Restoration of the Colorado Watershed, from the headwaters to the delta

Fred Phillips Consulting


The impaired headwaters of the Uncompaghre river and the parched floodplain of the Colorado Delta present unique restoration design challenges. Guided by three decades of lessons learned, the creation of diverse project teams, and the wisdom of our Elders (and water), two visionary stakeholder groups voluntarily take action to restore the river.

This chapter from The Codex of the Endangered Species Act, Volume II: The Next Fifty Years describes how genetic information is used to inform decision-making for the Endangered Species Act. In one section of this chapter (page 4 of the PDF, page 162 of the book), the use of genomics to differentiate between subspecies of willow flycatcher (Empidonax traillii) is described.

This article describes how researchers discovered that southwestern willow flycatchers in southern California have evolved in response to climate change. Southwestern willow flycatcher (SWFL) populations are threatened by climate change and habitat loss. By sequencing DNA from historical SWFL samples and comparing these to modern samples, researchers determined that modern SWFL were more likely to have beneficial genes that help them cope with changing climate.
