After a long break which proved visionary foresight of Josef John, prof. RNDr. Ing. Alois Zlatník, an important figure at the Faculty of Forestry at former University of Agriculture in Brno, began very detailed and extensive research in the area of Eastern Carpathians (former Czechoslovakia, present Ukraine).
Pop Ivan 1935 – sample plot No. 13, permanent square No. 24
From 1932 to 34, he carried out pedological, phytosociological and dendrometric survey at three localities (Stužica, Javorník, Pop Ivan). He placed so called sample plots of various sizes (3-8 ha) into each locality. These sample plots held a number of detailed surveys (detailed research of herb layer on fixed squares, etc.). The results were summarized and published (ZLATNÍK 1935, 1938).
Pop Ivan 1935 – sample plot No. 11 – vegetation map
After 60 year (between 1996 and 1998) a research team from the Institute of Forest Botany, Dendology and Typology of Faculty of Forestry and Wood Technology, Mendel University of Agriculture and Forestry in Brno, managed to find original borders of some sample plots in the Pop Ivan locality (sample plot No. 11) and Javorník locality (sample plots No. 6 and 7) and repeat a complex survey on them. Since 1997 the research work has been carried out in collaboration with the Department of Forest Ecology, Nature Conservation Agency (present VÚKOZ). In the period 2002-2005 sample plots No. 5, 12, 13, and 14 were identified and repeated surveys were carried out on them.
