This report presents the key findings from a comprehensive evaluation of representation gaps for high conservation value aquatic species, ecosystems and habitats (biodiversity assets) in the Murray–Darling Basin. The study aimed to assess the protection status of biodiversity assets within existing area-based conservation measures and identify gaps that require urgent attention.
The analysis focused on the representation of biodiversity assets inside area-based conservation measures, the correlation between asset size and protection, and a vulnerability assessment of assets to climate change. The results provide valuable insights for prioritising conservation efforts and guiding future management decisions.
Key findings / recommendations:
Part 1: Representation Gap Analysis
-
The evaluation revealed that the Basin demonstrates low protection, with 14% of the area falling within existing protected areas, key biodiversity areas (KBA), or Ramsar wetlands. Additionally, 24% of the basin is potentially waterable, and 4% falls into both protected and waterable categories.
-
The study found a significant correlation between biodiversity asset size and protection, with larger assets exhibiting higher representation within protected areas, KBA, or Ramsar wetlands.
-
These findings emphasise the need for targeted conservation efforts to address the representation gaps and enhance the protection of important biodiversity assets within the Basin.
Part 2: Vulnerability Analysis
-
Our findings highlighted areas where significant climate shifts are expected to occur. We identified biodiversity assets within these regions that are likely to experience notable climate changes (temperature and precipitation).
-
This vulnerability analysis provides valuable insights into the potential impacts of climate change on biodiversity assets within the Basin.
