At SCE our volunteers learn all kinds of neat bush skills. Like when we found this tree with mud on one side. Animals like elephants, rhinos and warthogs cover themselves with mud or sand, especially after swimming. This acts as a useful substance to help dislodge ticks when they rubs themselves on rocks and trees. One can guess which animal rubbed on a tree by looking at the height of the mud mark (high mark possibly being an elephant or rhino and lower could be a warthog) and also by looking at foot prints or any fresh dung around the area.
