The number of reindeer deemed lost due to carnivores are closely related to population sizes of reindeer. This may be due to a numerical response of the predator, i.e. the predator kills more reindeer when more reindeer is available. Increasing population size of reindeer may also lead to food limitation and increased compensatory mortality. Knowledge of the population sizes of reindeer is crucial to understand the magnitude and ultimate causes of losses that are deemed due to carnivores. Below you may examine temporal trends in reindeer number, or download the data for further analyses.
