While the iconic Haleakal silversword plant made a strong recovery from early 20th century threats, it has now entered a period of substantial climate-related decline. New research published this week warns that global warming may have severe consequences for the silversword in its native habitat.
The Haleakal silversword (Argyroxyphium sandwicense macrocephalum) grows only on a single volcano summit in Hawaii, yet it is viewed by 12 million visitors annually at Haleakal National Park.
