The Documentation of Forest Damage Factors 2003 (German abbr. DWF) provides data on important forest pests, diseases, vertebrates and biotic damages, collected through a survey on forest district basis in all privately and publicly owned forests of Austria for the year 2003. The data ascertainment is based on the estimation of 68 damage factors. In addition to the DWF, in Austria forest damage data are collected by other surveys, such as forest statistics (German abbr. FOSTA) and the report of forest harvesting (German abbr. HEM). To avoid misunderstanding when comparing the results of the different surveys and to prevent duplication of ascertainment work, from 2003 onwards, DWF will replace that part of FOSTA which is dealing with forest damages. As a consequence of the structural changes of the year 2002, Vienna is taking part in the survey since 2003 and the Tyrol has refined the ascertainment by adusting the level of the ascertainment units to those of the other Federal Provinces. Therefore, the number of ascertainment units has increased to 247. As in the year before, the results for the total federal territory are illustrated by maps of the forest districts allowing a good overview on forest health protection.
