It is unknown how many echidnas there are in Australia and New Guinea, the only two homes of the echidna. The echidna is common throughout Australia because it is very adaptable and can be found in all habitats, from sub-alpine regions to hot, semi-arid and arid desert regions. All it needs to survive is a ready supply of ants and termites to eat.
Echidnas are generally solitary animals. They do not live in groups.
Given that echidnas have a conservation status of "least concern" throughout Australia, there are very likely to be as many echidnas in 5 years as there are now. It is unknown how many echidnas there are, but being a very adaptable animal that can survive wherever there are ants, it is expected the echidna has a very secure future.
