Název v původním jazyce

Natural gap dynamics in a Central European mixed beech-spruce-fir old-growth forest

Popis výsledku v původním jazyce

A study on long-term canopy gap dynamics in the Žofin Virgin Forest. The aims were: i) to describe the size distribution of gaps at a given time; ii) to determine the area where dynamical processes occurred within a given period and iii) to determine therole of deciduous versus coniferous trees in gap formation. The fate of individual gaps was followed by analyzing aerial photographs taken in 1971, 1983, 1991 and 2004. The role of individual trees in canopy gap dynamics was studied by combining gap distribution maps with stem position maps of 1975 and 1997 for a 10 ha sample plot. We showed that i) total gap area (9?11%) and average gap size (88?99 m2) was stable during the 33-years study period; ii) canopy dynamics occurred in 0.1% of the area annually; iii) most gaps were created by the simultaneous death of 1-3 canopy trees; iv) death of deciduous trees played more important role in the creation of gaps; v) tree size and neighbourhood also determined if a dead tree became gap maker
