In the Sierra Nevada mountains of California, climate change is subtly eroding the health of pine and fir trees. The effect could be a portent of severe tree die-offs to come.

Ecologists have been tracking the fate of more than 21,000 individual trees since 1983 as part of a project to study forest ecology at different elevations in the Californian mountains. When Phillip van Mantgem and Nathan Stephenson of the US Geological Survey in Three Rivers, California, looked at the first 22 years of this record, they noticed that mortality rates of both pine and fir trees had increased at an average of 3% a year, nearly doubling overall (Ecology Letters, DOI: 10.1111/j.1461-0248.2007.01080.x). The increased death rates were seen at all but the highest elevations. Meanwhile, the rate at which new trees established did not change.

Hopes that planting trees could absorb significant amounts of carbon dioxide (CO2) and so help to sl
>ow down global warming look set to be dashed.

he Kyoto Protocol to halt climate change is based on a scientific fallacy, according to the first results of CarboEurope, a Europe-wide programme that has pioneered research into the carbon budget.

The protocol says that countries can help meet their targets for cutting emissions of greenhouse gases over the next decade by planting forests to soak up carbon dioxide. But the soil in these "Kyoto forests" will actually release more carbon than the growing trees absorb in the first 10 years, the new research shows.

"Countries will be able to claim carbon credits for the forests. But that won't reflect what is happening in the atmosphere," says Riccardo Valentini of the University of Tuscia in Viterbo, Italy. He presented the CarboEurope data last week in Valencia, Spain.

The project's revelations could embarrass governments now meeting in New Delhi to discuss implementation of the Kyoto Protocol. Earlier in October, Italy announced plans to achieve between 10 and 40 per cent of its emission reductions target for 2012 through forest planting. But now its own scientists are warning that these sinks might not work.

Global Initiative on Forests and Climate




How will it work?





The Australian Government is providing $200 million for ‘Global Initiative on Forests and Climate'. This funding will be used to support projects in selected developing countries (particularly, but not exclusively, in the South-East Asia and Pacific regions) to:






• build technical capacity to assess and monitor forest resources, and to develop national forest management plans;



• put in place effective regulatory and law enforcement arrangements to protect forests, including through preventing illegal logging;



• promote the sustainable use of forest resources and diversify the economic base of forest-dependent communities;



• support practical research into the drivers of deforestation;



• encourage reforestation of degraded forest areas;



• develop and deploy the technology and systems needed to help developing countries monitor and produce robust assessments of their forest resources;


• pilot approaches to providing real financial incentives to countries and communities to encourage sustainable use of forests and reduce destruction of forests.




These projects will be developed in cooperation with regional countries and relevant international organisations including the World Bank. They will reflect the priorities of the countries concerned, while seeking to achieve the maximum possible benefit for forest management and the global climate.




In relation to the provision of incentives to developing countries for sustainable forestry practices and reducing net forest loss, we expect to explore a range of approaches that reflect the differing needs and circumstances of different countries. However, a common element of any incentives is that they will be provided only on the achievement of pre-agreed forest sustainability milestones (e.g. agreed reductions in national deforestation rates). Measurement of achievement of these milestones will be underpinned by the investment in the technology and systems to robustly monitor forest resources.




Collaboration




Effectively tackling the issue of global deforestation will require a huge investment from governments and businesses around the world. The Australian Government will therefore be working closely with governments and businesses from other developed countries to build support for and help in the delivery of this global initiative, so that we can harness the collective effort required.





The contributions that other countries may make will obviously be a matter for them, but we will be talking to key countries about the initiative over the next few weeks. Those discussions will also address the most effective means for countries to mutually identify areas and projects for joint activity, and how best to form clusters of partners to undertake those activities.





As a soon as we have a good initial picture of the views of key countries and others, we will decide how best to proceed with this initiative, including through engaging key Ministers from these countries.





Planning and delivery of the Initiative in Australia will involve a whole of government effort, including through the Environment, Foreign Affairs (including AusAID) and Forestry Departments.

Working with both developed and developing countries the Australian Government's $200 million investment will:




• support new forest planting


• limit destruction of the world's remaining forests


• promote sustainable forest management


• encourage contributions from other countries.
