Trying to insure trees to fight warming

But there is wide disagreement on how to assess the risks under the new UN treaty, due to be agreed by end-2009. Forest owners want full access to credits as fast as possible.

"How much land managers will see of the price is what the excitement is about," said Frances Seymour, head of the Centre for International Forestry Research in Indonesia.
