Yes, bandicoots are now considered endangered in Australia. One source says that prior to the time of European settlements arriving in Australia, there were believed to be nine species of bandicoot. Two species are now considered extinct and four species are threatened with extinction. That would leave 3 species but the numbers don’t seem to add up. There are several conservation organizations working hard in Australia to preserve and protect the bandicoots.
Reasons leading up to this sad situation include the destruction of their native grassland habitat forcing bandicoots to compete for food with rabbits. Also, the Europeans brought with them foxes, cats, and dogs which prey on bandicoots.
