1/ 📢Yesterday saw the release of our analysis of the first @IUCNRedList global freshwater fauna assessment in @Nature ! The dataset took 1000+ experts 20+ years to compile. So what did we find? https://t.co/TxS0kUkFLL

BREAKING NEWS: The number of #fungi species on the IUCN Red List of Threatened Species™ has surpassed 1,000.

The latest update confirms that #deforestation, agricultural expansion and urban development are driving these species to decline worldwide.

ICYMI the first global #freshwater fauna assessment for @IUCNRedList found one quarter of freshwater animals are threatened with extinction 🦐🐟🦀 Read online and now out in print in @Nature https://t.co/AMDraHB0hK

[UN Biodiversity @UNBiodiversity]

Freshwater landscapes are home to 10% of all known species on Earth but a new IUCN co-authored study reveals 1/4 of freshwater animals at risk of extinction 

It is the largest global assessment of freshwater animals on the @IUCNRedList to date

Wetlands provide us with clean water, biodiversity and climate resilience. Yet, we are losing them far too quickly. Protecting and improving the management of these ecosystems is critical for our future.

9/ We hope this dataset & recommendations from our paper will be integrated into evidence-based conservation, management & policy measures. Let’s bend the curve for freshwater biodiversity loss! https://t.co/TxS0kUkFLL

8/ Why should we care? Freshwaters are highly biodiverse and are key for ecosystem services, human livelihoods & economies. They must be protected for nature and people alike.
