Changes in the population density of sika deer in the Fudakake area, Tanzawa Mountains

Abstract

In 2011, we reported the population density of sika deer (Cervus nippon) in Fudakake of the Tanzawa mountains from 1998 to 2007. We continued investigating the population density of sika deer by the block-count method until 2015. Sika deer were captured for population management from 2007 to 2015 in the study area. We confirmed that the density of deer in the management period was lower than that in the non-management period. This result suggests that the number of deer decreased through capture in the study area.
