Welcome to the Indicator Species List page of the Ocean Alliance Project. Here, you can find comprehensive lists of key indicator species that are crucial for monitoring the health of Hawaii’s marine ecosystems. These species serve as vital signs of the overall condition and changes within our coral reefs and marine habitats.
What Are Indicator Species?
Indicator species are organisms whose presence, absence, or abundance reflects specific environmental conditions. By monitoring these species, we can gain insights into the health and stability of marine ecosystems, detect early signs of stress or degradation, and inform conservation efforts.


Explore Our Indicator Species Lists
We have categorized our indicator species into two main groups to help streamline your monitoring and reporting efforts:
- Invertebrate Indicators: Discover the essential invertebrate species that signal reef health and environmental changes. View Invertebrate Indicators
- Chordate Indicators: Explore the key chordate species, including fish and other marine vertebrates, that provide critical information about ecosystem dynamics. View Chordate Indicators
Why Indicator Species Matter
Monitoring indicator species helps us:
- Assess Ecosystem Health: Understand the current state and trends in biodiversity.
- Detect Environmental Changes: Identify early signs of stress, pollution, or habitat degradation.
- Guide Conservation Efforts: Inform and prioritize conservation actions and policies.
Thank you for contributing to the Ocean Alliance Project’s mission to protect and preserve Hawaii’s marine biodiversity. Your involvement is essential in safeguarding our oceans for future generations.
