How long have poison dart frogs been endangered?

Poison dart frogs have been facing threats to their populations for several decades, primarily due to habitat loss, climate change, and pollution. While specific conservation statuses vary by species, many have been classified as endangered or vulnerable since the 1990s. Loss of habitat due to deforestation and the pet trade has significantly impacted their numbers. Conservation efforts are ongoing to protect their habitats and raise awareness about their plight.
