| Outline of Final Research Achievements |
The objective of this study is to establish accurate and cost-effective approaches to estimate population size or density of Sika deer using camera traps and UVAs. For the former, we performed 3-D modeling on antler of male Sika deer and recognize the individuals to apply capture-recapture model. For the latter, we flew a UVAs in a forest in Gumma prefecture to test whether animals are recognizable from the air. The results showed that both methods are potential to estimate the density of Sika deer, although several constrains should be solved. In particular, a combination of individual recognition by camera traps by 3-D modeling and capture-recapture model are an efficient approach to estimate Sika deer's density.
