Personnel of the American Bat Conservation International have discovered that in a number of areas where the rain forest has been felled, within twenty minutes nearby fruit-eating bats have excreted indigestible seeds in their flight and greenery begins to appear on the disturbed, bare ground.
美國蝙蝠保護協會的人員就發現，在熱帶雨林地區，許多伐木後的空地，因為食果蝙蝠在鄰近覓食，不到廿分鐘，無法消化的種子，在飛行中就排出、掉落，童山濯濯之地不久又開始出現綠意。
