Human+Impacts

Human Impacts One human impact that occurs in the Petrified Forest are the trails there. The trails are both positive and negative. One reason why the trails there are important is because people who are not educated will know nothing about plants or petrified wood. On the trails, there are many different kinds of plants that I did not know about. The are signs on the trails to educate visitors there. I am positive that other people do not know about these plants either. This can help people become more educated and interested in plants or animals because there are unique kinds there. That is a positive and negative impact.

Another human impact are the ancient American Indians who moved there began generations of Indians. After the American Indians were there the Anasazi Indians followed by the Hohokam, the Sinaquan Indians arrived, who believed to be the ancestors of today's Hopi and Navajo Indian tribes that arrived one thousand years ago. More than six hundred and fifty ancient Indian sites exist in the park near the Puerco River. They affected the food system there. This was because they were the third level consumers. They not only disturbed the food chain there because of their large range of consumers, but also the environment. Nowadays, people have made the Petrified Forest into a visitation area. The Indians made the forest a positive impact for them but a negative impact for the animals and other organisms that live there.
