NASA satellites help endangered animal species

Tigers, jaguars and elephants share one sad thing in common: these species are in danger of extinction. The gradual disappearance of these animals is not due to chance, but to human activities which threaten their habitats. NASA therefore proposed to use its powerful satellites to detect areas where they could find refuge.

The tiger population has fallen by 93%.

Rehabilitate damaged territories

By observing the Earth daily and in detail, the satellites of the American space agency follow the evolution of habitats more precisely than is possible from the ground, and over areas as vast as those covered by certain wild animals. . By combining their observational data obtained from space and computer models capable of combining them with the Google Earth database, the researchers were able to highlight the existence of very large forest areas completely devoid of tigers, which nevertheless are known to have lived there.

The population of tigers that roamed Eurasia is said to have actually fallen by 93%, leaving no more than 5,500 individuals still alive. The covered area has been reduced by 11%. Faced with this alarming observation, the discovery of large spaces devoid of any tiger by NASA satellites could be considered for restoration. Indeed, in the past, these spaces were perfectly suitable for tigers. Properly rehabilitated and by directing the few remaining tigers there, researchers believe that they could serve as a cradle for their conservation.

The jaguars that roamed America are confined to a few areas in Argentina.

Preserve crucial areas

The same goes for jaguars whose population, which formerly spread from the United States to Argentina, has now fallen by 50%. NASA satellite observations have made it possible to demarcate areas in Argentina that should be converted into priority conservation areas for jaguars. Currently, deforestation is authorized in 36% of these areas.

Satellite data collected by the US space agency are therefore valuable tools for restricting the human footprint in certain refuge regions for endangered animals. It is still necessary that its conclusions be taken seriously and budgets allocated.
