"An obvious caveat is that areas for which we detect little conversion of savannahs to croplands may still suffer human impacts that make them unsuitable for lions," the report said. "Over-hunting for trophies, poaching — of lions and of their prey species — and conflict with pastoralists may not have any visual signal to satellites. Even where there are low human population densities and areas designated as national parks, there (may) not be lions within them."
The report calls for more mapping and studying to be done to ensure the lions' protection.
