    17. 17. Modelling carbon in trees and forests A summary of the carbon exchange (in tonnes of carbon per hectare per year) associated with the main components of oak woodland (general yield class 6 m3 ha-1 yr-1) at the Straits Enclosure flux station in Hampshire. For comparison with the value for increment given here (4.0 tC ha-1 yr-1), a value of 3.8 tC ha-1 yr-1 was obtained for net ecosystem exchange in 2000 using eddy correlation. Note that the quantity of carbon added to the soil carbon stock on an annual basis is unknown and, if significant, would reduce the quantity of carbon lost through litter decay. Adapted from BROADMEADOW, M AND MATTHEWS, R.W.

    22. 22. Politics <ul><li>The FCTU have welcomed today's announcement by the Scottish Conservatives that they will oppose any proposals to lease out parts of the National Forest Estate to private investors and we now call on the Scottish Government to acknowledge the widespread opposition expressed through their own consultation and to withdraw the proposals without delay. </li></ul><ul><li>9 FEBRUARY 2009NEWS RELEASE No: 12178 </li></ul><ul><li>Woodland Creation &quot;must happen&quot; says Minister </li></ul><ul><li>Scotland must plant enough trees to cover a space 25 times the size of Edinburgh if it is to complete its vision of 25 per cent woodland cover by 2050. </li></ul><ul><li>Announcing a woodland expansion strategy paper today, Environment Minster Michael Russell said that an increase in woodland planting must happen and innovative proposals are needed to allow it to happen. </li></ul><ul><li>One option currently out for consultation is to lease some of the national forest estate to allow other companies to manage the forests. The income from this could generate around £200 million and would enable woodland creation rates to more than double to 10,000 hectares a year. </li></ul><ul><li>More trees will play a significant role in fighting climate change and providing many economic, social and other environmental benefits. Currently, around 10 million tonnes of CO2 are locked up by Scotland’s forests each year. If woodland creation rates can be doubled then there is scope for locking up an additional 4.4 million tonnes per year by 2050. </li></ul>
