(2012): Introduced tree species survey and their representation in the park objects of Levice district. – Thaiszia – J. Bot. 22 (2): 201-210. – ISSN 1210-0420. Abstract: The park and non-park objects in 90 settlements of Levice district were searched. Together 70 objects situated in 48 settlements (villages or towns) were found during inventory of woody species in May – September 2011. The results showed that in 90 settlements of Levice district there are situated 70 park and non-park objects. The total number of woody species fluctuated between 4 and 111 pieces, in Čajkov park and Levice city park, respectively. The percentage of introduced, autochthonous, broadleaves and coniferous woody taxa was also determined. In the studied objects there dominated mostly introduced woody taxa and broadleaves..

In terms of shapes, in Slovakia there are not woody species with exactly closed, strictly conical shapes (Thuja sp., Chamaecyparis sp.). Limits are also within colours. Significant red autumn
