Hello friend, I love the subject of your publication have a time law information on these gorillas, from Grauer vary between 600 and 2900 m asl in dense tropical rainforests and secondary lowland forests through transitional forests Afromontane habitat, which They include bamboo forests, swamps and peat bogs. Mountain gorillas are restricted to elevations above 1,100 m.
For the date of 2013 and 2016 an estimated calculation was made, it is likely that there are less than 5,000 gorillas from the east. The most recent estimate for Mountain Gorillas is 880 individuals living in two isolated populations in the Democratic Republic of the Congo, Rwanda and Uganda. I think you are quite right in your esteem for these times friend.
Thanks for the additional info :) I'm glad you liked my post.
