Five facts about frogs

Frogs serve as critical components of the food web and freshwater ecosystem health, acting as early warning systems for pollution due to their permeable skin. However, amphibians are currently the most threatened group of vertebrates, with approximately 41% of species facing extinction due to drivers such as disease, habitat loss, and climate change. WWF works globally to maintain river connectivity to ensure amphibians have access to breeding and feeding grounds.

• Frogs play a vital role in freshwater ecosystems by recycling nutrients and improving water quality through tadpoles eating algae, and they act as biological indicators of environmental health because their skin absorbs water and chemicals.
• Amphibians are the most threatened vertebrate group, with roughly 41% of species threatened with extinction. The primary drivers of this decline are disease and habitat loss, while other significant factors include pollution, climate change, invasive species, and over-harvesting for food and pet trades.
• WWF implements global initiatives to protect river connectivity—the linking of rivers, streams, and wetlands—to provide amphibians with necessary access to food, breeding sites, and refuge during dry periods.
