Just north of downtown Houston, around White Oak Park, the banks of White Oak Bayou have been cleaned and a swampy area restored where birdwatching can be enjoyed. Yellow-crowned night heron and green heron nest there, and a number of eastern woodland birds also reside in and around the park. In addition, the White Oak Bayou Association, a non-profit organization dedicated to the preservation, restoration, and maintenance of wildlife habitats along the bayou, has been established as part of the Citizens' Environmental Coalition.
