The entry. The separate aspects of problem of a search and estimation of rare forest associations are reflected. Marked expedience of use of the special analysis of structure of forest fund on the previous stage of their search.Along with the role of forest vegetation formations in the preservation of forest ecocenosis biodiversity, the problem of preserving rare forest plant for mations has become the most topical in the first halt of the19 st. century.The purpose and objectives of research. Moreover, the solution of the problem is impossible without the preservation of rare and vanishing species. Numerous investigations into rare forest plant formations can be observed both inUkraineand the world over. Thy can serve the basis for the theoretical principles related to the above formations conservation and protection.The methods. When assessing rave plant formations and determininy the efficiency of their protection, one can observe the tendency ot enhancif the role of guantitative methods.The results. One of them was suggested by J. Loidi ioho defines rarity as afunction of medium distancebetween plots covered with the formations of one association. Conjugation analysis of geographic ranges of edyfikatoriv these groups will help to clarify the nature of their rarity . For example, groups sporadically presented within a limited area of research in a small area and formed edyfikatorom , geographic area which coincides with the territory, it is necessary to evaluate how the rare worldwide. If edyfikatora geographical area is broader (eg, extends within the entire continent), these groups need to classify regionally rare and so on. A similar approach should be used to identify and assess the value of old-growth stands (by analysis of the age spectrum stands), with occasional asektatoramy groups (by analysis of plants) and others. For the final assessment of the nature rarity forest communities represented in the study area in a small area, it is obligatory to establish their spatial location in Maps forests in Ukraine are available for each forest management, the implementation of field studies to identify their vintage components (plants and animals listed in the red Book of Ukraine, the European red List (1991), the regional lists of species to be protected, endemiv etc.) as well as the involvement of other additional features.The conclusions. The ultimate assessment of rarity of plant formations presented in the region of investigation reguires. The use of database technology enables you to select according to various criteria actually rare communities (sporadically distributed plantations, which occupy a small area). Assessment of the nature of their rarity advisable to perform the further additional studies./p
