Study: Drought threatens rare silversword plants at Haleakalā NP

Though the population of rare nēnē, aka the Hawaiian goose, is growing in Hawaii, the outlook for the equally rare silversword plants at Haleakalā National Park in the Aloha State is not as promising due to drought.

The nēnē, which long had been listed as endangered under the Endangered Species Act, earlier this week was downlisted to threatened due to the conservation efforts that have enabled the geese to grow their numbers from as few as 50 back in the 1970s to more than 3,000 today. However, the same optimism does not currently surround the silversword.
