What environmental pressures might cause rodents to evolve social behavior?

Continuing from this question:

The rodents on the synthetic planet ( which I am now calling Ark ) can now walk/run erect when desired. The scientists continue with biological forging and work on there social behave , and the realize in hindsight that they probably should have worked on this first. The rodents live in an area with grass that is tall in relation to them , and smells slightly of mint. They run to and fro , dodging predators and carry twigs with large , sticky seeds or various small insects stuck to the ends.
