Amazon Prairie Mitigation Bank 

Project Information

Phase one of the Amazon Prairie restoration is well underway. In the coming years, Amazon Prairie will transform into wetlands, upland prairie and riparian habitat enhanced to support a wide range of plants and animals. 

Phase one of the Amazon Prairie restoration project covers 148 acres of the 329-acre site. Work already completed includes: 

  • Excavation of 18 seasonal pools. 
  • Distribution of 500 pounds of native seed, representing 40 wetland and upland species. 
  • Placement of 90 habitat logs to provide perch areas for birds and habitat for amphibians and reptiles. 
  • Removing and replacing non-native hedgerow and old fence with 2,800 feet of wildlife friendly fencing. 

In the coming months, we will continue to seed and add additional native plants. The remaining acreage will continue to be farmed until the next phase is started, likely in 2025. 

This site is currently closed to the public.

About Amazon Prairie

Amazon Prairie is being restored as part of the City of Eugene’s wetland mitigation bank program. This program has been in place since 1995 and provides a sustainable solution for permitted projects that impact wetlands including commercial, residential, and industrial development. 

The wetlands we enhance or create here are used to offset those lost or impacted by development. This program is regulated through the Oregon Department of State Lands and the U.S. Army Corps of Engineers. The City must take several steps to remain in compliance with the rules governing wetland mitigation banking including detailed analysis, planning, and permitting.

The intention is to enhance or create a matrix of wet prairie, shallow ephemeral ponds, and upland prairie similar to the landscapes common in the Willamette Valley prior to Euro-American settlement and very rare today. It’s estimated that less than 5% of the original extent of this habitat remains. These habitats provide critical services including water storage, recharging of aquifers, carbon sequestration, removal of sediment and nutrients from stormwater run-off, and habitat for a wide range of plant and animal species including birds, mammals, amphibians, reptiles and insects (including valuable pollinators).
