Research Abstract

We evaluated the effects of selection harvesting on forests in Hokkaido, northern Japan, based on the long-term ecological monitorings in combination with recent field surveys. In stands located in northern Hokkaido, the effects were generally negative (Yoshida et al. 2006), especially for recruitment of juvenile trees (Noguchi and Yoshida 2007). The differences in the response among species were examined in detail, with emphasis on particular sensitive species.
Nevertheless, these trends were appeared to be region-specific, as the contrasting results were obtained in stands in eastern Hokkaido. In the management, we should note such a difference, probably caused by difference in climate condition and the corresponding understory vegetation (e.g. existence of dwarf bamboos in northern stands). We also found significant positive effects of soil-disturbances, which should be associated with harvesting, on recruitment of juvenile trees (Nagai and Yoshida 2006).
Finally, we examined to apply these data to a spatially explicit individual-based simulation model, which is valuable to increase the feasibility of a sustainable management. Although we need further improvement for this model, we have obtained sufficient datasets to estimate significant parameters, including the individual responses of trees to disturbance (Kubota et al. 2006), for multiple regions with different ecological characteristics. Based on a preliminary trial, we documented Japanese papers for stakeholders regarding regional forest management. The suggestions shown there will be further developed by improving the simulation model, and they will contribute greatly to sustainable resource management in Hokkaido.
