# Mosses of Western Australia

Western Australia has relatively few species of moss; the most recent census found just 192 taxa. This represents just 10% of Australia's total moss flora, even though Western Australia accounts for about one third of the Australia by area. This relatively low diversity has been attributed to the lack of rainforest in the state.
By far the majority of the state's moss species occur in the Southwest Botanical Province, with over 80% of all species, genera and families occurring there. This includes four species that are apparently endemic to the province.
About 70% of Western Australia's moss taxa occur also in South Australia, and a similar proportion occur also in New South Wales. Only about 50% occur also in Queensland. About half are restricted to Australia, New Zealand and South Africa, and a further 10% occur also only in South America.
