Will the Colorado River Delta Pulse Flow Make it to the Sea?

One of the big unknowns of the pulse flow of water currently working its way down the channel of the Colorado River in its delta is whether that water will reach the sea.  The mouth of the Colorado River drained historically into the Upper Gulf of California (Sea of Cortez), a unique body of water…

Chasing the Historic “Pulse Flow” Through the Colorado River Delta

For one week now, the Colorado River has been flowing into its delta.  It’s the first ever deliberate release of water here to benefit the environment. That the river is flowing again in its delta is somewhat astounding, all the more remarkable because it’s happening as the result of cooperation between the United States and…

Killing Sprees of a Mother Lioness

It was one of those eerily beautiful winter mornings in Central Mozambique.

Helena (a…

Twenty Five Years Reconstructing an Island Ecosystem

Islands are delicate ecosystems. Although less than 5% of the world’s land area, they are home to over 20% of the planet’s terrestrial biodiversity. In the last 500 years 80% of vertebrate extinctions have been on islands. Restoring an island ecosystem to its original state requires first unpacking the ecosystem of invasive species such as…

A Red List for Ecosystems: Will it Aid Conservation?

The most devastated ecosystem I’ve ever seen is the Aral Sea in Central Asia. Once the world’s fourth largest lake, the Aral spanned an area the size of Ireland. It harbored more than twenty species of fish, and its fishery sustained an annual catch of 44,000 tons and 60,000 jobs. Lush wetlands along the lake’s…

Returning the Colorado River to the Sea

This post is part of a series on the Colorado River Delta. Once teeming with life and spanning some two million acres, the delta of the Colorado River ranked among the planet’s greatest desert deltas. But more than half a century of damming and diverting the river’s flow to supply the burgeoning farms and cities…

The Mystery of the Migrating Fishes: Investigating Clues for Great Lakes Conservation Efforts

As a result, monitoring and maintaining the health of the Great Lakes ecosystem is an urgent priority. Of the diverse organisms inhabiting freshwater systems, fishes are familiar to scientists and laypeople…

Discovering the New White Salmon River: Paddling Through the Old Condit Dam Site

  There is a giant basalt rock just downstream of the former site of Condit Dam on Washington’s White Salmon River. When the dynamite blasted a hole in the base of the dam last October, I watched the flood of mud and reservoir water explode through the breach. I remember thinking, that rock has been…

Rafting the Free-flowing White Salmon River a Year After Condit Dam Fell

  It started with a blast last fall – 700 pounds of dynamite ripping through the base of the White Salmon River’s Condit Dam in western Washington State. Since then, crews have been dismantling the 125-foot tall concrete structure in a major effort to restore the river and its historic salmon and steelhead runs. Last…
