Trees and brush along the riverfront offer habitat for many small animals such as fox, raccoon, possum and beaver. Sandbars in the river are annual nesting sites for the endangered Interior Least Tern which is federally protected. During the winter months, Bald Eagles nest along the river corridor and raise their young. Park users can catch glimpses of the magnificent birds swooping for prey. In addition to songbirds, herons, pelicans and gulls can be seen in different seasons along the riverfront.
Much of the riverbank is lined with mature trees. River Parks’ landscape management includes regular planting of new trees with emphasis on native species that are disease-resistant and provide seasonal color. Brush along the riverbank is maintained to aid erosion control and provide wildlife habitat. Landscape plantings generally feature low maintenance grasses and shrubs, with limited flowering species. Storm damage is the greatest threat to River Parks’ urban forest, with many trees lost each year to high winds.
