Permanent complex scientific researches of the whole natural complex as an indivisible unity are conducted at the reserve. A detailed research of biogeocoenoses on permanent sample plots is combined wit overall research of the rest of the area.




Developments inside the biogeocoenoses and local plant and animal communities and their interactions are studied. Permanent observations of changes are practiced; scientists prepare scientific justifications for protection, conservation and restoration of the natural complexes. There are scientific researches conducted to the Ministerial program “Chronicles of Natura”, and also studies in the fields of forest science, botany and phenology.


The inventory of flora and vertebrate fauna of the reserve was held; distribution of plant formations was mapped. There are 45 permanent monitoring plots for tracing primeval forests’ development, 9 phenological stations, 4 zoological and 2 ecological profiles. A register of all  Pinus cembra trees was complied; the oldest and greatest trees of  Fagus sylvatica, Picea abies, Abies alba, Acer pseudoplatanus, Pinus cembra, Betula obscura were registered. An investigation of evolutionary succession through all the stages is held: lichens, mosses and herbaceous plants to green alter, mountain pine shrub communities and further to pine-birch, pine and Swiss pine-spruce which make up a vivid succession which has developed into forest ecosystems.

In order to identify the tendencies within the forest ecosystems a monitoring of vegetation cover is held. Objectives of the first stage are: identification of the flora species composition and identification of rarity species; composing a classification vegetation schemeі; studying the spatial patterns of vegetation layer distribution; research of bioecological characteristics and state of rare plant species’ populations. The  second monitoring stage – phonological researches which target upon identification of a correlation between season rhythms of plants (19 trees and shrubs and 12 herbaceous species), as well as animals and their geographical conditions for living, researches  changes in phonological rhythms in different communities.  At 9 botanic permanent sampling plots the specialists conducts inventories, estimation of season development, measurements of the morphometric parameters and mapping of the following rare species in order to study status of their populations: arnica montane  (Arnica  montana), fragrant orchid  (Gymnadenia conopsea), northern firmoss  (Huperzia selago), perennial honesty (Lunaria  rediviva), East Carpathian rhododendrone (Rhododendron Kotschyi), crocus  (Crocus heuffelianus), spring snowflake (Leucojum  vernum), common snowdrop (Galanthus  nivalis).

A peculiar meaning has an estimation of the primeval forests’ status: an identification of the mortality and new trees appearing dynamics on 29 permanent plots together with succession and development of trees. In order to achieve this experts conduct tree measurements and study the state of populations within the vegetation cover every 5 years, and in every 10 years they identify an intensity of tree increment, state of soils and their physical-chemical characteristics. On zoological trails key vertebrate species are annually observed: lynx (Lynx  lynx), wild cat (Felis sylvestris), brown bear (Ursus arctos), otter (Lutra lutra) and badger (Meles meles).
