The moving dunes in Slowinski Park 

The plant life in Slowinski Park currently consists of: 911 species of vascular plants and 165 species of bryophytes There were also about 300 species of algae, 424 species of mushrooms and fungi, and 225 species of lichens found.

The favourable maritime climate in this part of Poland, with relatively cool summer and mild winter, creates supportive conditions for plants of the western (Atlantic) type of range.

These include, among others: aquatic plants, peat land plants, dune plants, and shrub as well as forest plants. 

Also plants of the north-eastern (Boreal) type of range constitute a distinctive group.

These plants arrived to Pomerania during the end of the last glacial period and they were a component of tundra. Today they are considered to be glacial relics. There are few thermophilic species, those of the southern type of range.
