Federal lands in the United States have been identified as important areas where forests could be managed to enhance carbon storage and help mitigate climate change. However, there has been little work examining the context for decision making for carbon in a multiple-use public land environment, and how science can support decision making. This case study of the San Juan National Forest and the Bureau of Land Management Tres Rios Field Office in southwestern Colorado examines whether land managers in these offices have adequate tools, information, and management flexibility to practice effective carbon stewardship. To understand how carbon was distributed on the management landscape we added a newly developed carbon map for the SJNF-TRFO area based on Landsat TM texture information (Kelsey and Neff in Remote Sens 6:6407-6422. doi: 10.3390/rs6076407 , 2014). We estimate that only about 22 % of the aboveground carbon in the SJNF-TRFO is in areas designated for active management, whereas about 38 % is in areas with limited management opportunities, and 29 % is in areas where natural processes should dominate. To project the effects of forest management actions on carbon storage, staff of the SJNF are expected to use the Forest Vegetation Simulator (FVS) and extensions. While identifying FVS as the best tool generally available for this purpose, the users and developers we interviewed highlighted the limitations of applying an empirically based model over long time horizons. Future research to improve information on carbon storage should focus on locations and types of vegetation where carbon management is feasible and aligns with other management priorities.
美国的联邦土地已被确定为重要区域，在这些区域可以对森林进行管理，以增强碳储存并帮助缓解气候变化。然而，在多用途公共土地环境中，很少有工作研究碳决策的背景情况，以及科学如何支持决策制定。这项针对科罗拉多州西南部圣胡安国家森林和土地管理局特里奥斯河野外办公室的案例研究，考察了这些办公室的土地管理者是否拥有足够的工具、信息和管理灵活性来实施有效的碳管理。为了了解碳在管理区域内的分布情况，我们根据陆地卫星专题制图仪纹理信息（凯尔西和内夫，《遥感》6：6407 - 6422。doi：10.3390/rs6076407，2014），为圣胡安国家森林 - 特里奥斯河野外办公室区域添加了一幅新绘制的碳地图。我们估计，在圣胡安国家森林 - 特里奥斯河野外办公室区域，只有约22%的地上碳位于指定进行积极管理的区域，而约38%位于管理机会有限的区域，29%位于自然过程应占主导的区域。为了预测森林管理行动对碳储存的影响，圣胡安国家森林的工作人员预计将使用森林植被模拟器（FVS）及其扩展程序。虽然我们将FVS确定为一般可用于此目的的最佳工具，但我们采访的用户和开发者强调了在长时间范围内应用基于经验的模型的局限性。未来旨在改善碳储存信息的研究应聚焦于碳管理可行且与其他管理优先事项相一致的植被位置和类型。
