Out of all the people who visit Polish forests, not even one would fail to no-tice the trash, so often hidden here and there between the trees. Nature 2000 area is not free of it either. Is is essential to define how much and what kind of litter is in these forests. Operations where carried on in 2010 on the grounds of the Ostrów Mazowiecka community forests in order to determine the trash location and its amount. Data gathered thanks to the GPS techniques where inserted into the GIS system. This greatly helped in carrying out spatial analysis of the phenomenon under investigation.
