forest district - Opis:
- In the study, regional stand damage risk factors were developed for individual forest districts in Poland. For this purpose we used the materials contained in the database of the State Forests Information System (SILP), which relate to the volume of wood obtained from windfalls and deadwood in all forest districts in Poland in the years 2005−2010. The criterion proposed was the maximum annual damage during the period under review expressed as volume of wood obtained from wind−thrown and wind−broken trees, as well as deadwood per hectare of forest stands older than 40 years in a forest district. This allowed to assign regional damage risk factor values to individual units. They range from 0, corresponding to a very low damage risk to stands, to 4, indicating a very high risk. Presented map of the regional stand damage risk factors for the forest districts in Poland is the graphic result of the analysis.
