✦ Synopsis


The studies were conducted in the Biatowie~a primeval forest on a study area of 28,000 m 2, divided into two plots and 280 quadrats. In 1979, all Carpinus betulus individuals were cut offwithin the experimental plot (E, 7800 m2), whilst the control plot (C, 13000 m 2) remained unchanged. Each plot contained a phytocoenose of Potentillo albae-Quercetum and an adjacent community of Tilio-Carpinetum.

By 1983, hornbeam invasion into the oak-forest habitat within C plot had resulted in: 1) a decrease in species number by more than 10 per 100 m 2 on average (c.a. 30%); 2) a twofold greater deletion rate of heliophil oak-forest species than for Fagetalia and Querco-Fagetea; 3)a diminution of the area of oak-forest phytocoenose by more than 100 m 2 per year; 4) formation of a community with a species combination corresponding to Tilio-Carpinetum. Hornbeam removal had the opposite effect: 1)the number of species increased by more than 100% ; 2) the number and frequency of oak forest species rose considerably; 3)those parts of the phytocoenose colonized previously by Carpinus betulus regenerated, and thence the area of Potentillo albae-Quercetum community increased.
