A forest science program provides important knowledge regarding the value of forests and how these areas are pivotal to global ecosystems. Individuals who study forest sciences learn about the growth and development of forests, the climatology of woodlands and factors that influence the health of forests.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.
