One field where drone technology is making a significant impact is environmental monitoring. With the ability to fly over vast areas and capture high-resolution imagery and other data, drones will increasingly be used in the way we study and protect our natural environment. This article will explore the various applications of drone technology in environmental monitoring, from tracking the behaviour of wildlife and monitoring their populations to mapping and analysing vegetation, water resources, and air pollution. We will also discuss the benefits and challenges of using drones for this purpose and how the technology is currently being utilised.

Benefits Of Using Drones For Environmental Monitoring

Drones offer a range of benefits for environmental monitoring, including:

Monitor remote regions: One of the key benefits of using drones for environmental monitoring is their ability to access remote or hard-to-reach areas. Drones can easily fly over forests, lakes, or offshore areas to collect data that may be impossible to obtain by foot or vehicle. This makes it possible to monitor the environment in regions that may otherwise be overlooked or inaccessible.

Cost-effectiveness: Drones are a cost-effective option for environmental monitoring, particularly compared to traditional methods such as manned aircraft or field sampling. Manned aircraft are expensive to operate and require trained pilots, while field sampling can be time-consuming and labour-intensive. Drones, on the other hand, are relatively inexpensive and can cover a large area quickly, reducing the need for expensive equipment and personnel.

High-resolution imagery: Drones can capture high-resolution images that can be used to monitor changes in the environment. For example, drones equipped with cameras can capture images of deforestation, erosion, or changes in vegetation. These images can be used to create maps or 3D models, which can help researchers and environmentalists understand and respond to changes in the environment. 

Real-time data: Drones can collect and transmit data in real-time, allowing faster decision-making and more timely responses to environmental threats. For example, drones equipped with special sensors can collect air or water quality data and transmit it to a central database for analysis. This information can be used to identify environmental anomalies and respond to them quickly.

Safety: Using drones for environmental monitoring reduces the risk to human safety, as it removes the need for people to enter hazardous environments. For example, drones can monitor areas affected by natural disasters, such as wildfires or hurricanes, without putting rescue workers in danger.

Overall, drones offer a range of benefits for environmental monitoring, from their ability to access remote areas to their cost-effectiveness and safety. With their high-resolution imagery and ability to collect and transmit data in real-time, drones are becoming an increasingly important tool for environmental monitoring and protection.

How Drones Are Used For Environmental Monitoring

The use of drone technology for environmental monitoring has already shown promising results in a variety of contexts. For example, researchers have used drones to track the movements and behaviour of marine animals, such as whales and dolphins, in their natural habitats. This has enabled them to gather data on the animals’ populations and distributions and their interactions with their environment in a way that would have been difficult or impossible with traditional research methods.

For example, researchers from Macquarie University in Sydney, Australia, used drones to observe rays’ behaviour and habitat uses. In NSW, a whale monitoring program is utilising drone technology to track and ID southern right whales.

One of the benefits of using drones to track and monitor wildlife, whether on land or water, is that they are quiet and do not disturb the species that are being observed.

Drones are also being used to monitor and map vegetation, particularly in areas that are difficult to access, such as steep slopes, dense forests, and wetlands. This information can be used to study environmental changes, such as deforestation, and develop conservation and restoration strategies.

One company using drone technology for reforestation efforts is, combining both traditional methods of manual seeding and drones, droneseed hope to counter the effects of natural and man-made disasters and start the regeneration of forests more quickly.

Dendra Systems is another company that specialises in using drones and artificial intelligence (AI) to help reforest areas damaged or destroyed by human activity, natural disasters, or other causes.

Dendra Systems uses drones equipped with high-resolution cameras and sensors to collect data on the health and condition of vegetation. This data is then analysed using their proprietary software powered by AI algorithms to identify areas needing restoration. The company also uses drones to plant trees and other plant life in these areas, which can be done much more quickly and efficiently than traditional planting methods.

Drones can be equipped with different types of cameras, such as high-resolution RGB, infrared and multispectral sensors, to monitor water resources like rivers, lakes, and wetlands. This can help researchers understand water quality and quantity, detect pollution and contamination, and track ecosystem changes over time.

Drones can also be used to monitor air quality, collecting data on pollutants such as carbon monoxide, sulfur dioxide, nitrogen dioxide and other air pollutants. Drones equipped with air quality monitors offer several advantages over stationary air quality monitors. Drones are more mobile and flexible, can provide real-time data, are cost-effective, and can operate in hazardous environments to reduce the risk to human safety. Additionally, drones can collect high-resolution data and be customised to gather specific pollutant or environmental condition data, allowing for a more targeted approach to environmental monitoring.

One of the main benefits of using drones for environmental monitoring is that they can cover large areas quickly and efficiently, providing data that would take much longer to collect with traditional methods, such as on-the-ground surveys or manned aircraft. This can save time and money, as well as reduce the risk of human error and increase the accuracy of the data.

However, there are also challenges associated with using drones for environmental monitoring. One of the main challenges is ensuring that the data collected is accurate and reliable. This requires careful calibration of the sensors and cautious planning of the flight paths and data collection protocols. In addition, there are legal and ethical considerations, such as obtaining necessary permits and permissions, ensuring privacy, and minimising disturbance to wildlife.

Overall, the use of drone technology for environmental monitoring has great potential to improve our understanding of the natural world and to help protect it for future generations. As technology advances and becomes more affordable, drones will play a more prominent role in this field.

Types Of Drones That Are Used For Environmental Monitoring

Two types of drones are suitable for environmental monitoring, fixed-wing drones and multirotor drones, each with unique advantages and capabilities. Here are some examples of drones that are commonly used for environmental monitoring:

DJI Matrice 300 RTK: This drone is a popular choice for different commercial applications due to its ability to carry multiple payloads, such as RGB, thermal and multispectral cameras and LiDAR sensors. The drone has a long flight time of up to 55 minutes (without a payload), and with a payload, the flight time is between 30-43 minutes, depending on the weight of the payload. It also has a 15 km transmission range and a maximum speed of 51 mph, allowing it to cover large areas quickly and efficiently. The drone is also one of the best waterproof drones on the market, with an IP45 rating and can be operated in harsh weather conditions.
