The mountain gorilla and the fin whale have been reassessed and their conservation status had been found to not accurately show their position.
In the case of mountain gorillas, this is understandable. In 2008 the mountain gorilla population numbered approximately 680, the most recent number was around 1000. That is an increase of roughly 50% in just a decade. As such they have been moved from critically endangered to endangered. Mountain gorillas are only found in two reserves and so the population will always be delicate, but clearly for the time being, with less instability in the region they are doing well. Given the wars and issues of this region, though, this position could change very fast.
