This study was conducted four ecological survey of field mice of Mt. Chuisuh in Yangsan City, Kyungnam from June, 2000 to March, 2001 for the understanding of field mice damage to forest. The results are obtained as follows. 1. The species of field mice collected were Apodemus agrarius, Apodemus peninsulae and Eothenomys regulus, and Crocidura suaveolens of insectvore. 2. The total collecting rate were 8.1% collected 61 individuals of field mice from 758 trap. 3. The rate among the 61 field mice collected were 45.9% in Apodemus agrarius, 29.5% in Eothenomys regulus, 19.7% in Apodemus peninsulae, and 4.9% in Crocidura suaveolens. 4. The constitution of weight of field mice was 16-51.9g in Apodemus agrarius, 12-25.9g in Apodemus peninsulae, 16-45.9g in Eothenomys regulus, and 12-15.9g in Crocidura suaveolens. 5. The sex ratio of field mice was 48.0% : 52.0% in Apodemus agrarius, 50.0% : 50.0% in Apodemus peninsulae, 55.6% : 44.4% in Eothenomys regulus, and 66.7% : 33.3% in Crocidura suaveolens. 6. The average body lengh was 104.33mm in Eothenomys regulus, 96.04mm in Apodemus agrarius, 94.50mm in Apodemus peninsulae, and 76.33mm in Crocidura suaveolens. 7. The average tail lengh was 92.75mm in Apodemus peninsulae, 80.65mm in Apodemus agrarius, 41.0mm in Crocidura suaveolens, and 40.33mm in Eothenomys regulus. 8. The breeding period of field mice in Mt. Chuisuh presumes from about the early of March to end of October. Specially, The Eothenomys regulus was ascertained the breeding period in December, discovered first time in korea through this experimental study. 9. The average litter size of field mice was 4.5 in Apodemus agrarius, 4.7 in Apodemus peninsulae, and 3.4 in Eothenomys regulus.
