Forest protection research in the Far East began in 1939 with the establishment of the forest protection sector under the leadership of L.V. Lyubarsky, who can rightfully be considered the creator of regional forest phytopathology. His unique collection of mushrooms includes more than 300 species, among which 16 are new to science. New species of bark beetles are described.

Research has been conducted in this area on a number of issues.:

- the study of pests of cones and seeds and their economic importance, while two new species have been discovered for science, a long-term diapause of pests of larch and spruce seeds has been revealed;

- studies of the Siberian silkworm, including the duration of generation, frequency of mass reproduction, and natural mortality factors have made it possible to adapt the pheromone monitoring method.;

- study of diseases of seedlings and development of protective measures for nurseries. Protective measures and a set of chemicals are proposed.;

- study of regional features of biology and population dynamics of the unpaired, pink unpaired silkworms, hazel peacock-eyes and other lepidoptera. Methods of accounting for the number and forecasting of mass breeding have been developed, and monitoring methods have been introduced.;

- the role of Jacobson's moth, a complex of spruce and fir leafworms, and bark beetle foci in the drying of spruce forests has been revealed;

- study of the dynamics of the number of mouse-like rodents and their importance for forest production. Recommendations have been developed for the protection of nurseries and forest crops in the Far East from mouse-like rodents and birds with a number of original mechanisms and chemical methods for regulating the number of rodents and scaring birds.

Based on the materials of the conducted research in the forest pathology field, numerous scientific articles, monographs, and recommendations to forestry production have been published. The staff of the Institute and forest experimental stations defended 3 doctoral and 9 candidate theses.

Comprehensive forestry research in the Far East began in 1949. In 1955, an independent laboratory for the Protection of forests from fires was organized under the leadership of A.M. Starodumov.

Over the years, the research topics included: the study of the thermophysical properties of forest fuels, pyrological characteristics of forests, patterns of occurrence and spread of fires, physical and mathematical modeling of forest fires. This made it possible to develop a genetic classification of forest combustible materials, recommendations for fire prevention and extinguishing, and fire hazard scales for regulating the work of forest fire services.

Much attention was paid to the problem of large forest fires, their evolution and influence on atmospheric processes were studied. For the first time, a new type of forest fire "turf" was isolated and described. Significant material has been collected on the environmental consequences of forest fires and the post-fire dynamics of forest biogeocenoses. An "express methodology for determining environmental and economic damage from forest fires" has been developed

In recent years, the following have been developed: classification of harems and fireflies on the lands of the forest fund; improved comprehensive indicator of fire danger in forests depending on weather conditions. Projects of forest fire zoning and local scales of fire danger according to weather conditions have been drawn up for a number of regions, and a methodology for fire protection of the forest fund territory has been developed. For the Chukotka Autonomous Region, Republic of In Sakha (Yakutia) and the Magadan Region, "Cost standards (regulatory and technological maps) for the protection, protection and reproduction of forests on the territory of the forest fund" were developed. The monograph "Fire situation in the forests of the Khabarovsk Territory" was published /Orlov, 2022/.

During its history, employees have received 11 copyright certificates for inventions, 1 patent, two bronze medals of the VDNH of the USSR, more than 430 scientific papers have been published, including five monographs, 6 PhD and one doctoral dissertation have been defended.
