Abstract:The north slope of Mt. Changbaishan natural forest of China is endowed with important Korean pine provenance base. However, in recent years, this pine plantation has been seriously infested with pest rodents. This prompted our field survey, from April to October 2015, to ascertain the scale of damage and the criteria of damage on tree species located in five forest types including: the Broad-leaved forest, Coniferous and broad-leaved mixed forest, Coniferous forest, Dark coniferous forest and the Yuehua forest. In addition, we also surveyed twice in damage forest type, to justify on the composition and density of rodents in the above it, using the bucket trap and the live-cage trap in spring and autumn. Results showed that: 1) pest rodents only occurred in Coniferous and broad-leaved mixed forest during winter at the altitude of 800-1100 m, 2) the damage percentages on trees species were markedly observed on local and economically-valued trees, which included: Tilia tuan (3.61 ± 1.05) %, Acer pseudo-sieboldianum (3.00 ± 0.63) %, Pinus koraiensis (1.7 ± 0.31) % and A. mono (1.28 ± 0.14) % etc, and these damages mostly affected plant parts on stem base (58.90%) and bare root (37.99%). The spring rodent density was higher in the North Slope of Mt. Changbaishan forest area, but it was lower in autumn. The captured rodent species mainly included: Myodes rufocanus, Apodemus peninsulae and M. rutilus. The bucket-trap capture rate for M. rufocanus was 7 times higher than live-cage trap, while it was lower than live-cage traps for A. peninsulae and M. rutilus capture, respectively.
