This module develops an understanding of the principles and practice of silviculture, the place of silviculture in the sustainable cultivation of trees, and the role that silviculture plays in delivering ecosystem services from trees, woodlands and forests.

We explore the unique characteristics of forest soils and of soil physical, chemical and biological properties, how these influence site productivity and how these are influenced by land management.

The module begins with a brief review of the history of silviculture and its role in the sustainable management of tree, woodland and forest resources. We will look at some of the basic botany of tree growth, and consider the role that genetics plays in shaping species’ silvicultural characteristics and responses to silvicultural interventions. Productivity is to a large extent driven by environmental conditions, particularly the edaphic (soil) environment, and we will look at how these site conditions influence the choice of species to plant. Two units will focus on silvicultural practices from regeneration through to harvesting (or should that be from harvesting through to regeneration?) considering a range of examples from temperate and tropic regions. We will look at a range of silvicultural systems, historic, current and future, again considering how the choice of system is influenced by the local environmental context as well as by management objectives. In the final unit, we will consider ways in which we might use all the above knowledge to transform woodlands or forests, bringing them into productive management, or restoring them to a desired state.

threshold

• show a basic understanding of the variation in silvicultural characteristics among and within species and the physical, chemical and biological properties of soils and explain why these are important when matching species to site.
• be able to describe the silvicultural practices used in trees, woodlands and forests, and to explain why and where they are used currently. • be able to describe a variety of silvicultural systems and explain why and where they are used currently.
• be able to identify basic silvicultural actions for achieving a set management objective and delivering a specific ecosystem service.

1. Show a critical understanding of among and within-species variation in silvicultural characteristics, the physical, chemical and biological properties of soils, and the relevance of these to the process of matching species to site.

2. Discuss in detail a variety silvicultural practices and evaluate their suitability and effectiveness in managing trees, woodlands and forests for different objectives.

3. Discuss the concept of silvicultural systems, and evaluate the use and relative merits of a variety of silvicultural systems.

4. Identify specific silvicultural actions for achieving management objectives and delivering ecosystem services from specific tree, woodland or forest situations now and in the future.
