描述: To evaluate the conservation status of Taiwan's mikado pheasant, <italic> Syrmaticus mikado</italic> (Phasianidae), I test the similarity of preferred habitat to primary and secondary forest, develop models of habitat availability within Taiwan, and examine population trends within two locations inside Yushan National Park. The characteristics of locations with pheasant activity were most similar to secondary forest: high shrub stem counts and low canopy and leaf litter coverage. None of these variables were applicable to geographic information systems analysis. To the known extent of range and area of occupancy, I compared a model based on the habitats described in field guides. This model underestimated extent of range, confirmed that 39% of the pheasant's range is protected inside parks and reserves, and suggest that Taiwan potentially has 6477 km<super>2</super> of habitat available to <italic>S. mikado</italic>. Within Yushan National Park, there may be as many as 10,000 <italic>S. mikado </italic>. The small home ranges (<0.86 km<super>2</super>) and the lack of movement across the 400 m separating the study sites imply limited gene flow between populations and poor ability to colonize suitable habitat. There were 58 pheasants per km<super>2</super> in the primary forest site and 48 in the secondary forest site. At the primary forest site, the population appeared stable. At the secondary forest site, the population declined 65% from 3.56 pheasants encountered per day in 1989–1992 to 1.24 in 1996–1999 due to poor productivity because of increased numbers of nest predators (from 1.4 predators per day to 2.2) and the cooler weather conditions during hatching. In 1989–1991, most rainfall was in the last week of June, but rainfall was evenly distributed throughout May and June of 1996–1998. Poaching, a threat to adult pheasants, increased during this time from 0.06 incidents per day to 0.23. As the pheasant lives at elevations naturall
