The east slope of Mauna Kea right mauka of Hakalau Forest is pretty much gorse, gorse, and more gorse. As far as the treeline. A nasty invasive shrub from Europe that threatens native lanscapes in Hawaii and many other areas around the world. Real bugger to hike through!
Tetragnatha species seen in Hakalau forest, ID'd by Rosemary Gillespie as very probably quasimodo.
