Climate Resiliency - Carbon Sequestration (Midwest Conservation Blueprint 2026 Indicator)

Definition This indicator identifies the ability of lands and waters to function under changing climate conditions. It prioritizes areas based on the amount of above and belowground carbon stored. Pixels can take the following values: 1 – Lower carbon sequestration, not a natural asset 2 – Lower carbon sequestration, natural assets 3 – Medium carbon sequestration, not a natural asset 4 – Medium carbon sequestration, natural assets 5 – High carbon sequestration, not a natural asset 6 – High carbon sequestration, natural assets Selection This indicator was chosen as a targetable, important feature of the MLI goals that will be used to track conditions over time and prioritize areas for conservation. Indicators were defined through elicitation and prioritization exercises with federal and state participants. Criteria for the indicators includes 1) actionable, 2) measurable, 3) relevant to multiple groups across the region, and/or 4) representative of other social and/or environmental values. Input Data & Mapping Steps This indicator originates from the U.N. Environment Programme World Biomass and Soil Carbon data. To create this layer, MLI partners, members, and staff completed the following mapping steps: projected all input data to NAD83 (2011) UTM Zone 15N, resampled to a 30m raster, and reclassed the raster into the following 3 classes: 1 – 0-125 metric tons of Carbon per hectare, 3 – 126-205 mectric tons of Carbon per hectare, 5 – >205 metric tons of Carbon per hectare. Due to the low resolution of the data, we emphasized natural assets by mosaicking the Natural Assets layer to the Carbon raster. Finally, we removed highly altered areas from this layer using our Highly Altered Areas mask. For full mapping details, please refer to the Midwest Conservation Blueprint Development Process.

Environment Programme World Biomass and Soil Carbon data）。为生成该图层，MLI的合作伙伴、成员及工作人员完成了如下制图流程：将所有输入数据投影至北美大地基准1983（2011）通用横轴墨卡托15N带（NAD83 (2011) UTM Zone 15N），重采样至30米分辨率栅格（raster），并将栅格重分类为以下3类：1——每公顷碳储量0-125公吨，3——每公顷碳储量126-205公吨，5——每公顷碳储量＞205公吨。鉴于原始数据分辨率较低，我们通过将自然资产（natural assets）图层与碳储量栅格拼接，强化了自然资产的标识。最终，我们使用高度受干扰区域掩膜（mask）移除了本图层中的高度受干扰区域。如需完整制图细节，请参阅《中西部保护蓝图开发流程》（Midwest Conservation Blueprint Development Process）。如需下载所有蓝图输入与输出数据，请访问《2026年中西部保护蓝图数据下载页面》（Midwest Conservation Blueprint 2026 Data Download）。
