This ancient mamane at Halepohaku has a trunk over two feet in diameter. It retains its old browse line from the days when tens of thousands of goats, sheep and cattle infested Mauna Kea, ravaging native plants. Mamane also look like this in ranch pastures, where cattle browse them and break their lower branches by using them as scratching posts. Most younger mamane near Halepohaku are now vaguely spherical, with leafy branches all the way down to ground level, because ungulates began avoiding the area after the namesake hunting cabins, and later the observatory dorms, were built.
