This paper presents the results of floristic studies conducted in the years 2003 – 2005 within the area of the Polesie National Park. The aim of the research was to compare the flora of initial succession stages in drainage ditches with the flora of neighbouring forest areas undergoing transformation as a result of drainage. Floristic lists were made in four designated study areas as well as in forest phytocoenoses. The results of field investigations were subjected to analysis with regard to the systematic affinity of the flora and proportions of plant life-forms as well as of historical-geographical groups and range groups. In the species composition of the studied drainage ditches hemicryptophytes were the dominant group of plant higher life-forms, whereas in the neighbouring communities the flora was represented by both hemicryptophytes and megaphanerophytes. In historical and geographical terms, the flora of drainage ditches and neighbouring communities represents definitely the group of spontaneophytes. Anthropogenic habitats, which developed within the drainage ditches, were colonised by native flora species characteristic for the Polesie National Park area.

Non-productive functions of valuable natural areas

86%
The subject of the study is the presentation of naturally valuable areas in which non-production related functions can be performed apart from the production related ones. The purpose of this article is to address the issue of functions of naturally valuable areas with the focus on their importance for economic and social activity. The present analysis has been based on the specialist research literature as well as on the data obtained from local government bodies. The induction and deduction methods as well as critical literature analysis have been used. The results of the study confirmed that non-production related functions play a significant role in social life and, above all, they can impact the improvement of people’s physical and mental health. They can also provide some valuable raw materials including forest undergrowth while the principles of sustainable growth are followed.

Subject and purpose of work: The research problem is wellness tourism and its connections with forest economy. The main goal is to determine the mutual connections occurring between wellness tourism and forest economy. Materials and methods: The research was carried out in three stages using various methods: a comparative analysis of 39 spas, standardised inspections of facilities offering health tourism services and the selection of a facility being a model of good practice (case study). Results: The most important forms of the small tourist infrastructure offered to patients in forest areas are hiking and bicycle paths (92%), as well as horse trails and viewing points (about 50%). Cluster initiatives and cooperation with local governments and forest districts, consisting in joint promotion, are important. A diagram was developed, showing the interactions of forest economy and wellness tourism. Conclusions: Providers of spa services and State Forests are natural partners, yet the level of cooperation is low and mainly involves promotional activities. It is advisable to create a nationwide forest and sanatorium spa organisation that would coordinate activities in the field of forest economy to take advantage of tourism and health-promoting assets of forests.
The use of habitats by one female moose Alces alces (Linnaeus, 1758) in a managed forest area was studied in 1993-1994. The home range area for the whole year 1993 was 4154 ha (the 90% minimum convex polygon). The area used during January-April in the first winter was 1888 ha (71% of the summer range in May-August). The core area (50% adaptive kernel) was 408 ha (9.8% of home range) in 1993. Forested peatlands were relatively intensively used by the moose. The old and middle-aged forests were used heavily up until the autumn. In the second winter with thicker snow cover the home range was smaller and the use of available habitats more uniform. The characteristics of stands used in the core area did not differ significantly from the average for the whole area. The availability of food was relatively high even in the old-forest habitats due to the forest edges rich in saplings, particularly in the vicinity of peatland. The moose fed mainly on highly available birch and used more Scots pine in the second winter. The availability of palatable saplings, dwarf shrubs and herbaceous plants appear to have seasonal importance in habitat selection. The tops of recently felled trees were utilized for periods lasting for several days. By combining the basic ecological elements, dynamic factors and effects of browsing, the habitat analyses could probably be useful for management planning in moose areas.
In order to clarify the relationship between American martens Martes americana (Turton, 1806), and roads in boreal forests, we tested the effect of distance from road on marten habitat use by comparing the frequency of occurrence, and the number of, marten snow tracks in 27 pairs of 300 and 400 m transect segments perpendicular to access roads, and corresponding segments 800 or 1000 m away from the road, for a total of four spatial analyses. The number of black spruce Picea mariana, stems was generally lower near roads (—94.0 < Ts < —63.0, p < 0.05), but otherwise forest composition generally did not differ significantly between road and forest segments. Depending on the spatial scale, 11-14 road and 15 - 18 forest (out of 27) segments had marten tracks, but the difference was not statistically significant (Fisher's exact test, p > 0.05). In all analyses, marten tracks were significantly fewer near roads (Wilcoxon test: -74.0 < Ts < -62.0, p < 0.01) than away from roads. In segments with tracks, track density was significantly lower near roads than away from roads in three of four spatial analyses (-3.3 < Ts < -2.9, p < 0.01). The findings suggest that snow track samples near roads can detect marten occurrence, but do not reflect the clumping pattern observed away from roads. Habitat selection studies using tracks should consider the possible effect of roads on marten movement patterns.
Traditional agricultural measures are still necessary for maintenance of endangered endogenous species of plants and animals in ecologically valuable habitats. Poland is one of the countries of the highest biodiversity of agricultural lands in Europe, however, the intensification of agriculture and farming resulted with regular decrease of valuable wildlife species. Abandonment of agricultural use of traditionally pastoral areas induced the encroachment of species that reduce local biodiversity. To counteract this undesirable process, several organisations re-introduce Konik polski horses into wastelands. The aim of this overview is to share the experiences of institutions which used Konik polski horses as a mean for biodiversity restoration in post-agricultural and forest areas, including expected effects, their implementation and main problems encountered. The aims, positive and negative effects are presented and discussed.
A set of medium-scale historical maps was used to reconstruct changes in spatial patterns of forest area during the last 220 years in an agricultural matrix of north-eastern Europe (Zemgale region, Latvia). Changes in total forest area by soils were determined, as well as the time period of continuous forest cover. Proportion of protected area for each soil trophic group was also calculated. Patterns of recent forest development differed between soil trophic groups. Afforestation occurred mainly on wet and poor soils in the 19th and 20th centuries, while the proportion of woodland area on fertile soils typical for nemoral forests was fairly stable. Only 1% of the fertile soil area has been covered by continuous forest for more than 220 years, and only 11% of them are protected. Nemoral deciduous forests cover only 15% of their potential natural vegetation area of forested eutrophic soils. Therefore, in regard to habitat protection that is representative of natural distribution of ecosystems, priority in conservation should be given to forests on fertile soils.
The aim of the study was to analyze the total content of micronutrients in the soils in some habitats in the area of the Jezierzyca River Valley Landscape Park. Experimental sites were chosen with regard to different habitats (humid mixed coniferous forest, fresh mixed coniferous forest, humid mixed forest, fresh mixed forest). There are arenosoils, rusty and podzol soils and gley soils. The soils were developed from the river alluvial sands and fluvial sands and prove the acidic reaction. Results showed that the total content of Mn, Zn and Cu is highest in the organic levels and decreases with the depth in the analyzed soils. Only in the podzols soils the total content of Mn decreases in the eluvial horizon and increases in the iluvial horizon. The conducted investigations indicate no pollution of the soils with the micronutrients. The exception was a higher content of Cu in the superficial level of soils in humid and fresh mixed coniferous forest.
The study shows a high dynamics approximately five-year-old natural regeneration of silver birch (Betula pendula Roth) growing on the research plot located in the fertile mountain habitat in the middle of the lower montane forest zone in the Silesian Beskid Mountains (Beskid Śląski) compared to its co-occurring species. The dynamics is expressed as a significant annual increment in height and diameter of birch trees, leading in consequence to the appearance of an older sapling phase for most regenerations of this species. This creates the possibility of early undercanopy planting of tree species adjusted to the site conditions, mainly silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.).
In recent years, brown bear Ursus arctos populations in Iran have experienced a clear trend of reduction and the species is now officially listed as threatened under provincial legislation. Anthropogenic habitat alteration and increasing human access to previously remote landscapes are potential source of stress for this species in Iran. Therefore, land cover changes in the Chelcheli protected area were mapped for 1991–2013 using time sequential Landsat TM and ETM at 30 meters resolution. Moreover, Maximum entropy (MaxEnt) modeling was used to investigate habitat selection of brown bear. The results showed that suitable patches overlapped with forest areas (Hyrcanian forest) and rivers. Our results also indicate that the brown bear habitat suitability is negatively influenced by human disturbance (e.g., roads, settlements). Increased human disturbance in brown bear habitat in recent decades may cause bears to avoid the disturbed areas. Therefore, the management plans should focus on reducing the human infrastructures around brown bear habitat. A suggestion is to place the core secure areas for brown bear inside the suitable habitat close to rivers where the human access is restricted. Promoting awareness of biodiversity conservation among tourism should also be one of the major focuses of management plans.
