Cultural Landscapes Inventory
The Cultural Landscapes Inventory (CLI) is a comprehensive inventory of all culturally and historically significant landscapes within the National Park System. The CLI records each landscape's location, historical development, existing conditions, and management information. For landscapes found to be potentially eligible for the National Register of Historic Places, the CLI provides an analysis of landscape characteristics and features, allowing for an evaluation of historic integrity and significance. The information is used at the national and regional level to inform planning efforts and budget decisions. On an individual park level, the CLI provides park managers with a vast array of information specific to the landscape of their park.
Coordinated at the regional level, the CLI will include entries for all national parks within the system. In the northeast region, the CLI is maintained by the Olmsted Center, where the highest priority for all cultural resource inventory work is given to parks starting a new or updated general management plan (GMP). Parks that have proposed development and construction projects, lack baseline information, or are the focus of ongoing cultural landscape reports are included on the priority list, which is updated regularly as landscapes are inventoried and as regional priorities change.
Historical landscape architects gather data for the CLI from existing secondary sources found in park libraries and archives, as well as through on-site reconnaissance of the existing landscape. Each completed inventory is stored in the national CLI database in Washington D.C., and in the regional database at the Olmsted Center. The CLI is accessible to the National Park Service through an intranet web site.
