Testing predators-proof fence of Corvo's Biological Reserve

As we have mentioned before, last year we began testing a fence to use around our Biological Reserve Corvo. In December 2009, the employees of the Corvos's Council built the test-fence, 6 by 3 meters.



In January we started testing the test-fence by inserting 2 wild mouses Mus musculus within the fenced area to realize whether it's able to contain this species. Was installed a camera with motion sensor (IR) to capture possible leakage.

Despite initial failures, it seems that we finally got a wild mouse-proof fence. After some design changes on the test-fence on last Wednesday, February 10, we insert again 4 individuals in the fenced area, none of which managed to cross the test-fence until today.



This step represents an important victory in the construction of a fence impenetrable by predators of seabirds.

The test has followed all animal welfare rules.
