Introduction:

Memories of Abundance

Setting the Scene:

• Jamie (series presenter) standing lakeside on a beautiful morning, reflecting on the stunning natural beauty of the Rotorua lakes region

• Aerial Lake Tour: Voice-over accompanied by aerial footage showcasing the different lakes in the region

• Jamie walking toward the local school where tamariki are preparing for their morning task

• Children gathering equipment and preparing to check their catfish traps

Context Setting:

• Historical Abundance: Voice-over supported by archival footage showing traditional koura harvesting methods

• Living Memory: Kaumātua sharing stories of lakes so rich with koura that families could gather kai easily

• The Decline: Current reality of drastically reduced populations due to multiple threats

• The Catfish Problem: Introduction of how invasive catfish have devastated native koura populations

• Jamie's reflection: "Today we're witnessing an inspiring fight-back - communities refusing to let their taonga disappear"

The Journey Begins:

• Local tamariki leading Jamie to their catfish traps, explaining their role in species recovery

• First glimpse of the scale of the restoration work underway

• Introduction to the team of experts working to save the kōura

• Cascade Effects: How the loss of kōura affects the entire lake ecosystem

Community Response

• Youth Leadership: Local children taking action through catfish trapping programs

• Trap Demonstration: Kids showing Jamie their catfish removal techniques

• Community Commitment: How entire communities mobilized to address the crisis

Interview Questions for Act 1:

• Kaumātua/Elder: "What are your memories of kōura abundance in these lakes? How were they traditionally harvested?"

• Local Child/Youth Leader: "Why do you trap catfish? What have you learned about kōura?"

• Community Representative: "How has the loss of kōura affected your community's relationship with the lakes?"

Act 2:

Innovation & Action (Restoration in Practice)

Preventing Further Spread

• Aerial Footage: Structures installed in lakes to prevent catfish spread between water bodies

• Engineering Solutions: Technical approaches to containing the invasive species

• Monitoring Systems: How teams track catfish populations and movement

Habitat Restoration Techniques

• Bundle Construction: Cory explaining the technique of making effective kōura habitat bundles

Monitoring and Assessment

• Lake Monitoring: Joining Cory O'Neill and Sarah Wharekura on monitoring trips

• Fern Bundle Sampling: How fern fronds are used to assess kōura populations

• Catch and Release: The careful process of measuring kōura before returning them to the lake

• Data Collection: How monitoring informs ongoing restoration efforts

Traditional Knowledge Integration

• Mātauranga Māori: How traditional ecological knowledge guides modern restoration

• Seasonal Cycles: Understanding kōura behavior through traditional knowledge

• Sustainable Practices: Balancing restoration with cultural harvesting rights

Interview Questions for Act 2:

• Cory O'Neill: "How do you create effective kōura habitat using bracken ferns?"

• Sarah Wharekura: "What does the monitoring data tell us about kōura recovery?"

• Ian Kusabs: "How do the artificial stone wall structures support kōura populations?"
