That report from Goodnature (oh how I hate that name!) sounds interesting. To put a link on here it has to be located somewhere else on the internet, such as flickr or Twitter etc. Pinterest is also a possibility; I put a link to the BHPS petition on there yesterday.
I just did a search on Google to see if I could find out any more information on the A24 trap and that trial you mention. I couldn’t find the trial, but I found some other interesting information. According to the authorities in New Zealand where the trap was originally developed to exterminate our prickly friends, out of all the predators which pose a threat to their native wildlife, hedgehogs were at the bottom of their list, posing a threat only to shorebirds and possibly SNAILS! The six other predators on the list which posed much higher threats included cats, dogs and pigs! Cats posed a potential risk to sixteen other species, pigs seven and dogs six. Does that mean that household pets will be next on their hit list then…just a thought!
