Priority one will be yellow sweet clover, because it’s easiest to find in bloom and flowering means that it will soon make long-lived seed if not checked.  We will attack it with power brush cutters, along with hand pulling scattered plants.  Priority two will be cutting sumac with brush cutters, assuming it’s to early to attack other herbaceous invasives besides yellow clover.  Bring eye and ear protection if planning to run a brush cutter.  There will be plenty of hand work. too.
