It is on a mountain in Greece, not an island. Still to this day woman are not allowed on the mountain. It has like a special status like a dwarf state but not fully, it's complicated.
But I have never heard of them having the same rule for lifestock, that could be made up by this guy, I don't know. Just saying it's possible. But yeah you're right, it would be impossible to completely controll for wildlife. But they may not care about a bird or rodent, just not counting that?

It is on a Greek mountain peninsula however there are no roads leading to it so only way there is by boat. They do have a strict no female animal policy and import only male goats and sheep.

The Greek church that runs this place was sued in 2005 when a female French tourist was denied access. The EU court ruled in favor of the church as their no female policy had been in effect since before the EU even existed
