Note: My National Geographic magazine entries are NOT in order. (This is because I don't always have time to do my entries
Hi! I dinosaurs. Today i will be doing a 2016 (May) National Geographic magazine entry. This is part two on Yellowstone. Let's begin!
COMEBACK OF ANIMALS IN YELLOWSTONE: In my last summary, I talked about how tourism affects wildlife in Yellowstone. And in my last summary, I also talked about that despite tourism, animals in Yellowstone might not be going extinct.
In this summary, I will talk about how animals in Yellowstone have came back from endangered or even extinct in Yellowstone to balanced numbers of animals.
Animals in Yellowstone have faced hard times indeed.
For example, wolves: From 1927-1995, 0 wolves roamed the Greater Yellowstone Ecosystem.
Then from 1995-1997, 41 wolves were reintroduced to Greater Yellowstone by humans.
In 2014, at lease 510 wolves roamed Greater Yellowstone.
Next up: Brown bears.
In August 1967, all the Yellowstone dumps closed. Because of the shutdown of the garbage buffet, brown bears got hungry, made mistakes, got hunted and there reproductive rate fell.
Brown bears in Yellowstone, though were, in 1975, were listed by the Endangered Species Act.
Hunting of Brown bears in Yellowstone stopped - at least for the people who followed the law.
Instead, humans followed practical measures, like patrolling campgrounds and not leaving food around overnight.
Then, bear managers taught the bears to eat natural foods.
Soon brown bear numbers in Yellowstone increased quickly.
Even trees have nearly went extinct.
It is a kind of tree called the Whitebark pine tree. Mountain beetles take nutrients from the tree, and the tree dies.
Super cold weather can kill these beetles, but this kind of weather is now rare because of climate change.
To this day, Whitebark pine trees in Yellowstone die - quickly.
Conclusion: I conclude that while some animals in Yellowstone are safe, others aren't. We need to protect the animals that are not safe, instead of making there problems bigger.
