The geographical distribution of Piciforms' is one of the factors indicating the state of the forest. These forest birds are bioindicators of climax forest communities. In Šumava National Park, some of the Piciforms' are flag species' and thanks to that, various historical data about them exist. The goal of my study was to evaluate data from 2006-2018 monitoring and add my own monitoring data from years 2019 and 2020. This data consists of location of individual birds living in the region called Smrčina, the southernmost point of the National Park. The goal of this thesis was to determine which factors influence the distribution. The method chosen for the monitoring was so called "point count method", used from the beginning of April till the end of June. For the statistical analysis, the R software was used. And for the visualization of geographical distribution, I used qGis. The result of my thesis is that from 10 Piciform species living in the Czech Republic, 8 live in the studied region. The abundance of Black Woodpecker and Great-Spotted Woodpecker from year 2006 and Three-Toed Woodpecker from year 2009 is stable. (Great- Spotted Woodpecker with 1,6, Black Woodpecker with 0,5 and Three-Toed Woodpecker with 0,8 pairs on one hectare.) The most rare species White-Backed Woodpecker was spotted...
