Fred: This is what is called a "rush"  "Juncus effusus" is the scientific name. It needs wet areas to thrive but  can stand some dry periods. As you noted, livestock won't eat it though it doesn't;t seem to be poisonous.

There are some herbicides that can control it though that won't keep it from coming back from seed  if the swampy conditions are still there. 

Give me a call and we can discuss the possible herbicide choices. Chip Bubl OSU Extension Agent/Columbia County retired<personal data hidden>
