Colorado lawmakers have green-lighted a bill that paves the way for re-establishing wolverines while learning from the state’s recent wolf reintroduction. This bill does not have a strict deadline for the release of wolverines and it includes a compensation program for ranchers who lose livestock to these elusive carnivores.

A groundbreaking transboundary survey along the Zambezi River by Zimbabwe and Zambia found that hippo populations are declining. The likely culprits are shortages of grazing caused by drought along with human disturbance. The study is expected to guide the management of human-hippo conflict and the development of hippo conservation strategies.

A recent study found that Munich (Germany) residents’ preferences for animals correlate with their tolerance for living alongside them. While a handful of mammals, including squirrels, are well-liked and accepted as “neighbors,” others, such as martens and rats, are less popular and residents prefer them to stay farther away. Acknowledging these social preferences may lead to more successful urban biodiversity.

An analysis of 665 metrics to assess conservation success across 186 studies shows that global conservation efforts are paying off. Overall, 45% of these metrics showed an improvement in biodiversity and 21% had at least slowed the decline in biodiversity. Removing invasive species and protecting habitats are among the most effective strategies, suggesting that the remaining barrier to further progress is funding.
