Introduction to Korean pine: Fenglin Nature Reserve preserves the most typical and complete original Korean pine forest in my country, accounting for 78.4% of the entire forest. The broad-leaved Korean pine forest ecosystem is the result of long-term historical development and natural evolution. It records historical changes and accidents, provides evaluation criteria for measuring the impact of human activities on the environment, and also provides guidance for international research on boreal forest biodiversity. Provides an ideal location and original "background" information.
