Conservation of wildlife requires accurate tracking of their population so that scientists can get a better idea of how many species of a certain animal exists. However, things get quite challenging when it comes to tracking the population of wildlife found in the water and in inaccessible areas. Take arctic regions, for example. Not only are these species at high risk of becoming extinct due to climate changes, but certain species are extremely vulnerable to poaching and hunting.
These activities kill species faster than anything, causing habitat loss. The same goes for polar bears. In order to preserve their species, it is important for people to identify the number of polar bears existing in the world.
This will help them deploy effective measures to control the extinction of this wildlife and ensure their protection in all seasons and environmental conditions. It isn’t only about identifying the number of polar bears, but it’s equally important that scientists understand how climate changes and pollution affect the population of this species. Besides that, scientists need to know the movement of polar bears in relation to the snow. The question is how do scientists perform this research?
GIS in Tracking the Population of Polar Bears
The applications of this remote-sensing technology have extended to Antarctica. Thanks to the satellite-based images. It has now become possible for researchers and scientists to collect 3D pictures of the land and areas that can’t be evaluated manually. These images offer a lot more information than the data about species. It shows you how far the particular animal has traveled, how is their movement associated with the sea ice, and how long it takes these bears to adapt to the new environment.
Later, this data shows us where the polar bears are likely to go and how exactly do they adapt to different environmental conditions. In addition to collecting information about the polar bears, scientists use 3D imaging tools to gather more data about the health of this species. These satellite-based images give you an accurate picture of the length and weight of the bear. Based on this, they can take the sample of fat, hair, and blood of these species so that they can check them for the signs of contamination or any disease that’s likely to spread to other bears.
How can GIS be Used to Track Polar Bears?
GIS can be used for tracking the movements of the bear. They use a tool called a collar, which sends important signals to the satellite, helping scientists track the path the bear has traveled. However, the collar works for only the female bears. The male polar bears have a neck that exceeds the size of their head, making it nearly impossible for the collar to stay stuck to the neck. As a result, the collar simply falls off their neck. The collar sends information to the satellite, which then passes this data to the scientists, making it easier for them to conduct research as needed.
