Fences


Howard B. Eskin

While fences effectively define perimeters and property lines, they also fragment habitats by limiting the movement and range of plants and wildlife. Properties are able to support more wildlife when wildlife can wander over a greater stretch of land unimpeded by restrictive fences.

Why are fence considerations important to birds and the environment?

Fences on ranchettes or other large-tract properties might serve to exclude wild animals; to contain domestic animals, including pets and livestock; to alter the appearance of the property; or to protect or divide one's property. However, fences limit the movement and range of some wildlife, or pose the risk of injury or death to others due to entanglement. The huddling of livestock on critical wildlife habitat can lead to the degradation of potential habitat by overgrazing or to the trampling of ground-dwelling birds and their nests.

The need for a fence must be evaluated based on land use and the long-term property management goals: Will livestock or row crops be kept? Is temporary fencing an option? Can fencing be reduced or eliminated altogether? If fencing is used, the placement, material, and design should be carefully considered for the maximum benefit of existing wildlife.

Getting Started: What You Can Do

  • Fence only the amount of area absolutely necessary.
  • Know the wildlife that uses your property and design fences accordingly. See web links below for information on fence design and the needs of specific wildlife.
  • Paint the tops of fence posts white, and flag new fencing to make them visually apparent. Barriers need to be easily seen, especially in areas of seasonal wildlife movement; wooden fences are preferable.
  • Use smooth wire instead of barbed wire, so that animals won't become trapped; keep the wire taut and use as few strands as possible.
  • Fence livestock 30 to 60 yards away from wetland areas so as not to discourage waterfowl nesting.
  • Work with natural resource officials, who can offer guidance and information.
