Michelle Osgood answering questions at the end of her talk. Schiedea haleakalensis currently grows only in nearly vertical cracks in highly cracked rocks. The two populations are on north-facing cliffs. Because of its late identification, it's not possible to know if it's always been rare and limited to north faces, or if it had broader distribution where it was subject to stress - such as feral ungulates, which were fenced out of the park in the 1980s. It's also a favorite of introduced slugs, which yes, have penetrated to altitudes of several thousand feet! Hand pollination of plants maintained in pots (some of them since 2004) has been very successful in producing seeds.
