South Australia’s lesser-known threatened species

Today is National Threatened Species Day and this year we are shining a light on some of SA’s lesser-known threatened to extinction plants, fish, birds and mammals. 

By highlighting a species as threatened this helps rally resources and funding to conserve its existence locally. Pictured is the endangered woods well spyridium. Only 14 of these plants are remaining in the wild.

National Threatened Species Day is held annually on 7 September to raise awareness about Australian plants and animals that are at risk of extinction in the wild.

Since European colonisation it is estimated that 73 species – 41 plants and 32 animals – have become extinct in South Australia.

Today, South Australia has more than 1,000 species (828 plants, 324 animals) that are considered threatened at a state-level and about 200 at a national-level. This is because species that are threatened in SA can also occur in other states and territories, where they may be less or more of them.
