In many cases, fences are effective against human-wildlife conflict if the fences are properly constructed and maintained. However, wildlife is able to intrude fences where they intersect with roads. The purpose of this study was to evaluate techniques and strategies for improving the effectiveness of barrier fences in these vulnerable areas. This study developed the grates which are directly laid on the road. The grates used slanted steel panels which induce slippage of ungulate hooves down into the grates; therefore, ungulates cannot normally walk on the grates. To survey the best design of the grates, small-scale experiments were conducted in the forest. Seven types of grates were tested in four sites and the experiment showed that the most effective grates had 35° slanted panels and the distance between panels was 100 mm. Using the most effective grates, this study conducted an actual road test and the grates effectively reduced the deer passing the road (98.5% reduction). The advantages of our grates are (i) costs of digging and constructing a sub-footing using heavy machine is zero, (ii) < half-length of old type grates. Shorter grates (2.4 m) without sub-footings are safer for vehicles and walking children.

排解gr格作为防止作物破坏栅栏的附属设施

在许多情况下，如果围墙结构正确并得到维护，围墙将有效地抵御人类与野生动物的冲突。但是，野生生物能够侵入与道路相交的栅栏。这项研究的目的是评估在这些脆弱地区提高隔离栅有效性的技术和策略。这项研究开发了直接放在道路上的炉排。炉排使用倾斜的钢板，从而导致有蹄类动物的蹄子滑落到炉排中；因此，有蹄类动物通常无法在the子上行走。为了调查炉排的最佳设计，在森林中进行了小型试验。在四个位置测试了7种类型的炉排，实验表明，最有效的炉排具有35°倾斜的面板，面板之间的距离为100 mm。使用最有效的炉排，该研究进行了实际的路试，并且炉排有效地减少了通过道路的鹿（减少了98.5％）。我们的炉排的优点是：（i）使用重型机器进行挖掘和建造子立脚的成本为零，（ii）<旧式炉排的一半长度。不带底脚的较短格栅（2.4 m）对于车辆和步行儿童来说更安全。
