Understanding management-induced changes in GHG budgets
There is a rich body of scientific literature regarding the effects of forest management on growth, productivity, and hence carbon sequestration. However, it is very difficult to derive general conclusions because the variation of site quality and the history of site development/disturbance events often obscure the differences in management-induced changes in carbon stocks.
The scale of any carbon assessment is crucial. Conclusions based on observations from spatially or temporally limited
Measuring and modelling management-induced changes in carbon storage
There are different sources of data for measuring carbon stocks: forest inventories, inventories of other variables (soils, vegetation, etc.), and plot/site level experimental data from intensive ecosystem research. However, the integration of different data sources/databases, and the harmonization across countries and approaches present an array of challenges.
Data are available at two different scales. Plot/site level data are key for the understanding of the underlying processes of carbon
The science-policy interface
The third focus of the workshop was to facilitate interaction between scientists and policy-makers related to the UNFCCC, KP, and specifically the questions concerning forest management activities under KP Article 3.4. Many scientists lack an understanding of terms and definitions relevant to the climate change policy process, particularly with respect to requirements for fulfilling country commitments under UNFCCC and the KP. During the workshop, policy experts who had directly participated in

2013, Journal of Environmental ManagementCitation Excerpt :We ran all the scenarios over 150 year simulation periods. Detecting management-induced changes in national forest ecosystem carbon balances requires a hybrid approach utilising inventories and models (Lindner et al., 2008). Changes in carbon stocks as a result of land use changes have usually been investigated by means of book-keeping models (Stevens and van Wesemael, 2008).
Are there any circumstances in which logging primary wet-eucalypt forest will not add to the global carbon burden?
2012, Agricultural and Forest MeteorologyCitation Excerpt :Generally, error margins and uncertainties are high in forest C accounting. Sources of error for particular C pools, and model aptness, have been described by numerous authors (e.g. Dean et al., 2004; Dean and Wardell-Johnson, 2010; Köhl et al., 2008; Lindner et al., 2008; Nabuurs et al., 2008; Seidl et al., 2008). Climate change itself produces another area of uncertainty, because increasingly, measurement of C flux and its forecast under forest management will have to compensate for the increasing background fluxes from climate change, e.g. the reversal of a growth trend across temperate and boreal Eurasia (Piao et al., 2011).
