Possible solution for the fox problem?

Australian Wildlife Conservation has a number of cost effective, non-electric fence exclusion options that may be worth exploring as cage trapping, which is the least effective of all options, is still an expensive way of trying to eliminate a fox.

They have tried these for the Bush Stone Curlews and have had success. See page 12 but without electric fence.

AWC were inspiring as they seem to have had better outcomes for less money in terms of conservation measures.

It may be the new solution for an urban area where there is endangered fauna in need of protection. There are many more effective fox elimination solutions but because we are in a fairly urban area, they can't be undertaken. Exclusion may be the only way.

The fence option seems to be in line with the cost of cage traps, which has many downsides.

I need to obtain permission from Office of Environment and Heritage as the Oystercatchers are protected by law.

Hoping they will allow that we have the experience and people to manage it to obtain approval.

Really there is nothing to lose as leaving them to try nest on their own has not so far worked. It may be time to try something new and maybe it can be applied to other sites if successful.
