Short-term effects of thinning on the growth and stand characteristics of Scots pine (Pinus sylvestris L.) plantations in northern Mongolia
This study was conducted to investigate effects of thinning on the tree growth and stand characteristics in Pinus sylvestris plantation forests, northern Mongolia. Three study sites were located in the Tujiin nars area, in 18- to 20-year-old plantation forests that were thinned in 2016 and 2017, res...

| description | This study was conducted to investigate effects of thinning on the tree growth and stand characteristics in Pinus sylvestris plantation forests, northern Mongolia. Three study sites were located in the Tujiin nars area, in 18- to 20-year-old plantation forests that were thinned in 2016 and 2017, respectively. In each site, three plots in thinned and an unthinned (control) plot were established to examine changes in growth and stand characteristics. Thinning induced an increase in diameter increment and it was strongly correlated with annual precipitation and year of planting at all sites. The effects of thinning on height growth were insignificant. Crown morphology differed significantly between thinned and unthinned stands; thinning increased crown diameter and crown projection area but mean crown length and crown form index were higher in unthinned stands. |
