Quantitative Analysis of Terrain Ruggedness in Reindeer Winter Grounds

We report a distinct terrain structure in high-use portions of reindeer (Rangifer tarandus tarandus) winter grounds for two regions within Norway. A new index of terrain ruggedness based on topographic maps was used for analyzing terrain structure within historic high- and low-use portions of winter...
