The geographical distribution and the abundance of Moose(Alces alces)popula-tion were studied in Northeastern China between 1985 and 1987,309 trails on the snow crossingthe 2,446km sampling lines were counted.The Moose range had been shrunked to northwest for100-200 km since 1976,and at present they covered an area about 190,000 km^2.The densitiesvaried from 0.0187 Mooses/km^2 to 0.1226 Mooses/km^2 and the average was 0.0519Mooses/km^2.The Moose population size was 9,955±397 Mooses(α=0.2,P=84.5%),about7000 of them was distributed in Daxinganling Mountains and the others were in XiaoxinganlingMountains.The present population had decreased to 53.4%in 1976,and the annual decreaserate was 6.27%.At present,Moose population is likely rare in China and should be strictly pro-tected.
The geographical distribution and the abundance of Moose (Alces alces) population were studied in Northeastern China between 1985 and 1987, 309 trails on the snow crossing the 2, 446km sampling lines were counted. The Moose range had been shrunked to northwest for 100-200 km since 1976, and at present they covered an area about 190,000 km^2. The densities varied from 0.0187 Mooses/km^2 to 0.1226 Mooscs/km^2 and the average was 0.0519 Mooses/km^2. The Moose population size was 9, 955 ± 397 Mooscs (α = 0.2, P = 84.5%), about 7000 of them was distributed in Daxinganling Mountains and the others were in Xiaoxinganling Mountains. The present population had decreased to 53.4% in 1976, and the annual decrease rate was 6.27%. At present, Moose population is likely rare in China and should be strictly protected.
