Anti poaching drones are making a big impact in the saving of Rhinos, Elephants, Tigers, Gorillas and other critically endangered species. Drones with anti poaching technology are assisting Park Rangers across the globe and especially in Africa and Asia.
Drones are relatively cheap, can cover hundreds and even thousands of acres in a short space of time and can beam back live video transmission.
Using Infrared and thermal imaging, drones can also be used under the cover of darkness which is the favorite time of criminal poachers.

How Big A Crime Is Poaching Answered
The illegal wildlife trade is the 4th largest illegal trade behind drugs, people smuggling and counterfeiting. It is worth an estimated $4.5 billion annually. It has heavily depleted some populations and has brought others to the verge of extinction.
While the threats to flagship animals like elephants, tigers and rhinos are well known, other species don’t receive the same attention.
Yet illegal trafficking in both live and dead specimens, whether for pets, medicines, trophies, food or a host of other purposes, threatens a huge range of wildlife. Controlling it is a global priority.
Drones To Count, Protect And Manage Endangered Species And Habitat
Together with poaching, the deforestation and the destruction of rainforest and grasslands also cause species to become endangered. Fixed wind drones cover large land mass and are playing a big part in the reduction of illegal destruction of habits in nature reserves and parks.
Along with anti poaching activities, drone can fulfill all the following conservation tasks;
- Animal/flock counting.
- Camera trap image retrieval.
- Vessel monitoring (e.g. whaling ships).
- Animal tracking (e.g. via radio tracker collars/triangulation).
- Migration tracking.
- Perimeter assessment.
- Habitat management.
- Anti-poaching activities (identification, deterrence).
- Nest surveys.
- Species identification.
How Anti Poaching Drones Assist Ground Forces
Drones with surveillance anti poaching technology work with local rangers and communities to collect and analyse data to determine threat areas and to organize drone flight plans. Rangers are pre-positioned where they can be deployed quickly within the threatened areas.
Mobile command and control units are moved close to the threat areas and where drones can be flown from. Pilots fly the anti poaching drones along pre-planned routes from analyzed data. They can also easily change direction through analyzing the live data if wildlife or potential poachers show different movements . Most poaching happens at night under a full moon. Drones with infrared cameras and thermal vision cameras are essential and can detect movement at night.
When poachers are spotted the drone operators in the mobile command center radio the location of the poachers to ground troops which are close by. The rangers can then swoop in and catch the criminals. All data is stored and analysed to assist with future missions and to understand patterns used by poachers.
Anti Poaching Drones With Sensors
Fixed wing anti poaching drones carrying a variety of sensors and technology are used. Most anti poaching projects now use a combination of fixed wing and quadcopters. The long range drones can be used for quick scans and a large overview. Smaller drones can be used when threat areas are detected, mobile units and ground Rangers are close by.
Drones With Sensors, Predictive Analytics And Pattern Recognition
Anti poaching drones uses powerful control systems and sensors which give them extraordinary capabilities which are ideal for the anti-poaching mission.
Every drone will have a solid-state inertial system (IMU) that maintains its flying attitude, regardless of winds, etc. The drone will also have an internal GPS receiver which tells the aircraft where it is (and where the cameras are looking) at all times.
Some anti poaching drones will have at least two zooming camera systems which are carried on gyro-stabilized gimbals. These keep the cameras pointing at the same location, regardless of bumpy air or heading changes.
One camera is designed for visible light and is operated during the daytime; the other is an infrared sensing device that provides thermal imaging (heat signatures) during hours of darkness.
In the future, we may also see ToF sensors been used as Time-of-Flight cameras on drones have the ability to “see” into obscurants such as fog, smoke, mist, haze and rain.
On-board datalink communications keep the aircraft in touch with the Ground Control System, sending navigation, piloting and camera operation instructions to the aircraft and downlinking positional and live video streams from the camera systems. The communications links are encrypted for security.
Turning raw data into real information is vital. Predictive analysis integrates several factors including: the poachers’ known past behaviors, terrain information (elevation data, trafficability data), and the movement patterns of wildlife.
The platform develops a coordinated theory which has been successful in all tests and live applications.
Mobile Command Center
This is generally a highly equipped modified vehicle and will contain everything required for a mission such as;
- Remote controlled aircraft and avionics.
- A variety of mounted cameras to accommodate day and night (infrared) surveillance.
- Accessories such as antennae, batteries and trackers.
- Radio and communication systems.
- Support services such as Geographical Information Systems (GIS) mapping, database capacity and recording software.
- Monitoring equipment and software.
- Spare parts and maintenance tools.
- Support services for the crew such as tents, beds, rations, etc.
Here is a quick overview of how drones are making a big difference in stopping poaching.

Air Shepherd Expands to Malawi
Expansion of operations to Malawi, where they are flying in Liwonde National Park and Nkhotakota Wildlife Reserve.
In 2012, with the onset of the rapid increase in wildlife crime and specifically rhino poaching, Ezemvelo KZN Wildlife entered into an agreement with a service provider to undertake a pilot rhino security aerial surveillance and monitoring project using UAVs. The main objective was to reduce rhino poaching attempts and provide effective protection of the Hluhluwe, iMfolozi Park (HiP) rhino population.
This project continued for a period of two years, and the mortality statistics from start to termination of the project clearly showed a significant decrease in poaching mortalities: a 65% reduction in rhino poaching compared to the previous year. Since that time UAV tactics have been upgraded resulting in no poaching deaths in any area where drones were flying in the last six months.
The decrease in poaching is greatly attributed to the presence of drones in the park, combined with other strategic law enforcement and monitoring projects and operations.
Here is a terrific video which talks about the problem of poaching and the Air Shepherd initiative.

FX-61 Drone Assists With Rainforest Conservation in Suriname
Suriname in the north east of South America recently organized a drone training for nine rangers working for Suriname’s Nature Conservation Division. The goal of the training was to educate the rangers on how to use drones to monitor the vast tracts of forest they are charged with protecting.
Conservation drones capture detailed high resolution images of objects on the ground. This may include human activities that threaten nature, like illegal logging, mining or poaching.
With the help of drones, the rangers should be able to map areas of interest and detect threats more easily than before, when rangers’ routes were limited by roads, cost and time.
The rangers were trained in the use of a FX-61 fixed-wing drone. They learned how to set up the drone, prepare it for use and plan its missions on a computer that communicates with the drone. Read further on the terrific Suriname rainforest conservation project.

Skywalker Drone – Sumatran Orangutan Conservation
The Sumatran Orangutan Conservation Program is endeavoring to conserve viable wild populations of the critically endangered Sumatran orangutan.
The SOCP team focus on habitat protection, rehabilitation and reintroduction of ex-captive orangutans to the wild, education, survey work and scientific research.
Since 2012 the SOCP has been working closely with Dr Lian Pin Koh and Dr Serge Wich and colleagues at conservationdrones.org to develop innovative remote control aerial surveillance drones.
They are using standard remote controlled UAVs, adapted to carry either video or still photographic equipment along with an autopilot system. The autopilot can be pre-programmed to fly at any height and follow a particular route, such as following the forest edge, or to cover a given area with a specifically designed transect system.
The on board still camera can also be programmed to ensure photos overlap, so that they can then be stitched together to produce a mosaic, and even tied to a less detailed satellite image, giving a much more detailed view of a selected area of the image. In this way, they are able to survey areas which would be very difficult to reach otherwise, up to as far as 15 mile or more from a launch site.
Potential uses for this new technology seem limitless. Not only do they include habitat monitoring and research, they can use drones to photograph orangutans in trees and their nests.
In the future they will be able to detect radio transmitter chips implanted into reintroduced orangutans. This would be of an enormous help in monitoring the progress of orangutans newly reintroduced to the wild, something which is not easy to do from the ground.
Currently, the SOCP team primarily flies with the Skywalker fixed wing airframe.
DJI Inspire 1 Drone
In general fixed wing UAVs are necessary to cover large areas. However most fixed wing don’t have the ability to hover in place to grab accurate stills or film which may be necessary to prosecute illegal poaching and logging. One of the best quadcopters to accompany fixed wing conservation drones is the DJI Inspire 1.
What really makes the Inspire 1 excellent for professional aerial filming, surveying and conservation is it’s super flight stability and it’s terrific range of camera options. It has terrific gimbal cameras options including the Zenmuse XT thermal imaging and Zenmuse Z3 zoom camera.
Zenmuse XT Thermal Imaging
The thermal imaging sensor is from FLIR which are world leaders in thermal imaging systems, visible-light imaging systems, locator systems, measurement and diagnostic systems, and advanced threat detection systems.
The Zenmuse XT thermal camera provides image and video details which the naked eye could never spot by making subtle differences in temperature visible. Thermal images cameras are essential for night time viewing where almost 100% of criminal poaching activities take place.
Zenmuse Z3 Camera (Zoom)
The DJI Zenmuse Z3 is an integrated aerial zoom camera based on DJI’s class leading Zenmuse X3 and optimized for still photography. A 7x zoom made up of 3.5x optical and 2x digital lossless zoom creates a 22 mm to 77 mm equivalent focal length range, making it ideal for most applications.

The SenseFly eBee drones in a uniquely flexible tool. It is available with multiple camera payloads, so you need only invest in the configuration that suits your conservation requirements.
The camera, or payload, which a drone carries directly influences the imagery it can capture and therefore its potential usage. Here’s a quick guide to the most common used aerial imaging sensors on the eBee:
- Professional-grade RGB: surveying/geospatial.
- Thermal infrared: anti-poaching / photovoltaic/rescue/environmental.
- Multispectral: agriculture/forestry/conservation.
Like the camera in your smartphone or SLR, RGB sensors acquire data in the visible spectrum (specifically Red, Green & Blue bands). The images they produce can be transformed into 2D orthomosaics (A.K.A. orthophotos) and 3D digital surface models. Such sensors have been used, for example to create terrain models of glacial features, monitor coastal erosion, perform volume measurements etc.
The technology in 3D maps, also known as photogrammetry maps is the science of making measurements from photographs. By flying a mapped route and taking photos at regular intervals of say every 1 second, these images are then stitched together to create 3D photogrammetry images.
To create 3D maps or models, all you need is a top drone with camera and GPS. The drone should be programmed using waypoints to capture images at say 0.5 or 1 second intervals. Then, to create the 3D maps a top photogrammetry software application will be used to stitch the photos.
3D maps are generally quite large and take a lot of processing. Most of the 3D mapping software companies can process the images in the cloud and also store the images for you.
Near-infrared (NIR), Red-edge (RED) And Multispectral Cameras
These cameras acquire data across bands in the visible and non-visible spectrums. This type of data enables users to compute vegetation indices in order to create reflectance maps for assessing plant health, estimating biomass and more.
Temperature measuring thermal cameras, assign a temperature value to each pixel. The have already proved highly useful in conservation projects to count treetop Orangutan nests in Indonesia and assess the fight against Rhino Poaching in Namibia.
All of the above drones are doing terrific work in catching poachers, who are destroying our beautiful wildlife, pushing many to the edge of extinction.
