Effects of serpentine substrate on vegetation and soil development with special reference to picea glehnii forest in teshio district hokkaido japan

Effects of serpentine substrate on vegetation and soil development with special reference to picea glehnii forest in teshio district hokkaido japan

Characteristics of vegetation and soils in the serpentine area of northern Hokkaido were studied in comparison with non-serpentine areas of the same region, and with other serpentine areas of Japan and elsewhere in the world. The relationship between vegetation and soils is discussed. Although forest vegetation of northern Hokkaido is generally represented by deciduous forest, coniferous forest, predominantly Picea glehnii, develops in the serpentine area. Deciduous trees are limited both in number and in size. Forest floor is densely covered with Sasa kurilensis. The shrub layer is also well developed, whereas the herb layer is poor but contains characteristic species. Soils developing in the serpentine area are determined as Podzol (Wet Iron Podzol), while Brown Forest Soil is commonly found in the non-serpentine areas of the region. The serpentine soils as shallow and moist, showing general morphology and chemistry of podzolic soil in upper horizons of the profile. In lower horizons, however, physico-chemical properties are strongly affected by the parent rock. In comparison with other serpentine areas of Japan and elsewhere, northern Hokkaido is unique in that the vegetation is presented by a relatively closed forest of fair-sized trees, and the soils by a podzol. Such Picea glehnii forests and podzolic soils are considered an intrazonal phytogeocoenosis strongly affected by serpentine substrate. In this regard, the cool and humid climate as well as undulating relief of northern Hokkaido are also important factors for the development of the unique phytogeocoenosis.
