Broad-scale analysis of greater sage-grouse population trends in response to grazing records in Wyoming, USA (2004-2014)

The file 'ssm_data.csv' contains data necessary for analyzing state-space models for male greater sage-grouse (Centrocercus urophasianus) populations in response to grazing level (relative grazing index), timing, and NDVI (Normalized Difference Vegetation Index) in Wyoming, USA, and then to compare models with 10-fold cross validation scores (Monroe et al. 2017).
