Abstract

The purpose of this study was to clarify the relationship between soil environment and the establishment and growth of Pinus densiflora in an early stage of revegetation after clear-cutting in P. densiflora forest of Futatabi Park in Mts. Rokko, Hyogo Prefecture, Japan. A small area (400m2) of this Pinus forest was clear-cut in 2004. We showed that sites within the park could be divided into four main types according to the dominant species (P. densiflora, Rhus javanica var. roxburghii, Rubus microphyllus, and grasses) in the sixth year after clear-cutting (cutting off at the ground followed by removal of litter and surface soil from the forest floor). P. densiflora seedlings had established at each site, and the number of seedlings at two site types (Pinus and Rhus sites) was higher than at the other sites. Maximum capillary-water capacity of surface soil was highest at the Rhus sites and lowest at the Pinus sites. Seedling growth of P. densiflora was highest at the Rhus sites where the canopy layer of Rhus javanica var. roxburghii shaded P. densiflora seedlings.
