The impact of spruce plantations on burozem in the Kaliningrad region

Abstract

Monodominant 30-50 year old fir plantations develop a specific forest floor and are characterised by general humus accumulation, the qualitative composition of which is, however, subject to degradation, which is revealed in increasing migration ability and the impoverishment in nitrogen. Semi-hydromorphic gleysols show the initial signs of podzolization.

The new locations of rare vascular plant species in the conservation areas of the “Vepsian forest” nature park and their immediate vicinity (the Tikhvin district of the Leningrad region)

Abstract

This article offer information about the locations of rare vascular plant species in the eastern part of the Leningrad region (the Tikhvin district) on the territory of the "Aschozersky", Urya-Kanzhaya", and "Carboniferous Outliers" conservation areas of the "Vepsian Forest" nature park and their immediate vicinity. Isoëtes echinospora and Lobelia dortmanna appear in the Red List of the Russian Federation. These species, as well as Viola selkirkii are included in the Red List of the Leningrad Region. Poa remota, Hammarbya paludosa, Caltha radicans, Polemonium caeruleum are new to the Tikhvin District.

The lichens of state protected country estate parks in the Pskov region

Abstract

This article presents the first attempt to study lichens in 6 state protected parks in memorial country estates of the Pskov region. The authors distinguished 111 lichen species, among which 7 were proved to be rare and 4 – new to the Pskov region, and performed taxonomic analysis and the analysis of lichen life forms. Special attention was paid to the epyphite group predominant in the parks.

The traces of Holocene events in the spore and pollen spectra of peat deposits in the southern part of the Kaliningrad Region

Abstract

New data on the palaeoenvironment (vegetation and climate) in the southern part of the Kaliningrad Region were obtained through the processing of peat samples from Podlipovo peatland by means of pollen analysis. The results of the study indicate the prevalence of pine and birch forests in the early Holocene; the gradual introduction of broadleaved species occurred in the middle Holocene (the Atlantic). Fagus and Carpinus expansion in the sub-Boreal and sub-Atlantic affected the species composition of broadleaved forests; this period also saw the proliferation of broadleaved-coniferous forests. Pollen diagram was divided into 8 local pollen assemblage zones (LPAZ). The development of the bog was traced by means of peat macroremnants analysis.

The epiphytic lichens growing on roadside deciduous trees in the north-west of the Kaliningrad region

Abstract

This article presents the first attempt to study the fruticose and foliose lichens of the pre-war plantings alongside minor roads in the Slavsk district of the Kaliningrad region. It is the first study of the deciduous roadside plantings in this area. The authors determined predominant species, analysed the wood species composition and came to the conclusion that the predominant ones were the species of the ash and tilia genera, while the number of lichen species was estimated at 29.

The botanic garden of the Immanuel Kant State University of Russia as a centre of environmental education in the Kaliningrad region

Abstract

This article considers the problem of biodiversity preservation and environmental education on the premises of the Botanic garden of the Immanuel Kant State University of Russia. The authors argue that the Botanic garden has favourable opportunities for promoting environmental culture and spreading environmental awareness in different groups of population. An education programme was developed and empirically grounded; effective means, forms and methods of raising environmental awareness and promoting environmental culture in preschool and primary school students were determined alongside the determination of the peculiarities of
organisation of training and conservation measures in the Botanic garden.
