The main aim of the research is to identify landscape fragmentation (LF) in Slovakia with special emphasis on the contribution of protected areas (PAs) to mitigate the effect of LF. Results are presented in the final raster output (10 m grid). The raster contains 490,321,151 individual 10 m raster grids, with the LF average value of 59.12 % (where 0 represents fragmented landscape, 100 represents fully connected landscape by natural or semi-natural ecosystems) on the national level For each category of PA, individual statistics of quality and quantity of LF are estimated and subsequently compared with unprotected parts of Slovakia. The comparison of all PAs with each other resulted in 1,132 unique assessments. The overall average value of LF of unprotected parts is still rather high (56.42 %) and it shows that there are still significant areas existing, which are situated in unprotected parts of the country.
