The caveat to that being the other experience requirements kind of preclude you from being eligible if you don't have any other experience in the field. So to answer your question, it won't hurt for getting an entry level position, but where it would be most helpful in getting you a bigger paycheck, its either not closely related enough to count or there is other experience that is required.
Masters are most useful when applying to a field they are closely related to; ie. using a masters degree in forestry, wildlife science, agriculture, environmental science, etc. to qualify for any of the closely related "Forestry Technician" positions in the FS. It helps when beating the algorithm.
