3.6 Giant panda mark types and orientations
We recorded the type of marks used for scent marking in pandas and the
orientation of the marks. The most frequently found marker was the AGS
mark, which contained 144 of the 157 scent marked trees, accounting for
91.7% of all marked trees. The least frequent mark was Scratch mark,
which contained 4 out of 157 scent marked trees, accounting for 2.5% of
all marked trees, and Scratch mark was always accompanied by AGS mark
(Figure S2). The most marker orientation is face to trail, which
contains 128 out of 157 scent marked trees, accounting for 81.5%, while
the least mark orientation is back to trail, with 6 trees, accounting
for 3.8%, and multiple directional marks were accompanied with face to
trail mark (Figure S3).
