In the modern agricultural landscape major threats to plant species diversity are loss and fragmentation of habitats and communities. During the last century natural and semi-natural communities have faced also cessation of tradition management and increased load of nutrients. This paper presents a survey of studies on vegetation dynamics of woodlands in the northern part of the Carpathian foothills and of calcareous grasslands on limestone hills near Kraków. The causes of fargoing changes observed in communities of these types and possible management for their conservation are discussed. The nature conservation value of woods can be assessed by means of ancient woodland plant species indicators.

The secondary succession pattern observed on an arable field abandoned since 1974 in Tilio-Carpinetum habitat is described and disscussed. Results obtained during 36 years of study confirm that succession on an abandoned field leads from a typical segetal community to the formation of a juvenile treestand composed of pioneer species. Our study supports the view that succession is a process which is largely dependent on the initial conditions and surrounding vegetation. The results indicate that some species can modify the course of this process, accelerating or slowing it down. Limitations of the method and prognosis of future vegetation development are also discussed.
