Edge effects created by clear‐cutting on habitat use by sika deer on Mt. Goyo, northern Honshu, Japan

Abstract

AbstractClear‐cutting increased the species diversity and amount of undergrowth plants in a habitat of Sika deer (Cervus nippon) on Mt. Goyo, northern Japan. The number of species increased from 15 to 48 as a result of clear‐cutting. Among the plants, Sasa nipponica (a dwarf bamboo), an important forage plant for Sika deer, was predominant. Fecal pellets of deer were abundant in the forest and at the “adjacent zone” (from the edge to 150 m out of the forest) and thereafter decreased suddenly. The intensity of utilization of Sasa nipponica was also heavy in the forest, moderate at the adjacent zone and light 200 m from the forest edge. Since the amount of the bamboo in the forest was small, the removal of bamboo was greatest at the adjacent zone. Clear‐cutting creates a favorable feeding area for Sika deer in this zone by increasing the available plant production and securing forest cover.
