Technical visit from New Zealand to Biological Reserve of Corvo

Although the tests to the anti-predator fence have been successful with regard to mice, the same was not true regarding rats and cats. In view of these difficulties, we found ourselves in need of resorting to Xcluder, a New Zealand expert team in erradications and anti-predator fences.


It was with this objective that during this weekend a technique of Xcluder, Jo Ritchie, visited Corvo Island. Meanwhile we were walking around the boundaries of Raven Biological Reserve where we want to build the anti-predator fence, Jo was indicating possible problems and consequent solutions due topographical features and the typical hard weather conditions of Corvo Island.

The concluding remarks we got from Jo were very exciting and hopefully we have the Biological Reserve of Corvo fenced and free of predators before the end of this year.


Greetings from Corvo.

Tests to anti-predator fence follow the right track!

As we wrote before, in early March had put a couple of wild mice Mus musculus into the area to test the anti-predators fence. Action that proved the effectiveness of our fence as a barrier to this species. Not so good results we had at the end of March to test the fence in relation to trasposability by cats.

Last Saturday we started testing whether the fence would work as an effective barrier to another species of predator introduced in Corvo Island - the Ship rat Rattus rattus (fig. 1). Once again the fence has proven effective. And our new tenant appears to be quite relaxed in their new home. Today we left another ship rat into the area to demonstrate the true effectiveness of the fence (fig. 2).

Meanwhile we have started improving our fence to test whether it can effectively contain cats as well.

Regards to all.
