1105 species of high vascular plants grow in the Park. They form 94 families and 420 different varieties. Most frequently you can see different species of sedge, hawkweed, meadow fescue and annual meadow grass.
80 species of flora have been entered into the Red Data Book of Ukraine and 4 species – to the European Red List, 3 species – to the IUCN Red List, 2 – to Bern Convention. About 60 relict species grow in the Park.
Due to the change of climate and soil conditions caused by altitude differences, the vegetation changes as well.
Beech forests zone is situated in the foothill and mountainous areas of the Park. Native forest types such as the European beech have been accompanied by sycamore, Scots elm and Norway maple.
Due to lower temperatures, a zone of mixed coniferous-leaf forests has been formed. It is represented by the forests with fir and beech.
The largest area in the Ukrainian Carpathians is a large mass of mixed and pure spruce forests that have been conserved by the Park. They grow in the altitude from 1100 to 1600 m a. s. l.. The Swiss pine grows in the massif connecting the Kedrovaty of Chornohora range, on the south stony slope, on the altitude of 1470 m.
Sub-alpine zone is situated higher than the spruce forests. This zone is represented by curved woodlands with creeping pine, Duschekia viridis, common juniper and sub-alpine meadows. Rare groups of rhododendron can be found here.
Alpine zone is situated at the altitude from 1850 to 2061 m a.s.l. only in highlands of Chornohora massif.
Forests are the biggest treasure of the Park. There are three forest-forming species: spruce – 79%, fir – 4% and beech – 10%. Pine, cembra pine, horn beam, alder and others can be also found. The virgin forests age range is from 170 to 220 years and is of great value to the region. Relict stands of pine and cembra pine are in Zhenetsky, Tatarivsky and Bystretsky areas of the Park that are unique nature objects. Spruce virgin forests are concentrated at Hoverla and Vysokohirne areas, fir and beech virgin forests are mostly found at Pidlisna, beech virgin forests are found in Yamna and Yaremche areas. Virgin forests are preserved due to their inaccessibility in forest and have been conserved since early 20 century.
Now, virgin and natural forests including relict stands cover an area of 1.3 thousand ha or 4% of the total forest area. Virgin forests are the most productive and firm stands of the Park. As an integral part of wilderness, they have high landscape and aesthetic value.
Creating high productive forest plantations and biological persistent forest plantations according to the determined conditions and type of the forest is the main goal of recovering the forest. The selective point called "Pidlisniv" was created to put those tasks into practice.
