Citizen Forester Tree Species ID Guide – Hawaiʻi (2021)
Resource Title: Citizen Forester Tree Species ID Guide – Hawaiʻi (2021) | Division of Forestry and Wildlife
Organization: Department of Land and Natural Resources
Description:

This downloadable guide from DLNR’s Kaulunani Urban & Community Forestry Program is designed for citizen foresters across Hawaiʻi. It provides identification characteristics, ecological roles, and planting advice for native and non-native trees found in Hawaiian urban and community settings—covering species from ʻōhiʻa and koa to ironwood and coconut palm.

Target Audience: All
Instructional Roles: Assessment, Enrichment, Hook activity, Main lesson, Ongoing activity
Environment: Field trip, Self-guided
Content Type: STEM investigation
Type Of Engagement: Investigate, Observe, Reflect
Format: PDF Guide
Activity:
  • ʻŌhiʻa Health Monitoring Project

    • Using the ID guide, students identify ʻōhiʻa (Metrosideros polymorpha) on campus or in their ʻāina.

    • Monitor trees monthly for signs of Rapid ‘Ōhiʻa Death (ROD), and record measurements and tree health data.

  • Tree Canopy Mapping Assignment

    • In small groups, map tree species using the guide in places like schoolyards or neighborhood parks.

    • Use the Kaulunani-provided TreePlotter tool to calculate canopy cover and list species, categorizing them as native or non-native.

  • Native vs. Non-Native Case Study

    • Students select two species—for example, native koa vs. invasive ironwood—and research their ecological impacts, economic value, and cultural significance in Hawaiʻi.

    • Present findings via posters or interactive slides.

  • Planting the Right Tree Workshop

    • Build a lesson around DLNR/HECO’s “Planting the Right Tree in the Right Place” practices.

    • Students choose appropriate tree species for different Hawaiʻi landscapes (coastal, lowland, upland) and justify choices based on ecological and cultural values.

  • Citizen Forester Field Training Simulation

    • Simulate a Kaulunani training: train students to measure trunk diameter, assess tree condition, and enter data, mirroring state-certified citizen forester protocols

Topics Covered:
  • Urban/community forestry in Hawaiʻi & canopy management

  • Tree species identification and classification

  • Ecological value: carbon sequestration, air-quality, shade, watershed protection

  • Threats to forest health: invasive species, ROD, droughts

  • Cultural significance: ʻŌhiʻa, koa, māmane, kōlea

  • Citizen science skills: inventory mapping, data collection, monitoring
