I chose the article ‘Production Ecology and Reverse Growth of Ponderosa Pine’ by Ezequiel Fernández-Tschieder, Dan Binkley, William Bauerle. I believe this is a peer reviewed research academic article. It is written by experts in the field, you can see their credentials underneath their names in the article. The article also includes in text citations and a bibliography. It is peer reviewed because it was produced in 2019 but then revised in 2020, which I believe means it was reviewed. The article contains a methods sections and a results sections, making it a research paper.
