National Threatened Species Day

National Threatened Species Day (NTSD) is held on 7 September each year - commemorating the death of the last Tasmanian tiger at Hobart Zoo in 1936.

Events are held nationally throughout September - Biodiversity Month.

Australia's landscapes and species have been severely impacted by over 200 years of habitat loss and fragmentation. The impacts of land development, introduced plants and animals, grazing, salinity, changed fire regimes, pollution, and a changing climate all place additional pressure on our threatened species and their shrinking habitats.
