Bulygin, Nikolai Evgenievich

Born on August 12, 1924 in the city of Voronezh . In 1953 he graduated from the faculty of landscaping of cities and towns at the Forestry Academy . He joined the academy, in which he worked until the end of his life. For many years Bulygin served as director of the LTA Botanical Garden. Since 1954 he taught dendrology at the Department of Botany and Dendrology, first as an assistant, and then as a professor and head of the department. In 1965 he defended his thesis under the leadership of S. Ya. Sokolov .

N. E. Bulygin made a significant contribution to the organization of the scientific work of the Department of Botany and Dendrology, to the improvement of the educational process. He has written many textbooks on dendrology, botany, phenology, botanical resource studies, biology. In 1985, his textbook “Dendrology” was published, reprinted in 1991, which is still the main textbook recommended for students of forest universities. During his life he has published 20 monographs and reference books, in total about 160 scientific publications.

For 50 years, Nikolai Evgenievich conducted in-depth phenological observations. Many of Bulygin's works are devoted to the biology of the growth, flowering, and fruiting of introducers in the climatic conditions of St. Petersburg. Bulygin developed a calendar of nature of the North-West of Russia, strictly argued biologically, geographically and mathematically. Such a calendar allows predicting their subsequent passage based on previous phenophases. He identified 4 seasons of the year, 13 sub-seasons and 22 pheno-stages. In the 1980s, Nikolai Evgenievich began to develop the principles of indication and proposed an original system of detailed fenoindication of the structure of the annual cycle of landscape development. Bulygin's fenoindication system has not lost its relevance today.

Back in the 1970s, N. E. Bulygin began to write about climate warming and its effect on woody plants . His work confirms that the winter hardiness of wood introducers , which were previously considered unsuitable for cultivation in Leningrad, has increased. To assess the frost resistance of plants, as well as assess the state of plants, Bulygin revised and significantly expanded the scale for determining frost resistance and plant condition, proposed in 1917 by E. L. Wolf . The scale of N.E. Bulygin is still used. About 150 species of introducers recommended them in the landscaping of St. Petersburg. Under his leadership, a significant amount of introduced woody plants were tested in the LTA Botanical Garden (about 200).

In 1997, Bulygin was elected to the post of professor at the Department of Botany and Dendrology. Nikolai Evgenievich was the chairman of the Central Phenological Commission of the Russian Geographical Society . In 2001, he was officially registered in the federal register of experts in the scientific and technical sphere.

N.E. Bulygin died on May 22, 2002. He was buried at the Kuzmolovsky cemetery in the Leningrad region.
