Buffalo Bayou slowly winds its way through the center of the fourth largest city in the United States. Over the past 170 years of Houston's development and continued growth, the natural habitats of Buffalo Bayou have been impacted by human development, invasive species introduction, and pollution. The Conservation Division of the Buffalo Bayou Partnership works to rebuild the native habitats of Buffalo Bayou through intensive, volunteer-based restoration programs.These programs include: erosion control, reforestation, habitat improvement, and species diversification.
