その日も彼は、森の人々が町にやってきて悪さをしないか、森の見回りをしていた
What does the "か" mean here? is it an "if" or is it something else? Or am I overthinking this?

So the sentence means That day he was patrolling around the woods to see if the people there come to town and behave badly.
Normally those to see etc. are omitted.
Inserting (か)調べるために/確かめるために in the above sentences would sound lengthy.
