EVERETT, Wash. -- Eelgrass plays a vital role in marine habitats, but along the West Coast, it's disappearing at alarming rates.

A new study found to restore seagrasses, it's more important to think about 'where' rather than 'how.' The report, commissioned by The Pew Charitable Trusts, analyzed 51 eelgrass restoration projects, including 14 in Washington state.

Kathryn Beheshti, California SeaGrant State Fellow for the California Ocean Protection Council and co-author of the report, said there are multiple restoration methods, and she expected that to be the most significant factor.

"What we found was that actually, restoration method, while important, is not the most important factor in predicting whether a restoration project will succeed; and that it's much more dependent on the environmental conditions and the site-specific conditions of a particular project," Beheshti outlined.

Researchers found about 30% of the world's eelgrass has disappeared since the 1870s, including a troubling case in California's Morro Bay, which has seen a 90% decrease in the last 15 years.

Beheshti said major causes of eelgrass decline are development and runoff pollution.

Eelgrass is found near shore and is considered a foundation species for ecosystems; other species, from sea otters to halibut, use it as habitat.

Melissa Ward, a post-doctoral researcher at San Diego State University and the report's other co-author, studies eelgrass's ability to combat climate change.

She said there's promising research that the plant is good at storing carbon. It also removes carbon dioxide from seawater, which is increasing in the ocean as more greenhouse gases are pumped into the atmosphere.

"It's becoming more and more important to keep eelgrass in the water, because it can elevate the pH and make the water less acidic," Ward explained. "So, the refuge that seagrasses provide may become more critical as we move forward, but at the same time, they're also threatened by climate change."

Ward added restoration is crucial work, but conservation is as well.

"While we do need to restore to try to get close to historic levels of eelgrass coverage, we also need to make sure that we don't lose what we already have," Ward urged.

A Wildlife Corridors Action Plan for New Mexico identifies 11 priority "safe passage" projects, such as underpasses and overpasses, to improve driver safety and connect more natural habitat for the state's native wildlife.

Garrett Vene Klasen, director of northern conservation for the New Mexico Wilderness Alliance, said the state has a high number of hot spots for wildlife-vehicle collisions, partly because climate change continues to compromise historic wildlife habitats.

"We're seeing all animals having to travel further for dependable food and water," he said. "Elk, deer and other wildlife are being drawn into urban areas because of food availability."

The Wildlife Corridors Action Plan is a joint project of the New Mexico Departments of Transportation and Game and Fish. Public comments about the plan are being taken through March 12. The draft and instructions for how to comment are online at wildlifeactionplan.nmdotprojects.org.

Vene Klasen admitted that the infrastructure needed is expensive, but said so is the damage to vehicles when they hit large animals - and the cost of human life can't be measured.

"I hit an elk last winter on my way to Taos, N.M., and it's a 600-pound animal - and it could have killed me," he said. "So, we need to create safe passage and corridors for them to move back and forth."

The New Mexico Legislature's current 30-day session is primarily devoted to budget issues. Vene Klasen said he believes the state should use its budget surplus to address the recommended projects identified in the report.

"We need to designate significant sums of money annually to address this really, really growing problem," he said. "This should be a priority of our legislators and the governor. This is serious stuff."

The federal Wildlife Crossings Pilot Program was included in the bipartisan infrastructure package signed into law last November.

A bill before the Michigan Legislature would allocate $2.4 billion dollars in federal funds for repairs to the state's aging water infrastructure.

It would make use of funds from the Infrastructure Investment and Jobs Act, as well as the American Rescue Plan, to improve the state's water supply, replacing old lead water lines, and repairing dams and residential sewer lines.

Tim Minotas, legislative and political coordinator for the Sierra Club's Michigan Chapter, noted most of Michigan's water infrastructure is between 50 and 100 years old.

"We are seeing massive flooding from extreme weather events, because our infrastructure cannot handle it," Minotas observed. "People's water is being contaminated from lead service lines, PFAS and other pollutants. We are also seeing raw sewage discharged into our rivers, lakes and streams."

The state Senate has passed the bill, and it's now up for a House vote. Minotas described the bill as a "great first step," but said even more could be done to get water infrastructure up to par. His group estimated Michigan should be spending more than $2 billion a year on drinking water, storm-water and sewer infrastructure needs.

Even after Flint's water crisis, places like Benton Harbor, a majority-Black city in southwest Michigan, are still facing lead-contaminated water, which has not been a concern in neighboring majority-white suburbs.

Minotas pointed out the bill could make a dent in disparities.

"This is really a reversal in the trend of disinvestment in drinking water, wastewater, stormwater infrastructure that we have seen here in Michigan for decades," Minotas argued. "This bill is a really good down-payment toward addressing our drinking and wastewater needs, especially in a time of climate change."

In addition to water infrastructure, he emphasized it is important for Michigan to prioritize making progress with electric vehicles, community solar and utility accountability, either through federal funds or legislation in Lansing.

Environmental advocates are in favor of investments in climate action and nature projects New York Gov. Kathy Hochul put forth in her executive budget.

Among the proposals is a $4 billion Environmental Bond Act - with projects geared toward protecting clean water, reducing pollution, and reducing local climate risks - and $400 million for the state Environment Protection Fund.

With implementing New York's Climate action plan at the forefront, Jessica Ottney Mahar - New York policy and strategy director with The Nature Conservancy - said her group hopes the Legislature will agree to make the proposed investments.

"Take a look at that climate plan, and really calibrate the future of the next few budgets to make sure that we're meeting the demand that it's going to take to change the way we're running New York," said Ottney Mahar, "from all different kinds of perspectives to achieve those goals."

The governor's budget also proposes $500 million for offshore wind manufacturing, $200 million for capital projects at state parks, $90 million in capital funding for the Department of Environmental Conservation and $500 million for clean-water projects.

The proposed budget will now be considered by the state Legislature. The final version is due March 31.

According to Ottney Mahar, the investments are an opportunity to merge environmental restoration and flood prevention.

"Thinking about how, as communities, we're relating to water," said Ottney Mahar, "making sure that we're restoring floodplains, the area that water will naturally flow and giving space for that water to move, and also restoring natural areas that can help us by absorbing water."

Hochul also has proposed an expansion of one million additional acres of freshwater wetlands to the state-protected areas.

Ottney Mahar said her group looks forward to working with Hochul to bring the initiatives to fruition.

"We're really excited to see her embracing the environment, and embracing the need to tackle climate change," said Ottney Mahar, "as we build a new era for New Yorkers and the next generation of New Yorkers."

Voters will still have to decide upon the proposed $4 billion Bond Act this November.
