像美国的许多地方一样，马里兰州正在迅速城市化。分散的低密度发展模式消耗了过多的土地，破坏了景观，取代了许多本地物种，破坏了生态系统的功能。马里兰州的绿色基础设施评估是马里兰州自然资源部（DNR）开发的一种工具，用于帮助确定和排名全州最具生态重要性的地区，以及那些发展损失风险最大的地区。它确定了大片相连的自然土地（枢纽），通过自然走廊相互连接，使动物和植物繁殖体扩散和迁移。枢纽和走廊在其自然地理区域内的各种生态和发展风险参数，以及这些组合的排名。还对生态重要性和发展脆弱性进行了更细规模（0.127公顷）的优先排序，从而可以更详细地分析网络内的站点优先级。通过绿色基础设施评估确定的枢纽和走廊框架正在用于指导马里兰州正在进行的土地保护工作。在多个州的范围内，绿色基础设施的方法已被用作框架内设置景观生态优先级的切萨皮克湾计划。在区域范围内，该方法已被用于国家土地保护计划的排名或重点地区。在地方政府的规划范围内，该方法目前正在转化为与当地相关的标准，以支持县一级的绿色基础设施举措。最后，基于单元格的排名方法已被纳入已被用来帮助国家，地方和私人土地信托保护决策的地块优先级。
Like many parts of the US, Maryland is urbanizing rapidly. The scattered pattern of low-density development consumes an excessive amount of land, fragments the landscape, displaces many native species, and disrupts ecosystem functions. Maryland's Green Infrastructure Assessment is a tool developed in the Maryland Department of Natural Resources (DNR) to help identify and rank those areas of greatest statewide ecological importance, as well as those at greatest risk of loss to development. It identifies large contiguous blocks of natural land (hubs), interconnected by natural corridors to allow animal and plant propagule dispersal and migration. Hubs and corridors were ranked within their physiographic region for a variety of ecological and development risk parameters, as well as combinations of these. Prioritization was also done on a finer scale (0.127ha) for ecological importance and vulnerability to development, allowing a more detailed analysis for site prioritization within the network. The hub and corridor framework identified through the Green Infrastructure Assessment is being used to guide Maryland's ongoing land conservation efforts. At a multi-state scale, the green infrastructure method has been used as the framework for setting landscape ecological priorities within the Chesapeake Bay program. At a regional scale, the method has been used to rank or focus areas for state land conservation programs. Within a local government planning context, the method is now being translated into locally relevant criteria to support county-scale green infrastructure initiatives. Finally, the cell-based ranking method has been incorporated into parcel prioritization that has been used to aid state, local and private land trust conservation decision-making.
