Impact of tourism on habitat use of black grouse (Tetrao tetrix) in an isolated population in northern Germany
Fig 5
Adaptation of black grouse habitat use to human presence by time of day.
Boxplots show distance distributions towards public routes in the course of the day (left-hand ordinate). Curves show occurrence of hikers on three trails closest to the home ranges (right-hand ordinate). Graphs are shown separately for sites and sexes. Telemetry and human activity data were collected in different monitoring periods. The comparison of both data sets is based on the assumption of constant visitor flows.
