• The Formosan landlocked salmon serves as a vital environmental indicator; protecting this species contributes to overall environmental improvement.
• Environmental education initiatives include interpretive services and guided tours along Qijiawan River, collaborative community and tribal education efforts, conservation-focused courses and ecological camps designed with schools, and volunteer recruitment for hands-on conservation work.
• Plans are underway to introduce immersive experience classrooms, where participants can wear wetsuits and enter the stream to observe the Formosan landlocked salmon in its natural habitat. These experiences aim to deepen public understanding, foster care, and inspire action to protect stream ecosystems and water resources.

• High-altitude agriculture in the upper Dajia River and its tributaries polluted the ecosystem, with water quality degradation being a primary factor in the near extinction of the Formosan landlocked salmon.
• An intact forest environment supports the three critical conditions for the salmon's survival: temperature regulation, food availability, and clean water.
• In 1997, plans were initiated to install wastewater treatment systems to manage sewage from Wuling Farm and surrounding recreational areas, with the first plant becoming operational in 2002.
• Negotiations with Wuling Farm facilitated its transition toward eco-tourism, reducing agricultural activities and reclaiming farmland for reforestation.
• In collaboration with the Forestry Bureau, 500,000 native trees were planted along the Qijiawan River and on reclaimed farmland to restore the riparian ecosystem.
• In December 2006, the final 8.1 hectares of private land in the Wuling area were acquired, ensuring the Qijiawan River habitat remains free from pollution caused by high-altitude agriculture.

• The conservation initiatives launched in the 1980s ultimately faced setbacks, with efforts declared unsuccessful in the 1990s. Key challenges identified included the absence of deep pools and typhoon shelters in high-altitude streams, along with disrupted habitat connectivity caused by silt traps.
• Between 1999 and 2001, four silt traps on Gaoshan Creek, a tributary of Qijiawan River, were gradually removed or improved, leading to the observation of natural spawning by juvenile salmon.
• In 2010, an assessment revealed that the No. 1 silt trap at the lowest part of Qijiawan River was a critical bottleneck, and it was removed in 2011.

• The Formosan landlocked salmon, discovered in 1917, is a unique species that is considered a "glacial relict." It is found exclusively in the high-altitude streams of central Taiwan, marking the southernmost and highest-altitude wild distribution of any salmon species in the world. This species is regarded as a natural monument and an iconic national treasure.
• By 1984, the Formosan landlocked salmon was nearly extinct, with 90% of its historic range across five streams reduced, leaving only about 200 individuals.
• In 1989, the Wildlife Conservation Act was enacted, listing the Formosan landlocked salmon as an endangered species (EN), signaling the urgent need for conservation.

To establish a successful cross-sector partnership, it is essential to clearly define each partner's role and level of involvement from the outset. Ensuring local ownership of the solution is crucial for achieving long-term sustainability and impact.

Purpose: To align resources, expertise, and strategic goals across different sectors for effective implementation and operational success.

How it Works: Partnerships are built through workshops, shared missions, and transparent agreements outlining roles and responsibilities. Regular evaluations ensure partnerships remain productive.

Purpose: To translate RF signal detection into actionable insights that trigger swift response actions in the field.

How it Works: Alerts are routed to dedicated response teams equipped to investigate and intervene. ScannerEdge’s GPS functionality and integration into EarthRanger aids in pinpointing signal sources for precise action.

Purpose: To provide real-time intelligence on human presence or illegal activities by detecting and analyzing RF signals within a 3 km radius.

How it Works: ScannerEdge scans for RF signals (UMTS, Wi-Fi, Bluetooth, satellite phones, and VHF radios) and transmits alerts via LoRaWAN or satellite connectivity. Data is centralized for further analysis and decision-making.

Purpose: To equip field teams with the skills and knowledge to install, operate, and maintain ScannerEdge devices, ensuring continuous functionality in diverse environments.

How it Works: ScannerEdge is installed in strategic locations, configured via Bluetooth through a smartphone app, and calibrated to local RF conditions. Training includes understanding signal detection, troubleshooting, and device maintenance.

Partnership and collaboration.
