* Trees are essential: Squirrels rely on trees for a variety of reasons, including:
* Shelter: They build nests and seek refuge in trees.
* Food: They gather nuts and seeds, which are often found in trees.
* Protection: They use trees to escape predators.
* Grass isn't a deterrent: Squirrels can move through grass just fine. They may choose to avoid areas of tall grass where they can't see potential threats, but grassy areas aren't inherently off-limits to them.
So, squirrels are likely to be found on grassy hills if those hills have trees nearby!
