Abstract: Effects of an extreme drought were examined along an elevational
gradient on Mauna Loa Volcano, Hawai'i. The composition, vigor, and
survivorship of plants were examined on a 2400-yr-old pahoehoe lava flow at
three elevations: 1755,2000, and 2195 m above sea level. Three plant species,
Coprosma ernodeoides A. Gray, Styphelia tameiameiae (Cham. & ScWechtend.)
F. v. Muell., and Vaccinium reticulatum Sm., were encountered most frequently
at the three sites. Greatest mortality occurred at the site at 2000 m elevation,
where the drought caused a shift from a slight excess of precipitation over
evaporation to a large excess of evaporation. Occasional severe droughts may
play an important part in shaping primary succession in this region.
