Investigations concerned the effect of different environmental variables on health condition of English oak (Quercus robur L.). It was shown that in the public parks in the city of Poznan the health condition of the analysed species is good. It was stated that health condition of this species in the Poznan parks is influenced by the distance from the immediate city centre, vicinity of traffic arteries and gas emissions from the combustion of fossil fuels by households neighbouring with the parks. Although results recorded in this study confirm literature data concerning the effect of environmental variables on health condition of English oak (Quercus robur L.), it was shown that certain environmental variables have a greater effect on health condition of the analysed species in Poznan.
Ornithological tourism, also known as birdwatching, is a form of cognitive tourism. Poland has enormous natural potential and ornithological tourism is developing more and more dynamically, so it is important to understand and organise it well. The aim of this study is to review information about ornithological tourism as one of the branches of tourism. It is also to prove that birdwatching may be the basis for tourism and economic development both in its local and regional aspects. The article also attempts to indicate the needs of tourist infrastructure for the development of ornithological tourism on the basis of a survey of 356 respondents, including 87 women. Most of the respondents were young people, aged under 35 (66,4%). 78% of them were urban inhabitants. Most had higher (64,4%) or secondary education (27,8%). The respondents indicated Biebrza National Park (18,3%), Warta River Mouth National Park (16,5%), the Gulf of Gdańsk (8,7%), Milicz Ponds (7,2%), Lake Jeziorsko (7,1%) as the most popular places of ornithological tourism. 34% of the respondents were of the opinion that birdwatching sites in Poland were poorly prepared for the activity.
Parks in urbanised areas fulfil an important function as they create a positive climate in cities and contribute to the good health of their inhabitants. The study gives an answer to the question of which of the species under investigation is the most suitable for planting in urbanised areas. The aim of the research conducted from 2013 to 2014 at selected sites in Poznan (Poland) was to determine the state of health of Tilia cordata Mill., Acer platanoides L. and Quercus robur L. trees and to compare their state of health depending on the location of the research sites. The aim of the research was also to determine the environmental variables that may have an influence on the state of health of the tree species under analysis. The research included statistical analyses and models based on discriminant analysis. The research revealed that the state of health of the tree species under investigation growing in the city is determined by anthropogenic factors. The closeness of the city centre, main thoroughfares and estates heated with fossil fuels are the factors that have the most negative influence on the state of health of oak, maple and lime trees. Acer platanoides L. was the species in the best state of health in parks, whereas in forests it was Tilia cordata Mill.Ke y wor d s: Norway maple, pedunculate oak, small-leaved lime, statistical models, urbanised areas
Streszczenie. Praca dotyczy parku zabytkowego, będącego częścią założenia rezydencjonalno--folwarcznego w Konarzewie. Opisywany obiekt ma długą i bogatą historię, jest niezwykle cenny pod względem architektonicznym, krajobrazowym i historycznym. Wieś Konarzewo stanowiła własność znanych rodów szlacheckich: Konarzewskich, Radomickich, Działyńskich, Dzieduszyckich czy Czartoryskich (ich własnością pozostawała do 1945 r.), obecnie ponownie stanowi prywatną własność. W ramach prowadzonych badań park został objęty szczegółową inwentaryzacją i koncepcją rewaloryzacji.Słowa kluczowe: rewaloryzacja zabytkowego parku, analiza dendrochronologiczna, park krajobrazowy
WstępZałożenie rezydencjonalno-folwarczne w Konarzewie ma bogatą historię oraz jest ważnym i cennym obiektem pod względem architektonicznym, krajobrazowym i historycznym. Konarzewo było wsią szlachecką i stanowiło siedzibę znanych wielkopolskich rodów. Po 1945 roku, podobnie jak wiele innych zespołów tego rodzaju, zostało wraz z terenami uprawnymi, należącymi wówczas do rodziny Czartoryskich, upaństwowione. Do 1992 roku zespołem zarządzało Państwowe Gospodarstwo Rolne. Spowodowało to przerwanie historycznej ciągłości funkcjonowania obiektu. Błędne decyzje dotyczące zagospodarowania założenia, brak świadomości o jego wartości historycznej i struktu-
