The process of forest fragmentation has been observed in many countries, where plant species had adapt to different habitats, such as for example manor parks and rural plantings. A number of scientists have studied the parks as sites where waning environments and landscapes find their shelter. In 2011–2012, research was undertaken on diversity of vegetation in afforestations of parks, rural plantings and oak-hornbeam forests in Sandomierz Basin. In order to compare the means obtained univariate analysis of variance (one-way ANOVA) was used with juxtaposing divided by each of the two criteria: size (the small, and large parks) and conservation(cultivated parks and nonclutivated parks). Tukey’s test was used to examine the significance of differences between respective groups. Analyses were with STATISTICA 9.1. software. Plants classified as forest species, grassland species and those of synanthropic communities were observed in all the afforestations. The parks with high wooded and not mowed areas and oak-hornbeam forests were more forest-like than other types of afforestations studied.
Mostly parks and forest are the most important ‘green islands’ in urban ecological network. Urban forests are belong to green areas and collected many plant species. The main aim of the article was characteristic of ancient plant species in urban forests in Tarnów. The field studies were carried out in years 2011–2012. It covered 80 phytosociological records on the area 500 m2 in herb layer of urban forests and in forest nature on oak-hornbeam. The results showed that many ancient plant species were growing in urban forest but less than in nature reserves.
Celem pracy było określenie zróżnicowania flory wzdłuż wybranych szlaków pieszych zlokalizowanych w zbiorowisku żyznej buczyny karpackiej na terenie Ciężkowicko-Rożnowskiego Parku Krajobrazowego. Badania terenowe i kameralne przeprowadzono w latach 2006–2012. Każdego roku wykonano 700 zdjęć fitosocjologicznych zarówno wzdłuż szlaków turystycznych, jak i wewnątrz zbiorowiska leśnego. Wyniki badań wykazały, iż w obu strefach badawczych dominują gatunki leśne z klasy Querco-Fagetea. Z kolei udział roślin ze zbiorowisk trawiastych z klasy Molinio-Arrhenatheretea oraz synantropijnych z klas Stelarietea mediae i Artemisietea vulgaris był większy wzdłuż szlaków turystycznych niż wewnątrz buczyny karpackiej. Stwierdzono, iż presja turystyczna ma wpływ na kształtowanie się flory wzdłuż wybranych szlaków pieszych.
