Reintroducing the Salmon to Its Historical Habitats (Ex-Situ Conservation)

Following habitat restoration efforts, including the removal of silt traps and reforestation along riverbanks, the salmon were reintroduced to five historical streams. Technologies, such as mini radio transmitters, were used to track the salmon’s behavior and assess the suitability of their restored habitats.

  • The Formosan landlocked salmon is a keystone species in stream ecosystems, with its presence helps maintain ecological balance. Restoring populations in historically distributed areas promotes the integrity and stability of local ecosystems.
  • The three-phase goal set at the 2000 Formosan Landlocked Salmon Conservation Research Symposium aims to restore its natural habitats, expand the species' natural distribution range, and reduce survival risks posed by issues like climate change.
  • The 2005 Wuling Stream Long-Term Monitoring Integrated Plan (2005-2013) involved monitoring habitats and species prior to the silt trap improvement plan, laying the groundwork for the restoration of ecosystem balance.
  • In 2017, a cross-regional collaboration with Taroko National Park enabled the release of Formosan landlocked salmon into Hehuan and Nanhu rivers, which are at higher elevations than the Qijiawan River.
  • Releasing salmon into different streams and different sections of the same stream fosters evolutionary diversity, contributing to the genetic diversity of the Formosan landlocked salmon.
  • In October 2023, a breakthrough in reintroduction techniques overcame the challenge of transporting fish over long distances. Through waterless transport, the eggs were transported and reintroduced into the upper reaches of Nanhu River, at an altitude of 2,200 meters in Zhongyangjian River.
  • In 2004, Typhoon Aere brought heavy rains and landslides that destroyed the hatchery along the Qijiawan River. The previous efforts were washed away, causing a 2–3-year disruption in the off-site conservation work. However, researchers and conservationists, equipped with prior experience, remained determined to persist in their efforts. To mitigate the impact of future extreme weather events, they also began releasing salmon into multiple streams, dispersing the risks associated with such climatic challenges.
Building Cross sectoral Partnerships

Hack The Planet acknowledge that our partnerships allow us to combine strengths, resources, and expertise, amplifying the impact and fostering innovative solutions. Collaborating creates shared value and builds networks, enabling mutual growth and sustainability.

Scanneredge is a collaboration with Tech for Conservation organisation Smartparks, Management of national parks like Gonarezhou - Zimbabwe, park technicians, rangers(QRU) and the local community. Through this cross-sector partnership, we have demonstrated that ScannerEdge is ready for broader deployment, increasing the number of active national parks and total scanners in use.

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.

Scanneredge offers a plug&play innovation offering a quick installation that can be monitor the area for signs of potential poachers immediately after installation. 

The true success depends on the internal Rangers Quick Response Unit's ability to act swiftly and effectively on the real-time data provided. The unit must remain on constant standby, equipped with reliable transportation, and prepared to respond on poaching activity.

Building trust among stakeholders takes time but is essential for long-term collaboration.

Cross-sectoral partnerships increase funding opportunities and knowledge sharing, enhancing the overall impact.

Quick Response Unit acting on suspicious threats based on real-time data

Leveraging real-time alerts from ScannerEdge, a response unit can quickly assess and mitigate potential threats, such as poaching or other illegal activities.

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.

Response protocols must be clearly defined to avoid delays in decision-making.

Collaboration with local enforcement agencies enhances the effectiveness of rapid response teams.

Real-time response is more effective when combined with predictive analytics based on historical ScannerEdge data.

Committee establishment, formalization and operationalization

Inclusive and participatory mapping of all stakeholders in the mangrove space in the five counties of Kwale, Mombasa, Kilifi, Tana River and Lamu. A series of meetings for sensitization on the National Mangrove Management Plan, and later facilitated formation of the national and five county committees. The committees were then facilitated in developing their workplans and executing some of the activities. This has since been picked up. 

Partnership and collaboration.

Inclusive processes

Willingness and trust amongst partners 

Encourage the generation of a chain that increases the commercial value of the guanaco fiber by linking the primary production sectors with the national and international textile sectors.

Work with different actors at the local, national, and international levels, to contribute to the design of a fiber value chain that can trigger the activity. The work will consist of the identification of key public and private actors in order to provide tools for the commercialization of the product. The activities that will be developed in this stage of the project include meetings with the textile sector, application authorities, and various important local actors in this area.

-Meetings with representatives of national organizations to evaluate background, regulations, marketing, and support possibilities for wild guanaco management experiences.

-Meetings with selected fashion designers at the national (i.e Buenos Aires) or international (i.e Canada) scale, to generate a fair value chain and promote WFA experience.

-Value-added options will be identified at the national/international level through meetings with actors from the public and private sectors, to expand WFA as a “Based nature Solution".  

Wildlife camelid management actions began in the 80s, based on the philosophy of the "ICDPs", seeking to link biodiversity conservation with improving the life quality of life of local people. These projects, which initially focused on the vicuña, were based on the application of economic incentives to promote the use of wildlife. We prove that wild guanaco use could improve the numbers of those initiatives because of the wider distribution range of the species. In Argentina, the production of SAC fiber could easily double due to an increase in the number of sheared populations and an increase in the frequency of shearing. This would clearly lead to a change in the production paradigm in contrast to the current one. Guanaco fiber is amongst.The Cooperative decided to add value to the raw fiber in order to increase the value. By 2010, most of the projects had stopped due to difficulty in marketing guanaco fiber with a price of USD $40-60 per kilo. The "problem" is there are only two trade companies that buy raw fiber that is exported mainly to Italy and control the market prices. 

Module 5: Community Awareness and Early Warning Promotion

Early warning messages are primarily distributed through channels such as the early warning app, intelligent broadcasting, phone calls, and SMS. Among these, the early warning app is the most widely used method, covering the largest population. Monitoring personnel can also share messages from the app to WeChat groups or personal networks, enabling multiple rounds of dissemination and further extending the reach of early warnings. Expanding the user base of the early warning app is therefore critical. To maximize coverage among residents in elephant-affected areas, the monitoring teams have conducted in-village promotional campaigns to encourage app adoption. As of now, the early warning app has been downloaded by 246,661 users.

  1. Safety Awareness Among Residents: The strong demand from residents in elephant-affected areas to ensure their safety has driven engagement with the early warning system.
  2. Community-Friendly Outreach: Monitoring teams conduct in-person visits to villages and households, fostering trust through approachable and relatable communication.
  1.  Continuous Training: Regular training sessions are essential, particularly for transient populations and vulnerable groups such as the elderly, children, and individuals with disabilities.
  2. Impact of Targeted Warnings: Precise delivery of early warning messages via phone calls and SMS has significantly influenced community residents’ ability to take timely protective actions.
Module 4: Supporting Monitoring and Early Warning Platform

All monitoring data collected by drones and infrared cameras is transmitted in real time to the early warning platform via a network connection. The system automatically matches location data and generates early warning messages. These warnings are delivered to end-users through both broad-based channels (mobile apps, WeChat) and precise channels (SMS, phone calls), ensuring community residents receive timely alerts and can take appropriate actions. To date, the platform has issued over 130,000 early warnings.

  1.  Automated Data Matching: The platform’s database features an automated matching function that ensures efficient and accurate early warnings.
  2. Comprehensive Distribution Channels: The use of various channels (mobile apps, SMS, phone calls) ensures the coverage of different community needs, catering to diverse user groups.
  1.  Platform Optimization: The database must be regularly optimized to maintain the speed and accuracy of early warning information matching.
  2. Multi-Channel Delivery: Expanding distribution methods, such as incorporating intelligent broadcasting, can significantly improve community residents’ reception and responsiveness to warnings.
Module 3: Optimization of Big Data and Intelligent Recognition System

The infrared camera system transmits a large volume of triggered photos daily, including images of other animals or humans. By leveraging artificial intelligence, the system has been trained to effectively recognize and filter out non-elephant images, achieving an identification accuracy of over 99%. Even partial images or shadows can be accurately identified. The backend system completes the process of issuing early warnings within 13 to 15 seconds through a fully automated workflow, significantly reducing manual intervention and enhancing the intelligence and automation of Asian elephant management. To date, the system has captured over 3 million images and automatically identified and issued 12,285 early warnings.

  1.  Advanced Artificial Intelligence Algorithms: The implementation of powerful AI algorithms ensures high-precision image recognition and efficient data processing.
  2. Unified Data Aggregation: Data from various regions is consolidated, supporting big data analysis and providing a foundation for long-term conservation planning and decision-making.
  1.  Algorithm Updates: The monitoring and recognition system requires regular algorithm updates to adapt to environmental changes and improve recognition accuracy.
  2. Efficient Database Management: A robust and efficient database management system is essential to ensure that data can be easily analyzed and utilized for conservation purposes.
Modular Drone Technology

Our modular drones are designed for accessibility, adaptability, and sustainability. Initially crafted using wooden components with fewer than six screws and zip ties, they are simple to assemble, repair, and replicate using local materials, empowering communities to lead restoration projects independently.

These innovations enable drones to cover larger areas and operate in remote environments while reducing their carbon footprint.

The modular design ensures flexibility for continuous adaptation, allowing communities to upgrade drones with tools like cameras or sensors for monitoring. This approach combines simplicity and cutting-edge innovation, bridging grassroots empowerment with scalable, impactful environmental restoration.

Results

Under the application of the trap for intermittent harvest, the best results were achieved with the following combination of variables: maize bran (supplementary feed) x maize bran (trap bait) x O. Shiranus (species) x 2 fish/m2 (stocking density).

The total yields under this combination were 25 percent higher than in the control group with single batch harvest. A higher stocking density (3 fish/ m2) led to a slightly higher total harvest in the control group, but to a lower net profit. The use of pellets reinforced both effects and was the least economical.

Results from the on-farm trials (see Figure 1) have demonstrated the functionality and the excellent catch effect of the traps. Over the three-month on-farm trial period, the trap was used 2 to 3 times a week and a total of 27 times. On average, around 120 small fish – an equivalent of 820 grams – were caught each intermittent harvest. With the use of the trap, all households reported that they now eat fish twice a week. Before that, fish consumption was between one and four times a month.

The benefits:

  • Reducing the competition for oxygen and food among the fish in the pond and thus measurable increase in yield.
  • Improved household consumption of small, nutritious fish and better cash flow.

Success factors:

  • Traps are easy and inexpensive to build (USD 3).
  • Traps are easy to use, also for women.
  • Directly tangible added value thanks to easy and regular access to fish.

 

Examples from the field

Overall, the user experience of households engaged in the on-farm trials was very positive:

As a family we are now able to eat fish twice and sometimes even three times a week as compared to the previous months without the technology when we ate fish only once per month.” (Doud Milambe)

Catching fish is so simple using the fish trap and even women and children can use it.” (Jacqueline Jarasi)

It is fast and effective compared with the hook and line method which I used to catch fish for home consumption that could take three to four hours but to catch only three fish and thus not enough for my household size.” (Hassan Jarasi)
