Study design

 

Quasi-experimental design for assessing ecosystem impacts of contrasting reindeer densities among herding district in Finnmark: High density and low density districts are arranged in 10 pairs as to be able to apply a block-design in the analyses for partialling out the reindeer effect from the influence of other environmental factor

The contrasting reindeer densities among the 10 district pairs and the corresponding density-dependent calf weights in the same pairs
