A little-known plant only found on a tropical peninsula could go extinct if a planned gas and petrochemical hub goes ahead, an environment group says.
Documents leaked to the Environment Centre NT show the Middle Arm project on Darwin Harbour would destroy 86 per cent of the endangered plant's remaining population.
The leaked assessment comes from the Northern Territory government's own draft environmental impact statement on the project.
The tiny herb, Typhonium sp. Cox Peninsula, was one of 35 plants and animals added to Australia's list of national threatened species in February.
The Environment Centre NT said the plant could go extinct due to land clearing on the Cox Peninsula if the proposed Middle Arm hub goes ahead.
The Middle Arm project would also harm critically endangered far eastern curlews and endangered black-footed tree rats, the environment centre said.
