Density of Line Features in the Western United States Density of linear features, such as roads, power lines, telephone lines, and railroad tracks have been shown to influence synanthropic predator abundance patterns (Knight et al. 1995). Following Knight et al. (1995), we used linear features such as roads, railroads, and power line spatial data sets, but also included irrigation canals, to build a linear features spatial data set. However, we lacked spatial data on telephone and feeder-power lines and therefore our linear feature spatial data set vastly underestimates the number of linear features in some areas.

Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was avaliable as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTATION OF THE SUM TOTAL OF ALL POWERLINES ON THE GROUND. These data primarily depict the higher voltage, long distance transmission lines but some arcs likely represent lower voltage distribution lines.
