As Clark finished reading the journal entries and pushing himself back to other pages to get a better understanding, he developed a respect. The researchers that had gone in to the violent jungle had named it this only for the fact that those that did not travel with care would perish violently.
The plants were very dangerous. Many plants or plant type beasts lived in this area. They would do whatever they could to survive, some developed poisons over time while others became more sentient and hunted for prey. Both were extremely deadly in their own ways.
What struck Clark as odd was that the researchers still called this place violent even though it was just the way nature was. Nature was both peaceful and violent. The reason that the quests he had received was a question wasn't because the jungle was truly violent in the deep wilderness. It was because Clark had to make the end decision if he would see all wilderness as violent.
