Temporary Fencing

Lightweight, reusable wildlife barriers.

Project Duration Suitability: Up to 5 years

Our low-impact temporary wildlife fencing has been the exclusion barrier of choice for biologists and contractors since 2005.

The Animex anti-climb technology embedded in its recycled plastic formula makes it the most durable and environmentally friendly animal control fencing available. Animex fencing can easily be recovered and reused on multiple projects.

Case Study:

Twitchell Island DMPS

  • Location: Twitchell Island, California
  • Species: Western Pond Turtles (Emys marmorata) & Alameda Whipsnakes (Masticophis lateralis euryxanthus)
  • Fence: AMX T40 (Free standing)

Animex installed temporary exclusion fencing to enclose the construction of a dredged material placement site (DMPS) in support of maintenance dredging in the Stockton Deep Water Ship Channel (DWSC). The 35-acre DMPS was established on Twitchell Island, adjacent to restored wetland habitat known to be inhabited by Alameda Whipsnakes and Western Pond Turtles. The fence was installed at an angle for one-way movement, serving as an effective exclusion barrier while allowing animals to escape the active construction zone. Following construction of the DMPS, the fence was removed and disinfected to be used for future projects.
