Pinch Point: Any portion of a migration or movement area in which animal movements are physically or behaviorally funneled or constrained by natural or man-made landscape features, and a significant number of animals move through. Loss of these areas now, over time, and/or cumulatively in the future, could disproportionately compromise habitat connectivity (migration and/or movement) because alternate routes are limited, unavailable, or increase risks and energetic costs of migration. Examples may include habitat leading to a highway underpass, overpass or natural land bridge; a gap or break between impermeable fences; space between ex-urban residential or other land use developments; steep cliffs, canyons, drainages or other geographic features; or a route that circumnavigates a lake or reservoir.瓶颈点（Pinch Point）指迁徙或移动区域内，因自然或人工景观要素使得动物移动在物理层面或行为层面被汇聚、约束，且有大量动物途经的任意区段。当前、随时间推移或未来累积性地丧失此类区域，可能会不成比例地损害栖息地连通性（迁徙及/或移动），因为替代路径有限、不可获取，或会增加迁徙的风险与能量消耗。示例包括通往公路下穿通道、上跨天桥或天然陆桥的栖息地；不可穿越围栏之间的空隙或断点；远郊住宅或其他土地开发项目之间的空间；陡峭悬崖、峡谷、排水沟渠或其他地理地貌；或是绕行湖泊或水库的路径。
