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.

Water begins flowing to create new wetlands at shrinking Salton Sea

Water began flowing from a pipe onto hundreds of acres of dry, sunbaked lake bed as California officials filled a complex of shallow ponds near the south shore of the Salton Sea in an effort to create wetlands that will provide habitat for fish and birds, and help control lung-damaging dust around the shrinking lake. The project represents the state’s largest effort to date to address the environmental problems plaguing the Salton Sea, which has been steadily retreating and leaving growing stretches of dusty lake bottom exposed to the desert winds. … The habitat area in Imperial County is being filled with water after an adjacent area called East Pond received its first water in April. In the coming weeks, state officials said the flooding of these sections will bring to fruition the first 2,000 acres of the Species Conservation Habitat Project, a central effort in California’s plan for improving conditions at the state’s largest lake.

California Tahoe Conservancy hosts public tours of restoration project at former Motel 6

The California Tahoe Conservancy let the public tour its latest restoration project at the former Motel 6 property in South Lake Tahoe Wednesday. According to the group, the portion of the Truckee River underneath the Motel 6 is the missing link between miles of marshland that feeds into Lake Tahoe, providing critical wetland habitat among other environmental benefits. “These wetlands provide a lot of really important functions. One of those is protecting and improving water quality by providing natural filtration,” Senior Environmental Scientist at the California Tahoe Conservancy Stuart Roll said. In addition to helping keep Tahoe blue, the marshland habitat is home to several ecosystems and wildlife. “Lots of species use these wetland, and so restoring them and improving them really helps biodiversity and ecosystems in Lake Tahoe,” Roll said.

Blog: Native turtles return to Yosemite after removal of invasive bullfrogs

The call of American bullfrogs was deafening when scientists from the University of California, Davis, first began researching the impact of invasive bullfrogs on native northwestern pond turtles at Yosemite National Park. … But the ponds of Yosemite sound different today, with a chorus of native species making themselves heard. The researchers’ study, published in the May issue of the journal Biological Conservation, found that as the park was depopulated of bullfrogs, northwestern pond turtles began to return. The study suggests that removing invasive bullfrogs may be necessary in priority conservation areas to help pond turtle populations recover.

Opinion: Restoring Mission Bay’s wetlands is a win-win for San Diego

City leaders face difficult tradeoffs as they navigate budget decisions. City tax revenue must cover essential services and infrastructure needs. At the same time, city government aims to fulfill legal obligations and environmental responsibilities, all while respecting the will of voters. Increasing Mission Bay’s vanishing wetlands uniquely meets all these criteria and constraints, using funds already earmarked by voters specifically for this purpose. San Diego voters passed Proposition C (2008) and Measure J (2016) creating a clear roadmap for Mission Bay Park Improvement Funds. Binding priorities in the City Charter Section 55.2 direct taxpayer investments first toward navigable waterways, then environmental restoration and protection, and last to deferred maintenance projects. These dedicated funds cannot be diverted to address any other citywide needs, no matter how pressing.

Volunteers planted 1,000 native plants at the Shank Alamo Wetlands east of Brawley during Community Climate Action Day on Saturday, May 17. According to event organizers, the native species will improve water quality, prevent erosion, and treat drainage water flowing into the Alamo River and eventually the Salton Sea. A coalition of state and national groups supported the event, including the Imperial Irrigation District, Keep California Beautiful, and the California Climate Action Corps. Robert Schettler, public information officer for the IID, said Boy Scouts, high school students, and local families volunteered to help get the plants in the ground. He said the turnout was larger than expected, with nearly 80 volunteers digging holes and planting 800 bulrushes and 200 cattails. The starter plants will grow over time and clean the water as it passes through the channels, Schettler said. “When you provide the Salton Sea with cleaner water, of course it’s better,” he said.

New California Law Bolsters Groundwater Recharge as Strategic Defense Against Climate Change

Groundwater recharge in Madera CountyA new but little-known change in California law designating aquifers as “natural infrastructure” promises to unleash a flood of public funding for projects that increase the state’s supply of groundwater.

The change is buried in a sweeping state budget-related law, enacted in July, that also makes it easier for property owners and water managers to divert floodwater for storage underground.

An intentionally flooded almond orchard in Tulare CountyIt was exactly the sort of deluge California groundwater agencies have been counting on to replenish their overworked aquifers.

The start of 2023 brought a parade of torrential Pacific storms to bone dry California. Snow piled up across the Sierra Nevada at a near-record pace while runoff from the foothills gushed into the Central Valley, swelling rivers over their banks and filling seasonal creeks for the first time in half a decade.    

Suddenly, water managers and farmers toiling in one of the state’s most groundwater-depleted regions had an opportunity to capture stormwater and bank it underground. Enterprising agencies diverted water from rushing rivers and creeks into manmade recharge basins or intentionally flooded orchards and farmland. Others snagged temporary permits from the state to pull from streams they ordinarily couldn’t touch.

SIDEBAR: Creating A Floodplain Buffet for Salmon Smolts

Biologists have designed a variety of unique experiments in the past decade to demonstrate the benefits that floodplains provide for small fish. Tracking studies have used acoustic tags to show that chinook salmon smolts with access to inundated fields are more likely than their river-bound cohorts to reach the Pacific Ocean. This is because the richness of floodplains offers a vital buffet of nourishment on which young salmon can capitalize, supercharging their growth and leading to bigger, stronger smolts.

Ultimately, dedicated flows of river water were brokered under cooperative efforts by the U.S. and Mexican governments.

The Salton Sea is a major nesting, wintering and stopover site for about 400 bird species. Out of sight and out of mind to most people, the Salton Sea in California’s far southeast corner has challenged policymakers and local agencies alike to save the desert lake from becoming a fetid, hyper-saline water body inhospitable to wildlife and surrounded by clouds of choking dust.
