Research results of the Corydalis solida (L.) Clairv. cenopopulations state in Lviv\'s parks in the different stages of recreation degression of forest communities are presented. On the early stages of recreation pressure (IIľIII) cenopopulation of Corydalis solida (L.) Clairv. are having a low significance of the index of renewal, yield of seeds, high significance of age cenopopulations and coefficient of seeds productivity, predominance generative person in the age structure. In connection with amplification of the stage of recreation degression to ▓VľV▓ increase of the significance of the index of renewal and yield of seeds are observing. But significance of age and coefficient of seeds productivity are decreasing and in age structure pregenerative age group dominate. On the final stages of recreation degression lowering of all parameters under study is happening.

Keywords: cenopopulation, ephemeroides, Corydalis solida (L.) Clairv., recreation pressure.
