Case Study:

Stanford Population Survey

Animex drift fence lines were installed around multiple ponds as part of a multi-year pitfall trap study from Stanford University, monitoring the movement of breeding populations of California Tiger Salamander. Animex was also installed along a nearby busy road to direct wildlife to road undercrossings, allowing for safe passage between breeding sites. As a solid barrier, Animex promotes natural movement and prevents injury often associated with mesh fencing, making Animex a safe and effective choice for drift fence studies and road ecology.
