Ecosystem Function and Services

Land managers require clear, forward-looking information about where and how vegetation treatments may make the greatest difference for drought resilience in sagebrush and woodland ecosystems. We are using soil moisture and vegetation data from SageSTEP-- a long-term ecological study on fuel treatments in the Great Basin-- to analyze soil moisture dynamics and vegetation responses after common...

We are studying post-fire forest regeneration in montane habitats within Hawaiʻi Volcanoes National Park. By testing out different restoration strategies, as well as links between grass cover and fire, we hope to increase restored forest fire resistance and resilience.

The Elwha River – located on the Olympic Peninsula in Washington - is home to an iconic dam removal and ecosystem restoration project. The Elwha offers a unique setting to explore the ecosystem level effects of dam removal and river restoration because of its prominence, such as large sediment volume, several salmon populations, and pristine wilderness.

We are working on understanding the chemical ecology of Rapid ʽŌhiʽa Death - ROD -, which is critical for protecting both healthy and ROD-infected ʽōhi‘a. A better understanding could lead to early ROD detection tools and the development of attractants and repellents to manipulate ambrosia beetle populations.

To document movement patterns and habitat use of Hawiian Hawks, GPS tags were attached to 17 individuals to track their movement across continuous, fragmented, and urban landscapes. We are now gathering multi-year tracking data to assess key aspects of habitat needs, and how these birds navigate through different ecosystems.
