The threatened Haleakalā silversword
Publication summary: 

The threatened Haleakalā silversword is endemic to high elevations on Haleakalā volcano on the Island of Maui, and is one of Hawaiʻi’s most recognizable species. Silversword population, which is strongly positively correlated with rainfall, is estimated to have declined approximately 60% since the early 1990s. The reversal in the silversword population trajectory and declines in rainfall in silversword habitat coincide with an abrupt increase in the frequency of occurrence of the trade wind inversion (TWI) in Hawaiʻi around 1990.
