| 内容記述 | Species compositions of the vegetation in fallows around a hamlet in a northwestern region of Malaita, the Solomon Islands, were quantitatively investigated over time after the abandonment of gardens (swiddens). The study site was situated in a tropical rain forest zone. The secondary succession began prior to the end of harvest activities of the farmers. The initial stage of natural regeneration following abandonment was characterized by very vigorous growth of such pioneer tree species as Euphorbiaceae and Ficus (fig). Within several years after abandonment, secondary forests of an early stage were established in the fallows where they were little disturbed by human activities. Many woody ferns grow there. At a stage of older than 10 years after the abandonment of gardens, the species composition was considered roughly similar to that at the stage several years after abandonment, although the relative value of the number of the pioneer trees of Euphorbiaceae plus Ficus was considerably decreased and both the quantitative indices of the number of tree individuals and the total area of horizontal breast height sections of their trunks in a plot increased. In the "Sanctuary Forest" which is considered to have been kept almost intact for several decades, not a few species of the common big trees in natural forests in the Solomon Islands were found. Both the foregoing quantitative indices there showed distinctly larger values than for the secondary forest of slightly more than 10 years fallow. Because of population pressure and, accordingly, the reduction of fallow periods to several years, the expansion of degraded grasslands or "fernlands" in the northwestern region of Malaita in the considerably near future is predictable despite much rainfall. |
