Federal agencies aim to establish a population of up to 25 grizzlies in the Northern Cascades over the next 5–10 years. The plan categorizes these grizzlies as a ‘nonessential experimental population,’ a status that mitigates human-grizzly conflicts by relaxing protections granted by the Endangered Species Act.

With a population of about 550 individuals in 14 fragmented populations, low genetic diversity undermines the species’ resilience to rabies and canine distemper virus outbreaks. In response, researchers directly introduce valuable genes across populations via artificial insemination and seek to build an African wild dog sperm bank.

Rewilding Portugal introduces a version of the extinct auroch cattle whose ancestors, depicted by paleolithic peoples in the region, played a key role in maintaining grassland ecosystems millennia ago. Now, their descendants will help establish a 1,200 sq km (463 sq miles) wildlife corridor along the Côa River.

Authorities plan to search for remnants of this predator that occurs only on this Indonesian island after recent observations, including the discovery of hair with matching DNA. Indonesia’s Ministry of Environment and Forestry plans camera survey efforts and DNA sweeps to corroborate these reports.
