Yosemite Rivers Alliance is inviting plant nurseries to bid on the cost of providing native plant seeds, plants, and trees and shrubs for a grant-funded floodplain restoration project near the town of Modesto, CA.


The project improves ecosystem level function (improved riparian habitat) and provides functional floodplains that can accommodate flood flows. The project primarily benefits anadromous fish (Chinook Salmon, O. mykiss, Pacific lamprey) although we anticipate it will also benefit amphibians (Western Pond Turtle, Foothill Yellow-legged Frog, CA Tiger Salamander, etc), reptiles, and avian species.
