ABSTRACT
Data on share of grasses in the flora of selected 65 gravel-pits of the Siedlecka Upland as well as their ecological characterisation are presented in the paper. The Poaceae is one of the most species-rich families found in these localities. Among 60 grass species the most frequent include Arrhenatherum elatius, Dactylis glomerata subsp. glomerata and Elymus repens. The domination of meadow species from classes Molinio-Arrhenatheretea and Trifolio fragiferae-Agrostietalia stoloniferae as well as synanthropic grasses from classes Stellarietea mediae and Agropyretea intermedio-repentis was observed. The dominant life form of grasses are hemicryptophytes. Native species prevail over anthropophytes in the studied objects. This paper also presents the results of analysis of the flora based on ecological indicator values [21].
Key words: Poaceae, gravel-pits, ecological indicator values, Siedlecka Upland.
