Lesson 2: Biodiversity & Endemism in Aotearoa
Learning Intention: We Are Learning To understand why New Zealand has unique species and what threatens biodiversity.
Success Criteria: I can explain endemism, identify threats to native species, and propose conservation solutions.
Starter (15 mins)
Tuatara Time Machine
Show students images of tuatara alongside their ancient relatives and dinosaurs. Ask: "Why does New Zealand have a 'living dinosaur' when nowhere else does?" Introduce the concept of geographic isolation leading to unique evolution.
Key Question: What makes New Zealand's wildlife special compared to Australia or other countries?
Main Activity 1 (20 mins)
Endemic Species Investigation
Students work in pairs using the "Endemic Species Detective" handout to research NZ endemic species. Each pair gets assigned a different species (kiwi, kakapo, tuatara, kokako, giant weta, etc.).
Tasks:
- Research their species' unique adaptations
- Find out why it evolved only in NZ
- Identify current population status and threats
- Discover any mātauranga Māori connections
Digital Activity (15 mins)
NZ Biodiversity Challenge Game
Students use the interactive "Biodiversity Tagger" game to identify native vs introduced species in different NZ habitats. The game shows photos and students must quickly categorize each species.
Extension: Advanced students can create their own habitat biodiversity comparison using data from different regions.
Launch GameMain Activity 2 (15 mins)
Species Gallery Walk & Māori Connections
Each pair presents their endemic species research to the class in a gallery walk format. Focus on sharing:
- What makes their species unique
- Traditional Māori knowledge about the species
- Current conservation status
- Biggest threats facing the species
Cultural Connection: Discuss how whakapapa (genealogical connections) applies to endemic species - they are truly "children of the land."
Plenary (10 mins)
Biodiversity Threat Analysis
As a class, create a mind map of threats to NZ biodiversity on the whiteboard:
- Introduced species: possums, stoats, rats, cats
- Habitat loss: farming, urban development
- Climate change: changing temperatures and weather patterns
- Human activities: pollution, tourism pressure
Reflection Question: Which threat do you think is the biggest, and why?
Cultural Connection: Māori View of Biodiversity
In te ao Māori, all living things have mauri (life force) and are connected through whakapapa. Endemic species are considered taonga (treasures) that have been gifted to Aotearoa. The concept of kaitiakitanga means we are guardians responsible for protecting these unique species.
Traditional Knowledge Example: Māori knew that when the kowhai flowers bloomed, it was time for certain fish to spawn, showing deep understanding of ecological connections.
Take-Home Experiment
Backyard Biodiversity Survey
Equipment: Phone camera, notebook, magnifying glass (if available)
Method:
- Choose a 2m x 2m area in your garden or local park
- Spend 15 minutes identifying all living things you can find
- Take photos and note which are native vs introduced
- Record your findings using the provided data sheet
- Upload findings to iNaturalist NZ (optional)
Extension: Compare your findings with a classmate's from a different area.
Assessment Task
Endemic Species Conservation Report
Task: Write a 300-word report on one endangered endemic NZ species, including:
- Why the species is unique (evolutionary adaptations)
- Current population status and main threats
- Existing conservation efforts
- Your proposed solution to help save the species
- Any traditional Māori knowledge about the species
Due: Next lesson | Assessment Level: Achieved/Merit/Excellence

Teacher Notes
- Preparation: Pre-assign species to pairs to ensure good coverage. Have backup species ready.
- Differentiation: Struggling students can focus on well-known species like kiwi. Advanced students can research lesser-known species like native frogs.
- Cross-curricular Links: Connects to Social Studies (Māori culture), English (report writing), Math (population statistics).
- Safety: If doing outdoor surveys, ensure students stay in designated safe areas and work in pairs.
- Extension Activities: Guest speaker from DOC, school conservation project planning, creation of species conservation posters.
