The Documentation of Forest Damage Factors 2005 (German abbr. DWF) provides data on important forest pests, diseases, vertebrates and abiotic damages, collected by means of a survey on forest district basis in all privately and publicly owned forests of Austria for the year 2005. Data scertainment is based on the estimation of 68 damage factors. For 20 damage factors the damage was documented as the volume of the damaged wood (in m3), for 42 damage factors as area of the concerning parts of damaged forests stands (in hectare). For the remaining six damage factors only the occurrence was assessed. For the year 2005, the method of the ascertainment has not been changed. Due to the reorganisation of forest districts only slight adaptations had to be made. Therefore, the number of assessment units has decreased by 2, amounting now to 244. In Austria, in addition to the DWF, forest damage data are collected by other surveys, such as Forest Statistics (German abbr. FOSTA) and the Report on Forest Harvesting (German abbr. HEM). From 2003 onwards, DWF has been replacing that part of FOSTA which is dealing with forest damages to avoid misunderstandings when comparing the results of the different surveys and to prevent duplication of ascertainment work. The results for the total Federal Territory of Austria are illustrated by maps of the forest districts allowing a good overview on the forest health situation and acknowledging the trend to the previous year.
