2016 was not a great year for wildlife. Many species have been lost forever or been declared functionally extinct. Admittedly, many of them are lesser known species, which might explain why their demise was not plastered all over the news. They nonetheless represent another part of the global ecosystem being broken. A closer look at the established causes for extinction brings up some issues that have made the front page news more than once: Climate change, habitat loss and poaching are amongst the main causes.
Climate change has officially claimed its first victim in terms of killing off a mammal species. This dubious honour goes to the little known Bramble Cay melomys, a small rodent endemic to an island off the Great Barrier Reef. Rising water levels reduced habitat on the low-lying island.

The Extinction Countdown blog by John R. Platt in the Scientific American reports the functional extinction of the addax antelope (Addax nasomaculatus), which is native to the Sahara desert. Functional extinction means that the number of individual animals alive is too small to form a viable population for the future. In the case of the Addax, only three animals have been recorded in a 2016 survey. The decline of the addax is attributed largely to illegal poaching.
The Contomastix charrua lizard has been entered as officially extinct in the IUCN Red List in 2016. The site cites habitat loss due to human encroachment and disturbance resulting from tourism during the breeding season as the main contributing factors.
Climate change, illegal poaching and wildlife trade and habitat loss and disturbance due to humans encroaching on wilderness areas remain conservation challenges. Please consider helping in any way you can, from supporting your local wildlife initiatives, sharing information to increase global awareness and support or donating to conservation charities.
