Can 30 × 30 targets stop island extinctions?

The article discusses the importance of conserving biodiversity on islands and the inadequacy of the "30 × 30" target in preventing the extinction of highly imperiled island species. Two case studies are presented to illustrate this point. The first case study focuses on the Vangunu giant rat in the Solomon Islands, where only 7% of the island remains as habitat for the species. Despite efforts to protect this area, logging has been approved, which could lead to the extinction of the rat. The second case study examines the Rennell flying fox, endemic to Rennell Island in the Solomon Islands. Although almost 30% of the island is protected as a World Heritage Site, the species has not been observed since 2021, suggesting that protection measures have been insufficient. The article argues that a more nuanced approach to conservation is needed, taking into account the unique characteristics and vulnerabilities of island biotas. [Extracted from the article]
