The paper presents the productive potential of the State Forests woodland over the years 1991-2005. Changes that occurred in that period were also analysed and explained. The research showed a distinct increase in forest productivity as measured by stand volume, its net increment, and its average increment. There was a favourable change in the species and age structure of timber. Wood harvesting was also on the rise. This upward tendency was possible due to an increase in timber resources in the recent years and to a forest policy seeking to prevent any decrease in the timber quality of the standing crop.

Using GIS techniques, spruce bark beetle Ips typographus (L.) damage was analysed against distance from the edge of small spruce stands with strict protection regime; for reference damage nearby managed spruce stands was used. Mean volume of spruce timber, harvested with sanitary fellings was significantly higher near spruce stands with strict conservation status (14.7 ±2.1 to 17.0 ±3.8 m3/ha) than in the vicinity of managed control sites (9.9 ±0.4 to 11.5 ±0.8 m3/ha). Under endemic spruce bark beetle population levels strict conservation regime in small areas (forest woodland key habitats of average 3.7 ha size) was found to be Ips typographus hazard for adjacent spruce forests up to 450 m distance.

Populations of two species of woodland rodents were studied: Apodemus flavicollis (A. f.) and Clethrionomys glareolus (C. g.)t inhabiting a set of small wood patches, isolated from large, continuous forest. The species composition, density and population dynamics differed from those in the forest. The rodents used the entire area as a patchy habitat, moving between the woodlots. In the breeding season high mobility caused higher mortality among males, especially in C. g. Sex ratio in C. g. was female biased. In A. f. females prevailed in spring whereas there was a prevalence of males in autumn. Seasonal changes in age structure followed different patterns in females and males. Males prevailed in first spring litters in both species. Males also prevailed among numerous immigrants of A. f. but females prevailed among immigrants of C. g. The demographic processes in these species resulted from habitat fragmentation and different life strategies.

In the eastern part of Saxony (Germany), common dormiceMuscardinus avellanarius (Linnaeus, 1758) were found in very small woods (average area of 10 woods was 2.9 ± 1.4 ha) isolated within agricultural fields for more than 100 years (average distance to the next, larger wood 268 ± 84 m). Dormice reproduced even in wood islands smaller than two hectares. Altogether 6 marked dormice were recorded migrating across the open landscape. Of these, 5 were juveniles. Minimum and maximum distances in treeless areas between points of capture and recapture were 250 and 500 m respectively. These migrations over open ground seem to be rare but normal events and explain the presence of common dormice in very small patches of woodland in habitat mosaics.

Counts of roe deer Capreolus capreolus (Linnaeus, 1758) were conducted in the open fields of two reserves in Siena county (central Italy). Area A and area B were characterized by different indices of wood dispersion (0.8 and 1.6 respectively). Solitary roe deer were seen significantly more often in area B (open fields: 80%) than in area A (open fields: 48%). Males were significantly more solitary than females in both areas. Group size varied throughout the year, showing similar tendencies in both sexes and areas. The differences in deer concentration between areas appeared to depend on the distribution pattern of woodland more than proportion of open habitat.

Selection of nest sites by the common dormouse Muscardinus avellanarius L. depends on habitat type and suitable plants that can support and hide dormouse nests properly. Lithuania is situated in the northern part of the distribution rage of M. avellanarius. Some peculiarities of nest site selection in these dormice could be expected here compared to the regions situated further south because of differences in composition of the woody vegetation. Searches for nests of M. avellanarius were carried out in different young woodlands of Lithuania at 16 study sites, and detailed study of nest site selection in this species was carried out in an overgrown clearing in 2005–2006. In comparison to other parts of its distribution range, significant prevalence of Norway spruce as a nest supporting plant was observed in Lithuania. More than 70% of nests of M. avellanarius (n = 120) found in different young woodlands were situated in young spruce trees. In habitats where suitable spruce trees were absent or scarce, young deciduous tress (e.g. oak, ash, aspen, lime, hornbeam) and shrubs (e.g. hazel, bramble, raspberry, willow, honeysuckle) were selected for nesting sites. In overgrown mid-forest clearing, young spruce trees were evidently preferred by M. avellanarius as nest supporting plants despite their comparatively scarcity. Planted oak trees were selected by M. avellanarius for nesting in the plot of the clearing where young spruce trees were almost absent. The average height of dormouse nests was 1.0 ± 0.6 m above ground in young woodlands, and it was related to the age and height of young trees and shrubs.

Plant diaspore dispersal is a fundamental process affecting the development of forest vegetation and its natural regeneration, especially with regard to typical woodland species, which spread slowly and form short-term soil seed banks. Most of these species have poor seed dispersal mechanisms, which is the major cause of their very slow expansion. The following questions were asked: (i) is there a relationship between the age of a woodland and the presence of forest vascular plant species representing different seed dispersal types; (ii) how do the proportions change between species representing different seed dispersal types in relation to the age of woodland; (iii) what factors determine the presence of species representing a given seed dispersal type; (iv) which factors affect the presence and which ones influence the abundance of selected woodland species? A multiple regression models were developed based on data obtained from 144 woodland patches designated for the study. A probit regression analysis was performed for selected species exhibiting various seed dispersal models. Woodland plants of all seed dispersal types show a significant relationship with the age of woodland, starting from the strongest linkage: anemochores, myrmecochores, endozoochores, epizoochores, barochores, autochores. As the woodland ages, the proportion of forest myrmecochores and anemochores grows, whilst the proportion of autochores, epizoochores and endozoochores shrinks. Results obtained indicate that the direct proximity of ancient woodland has a major effect on the occurrence of more poorly dispersing plants in recent woodlands, such as myrmecochores and heavy anemochores.

Moisture along with available calcium content are the major environmental factors controlling species richness and composition of the terrestrial molluscan fauna. In the present study, we focused on snails in a floodplain forest and their response on humidity. We described the model of response and calculate the humidity optima of particular species if possible. Generalised linear model (GLM) combined with Poisson distribution was used to ch aracterise the change of species abundance along a humidity gradient. From 31 species tested, 21 have shown significant response to humidity. The majority of specie s tested had unimodal response, four species showed monotonic regression type. Based on their humidity optima, species distributed along a moisture gradient belonged to three main ecological groups: (i) mesohygrophilous woodland species living mostly in non-inundated areas with humidity optima below 4, (ii) hygrophilous, forest hygrophilous and euryhygric species with optima between 4 and 6 and (iii) strongly hygrophilous (polyhygrophilous) species with mois ture optima above 6. Estimated moisture preferences for Danubian floodplain woodland land snail fauna would be a useful tool in a longterm biological monitoring of changing moisture regime.

One hundred and one stands of non-native red oak Quercus rubra L. were examined across various forest types with the objective to relate the influence of environmental variables on the abundance of this species and to characterise its impact on the species richness and proportion of functional groups of native plant species. Amongst randomly selected stands more than 50% were self-regenerating ones, i.e. seedlings were present. The cover of Q. rubra seedlings was positively correlated with light intensity (rs = 0.38, P <0.05) and negatively with the content of nitrogen (rs = –0.20, P <0.05) and loss on ignition (rs = 0.20, P <0.05) in soil. The cover of mature trees was positively correlated with the value of pH (rs = 0.22, P <0.05). Separate correlations with DCA scores of phytosociological relevés and the cover of red oak in each layer showed that the species influenced the floristic composition of forest vegetation. The cover of mature trees of red oak negatively affected both the number of understorey species (rs = –0.39, P <0.01) and the cover of shrubs (rs = –0.21, P <0.05) and herbaceous species (rs = –0.22, P <0.05). Q. rubra in the form of a mature tree had a negative influence on the cover of barochores, endozoochores and species of Grime’s CSR strategy. The cover of red oak’s seedlings was negatively correlated with the cover of annual species (rs = –0.21, P <0.05). Saplings of Q. rubra had a negative influence on the cover of dyszoochores (rs = –0.21, P <0.05) and was positively correlated with competitors (rs = 0.31, P <0.01), megaphanerophytes (rs = 0.27, P <0.05) and therophytes (rs = 0.25, P <0.05). The study showed that Q. rubra is a competitive species both as a mature tree and in the form of seedlings or small saplings and thus it can contribute to the reduction of biodiversity in forest communities.

The pollen stratigraphical and lithological data obtained from Lake Lasva, southern Estonia, are summarized. The land-use and vegetation history during the last 6300 years in an agricultural area with dense prehistoric setting is discussed. A high sedimentation rate and laminated structure of lake deposits enabled high-resolution palaeobotanical study of a 985 cm long core. Accelerator mass spectrometry ¹⁴C dates show good linearity and fit well with varve counts. Up to ca 2900 years BP, birch, pine, spruce and broad-leaved species, later mostly birch, pine and alder, grew in that area. The first weak signs of human impact were traced at 6300 years BP. Human activities were more pronounced between 5400–5100 and 3800–3500 years ago, due to the foundation of Neolithic settlements not far from the lake. The first attempt of small-scale tillage, detected from the first finds of Triticum pollen, followed by a long-term gap, dates back to 5100 years BP. Crop cultivation (Cannabis, Hordeum, Triticum and Secale) became the main means of subsistence not until the Iron Age at about 1600–1400 years ago, but extensive arable farming started to develop 800 years ago, after the German crusaders invaded the area. Pollen diagrams display several setbacks in arable farming, mostly caused by crop failure due to climate deterioration and decrease in the population caused by famines, wars and epidemics.

Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

Black alder, an N-fixing tree is considered to accelerate the availability of phosphorus in soils due to the increased production of phosphatase enzymes, which are responsible for the P release from the litter. Acid phosphatase activity plays a pivotal role in organic P mineralization in forest soils and in making P available to plants. In order to check whether Alnus glutinosa stimulates acid phosphomonoesterase (PHACID) activity, we compared enzyme activities, total P concentration (PTOT), plant-available P (PAVAIL), organic P (PORG) and inorganic P (PINORG), and organic matter content in 27 ancient and 27 post-agricultural alder woods (the latter ones representing different age classes: 11-20, 21-40 and 41-60 years) of soil samples taken from the litter and the mineral layers. Phosphomonoesterase activity, organic matter, PTOT, PINORG and PORG concentrations were significantly higher in ancient alder woods than in the soils of post-agricultural forests. Significant differences in the acid phosphatase activity, organic matter and PAVAIL concentration were noted between the litter and mineral layers within the same forest type. In recent stands the amount of organic matter and phosphatase activity increased significantly with the age of alder stands, although only in the mineral layer of their soils. Phosphomonoesterase activity, organic matter and PAVAIL content were higher in a litter layer and decreased significantly at a mineral depth of the soil. The acid phosphatase activity was significantly correlated with organic matter content in both ancient and recent stands. There was no significant relationship between PHACID activity and any P forms.
