DALLAS (AP) — Crews worked Sunday to protect two sensitive wildlife areas after a crude oil spill shut down parts of a major southeast Texas port, state Land Commissioner Jerry Patterson said.

Plastic walls known as booms and oil-sucking skimmer boats were used to safeguard a lake that is a crucial breeding ground and a wildlife management area that lost its protective gates when Hurricane Ike roared ashore a year and a half ago, Patterson said.
