Why is biodiversity conservation important in NSW?

While progress has been made by establishing many public and private protected areas across NSW, we still need to do much more to conserve and protect our unique biodiversity, for four key reasons:

  1. There are many species still at risk of extinction: There are 932 plants, animals, algae and fungi that have been scientifically assessed as being at risk of extinction and listed as threatened under the NSW Biodiversity Conservation Act 2016. Of these, 526 are listed as endangered or critically endangered. There are 110 threatened ecological communities in NSW, of which 21 are critically endangered. We need more areas managed for conservation to see these species become secure in the wild in the long term. Find out more about NSW’s threatened biodiversity here.

  1. Native vegetation loss still threatens landscape viability: There are unique landscapes in NSW, known as Mitchell Landscapes. Over-cleared landscapes are defined as those with less than 30 per cent of their original extent remaining. Science has demonstrated that over-cleared landscapes will struggle and eventually fail to support agriculture or nature. These landscapes need to be protected and managed for conservation, and some may need to be restored to support viable ecosystems in nature in the long term.

  1. Major threats to biodiversity exist even in natural areas: There are many threats to our natural ecosystems, even where these haven’t been cleared for agriculture, urban areas or other development. The key pressures of habitat clearing and fragmentation, invasive species, and climate change remain the main pressures that threaten listed species and ecological communities, and biodiversity in general. So, we don’t just need remnant native vegetation left in the landscape; we also need conservation areas that are actively managed to eliminate or reduce the impacts of these threats to our plants, animals and ecosystems.

  1. Our reserves still do not represent the full suite of our diverse landscapes: Australia’s Strategy for the National Reserve System guides the development of the National Reserve System. The strategy establishes quantitative targets for comprehensiveness and representativeness. NSW is committed to building a comprehensive, adequate and representative (CAR) national system of protected areas. Only one of NSW’s 18 bioregions, the Australian Alps, has met C and R targets, and the South East Corner bioregion is the only other to have met R targets across its three subregions. According to the draft NSW National Parks System Directions Statement, we still need to protect examples of 335 NSW Landscapes in public or private protected areas to meet R targets in NSW. The NSW Government has set a target for the BCT to sample 120 under-represented NSW Landscapes in conservation agreements with private landholders by 2038. See our progress here.
