Secondary forest succession in abandoned glades of the Pieniny National Park

Bodziarczyk J., Michalcewicz J., Szwagrzyk J.

Polish Journal of Ecology

1999

Vol. 47, no 2

175-189

The research was conducted in two abandoned glades in the Pieniny National Park (Western Carpathians), were mapping and measurements of invading trees and shrubs had been made in July 1988. Based on re-measurements carried out in 1995, the role of different woody species in secondary forest succession was evaluated. During seven years between consecutive censuses process of succession in both glades displayed substantial convergence. Sycamore Acer pseudoplatanus L. was the main species invading meadows, followed by the hazel Corylus avellana L. Silver fir Abies alba Mill. was common among seedlings, but less numerous among larger saplings. Both sycamore and silver fir seem to be able to invade dense herbaceous vegetation, but higher growth rates allow sycamore to dominate in the early stage of secondary succession.
