The regional ecological significance datalayer developed in 2010 emphasized the importance of functional landscape patches of semi-natural and natural vegetation, and the results are most appropriate for use when setting priorities on a regional scale. Many project-based decisions must be made at a finer scale of resolution. We developed a project-level ecological significance datalayer to address this need. The spatial grain size of the project-level significance datalayer is greater than that of the regional significance data. Scores are applied to all mapped current vegetation types (community types) to define project-level significance, whereas regional significance was mapped based on patches of natural and semi-natural vegetation made up of several or many individual mapped vegetation types that were combined or collapsed together. Nonetheless, many of the same input datalayers generated for regional ecological significance evaluation were used to generate project-level significance, including current land cover and community importance ranking, rare species locations and status, public lands, and the final results of the regional analysis itself. Data development details are found in "Ecological Approach to Infrastructure Development for the East-West Gateway, Final Report," available from the East-West Gateway or from the MoRAP website (http://www.cerc.usgs.gov/morap/Assets/UploadedFiles/Projects/EastWestGateway/Regional%20Ecological%20Significance%20Data%20Layer%20Report.pdf). brief narrative summary of the content of the resource(s)
