What is Sustainable Forest Management?
Sustainable forest management (SFM) refers to the management of our private and public forests to ensure they continue to provide not only a sound supply of renewable timber for present and future generations, but also maintain their environmental values and social services.
SFM is dependent on credible science and professional commitment to improving the nature of forest management by responsible agencies and forest managers. In Australia, governments set policies and targets to guide the application of sustainable forestry, particularly on public land.
Nationally we have adopted principles and measures that are based on international level criteria widely agreed among nations with strong, long-term forestry industries. Some of the criteria for SFM are;
- conservation of biological diversity.
- maintenance of productive capacity of forest ecosystems and their health and vitality.
- conservation and maintenance of soil and water resources.
- maintenance of forest contribution to global carbon cycles.
- maintenance and enhancement of long term multiple socio-economic benefits to meet needs of societies.
State forest and land management agencies and corporate forestry organisations often use the term ESFM – i.e. ecologically sustainable forest management, to describe the approach outlined above. A reputable forest and environmental consultant recently proclaimed, “The language of sustainability is now being spoken from the boardroom to the bush”, suggesting that the message of SFM is now widely accepted.
In summary, ESFM is aimed at achieving a continuing balance of timber supply, economic and social benefits, while retaining a range of environmental values.
Some contrasting realities that Australians should consider in the sustainable management of our forests include:
- Our indigenous communities had, and some still have, a wealth of awareness and knowledge on how to look after woodlands and forests in a sustained way for a variety of values. Aboriginal people lived in balance with their wooded environment, drawing on only as many resources as it would sustain, for thousands of years.
- In parts of Asia-Pacific countries to our north, and on the South America and African continents, forests are still being cut down without proper management to ensure their regeneration, sometimes illegally. They are not regarded as being sustainably managed and natural forest resources are being greatly diminished and in some cases continue to decline.
Fortunately, in an affluent country such as Australia, forest management is highly evolved and our forest scientists and practitioners are constantly striving to improve and apply sustainable forestry practices.
Sustainable Yield
In relation to native forests, sustainable yield is a technical term which relates to harvesting timber where the volume of wood removed from a forest each year must at least be equalled by the forest’s renewal of itself through natural regeneration and growth of trees in unharvested areas.
Determining what the level of sustained yield is, and then monitoring and potentially altering it over time, is a complex matter. Usually it is expressed in tonnes or cubic metres of logs taken annually from a defined forest area. Predicting what a forest can sustain over 10, 20 and 30 year periods, and beyond, is subject to considerable uncertainty due to the impact on growth of changing rainfall patterns, wildfire and disease, the potential need for additional conservation reserves, community demands or other scientific reasons.
Forest managers have become skilled in sustained yield determinations and have many tools with which to validate predictions and monitor progress over time.

Earth Alive by Planet ArkEarth Alive is a 10 week actionbased science unit of work suitable for students in Years 5 & 6 focusing on authentic scientific investigation resulting in local action. The program investigates biodiversity in the school grounds and culminates in a Schools Tree Day planting action project. |

2. Multi Media task: Value adding to woodWhen trees are harvested, the various parts of the tree are graded for different end uses as seen in this 'Going Bush' series video on value adding. Technological advances have helped mechanise harvesting and processing operations. Tree replanting is conducted after harvest to assist with forest regeneration. Forest Ecologists are the scientists that help with identifying rare and endgangered species to ensure areas of forest remain for habitat protection. |
