Species and site characteristics used to fit dispersal models

This data file is a multi-tab spreadsheet that describes the characteristics of the 64 species and the 3372 50 x 50 km grid cells spanning the contiguous United States used in the spread models (where spatial data are calculated as the grid cell area-weighted average of county-level data used in Liebhold et al. (2013)). Within the spreadsheet, the 'griddata' tab includes scaled and unscaled spatial variables by grid cell, 'scaledhostden' includes scaled host density by grid cell, 'gridtreevolume' includes raw tree volume by grid cell as measured by the Forest Inventory and Analysis National Program (FIA), 'FIAcodes' lists the host FIA codes by pest species, and 'pestdata' includes scaled and unscaled pest characteristics.
