Research published in the American Journal of Primatology earlier this month finds that the overall Western Chimpanzee population declined by six percent annually between 1990 and 2014, a total decline of 80.2 percent. The main threats to the Western Chimpanzee are almost all man-made. Habitat loss and fragmentation driven by slash-and-burn agriculture, industrial agriculture (including deforestation for oil palm plantations as well as eucalyptus, rubber, and sugar cane developments), and extractive industries like logging, mining, and oil top the list. In response to the finding that the Western Chimpanzee population has dropped so precipitously in less than three decades, the International Union for the Conservation of Nature (IUCN) elevated the subspecies' status to Critically Endangered on its Red List of Threatened Species.

Global trade has made it easier to buy things. But our consumption habits often fuel threats to biodiversity - such as deforestation, overhunting and overfishing - thousands of miles away. Now, scientists have mapped how major consuming countries drive threats to endangered species elsewhere. Such maps could be useful for finding the most efficient ways to protect critical areas important for biodiversity, the researchers suggest in a new study published in Nature Ecology & Evolution. For example, the maps show that commodities used in the United States and the European Union exert several threats on marine species in Southeast Asia, mainly due to overfishing, pollution and aquaculture. The U.S. also exerts pressure on hotspots off the Caribbean coast of Costa Rica and Nicaragua, and at the mouth of the Orinoco around Trinidad and Tobago. European Union's impacts extend to the islands around Madagascar: Réunion, Mauritius and the Seychelles. The maps also revealed some unexpected linkages. For instance, the impact of U.S. consumption in Brazil appears to be much greater in southern Brazil (in the Brazilian Highlands where agriculture and grazing are extensive) than inside the Amazon basin, which receives a larger chunk of the attention. The U.S. also has high biodiversity footprint in southern Spain and Portugal, due to their impacts on threatened fish and bird species. These countries are rarely perceived as threat hotspots.

Bordering Myanmar on the southeast and the Indian states of Tripura on the north and Mizoram on the east, the Chittagong Hill Tracts (CHT) is one of these areas. Characterized by semi-evergreen forest that is considered part of the highly endangered Indo-Burma Biodiversity Hotspot, CHT is a refuge for at least 26 globally threatened species, making it a critical conservation priority. But conservation efforts in the region have historically been challenged by the very remoteness and political instability that have helped protect it from deforestation seen in other parts of Bangladesh. That protection is now disappearing with the influx of settlers from other regions who are increasingly clearing forests for agriculture, logging trees for timber and firewood, and hunting wildlife. In other words, time is running out for Bangladesh's last rainforest and its traditional tribes.

Increased conservation advocacy by groups including the Leonardo DiCaprio Foundation and the World Wildlife Fund encouraged the Mexican government to renew efforts to save the critically endangered vaquita porpoise from extinction. Mexican President Enrique Pena Nieto has signed a memorandum of understanding that includes stricter enforcement of a permanent ban on fishing nets in Mexico's Upper Gulf of California, where about 30 vaquitas are estimated to be left.

A new study calculates that the island of Borneo lost nearly 150,000 orangutans in the period between 1999 and 2015, largely as a result of deforestation and killing. There were an estimated 104,700 of the critically endangered apes left as of 2012. The study also warns that another 45,000 orangutans are doomed by 2050 under the business-as-usual scenario, where forests are cleared for logging, palm oil, mining and pulpwood leases. Orangutans are also disappearing from intact forests, most likely being killed, the researchers say.
