Concerted programs to measure tree and ecosystem health may occur periodically in response to observed concerns. The development and continued refinement or aerial assessment technology using LIDAR or remote-sensing satellite data can make large-scale ecosystem health assessments far easier and more cost-effective than was formerly the case. 10.2 Using what you have gleaned from this and the previous section, briefly outline the key differences between sustainably managing native forests and plantations. 11HARVESTING TREES WHILE MINIMISING ENVIRONMENTAL IMPACTS The key environmental values that can be impacted by tree harvesting are: Soil structure and productivity Water quality and stream health Biodiversity conservation. In accordance with Federal and State Government legislation and associated regulations (eg Codes of Practice), sustainable forestry practices include harvesting native forests and plantations in a manner that avoids or minimises impacts to these values. The measures commonly used to minimise environmental impacts during tree harvesting operations are described in the following sub-sections: OPERATIONAL PLANNING AND MANAGEMENT Operational planning and management is a critical part of minimising the environmental impact of tree harvesting because it requires operational supervisors to identify the key environmental values and compels harvesting contractors to operate in ways that take account of them. Codes of Practice for forestry operations (or similar instruments) have been in force in all states and territories for many years now, including 27 years in Tasmania, and 25 years in Victoria. Although their format varies between states, they typically provide mandatory minimum standards,
