Table 1. Overview of study sites and reindeer in the early, mid and late summer season.

Period	Sites (n)	Reindeer (n)	Estimates of habitat selection (n)	Estimates of habitat selection per site (mean [range])
Early season	26	11	87	3.35 [1]–[10]
Mid season	67	8	224	3.34 [1]–[7]
Late season	51	6	73	1.43 [1]–[3]
Total season	144	11	384	2.67 [1]–[10]

Number of sites for estimates of phenology and cover of plant growth forms, the associated number of reindeer from which we attained tracking data and the number of attained estimates of habitat selection (number of 7-day periods of reindeer tracks overlapping with sites in time and space), in total and per site. All data are presented for early, mid or late season and for the overall summer season.
