Projected Species Range Maps over the Next Century

Hawaiʻi Volcanoes National Park is home to 23 species of endangered vascular plants and 15 species of endangered trees. Understanding how climate change may impact the park’s plants is vital for their long-term survival. This product was designed to assist managers of Hawaiʻi Volcanoes National Park in preparing for a changing climate by identifying how plant distributions within the park may shift under future climate conditions, focusing on how these distributions compare with currently defined Special Ecological Areas within the park.

Sea Level Forecasts

While global sea-level rise concerns many Pacific Island communities, local sea levels are affected by many factors, including basin-wide phenomena like the El Niño-Southern Oscillation (ENSO), making for higher or even lower water levels. This online tool provides an outlook of monthly sea level anomalies for the next one to two seasons (out to six months), combining sea level forecasts with astronomical tide predictions to provide more accurate predictions of coastal water level compared to tide predictions alone. Such forecasts may enable decision makers and local resource managers to prepare for unusual water levels, both high and low, in their areas.
