors assume that the first three species can be successfully cultivated in Polish climatic conditions especially in places with suitably warm microclimate. The latter ones are represented only by single specimens growing in specific locality (very close to the open sea) so their hardiness have to be further investigated.
