Abstract
In Scotland, the geographical distribution of red deer (Cervus elaphus scoticus) overlaps with
areas used for popular outdoor activities such as hill walking. This overlap can have multiple
consequences for the animal but also for its successful management. Here, I study the impact of
hiking activity on red deer spatio-temporal distribution, behaviour, and interaction with sheep.
First, to study the impact of hiker activity on deer detection and on their behaviour, camera
traps were placed in transects at different distances (25, 75 and 150m) from the hiking path.
Hiking activity was monitored and classified as busy or quiet. Second, to study how hiking
activity influenced red deer interaction with sheep, camera traps were distributed at various
distances from the hiking path. I found that red deer spatial and temporal response occurred at
less than 150m, as more red deer were detected at 150m than at 25m. During the day, red deer
were detected at greater rates in an isolated area relative to areas close to the hiking path. This
avoidance only occurred on a short temporal scale, as deer returned to areas close to the hiking
path the following night. I did not detect an increase in vigilance or flight behaviour closer to
the hiking path or during busy hiking activity. However, the interaction between sheep and deer
changed with distance from the hiking path, with greater spatial and temporal overlap in areas
further away from the hiking path. I conclude that (i) hikers impact the spatial distribution of
red deer at distances smaller than 150m but that this impact is only of short duration temporal
scale, (ii) hiking activity does not have a significant impact on the behaviour of the animal, and
(iii) hiking activity may influence the interaction between sheep and deer.
