Deadwood is an important animal and plant habitat that contributes to the biodiversity of forest ecosystems. According to Slovenia Forest Service data, the volume of standing and fallen trees without stumps and branches in 2010 was 10.11m3/ha, which represented approximately 4% of the entire wood stock of forest stands. In virgin forests, however, the deadwood volume can be even several dozen times larger.
This indicator shows the amount of fallen and standing deadwood. The data is presented for five-year periods from 1990 onwards and for each year after 2005. Annual values are estimates.
Deadwood in forests includes standing dead trees as well as fallen trees, trunks, branches, stumps and roots. The actual volume of stumps and roots is hard to determine, which is why it is mostly not included in the monitoring of forest ecosystems. However, estimates and measurements for these parameters do exist.
The data on deadwood provided by the Slovenia Forest Service includes entire standing and fallen tree trunks not including stumps and branches. For better international comparison, the data from the Global Forest Resources Assessment, which includes all aboveground tree parts, is also presented within the indicator.
