To investigate the structure and the conservation strategy of Taxus cuspidata forest at Janggunbong area in Taebaeksan, 18 plots(20m$\times $20m) set up with random sampling method were surveyed. Major woody species growing with Taxus cuspidata were Acer pseudo- sieboldianum, Euonymus macroptera, Prunus padus, Abies nephrolepis. High positive correlations was proved between abies nephrolepis and Pinus doraiensis, Betula ermanii and Magnolia sieboldii, and high negative correlations was proved between Acer pseudo- sieboldianum and Tripterygium regelii, Weigela subsessilis and Acer tschonoskii var. rubripes, Taxus cuspidata and Acer tschonoskii var. rubripes. Species diversity(H') of investigated area was calculated 2.3015(0.9991) and this value was relatively lower than that of other subalpine forest. Taxus cuspidata trees were severely stressed and vigor-lossed and 8.22% of surveyed Tacus cuspidata trees were dead tree. Dead trees were distributed mainly in 20~60cm DBH class and a few seedlings of Taxus cuspidata were observed. To conserve Taxus cuspidata forest at Janggunbong area in Taebaeksan, intensive research, prescription on the decline of Taxus cuspidata and proper forest management were needed.
