USGS Pacific Island Ecosystems Research Center – Community-Level Response to Change in Hawai‘i
Resource Title: Community-Level Response to Change | U.S. Geological Survey
Organization: United States Geological Survey
Description:

This USGS PIERC portal highlights ongoing research on how Hawaiian ecosystems—especially forests and plant communities—are responding at the community level to environmental shifts. Focus areas include climatic changes (e.g., drying trends, elevated temperatures), invasive species dynamics, and innovative monitoring approaches like plant physiology measures and environmental DNA (eDNA). There are strong links to climate-informed conservation strategies in Hawaiʻi.

Target Audience: Educators, Facilitators, High School, College
Instructional Roles: Enrichment
Environment: Online only (e.g. interactive map), Self-guided
Content Type: STEM investigation
Type Of Engagement: Investigate, Observe, Reflect
Format: Webpage
Activity:
  1. Water-Stress & Plant Growth Monitoring

    • Using methods from PIERC’s plant physiologic response project, students can monitor stem growth or leaf water potential of native species (e.g., ʻōhiʻa) alongside local weather data.

    • Hypothesize how changes in moisture or temperature might affect plant community health.

  2. eDNA Community Snapshot

    • Collect soil or water samples from a native forest in Hawaiʻi (e.g., Hakalau, Waimea) and send to a lab (or classroom micro-lab) for eDNA analysis.

    • Compare baseline biodiversity to documented native/invasive presence and discuss monitoring advantages of eDNA.

  3. Modeling Future Vegetation Change

    • Introduce students to PIERC’s mapping of plant shifts from tools like satellite imagery (e.g., Lāna‘i study).

    • Have learners interpret before-and-after vegetation maps or create simple models predicting native/non-native composition under projected warming scenarios/

  4. Species Vulnerability Case Study

    • Assign research on species at risk from changing temperature regimes—like montane plants or forest birds (e.g., Hawaiian forest birds restricted by malaria limits).

    • Develop adaptation strategies such as microrefugia, assisted migrations, or predator/invasive control actions.

  5. Stakeholder Science Fair

    • Reflecting PIERC’s collaborative approach, students design “research pitches” combining community data, climate projections, and monitoring tools.

    • Present to local stakeholders (DLNR, DOFAW, watershed groups), simulating how science informs land and forest management.

Topics Covered:
  • Community-level ecological responses to climate change and drought in Hawaiʻi

  • Plant physiological measurements and growth monitoring

  • Cutting-edge biodiversity monitoring: environmental DNA methods

  • Remote sensing and spatial modeling of vegetation change (e.g., Lāna‘i mapping)

  • Vulnerability assessments and adaptation strategies for native Hawaiian flora and fauna

  • Science–management integration: informing real-world conservation practices
