Th e three zonal complexes of clavarioid fungi at the south-eastern part of West Siberia (Novosibirsk region and Altai
Krai) were investigated. Th e steppe mycocomplex is the poorest, includes 27 species, forest-steppe richer half (56 species).
Only one species is specifi c for both of them. In contrast, the hemiboreal mycocomplex of the Salair Ridge is
considerably richer, unites 100 species, 44 of them found only here. Comparison of the taxonomic structure at investigated
mycomplexes with those of the Eastern European, Urals and East Siberian help for creating of mycogeographical
lines which are separating the West Siberian plain from the mountaine range, the Urals and Salair.
Species composition of the obligate fraction of psammophytic fl ora of Siberia and adjacent areas was identifi ed by the
results of fi eld study and literature data. Centers of its diversity in Siberia were singled out. Links with adjacent
regions were analyzed with the help of inclusion measures, which allowed to assess originality of the psammophytic
element of fl oras for Siberian regions. Baikal Siberia may be considered as an independent center of psammophytic
diversity of North Asia.
Th is article describes new plant association of small-leaved forests with well-developed herbaceous layer from western
part of Kuznetskaya depression. Ecology, genesis and geographical distribution of association communities are
shortly described.
Classifi cation of watershed meadow communities of Arrhenatheretalia order occurring on Tobol-Irtish and Ob-
Irtish watersheds (subtaiga subzone) was made according to the Braun-Blanquet approach. 3 associations and 4
subassociations of alliance Festucion pratensis were described. In this area meadow communities on abandoned
arable lands predominate. Meadow communities on zonal soils belong to the association Cirsio setosi-Phleetum
pratensis. It is represented with 3 subassociations. In the western part of studied area (Tobol-Irtish watershed) on
sandy weakly-acidic soils meadow communities of Loto corniculati-Agrostietum tenuis dianthetosum deltoidis
subassociation with Agrostis tenuis as dominate are common. Th e meadows of Aegopodio podagrariae-Phleetum
pratensis association occur in the eastern part of studied area (Vasyugan plane of Ob-Irtish watershed). Th ey are
situated in small depressions and at forest edges. Under anthropogenic pressure (haying) they replace forest meadow
(Geranio bifolii-Brachypodietum pinnati) association.
Th e description of the association Carici aquatilis-Juncetum brachyspathi Taran et Tyurin ass. nov. (Phragmito-
Magnocaricetea Klika in Klika et Novak 1941, Magnocaricetalia Pignatti 1953, Magnocaricion elatae W. Koch 1926)
is given. Th is association occurs in mouth sors of the Ob River tributaries within the limits of the middle taiga
subzone.
Th e characteristic of suburban communities containing brakes in the grass stand is given. Transformation of their
species composition under anthropogenic infl uence and response of brakes to diff erent degrees of load are shown.

Mooseberry (Viburnum edule (Michx.) Rafi n.) is cultivated at Botanic garden of the Komarov Botanical Institute RAS
(Saint-Petersburg) since 1999, it is winterhardy and produces fruits. Th is threatened arboreal species is recommended
to be included into the forthcoming edition of the Red Data Book of Russia as vulnerable species. Taking in mind
its value and promising qualities for gardening and horticulture it is recommended into wider cultivation which will
promote its ex situ conservation.
Intensive use of the rare species Hedysarum theinum habitats in the Altai Republic for cutting, overharvesting of red
root for medicinal raw material and slow rate renewal may lead this species to extinction. Creation of artifi cial
populations of this voluable plant will help obtaining raw material for medicinal preparations, as well as reintroduction
of the plant to natural localities.

Keywords: introduction, levels of adaptation, threatened species, woody fl ora of Russia
Th e gardener of Imperial Forest Institute Egbert Wolf (1917) tested the largest amount of woody species at Saint-
Petersburg, with 46 species which now are included into the Red Data Book of Russian Federation. Till recently the
main ideas on winterhardiness of woody exotic plants have been based on Wolf s data. In conditions of the warming
of the climate which has strenthened since the end of the 1980s, the amount of non-hardy species has diminished, at
the the same time the amount of hardy species has enlarged. Th ere are more species which reach its reproductive
state, and 4 of them produce the self-sowing.
