Part 5/9:
Road ecologists have identified four distinct categories of animal behavior in relation to roads: non-responders (like frogs), pausers (like turtles), avoiders (like cougars), and speeders (like deer). These behaviors inform the design of crossings to ensure they meet the needs of various species. For example, while some smaller animals might benefit from tunnels or culverts, larger species often require more expansive overpass structures capable of accommodating their size and behavioral characteristics.
