An excellent site for wildlife friendly fencing as it relates to cranes. Here the issues relate more to the ability of wildlife to move freely across the landscape, rather than entanglement, although this too occurs. There is a policy in many areas to fence off wetlands from cattle, and thereby reduce the impact of cattle on water quality and erosion. However this has serious consequences for cranes. They require a large area in which to run in order to take off and fly. They also require large expanses of shallow water in which to feed, breed and roost. Sites that are overgrown with rank grasses or shrubby vegetation, through an absence of grazing or fire, will ultimately exclude cranes.
