PROBLEM TO BE SOLVED: To provide a device and a method for preventing feeding damage which contribute to a fundamental solution of feeding damage by grass-eating animals such as deer.SOLUTION: The feeding damage preventing device includes: a perforated plate 1 arranged so that it may cover the ground surface spacers 2 for separating the perforated plate 1 from the ground surface and for forming a plant growing space S between the perforated plate 1 and the ground surface and a load scattering material 3 arranged on the ground surface, is bonded to or connected with the spacers 2 and prevents the spacers 2 from sinking into the ground, so that plants having grown in the plant growing space S can get long through holes 1a in the perforated plate 1.COPYRIGHT: (C)2012,JPO&INPIT【課題】鹿等の草食動物による食害の根本的な解決に寄与する食害防止装置及び食害防止工法を提供すること。【解決手段】地面を覆うように配置される有孔板1と、有孔板1を地面から離間させ、有孔板1と地面との間に植物生育空間Sを形成するためのスペーサ2と、地面上に配置され、スペーサ2に接合または連設されてスペーサ2が地中に沈み込むのを防止する荷重分散材3とを備え、植物生育空間Sにおいて生育した植物が有孔板1の孔1aを通って伸長することができるように構成されている。【選択図】図1
