Outline of Final Research Achievements

We evaluated the effects of retention harvesting on ecosystem survices such as water and soil conservation, insect damage control and edible wild plants provision in a large-scale retention foresty experiment in fir plantations in Japan. For water and soil conservation services, water discharge and nitrogen runoff one year after harvest were affected by retention levels of broad-leaved tress in each experimental plot. For services to protect insect damage, avian predation on artificial caterpillars did not correlate with small bird density. Also, growth rate of todo-fir aphids (Cinara todocola) on fir seedlings differed with ant species that attended colonies of todo-fir aphids. For the provision of edible wild plants, we determined the change in the abundance of these plants after harvest and estimated the economic value of these wild plants.
