A paper detailing results of the study, recently published in the journal Ursus, reported that while Andean bears didn't show a particular preference for tree-rubbing species, the locations of rubbed trees and shrubs were concentrated on trails near water holes. In the tropical dry forests of Peru, water is a relatively rare, albeit critical resource. Consequently, since livestock in the area also make use of water resources, conflicts may result between humans and bears.

This study is part of a larger effort by San Diego Zoo Global researchers and local partners to better understand Andean bear behavior and ecology. Andean bears are considered an umbrella species in the region, meaning that conservation programs aimed at protecting Andean bears will indirectly benefit other species in the Andes Mountains.
