Abstract
The aim of this study is to characterize the long-term researches in permanent plots by researchers of institute and the ways of use the new results. Data from scientific publications of institute researchers are the source of this paper. The brief history of stationary researches of URIFFM is highlighted. Its research network includes now two Branches, six Research Stations and one Department. Attention is paid to content and recent results of long-term investigations in the permanent sample plots of URIFFM and its Research network on issues of forestry, forest breeding, monitoring and protection. It was stated, that the sense of long-term stationary researches is in the regularly repeated assessment of the same parameters by the same methods in the network of permanent sample plots. Parameters of soil, condition of plants and animals (including insects) as well as disturbances frequency and severity are registered simultaneously. It was stated, that succession of generations of scientists is characteristics for long-term researches. Recent results for experiments on thinning started by B. I. Gavrylov in 1932, provenance tests started under guidance of V. D. Ogievsky at the beginning of the XX century and of I. M. . Patlaj in the 70-ties of the XX century are highlighted. The summary on other kinds of forest breeding objects, particularly gene reserves, plus stands and plus trees, progeny tests, clonal and seed plantations is presented. Peculiarities of researches on the Ist and IInd Levels monitoring, as well as local monitoring of forest condition under action of recreation, fire or insect damage are presented. Disadvantages of organization of stationary researches are described, which are connected with lack of funds for regular site visits, and inability to equip the permanent plots with modern instrumentation.
