n Puna, the area of Hawaii island that’s been hardest hit by the Kilauea volcano eruption, those who lived nearest to the lava flows watched the forest around their homes begin to die first. They said the fruit trees, flowers and ferns began turning brown, languishing in the noxious, sulfur-dioxide-filled air. Then the lava came. Now large swaths of formerly verdant forest has been replaced by rough and barren volcanic terrain. “Before the eruptions, that area was probably the best forest left in the state of Hawaii,” said Patrick Hart, a biology professor at the University of Hawaii at Hilo. “There were areas where the native Ohia forest extended right up to the ocean, and you just don’t see that in the rest of Hawaii,” he said. Now it’s covered with 20 to 30ft of lava. On Hawaii island, also known as the Big Island, lava from the weeks-long eruption of the Kilauea volcano has also paved over tide pools and coral gardens, boiled a 400-year-old lake until it evaporated and killed a number of sea creatures. But to scientists, it’s just part of life on the state’s youngest island, where land is still being created as lava continuously reshapes the natural environment. “From a human point of view, what’s happening is tragic,” said David Damby, a volcanologist with the United States Geological Survey (USGS). “But from the volcano’s point of view, that’s the job she does: to build new land and change the landscape. That’s the way the earth works.” The humid, rainy forests in Puna were an important habitat for native Hawaiian trees, birds and insects, Hart said. Chartreuse-colored ‘amakihis and bright red ‘apapanes rested on trees, Hawaiian hawks soared through the air, and dragonflies, butterflies and crickets all made the forest their home.
