Effects of Disturbance on Understory Vegetation across Slovenian Forest Ecosystems

“…Observed changes in forest vegetation were clearly driven by various disturbance events, spanning from local tree-or ground-layer disturbances, more or less limited to the investigated plot area, as well as more widespread disturbances (e.g., gradual canopy mortality) inducing profound alterations to stand canopy structure in the surroundings of our study sites. A distinct change in the network of IM sites across Slovenia was the transition from homogenous, closed canopy stands to more open stands due to a variety of local and widespread disturbance events that occurred during the past decade, including windthrow, snow-break, ice-storm damage, pathogens, bark-beetle outbreaks, and salvage logging activities that routinely follow natural disturbances [39,[45][46][47][48]57]. Apart from quantified natural and anthropogenic disturbance effects, a variety of other processes could be directly or indirectly driving these diversity changes at different scales.…”

“…A longer monitoring period would be required to capture the understory response to these recent disturbances. Widespread severe bark-beetle disturbances and salvage logging followed the 2014 ice storm event [46][47][48]57], further opening the canopies at some of the IM sites, which is likely to lead to more pronounced changes to the understory in the future. Forest plant communities respond to changes of ecological conditions with some time lag.…”
