Our world is facing an unprecedented rate of extinction. According to the World Wildlife Fund (WWF), over the past 40 years, we have lost half of our wildlife populations. Climate change, habitat loss, and poaching are some of the most significant factors contributing to the alarming decline of wildlife populations. Yet, despite the urgency of the situation, monitoring wildlife populations is a labor-intensive process. Researchers have to cover vast areas of terrain, often inaccessible to human beings, to get a complete picture of the health and demographics of animal populations. This reality highlights the dire need for more effective techniques to monitor wildlife populations
Drones have revolutionized wildlife monitoring significantly. Unmanned aerial vehicles (UAVs) are an affordable and efficient alternative to traditional monitoring methods, providing insightful data and allowing researchers to make informed decisions to protect animal populations better.
The Benefits of Drone Monitoring in Wildlife Conservation
1. Accurate Counting
Counting the members of a wild animal species precisely is a difficult task, even for experienced field researchers. Drones can help resolve this issue by offering a bird’s eye view of the landscapes, allowing for clear, accurate photos and videos of the target species. Combining these high-resolution images with machine learning algorithms and computer vision can provide precise animal counts. The system can also estimate age, sex, and individual identity in some cases, providing valuable information about the demographics of a population.
2. Habitats Monitoring
Drones can also help in monitoring wildlife habitats by surveying the vegetation, water resources, and changes in the climate that may influence wildlife populations. They can also identify and locate potential dangers in an area, such as poachers, allowing wildlife managers to act before it’s too late.
3. Cost-Efficient and Time-Saving
Traditional methods for counting, monitoring and patrolling endangered animals include manned helicopters, radio-collars, and camera traps. Unfortunately, these techniques are quite expensive, logistically complex and often miss crucial visual data. Drones, on the other hand, are cost-efficient, easy to use and can cover vast areas of terrain in a fraction of the time. Drone monitoring can significantly save both time and money in the grand scheme of things.
Examples of Wildlife Monitoring using Drones
Several organizations have incorporated drones in their wildlife conservation efforts:
1. Wildlife Protection Association of Australia
The Wildlife Protection Association of Australia (WIRES) is using drones to locate and monitor Koala populations in New South Wales. This initiative aims to gather information about the Koalas, including their approximate numbers, health status and distribution, and habitat preferences. The data collected from this project will help WIRES develop effective conservation strategies to protect Koalas and their habitats.
2. African Parks
The African Parks Organization has used drones to monitor, count, and protect elephant and rhino populations in South Africa. African Parks combines the data from the drone footage to the data from tags attached to the animals to track their whereabouts.
3. Tahltan Central Government
The Tahltan Central Government, working in conjunction with university researchers, developed a drone project to monitor caribou populations and their interactions with wolves in Northwest British Columbia. Researchers hope to gain a better understanding of the dynamics at play in this fragile ecosystem and protect the caribou from further population declines.
Challenges in Drone Monitoring of Wildlife
While drones have proven useful in wildlife monitoring, several challenges remain unresolved:
1. Legal Frameworks and Regulations
Enacting regulatory frameworks governing drone systems for wildlife conservation remains a challenge. The diversity of jurisdictions across different countries and states heightens the complexity of regulating drone use without compromising wildlife populations’ data privacy and safety.
2. Technical Issues
UAVs have limited battery life and face environmental challenges such as strong winds and inclement weather. These challenges, combined with the need to fly at low altitudes, require drones to be agile, reliable, and capable of gathering data quickly and efficiently in as short a time as possible.
3. Public Perception
Drone utilization for wildlife monitoring in the ecosystem remains a largely unfamiliar concept to the public. As such, it has led to resistance to its implementation. The potential for drones to invade privacy or appear threatening is something that requires active communication and education to the public.
The Future of Drone Monitoring for Wildlife Conservation
The adoption of drone technology in wildlife conservation continues to expand rapidly, with leading conservation organizations such as the WWF and The Wildlife Conservation Society taking the lead in incorporating UAV technology in their conservation efforts. However, future research into the remote sensing techniques accessible to drones, their capacity to monitor changes in climate and vegetation, and drones’ involvement in sectors beyond wildlife conservation such as forestry is necessary.
Drones have revolutionized wildlife monitoring, offering a viable alternative to the traditional methods that were costly, time-consuming and less effective. The potential for drone utilization in wildlife monitoring is vast, providing accurate data, insights and protective measures to the ecosystem. However, challenges lay on the horizon that must be addressed, such as public perception, technical issues, and legal frameworks and regulations. It’s safe to say that drones are an essential tool in the fight for Wildlife Conservation and will continue to play a significant role in conserving and preserving our petrified wildlife species.
