Abstract

Spatial distribution and tree height of landscaping tree species that escaped from man-made landscape were investigated in 31 fragmented secondary forests in Flower Town of Sanda City, Hyogo Prefecture. A total of 22 species and 2,385 individuals were distributed in the forests, and most of them were ornichorous tree species. Almost all the landscaping tree speceis were seedlings or saplings. Ornithochorous tree species, Rhaphiolepis umbellata and Lignstrum lucidum, were mainly distributed within 100m from the nearest mother tree planted around the forests, while barochorous tree species, Castanopsis cusp id a ta var. sieboldii and Quercus my rsinaefolia, were mainly distributed within 30m. These distributional patterns seem to reflect their seed dispersal patterns. We discuss the planting methods of ornichorous tree species for conserving fragmented forests.
