Turallo Nature Reserve protects one of the region’s best examples of Natural Temperate Grassland of the Southern Tablelands, an endangered ecological community listed under Commonwealth legislation. It has a particularly high native plant species richness, with around 100 species being recorded.
A number of threatened fauna have also been recorded in the reserve, including the diamond firetail, little whip snake, and the Canberra raspy cricket (listed under ACT legislation). It also contains a rare large green weevil which has not been recorded in recent years except in the reserve.
