Distribution of nutrients (P, N, K, Ca, Na, Al) at different elevations in a forest ecosystem was examined in Oita Prefecture in 1987. The altitude and the forest type were as follows : 50 m-Campus of Nippon Bunri University : mixed forest of sweetleaf, sakaki and eurya, Akasako : pure forest of white cedar and cryptomeria : 300 m-Gosho Toge : pure forest of Japanese chestnut oak ; 820-850 m-Mt.Tsurumi : mixed forest of broad-leaved trees and pure forest of white cedar, coniferous and broad-leaved trees ; 1,050-1,150 m-Mt.Tsurumi : mixed forest of broad-leaved trees. The contents of Ca in the L-layer and of Al in the F- and H-layers decreased with the increase in the elevation, whereas the reverse phenomenon was observed for the content of Mg in the L-layer. The concentration of Mg increased with the elevation. The content of Ca in the trees decreased with the increase of the elevation. The content of K in the insects was highest at 50 m elevation and that of Ca in field mice decreased with the increase in elevation.
