Restoring California's Wild Watersheds

Why more water for wildlife means more water for people.

Emboldened by that success, the small coalition of county officials and businessmen expanded to include ranchers, environmentalists, and state and federal officials. Although many of them had been at odds over land management issues, they realized they could only heal the watershed if they cooperated. Wilcox had been a firsthand witness to stream dredging and other practices harmful to ranchlands and forests. A man more at home in a pickup truck than an office, he was eager to be a part of reversing the damage. “I believe in watershed restoration. It has always been in my bones,” he says. And that became the Feather River coalition’s goal: restoring entire meadows along with the creeks flowing through them.

Now, as climate change is altering historic snowfall patterns, land managers are turning to meadows to help reduce the effects of a warming planet.

Among the methods they have pioneered is a low-tech procedure known as “pond and plug.” Crews with heavy equipment dig several of the channels wider and deeper, creating small ponds. They use the excavated dirt to fill the remaining gullies back to the original ground level. Along Red Clover Creek, the groundwater began rising almost immediately after the crews finished plugging the channels. By the following spring the ponds were flush with the water that would otherwise have raced downstream in late winter. Above and below the pond where Wilcox sits, the creek has found its way across the meadow in a natural, meandering channel.

The Feather River group has completed 66 restoration projects, which include 3,900 acres of meadow and

44 miles of stream. Since the work began, the data from a series of permanent monitoring stations show that the flow out of restored meadows is greater and lasts longer into the summer. Water temperatures have dropped despite an increase in average air temperatures, and stream turbidity, a measure of the amount of dirt and debris suspended in the water, has decreased to almost half pre-project levels. Groundwater, which never reached the surface before the restoration work, is now consistently at or above ground level for at least part of the year.

From Water to Wildlife

The Feather River projects have inspired the much larger Sierra-wide meadow restoration coordinated by the National Fish and Wildlife Foundation. Private landowners, universities, local and national resource organizations, and the U.S. Forest Service are working together to design strategies that will raise the water table and slow the flow out of mountain meadows. In an area from the Pit River in the north to the Kern River in the south, they are evaluating potential projects to determine which will yield the maximum benefits to fish and wildlife and the greatest quantities of water. Their goal is to restore at least 20,000 acres a year by 2014, says Male.

“Nationwide, we’re looking for tangible actions that address the realities of climate change. This is one of the best examples in America of a restoration initiative that can directly help people and wildlife adapt to our changing planet,” Male says.

The plan, over the first five years, calls for restoring 60,000 acres of meadow. As the water table rises and meadows soak up more water from melting snows, native habitat lost for decades should return. Among the endangered species expected to benefit are the yellow warbler, Yosemite toad, Lahontan cutthroat and golden trout, Townsend’s big-eared bat, and the Sierra Nevada red fox.

But the effects of widespread meadow restoration will also flow downstream to farmers and other water users. The Forest Service manages about half of the Sierra’s degraded meadowlands. The agency is determining which of the 11,700 separate meadows in 10 national forests need to be restored. All are located on streams important for water supply, says Barry Hill, a regional hydrologist. Using foundation funds, the Forest Service hopes to determine the amount of additional water available for downstream use once the meadows return to health.

The Sierra projects are unique among large-scale water restoration efforts in the United States because of their potential to increase the amount of water available in a river system, says Male. Comprehensive efforts to restore the Chesapeake Bay, the nation’s largest estuary, focus on improving the quality of water flows throughout the 64,000-square-mile region. In the Everglades, a wide-ranging plan to revive a dying ecosystem aims to improve the distribution of flows throughout 18,000 square miles in southern Florida. Along the lower Mississippi River and coastal Louisiana, the largest wetlands restoration effort is designed to reverse the pattern of land erosion by buffering against floods and hurricanes and, like all of the major projects, improving wildlife habitat.

Just how much more water healthy Sierra Nevada meadows can deliver is a matter of debate. Some scientists believe the boosts in stream flow may be absorbed by increases in vegetation in the new, restoration-created habitats. Others believe restoration could contribute up to 6.5 billion gallons of additional water storage throughout the California range. Over time, says Male, these restored meadows could hold 16 to 160 billion gallons of fresh water. That’s equal to the size of one of the new dams state officials have proposed for construction to offset the state’s declining snowpack.

Restoring mountain meadows will not solve California’s water crisis. That will take a collective commitment from the agriculture industry, from municipalities, and from everyone who depends on the Sierra snowmelt for their livelihoods and their lives. It will also require more political will than elected officials have traditionally marshaled. Wilcox believes the public recognizes the value of healthy watersheds. He is optimistic that stream restoration will become routine as more people understand its importance upstream and downstream.

Meanwhile, the benefits to wildlife are unequivocal. In the wet meadow surrounding Red Clover Creek, the number of waterfowl species has doubled since Wilcox and his crews completed the pond-and-plug project. He has seen buffleheads, gadwalls, and two species of teal breeding in early spring. Sandhill cranes, willow flycatchers and 10 other species on state and federal watch lists have returned to the area. Walking through Red Clover Valley from the pond, Wilcox bends down to study a clump of dancing hairgrass, one of a handful of plant types that have regenerated from seeds dormant in the soil for decades. He has yet to see elk but he has found their tracks—the first in the area in decades.
