| Outline and Purpose of the Course | Presentation of each research theme related (1) the production and maintenance of forest resources, (2) the preservation, regeneration and adaptation of environmental slope-related species, and (3) the sustainable and resilient forest management based on ecosystem approach; material cycling. Discussion and reviewing of related research papers/books are made by students, researchers and professors. | ||
| Course Goals | Understand the ecological characteristics of forest ecosystems and consider the appropriate use of such ecosystems. | ||
| Schedule and Contents |
1. Growth of trees and environmental factors (6 sessions) The sessions will consist of introductions and discussions of various research studies related to silviculture that focus on the relationship between the reproduction and growth of primary tree species in forests and environmental factors such as temperature, water, soil, and organisms. 2. Cycles of organic compounds and minerals in planted and natural forests (8 sessions) Organic compounds and minerals are discharged from forests through streams running through forests. When a forest is created artificially from a single species of trees, how does this circulation system change? We will introduce and discuss studies that compare planted forests and natural forests in order to examine the feasibility of redevelopment and maintenance of planted forests. 3. Renewal and maintenance mechanisms of natural forests and their stand dynamics (8 sessions) In a natural forest, lighting, moisture, snowfall, and other conditions vary depending on slope topography. Consequently, tree species vary from one location to another in a forest, and the mechanisms in which tree species are maintained are also different. The sessions will consist of discussions on these research topics. 4. Ecological conditions and management of planted forests and satoyama (6 sessions) Due to the neglect in management of planted forests and satoyama, their ecosystems have been deteriorating in recent years. Various projects are currently underway to manage the forests and revive them into forests that are rich in biodiversity. We will discuss research topics related to silviculture to examine new techniques and approaches. |

| Evaluation Methods and Policy | Evaluation will be based on an overall assessment of attendance, the content of presentation, and commitment to projects. | ||
| Course Requirements | Completion of Silviculture is desirable. | ||
| Study outside of Class (preparation and review) |
Go through the reference book and other relevant publications in advance. Students are encouraged to approach the course from a broad perspective as it will cover a wide range of topics, such as various characteristics of forest ecosystems and their applications. |
