The Carici remotae-Fraxinetum association was recorded primarily
at water tricklings or water-head areas of small brooks.
The community is characterized by the dominance of Fraxinus
excelsior in the tree-stand. It also has a significant share of Acer
pseudoplatanus and Alnus glutinosa. Picea abies, Alnus incana
and Quercus robur sporadically occur. In the undergrowth,
numerous species considered as characteristic for the studied
association were noticed, among them were: Carex remota,
Equisetum telmateia, Carex pendula, Carex strigosa, Veronica
montana. Geranium phaeum, Lysimachia nemorum and Petasites
albus achieved high constancy

In 2008– 2009, floristic investigations were carried out in a 48
km2 area located near the towns of Olkusz and Bukowno. The
basic unit (a square of 1 km2 ) was estimated in accordance
with the requirements of ATPOL (Distribution Atlas of Vascular
Plants in Poland). As a result of the study, 730 taxa were
noted. There were 673 species and 40 subspecies. The native
taxa constitute 75,3% of the analyzed flora. Antropophytes
naturalized in Polish flora were 17,2%. Species escaped from
cultivation accounted for ca. 6%. Taxa of uncertain status in
Polish flora made up 1,4%. The greatest and the smallest number
noted in a basic unit were 263 and 37 taxa, respectively.
The differentiation of the flora was correlated with differentiation
of habitats. Localities of 42 taxa which are legally protected
(35 strictly, 7 partly) were noted in the flora of OOR.
In this group the Orchidaceae family was the most numerous
in angiosperms – 10 taxa (6 species and 2 subspecies) while
the Lycopodiaceae family among cryptogamic vascular plants
– 4 species. The concentration of the localities of protected
species was observed in the area with high participation of
seminatural habitats. The research was done as a part of MF
EOG PL0265 project.

The aim of this research was to assess species richness and diversity
of antropophytes in cemetery flora; noting their size,
usage and locality. The field research was conducted in 2007
in the Roztocze region. The investigated area covered 1314km 2
and included 78 cemeteries, all of which were included in our
study. We collected 5004 floristic data which form the basis of
this study. The cemetery flora was rich with 523 species from
75 families.The flora was diverse (mean Marczewski-Steinhaus
index below 40%). The cemetery flora displayed a high level
of naturalness, as 60– 80% of all species were native. The following
species which were most frequently found running wild
in the studied cemeteries were: Amaranthus cruentus, Asparagus
officinalis, Aster novi-belgii, Erigeron annuus, Euphorbia
marginata, Lupinus polyphyllus, Rudbeckia hirta, Saponaria
officinalis and Viola odorata. Results of cluster analysis with
50
Euclidean distances based on such flora characteristics as:
number of species, species cover, share of life forms, share of
geographic-historical and socioecological groups, indicate that
facility usage is the most important factor shaping local flora.
Isolation due to a location in protected areas was ranked second
in importance while facility size was the least important factor.
Medium-sized (5– 10ha) and large (10– 20ha) active cemeteries
were characterized by relatively great similarity as far as the
studied features were concerned.

Beaver lodges are specific zoogenic habitats. The aim of the
study was to check if the flora on lodges differs from its surroundings,
in terms of species diversity and the level of eutrophization
and ruderalization. On 40 investigated lodges, vascular
flora showed a higher species diversity than in the surrounding
vegetation. The number of species was similar, while
the plant coverage on lodges was half that of the surroundings.
The most frequent species were: Urtica dioica, Scutellaria galericulata,
Lycopus europaeus, Lysimachia vulgaris and Solanum
dulcamara. The Lamiaceae, Polygonaceae and Asteraceae
families occurred more frequently on the lodges than in their
surroundings. More species which were resistant to disturbances
(r), hemicryptophytes and therophytes as well as eutrophic
and neutrophic occurred on the lodges. Also the species from
the Alnetea glutinosae, Bidentetea tripartiti and Scheuchzerio-
Caricetea as well as Artemisietea vulgaris and Stellarietea mediae
classes were more frequent on the lodges than in the surroundings.
More euhemerobic and urbanophilous species were
recorded on the lodges. More mezotrophic and acidophilous,
mezohemerobic and urbanophobic, as well as more stress tolerant
(s) species were recorded on the control plots in the vicinity.
Beavers increase number of habitats and diversity of vascular
plants in ecosystems.

The Antarctic terrestrial ecosystems are among the most remote
ones in the world. The striking feature of the Antarctic is
the poverty of vascular plants. Only Deschampsia antarctica
Desv. (Antarctic hairgrass, Poaceae) and Colobanthus quitensis
Bartl. (Antarctic pearlwort, Caryophyllaceae) are considered
successful in this region and have inhabited the maritime Antarctic
(from mild Holocen c. 5000 years). The first appearance
of a new vascular plant Poa annua L. and its establishment on
natural habitats in the Antarctic region were recorded. The species
has been monitored since 1986, only in anthropogenic sites
in the vicinity of Arctowski Station (King George Island, South
Shetlands), but presently it has been also discovered in native
communities on the forefield of Ecology Glacier retreat. The
demographic study shows clearly, that this population has been
stable for a couple of years and represents the new colonist – genus
and species new to the Antarctic flora.
