Promotion of plant species diversity of artificial plantations in Korean national parks through thinning

다국어 초록 (Multilingual Abstract)

A considerable area of plantation existed in the Korean national parks. Issues such as heterogeneity withthe surrounding environment and susceptibility to disturbances have been raised. Therefore, Park Serviceimplemented a large-scale thinning practice with 15 parks and monitored the effects for five years. Wemeta-analyzed the five-year report of six parks and evaluated the effects on the biodiversity of herbaceousstratum. Repeated measures ANOVA showed that the number of plant species increased significantlyover time particularly from the fourth year. It differed significantly among thinning intensities andparks. In heavy thinning ( 60%), it was twice higher than reference after one year, and the differencebecame larger over time. The coverage of the herbaceous stratum tended to be higher; however, it wasnot significantly different. Especially, after 5 years, both the number of species and coverage were higherthan the reference in all thinning treatments. The proportion of short-lived species was significantlyhigher after one year in heavy thinning but was not significant after 5 years. Overall, this thinningpractice increased biodiversity in plantations without letting proliferation of alien or disturbing species.
Thus, thinning practice was successful that led to species composition similar to that of the naturalforests.
