I left out this short summary. I really hope you can check this, too. Thank you.
1) Elephants are afraid of coming up close and personal (a synonym?) with humans because they have always been heavily poached.
2) The author of the article writes that he worked on a conservation programme concerning elephants. So, they needed elephants to trust them.
First, they built their camp near the Marula trees because those trees offered lush shadow in the hot season. 3) However, they realized that their camp stood in the way of an elephant’s family, who had probably been coming to eat the fruits for many generations.
4) At first the elephant stood on the edge of the camp and he didn’t risk coming any further.
5) After twenty minutes (or twenty minutes afterwards) he finally dared to walk quickly into the camp and began feeding on the fruits.
6) Though the other elephants were afraid of coming close to humans, little by little this elephant learned to trust them. As he represented hope for all elephants, they decided to name him Survivor.
1. ... afraid of coming close to humans because ...
2. delete the comma after "So" and join the two sentences into a compound sentence, with a comma after "elephants"
3. "fruit" is better than "fruits" (I don't know why, just reads more smoothly.)
4. two commas needed
5 and 6 are fine; delete words in parentheses
