Photonics is changing how we understand and protect wildlife. With tools like LiDAR, thermal imaging, and remote sensing, scientists can track animals, check habitats, and solve problems between people and wildlife. Here below you will see 5 examples of how technology can contribute to understanding and protecting wildlife:


Animal Tracking Devices
Animal tracking devices, like GPS collars and tags, are crucial for scientists studying animals like elephants, sea turtles, and birds. GPS uses special light-based technologies, like lasers and optic fibers, to send and receive signals from satellites, helping us figure out exactly where we are on Earth
. They help us understand where animals go, why they go there, and how we can protect them better. By tracking their movements, we learn about migration patterns and critical habitats, especially for endangered species. These devices also help us understand animal behaviour and how they interact with their environment, contributing to conservation efforts and keeping our planet's wildlife safe.


Camera Traps
Camera traps use special light-based sensors and cameras to take pictures or videos of animals from a distance. These cameras turn on when animals move in the wild and take pictures and videos of them without people getting in the way. They show us how animals behave, how many of them there are, and what kinds of animals live in far-off places where it's hard for people to go. They help scientists learn more about wildlife without interrupting them and help protect animals by keeping an eye on their homes and making sure they're safe.



Drones are flying objects and can be equipped with cameras. They help scientists learn about animals and their habitats in hard-to-reach places. They take pictures and collect information on things like where marine animals live, the health of coral reefs, and if people are illegally hunting animals. This helps us understand wildlife better and protect their homes, while also keeping an eye on environmental changes and helping with wildlife conservation efforts worldwide.


Environmental DNA (eDNA) Analysis
Scientists use environmental DNA (eDNA) to study animals. They collect samples of soil, water, or air and check for the DNA animals leave behind. Photonics-based equipment is used to analyse these samples to figure out which animals are around, even if they're rare or tricky to spot
. This method is great for studying shy animals and understanding habitats without having to see the animals themselves.
