<p>This paper will clarify the status of national parks and the characteristics of their systems through an analysis of the Special Nature Conservation Area Law (N33-FZ), which forms the basis for the nature protection system in the Russian Federation. The changes of their systems since the 2000s are as follows. According to a 2013 amendment to the law, the management and operation of national parks is now the responsibility of the independent administrative agencies. National parks have private lands, indigenous peoples, and other residents, and articles have been added to take their rights into consideration, and they are divided into six zoning categories that reflect these rights. In recent years, several specific prohibitions have been added to the national park articles, likely reflecting increased use pressure. On the other hand, the system was revised to be more conducive to use, allowing land to be leased to individuals or corporations.</p>

(1) Background: In Japan, single-tree selection-cutting silviculture with hiba (Thujopsis dolabrata var. hondai) is a traditional silvicultural system and is well documented. We evaluated an experimental forest regarding past structural dynamics and future development while comparing it to the German multilayer coniferous “Plenterwald/plenter forest”. (2) Methods: Classical growth and yield data were recorded since 1995 from two hiba-mixed species plots, one managed since Matsukawa’s (the founder) times in 1931 and the other unmanaged since 40–50 years before 1931. (3) Results: Clear structural differences appeared, with the managed plot having a reverse J-shaped DBH and tree height distribution curve, and a higher percentage of hiba, also typical for German plenter forests’ intensely multi-storied structure. The unmanaged plot was composed of trees with large stem diameters, even though they were more evenly distributed, together with less admixed species. In both plots, the growing stock increased in the past. While the managed plot’s growing stock in 2019 was 561 m3 ha−1, the unmanaged plot reached 982 m3 ha−1 with large portions accumulated in DBH classes >60 cm. (4) Conclusions: When compared to today’s clearcutting system in Japan, selection silviculture shows advantages and may thus serve as a valuable inspiration for silviculture in Japan as it was with plenter forestry for Germany.
