Animal Crossing: For Those That Cannot Fly

A structure that allows small animals to cross an obstacle. Underneath the road or channel, there is a dry box culvert passage, with the same soil and fallen leaves as at both ends, and continuous dry platforms on both sides. At the entrance, low guiding fences lead animals over, with no gaps between the fences and the passage opening. Both ends of the passage are fully vegetated, not concrete clearings.
Avoid: Having a smooth concrete interior for the passage, making the passage long and dark without mid-section lighting, having a break between the guiding fence and the passage opening, installing lighting at both ends of the passage.

一處讓小動物穿越障礙的構造。道路或渠道底下有一個乾燥的箱涵通道,內部鋪著與兩端相同的土與落葉,兩側有連續的乾燥平台;入口處以低矮的導引圍籬把動物引導過來,圍籬與通道口銜接沒有缺口。通道的兩端都是完整的植被,不是水泥空地。避免:讓通道內部是光滑的混凝土、把通道做得又長又暗沒有中段採光、讓導引圍籬與通道口之間有斷開、在通道兩端設置照明。
