Background. Physical activity is considered to be one of the most important determinants of human health. Many authors emphasize the benefits of physical activity for elderly people – its positive influence on the functioning of many organs and systems, development of greater mobility, slowdown of the involution processes, and counteracting the effects of civilization diseases. Objective. The aim of this study was to analyze the structure of physical activity in older adults from the Lower Silesian region. Material and method. The data was collected as part of the PolSenior national program. The subjects were selected randomly in three stages. The analysis was performed on the data from questionnaires filled out by 192 men and 164 women over the age of 65 years living in the Lower Silesian region. The answers were analyzed in categories such as: age (3 groups: 65-74 years, 75-84 years and over 85 years), gender, place of residence (communities up to 20 000 and over 20 000 inhabitants) and social-occupational status (blue-collar and white-collar workers). The survey results were shown in percentage form and concerned the different types of physical activity performed, the most frequent reasons for undertaking physical activity, sports and recreational physical activity during the respondents youth, between 30 and 60 years of age and at present, as well as the constraints and reasons that prevent an active lifestyle. Results. With age the percentage of people who spend their free time actively decreases. In each age group of elderly people men declared a greater need for physical activity than women. The subjects also differed with the urban factor and socialoccupational status. Moreover, the results showed that the larger community, the better the condition created for recreation of older adults and the people whose previous profession was not connected with physical work tried to be physically active in various forms more often than ex-manual laborers. It is probable that education significantly influences an active attitude towards one’s health and proper lifestyle. Conclusions. Physical activity of seniors as a one of the basic elements of lifestyle is clearly connected with the environment in which older people live.

Natura 2000 sites can be very attractive for leisure and tourism activities. However, these activities can have a negative impact on protected habitats and species. The main aim of this study was to analyze what forms of tourism and recreation have been developed at Lower Silesian Natura 2000 sites, and what are kinds of their impact and what is their intensity. The main research materials are Standard Data Forms. Among the 13 main types of tourism and leisure activities, found in analyzed sites, hiking, cycling, leisure fishing, hunting and their related infrastructure are the most frequently recorded. The results show that low intensities are most often described. The frequency of occurrence of neutral or negative environmental impacts of these activities is the same. However, no examples of positive impact have been recorded.

The material for this study consisted of 60 soil samples collected from the arable layer of cultivated fields located in the vicinity of Wrocław. The samples varied in their properties and reflected a whole range of soil types to be found in the region of Lower Silesia. The examinations proved that selenium content in arable soils near Wroclaw ranged from 81 to 449 μg⋅kg-1 and the average value of Se content in these soils was 202 μg⋅kg-1. The lowest Se content appeared in sandy soils (174 μg⋅kg-1), while the highest value was found in loamy soils. The mean value of Se content calculated for this group of soils was 228 μg⋅kg-1. Selenium content in soils varied to a high degree (V=42%). The value lower than 100 μg⋅kg-1, assumed as a critical one for the quality of plant yield, was recorded for 4 samples, while in 33 soil samples the Se content fell in the range of 101- -200 μg⋅kg-1 and in 14 samples it ranged from 201 to 300 μg⋅kg-1. Only 9 soils out of these subjected to investigation characterized selenium value higher than 300 μg⋅kg-1, i.e. the value regarded as medium soil fertility. Se content in soils was highly correlated with their content of silt and clay, as well as colloidal parts and also with the amount of C and total content of such chemical elements as P, S, Fe, Cu, Zn and Ni.

The paper provides the use of self-organizing feature maps for determination of soil properties in its initial stage of development formed of massive rocks and how SOFM can be used for the study of environmental objects. The study area was Lower Silesia (Poland) overgrown with common, unique and protected vegetation of lichens, bryophytes and vascular plants. The parent rock of the studied soils consists of Miocene volcanites from the middle part of the Sudety Margin Fault. Soil samples were collected from 20 sites. The soil reaction (pH) and concentrations of Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, S, Ti, Zn in surface soils were analyzed. Statistical analysis was carried out by one-way ANOVA. The SOFM was used to demonstrate the non-linear ordination and visualization of soil properties. The SOFM showed the influence of parent rock on soil chemical properties generated by it. SOFM appeared to be effective and proper/fit for phenomena and processes taking place in natural environment and is useful in ecology and ought to be taken into account as a possible tool of estimation of various plants and their biotopes. The model can be useful as alternative techniques in modelling the ecological complex data, and provide a novel framework for the discovery and forecasting of ecosystem structure and behaviours in response to environmental changes.

Rubus guttiferus, known mainly from the Czech Republic, has been found on 25 localities in Lower Silesia (SW Poland). It is as yet a rare bramble there, on the northern border of its range, forming usually very small local populations, and as such should be regarded provisionally as an endangered species in Poland.

Spatial statistics allows to assess geographic distribution of phenomena – its concentration, magnitude and orientation of dispersion as well regularity or trends in occurrence within a space. The paper presents adaptation of point-based methods to measure spatial distribution of areal phenomena that concern agriculture: area of agricultural land, area of fertile agricultural land and soil pH. The source data in a form of chorochromatic maps (e.g. a vector soil map) are processed to 1 x 1 km grid data with use of the algorithm created in Model Builder. The research area – Lower Silesia – characterizes various environmental conditions that results in changeability of agricultural land productivity. Spatial statistics performed for a whole region would bring only global information on spatial distribution. Hence the Authors propose to conduct analysis within subareas that depict local changeability of studied phenomena. As the research is conducted in agricultural context, the subareas of similar agricultural land areas are created regarding the administrative units. Spatial distribution is described by: mean centre, standard distance and standard deviational ellipse. All three measures are weighted by a variable (i.e. the intensity of the phenomenon) as spatial distribution is not only about location, but the value of the phenomenon in particular location is important. Measures of spatial distribution drawn on a map yields clear and usually easy to interpret information on spatial character of a phenomenon. In some cases it may be useful to present these qualitative characteristics complemented with another type of cartographic visualization (e.g. a choropleth map. This paper presents maps about the application of spatial distribution measures into assessment of agricultural land productivity in the research.

Swamp-originating meadows constituting indirect habitats between living peatlands and classical grasslands may be difficult to evaluate. An indiscriminate application of the Oświt (2000) method for their valorization does not fully reflect their value, because of flora which is different from flora found in living peatlands (in particular, the invasion of less hygrophilous flora). Based on the research carried out in the years 2005–2010 on eight swamp-originating meadow complexes, the scale was elaborated which enabled to more accurately valorize these habitat and floristically changed areas. The quantities of valorization values obtained by use of the author’s method rely on the occurrence frequency of a given species (a number of posts in a given area), taking into consideration moisture requirements (the moisture indicator). In the author’s method values were also given for species not taken into account by Oświt (2000). In addition, positive points were given for dying out species, and negative points for invasive species.

Subject and purpose of work: The aim of this article is to analyse changes in quantity and quality of the Lower Silesian Province agriculture labour resources against the background of national tendencies. Materials and methods: The research based on statistics covered the years 1999-2014 including prediction until 2020. The author’s own research carried out on the group of 282 responders in 2013 served the purpose of evaluating the level of farming culture. Results: It was proved, that the number of working-age men in the examined region was increasing much faster than in Poland which led to increase in agricultural labour resources and with that, to hidden unemployment. Lower Silesian farmers are characterized by general and agricultural education of higher degree than Polish average level. Though, it did not translate into entrepreneurship rates. Conclusions: The research proved that the education had a significant impact on the level of farming culture.

This work uses the results of Post-registration Cultivar and Agricultural Experimentation conducted in 1999–2011 in Lower Silesia, on soils of very good and good wheat complex. The rape vegetation season was divided into five periods that approximately corresponded to the phenological phases of the plant, namely: September-November (from sowing to stemming the growing season in the autumn), December-March (stunted vegetation – renewal of vegetation), April (renewal of vegetation – the beginning of flowering), May (flowering), June (end of flowering – technical maturity). In the constructed regression model the following factors were included: the average air temperature and total precipitation in the periods, the content of phosphorus, potassium and pH of soil and fertilization with nitrogen, phosphorus and potassium. Comparing the impact of meteorological conditions in different growing periods of winter rape, it was found that the weakest impact on the yield had temperature and precipitation from September to November. During this period, the optimum for yield are the following conditions: average temperature 10.4°C and precipitation total 145 mm. The winter period (December- March) has the strongest impact on the yield of rape. The yield is conspicuously higher with lower average air temperatures. Optimal for yield is precipitation of 171 mm (highest tested) and a relatively low average air temperature (–0.9°C). In April, the decisive factor is rainfall. Its lower values (12 mm) favour higher yield. The optimum weather in this period is 12 mm precipitation and average temperature of 9.1°C. Rape yield increases with increasing average air temperature in May and is highest when its value is 15°C and rainfall in this month is above average (73 mm). The weather in June has less impact on rape crop than in the three previous periods. The optimal layout is: 27 mm precipitation and temperature 16°C, these values being the smallest tested.

Subject and purpose of work: The aim of the study was to present the development of the tourist function in the areas of Lower Silesian landscape parks. The subject of the study were the communes associated with Lower Silesian landscape parks. Materials and methods: The study covered 59 communes of the Lower Silesia Voiovodeship where 12 landscape parks are located. In this research six indicators of the level of tourism development were listed - three in the field of conditions of tourism development and three in the field of tourist traffic. Results: A significant dependency between the surface area of a landscape park and the state of tourismoriented land development was established. It turned out that among the 59 surveyed communes in 14 of them there are no tourist accommodation facilities. Conclusions: Based on the conducted surveys, it was found that the highest level of tourist function development occurs in the communes associated with the following landscape parks: Śnieżnik, the Sudety Wałbrzyskie, the Owl Mountains, Książ and Bóbr Valley Landscape Park.

In 1998–2001, 2025 trees-of-heaven were recorded in 647 locations in Wrocław, Lower Silesia, Poland. They grew in a variety of habitats. Most were found in lowor high-density residential areas, commercial areas, and in city’s parks. These habitats were moderately to highly transformed and classified as euhemerobic, mainly β-euhemerobic. The mean level of their hemeroby was 61. This is probably an optimum level of hemeroby for tree-of-heaven growing in the urban environment. Because the highest concentration of the locations, where tree-of-heaven grows, was found in densely developed areas of the urban thermal island, it is considered a thermophilic species adapted to urban conditions. Tree-of-heaven spreads largely spontaneously. It is a pioneer species colonising habitats unsuitable for other trees. Therefore, it is recommended for planting in urban areas, especially those situated in western Poland.
