When did black rhino became endangered?

Black rhino became endangered due to excessive poaching and habitat destruction. The primary reason for their endangerment is the high demand for their horns in illegal wildlife trade. Rhino horns are erroneously believed to hold medicinal properties, leading to a lucrative black market. Additionally, habitat loss due to human activities such as agriculture, logging, and human settlement has further exacerbated the decline of black rhino populations.
