Topic: Wetlands

Overview

Wetlands

Wetlands are among the most important ecosystems in the world. They produce high levels of oxygen, filter toxic chemicals out of water, reduce flooding and erosion and recharge groundwater. They also serve as critical habitat for wildlife, including a large percentage of plants and animals on California’s endangered species list.

As the state has grown into one of the world’s leading economies, Californians have developed and transformed the state’s marshes, swamps and tidal flats, losing as much as 90 percent of the original wetlands acreage—a greater percentage of loss than any other state in the nation.

While the conversion of wetlands has slowed, the loss in California is significant and it affects a range of factors from water quality to quality of life.

Wetlands still remain in every part of the state, with the greatest concentration in the Sacramento-San Joaquin Delta and its watershed, which includes the Central Valley. The Delta wetlands are especially important because they are part of the vast complex of waterways that provide two-thirds of California’s drinking water.

Shrinking wetlands have an impact on migratory birds in the Sacramento Valley, biologists say

Every winter, millions of migrating birds come to the Sacramento Valley, but now these birds may find the marshes and flooded rice fields dry. The marshes and flooded rice fields here are a stopping point for the birds along the Pacific flyway, and scientists are now putting GPS trackers on birds to learn how they’re reacting to the dry environment. “A migratory pathway for waterfowl and shorebirds that are coming from northern areas, moving into the Central Valley and looking for spots to feed, to rest and continue on their journey farther south to warmer areas in the winter, and then heading back north again in the spring,” Samantha Arthur, Audubon California Working Lands Program Director, said.

Blog: We must save fresh water to save ourselves

As the twin threats of climate change and biodiversity loss come to a head this decade, the fate of our fresh water lies in the balance. Extreme weather is becoming increasingly common, bringing massive rainfall and flooding in some regions and widespread heat and drought in others, with disastrous impacts on both humans and nature. At the same time, we have lost nearly a third of the world’s freshwater ecosystems and 83% of monitored freshwater species since 1970, a rate that is significantly higher than that of terrestrial and marine species in the same timeframe. Freshwater ecosystems deliver the water on which all life depends. The urgency to better protect them is now.

Salton Sea public health disaster gets a $250 million ’shot in the arm’

Last week, the federal government announced it will spend a quarter of a billion dollars over four years to clean up what remains of the Salton Sea, a lake in southern California that has been shrinking due to climate change-driven drought.  For decades, communities living near the sea have been afflicted by health problems caused by algae blooms and dust storms spurred by wind kicking up drying sediment from the sea’s ever-widening shores. The government’s new plan aims to help remediate some of those health impacts while simultaneously encouraging farms in the region to reduce their reliance on water from the Colorado River.

How the climate crisis is changing the Bay Area bird population

The San Francisco Bay is the largest estuary in Western North America and a key link in the 4,000-mile Pacific Flyway, one of the primary migratory routes used by birds to move north and south across the continent. It’s a place where birds come to rest and refuel for their long trip, or breed and nest the next generation. But in the span of a few human generations, 90% of California’s wetlands have disappeared to development and agriculture, endangering migrating and local birds. Now drought and sea level rise are further diminishing important bird habitats. As climate change becomes a bigger threat to the Bay Area’s local and migratory birds, scientists and conservationists work to help habitats adapt to climate change to ensure bird’s futures.

California’s Salton Sea to get $250 million in U.S. drought funding

The federal government said Monday it will spend $250 million over four years on environmental cleanup and restoration work around a drying Southern California lake that’s fed by the depleted Colorado River. The future of the Salton Sea — and who is financially responsible for it — has been a key issue in discussions over how to stave off a crisis in the Colorado River. The lake was formed in 1905 when the river overflowed, creating a resort destination that slowly morphed into an environmental disaster as water levels receded, exposing residents to harmful dust and reducing wildlife habitat. The lake is largely fed by runoff from farms in California’s Imperial Valley, who use Colorado River water to grow many of the nation’s winter vegetables as well as feed crops such as alfalfa.

How floating wetlands are helping to clean up urban waters

Five small islands roughly the size of backyard swimming pools float next to the concrete riverbank of Bubbly Creek, a stretch of the Chicago River named for the gas that once rose to the surface after stockyards dumped animal waste and byproducts into the waterway. Clumps of short, native grasses and plants, including sedges, swamp milkweed, and queen of the prairie, rise from a gravel-like material spread across each artificial island’s surface. A few rectangles cut from their middles hold bottomless baskets, structures that will, project designers hope, provide an attachment surface for freshwater mussels that once flourished in the river.

Blog: The troubled history—and uncertain future—of the Salton Sea

When an irrigation canal was breached in the early 1900s, the resulting flood created Southern California’s Salton Sea. It was a rare event that quickly created a beneficial presence in the Imperial Valley, as the lake provided recreation opportunities, tamped down dust, and became a stopover for birds on the Pacific Flyway. But now, with inflows declining, this hundred-year-old sea is drying up, and that’s having a host of negative consequences for wildlife and air quality in the region. We spoke with Kurt Schwabe—professor of public policy at the University of California, Riverside and adjunct fellow at the PPIC Water Policy Center—about some of the biggest issues facing the sea, as well as potential solutions.

By foot, horse, and canoe, European explorers centuries ago undertook years-long expeditions to document the length and breadth of major rivers. Today, satellites make the first pass of discovery. Though rivers meander and melting glaciers birth new lakes annually, the world’s major drainages have largely been mapped. Yet one fundamental dimension remains largely a mystery: the rise and fall of water bodies globally. Accurately measuring, at low-cost, the weekly changes in rivers, lakes, and wetlands would allow scientists to observe how much water moves through them. Land-based gauges do some of this work.

New research: Accumulation, transformation and transport of microplastics in estuarine fronts

Millions of tons of riverine plastic waste enter the ocean via estuaries annually. The plastics accumulate, fragment, mix and interact with organisms in these dynamic systems, but such processes have received limited attention relative to open-ocean sites. In this Perspective, we discuss the occurrence and convergence of microplastics at estuarine fronts, focusing on their interactions with physical, geochemical and biological processes. Microplastic transformation can be enhanced within frontal systems owing to strong turbulence and interactions with sediment and biological particles, exacerbating the potential ecosystem impacts. The formation of microplastic hotspots at estuarine fronts could be a target for future plastic pollution mitigation efforts.

As the Great Salt Lake continues to shrink to unprecedented levels, a key component of its landscape and food web is missing. The lake is known for thick, black clusters of brine flies by the billions, which pupate in its salty water then gather in dense mats to reproduce on shore. The insectile masses occasionally gross out beachgoers, but the bugs are harmless to humans. Crucially, they provide a nutrient-rich feast for millions of migrating birds. This year, however, the fly swarms are gone. And something’s off about the few bugs that remain. Scientists say it’s a sign the lake’s ecological demise is here.

Along the banks of the Sacramento-San Joaquin Delta in Oakley, about 50 miles southwest of Sacramento, is a park that harkens back to the days when the Delta lured Native Americans, Spanish explorers, French fur trappers, and later farmers to its abundant wildlife and rich soil.

That historical Delta was an enormous marsh linked to the two freshwater rivers entering from the north and south, and tidal flows coming from the San Francisco Bay. After the Gold Rush, settlers began building levees and farms, changing the landscape and altering the habitat.

Two Countries, One River: Crafting a New Agreement
Fall 2016

As vital as the Colorado River is to the United States and Mexico, so is the ongoing process by which the two countries develop unique agreements to better manage the river and balance future competing needs.

The prospect is challenging. The river is over allocated as urban areas and farmers seek to stretch every drop of their respective supplies. Since a historic treaty between the two countries was signed in 1944, the United States and Mexico have periodically added a series of arrangements to the treaty called minutes that aim to strengthen the binational ties while addressing important water supply, water quality and environmental concerns.

Water on the Edge (60-minute DVD)

Water truly has shaped California into the great state it is today. And if it is water that made California great, it’s the fight over – and with – water that also makes it so critically important. In efforts to remap California’s circulatory system, there have been some critical events that had a profound impact on California’s water history. These turning points not only forced a re-evaluation of water, but continue to impact the lives of every Californian. This 2005 PBS documentary offers a historical and current look at the major water issues that shaped the state we know today. Includes a 12-page viewer’s guide with background information, historic timeline and a teacher’s lesson.

Pacific Flyway

The Pacific Flyway is one of four major North American migration routes for birds, especially waterfowl, and extends from Alaska and Canada, through California, to Mexico and South America. Each year, birds follow ancestral patterns as they travel the flyway on their annual north-south migration. Along the way, they need stopover sites such as wetlands with suitable habitat and food supplies. In California, 90 percent of historic wetlands have been lost.
