Culebra Island, located near Puerto Rico, boasts diverse marine ecosystems with extensive coral reefs protected by various reserves. Despite their ecological importance, these reefs face numerous threats such as pollution, rising sea temperatures, and coastal development. Efforts to monitor and conserve these habitats include NASA’s OCEANOS program, which engages students in marine research and coral restoration.

It is somewhat of a challenge to reach Culebra Island’s remote location, about 17 miles (27 kilometers) east of Puerto Rico. But those who do make it there find an array of marine ecosystems—including extensive coral reef areas protected by Culebra National Wildlife Refuge, the Luis Peña Channel Natural Reserve, and other conservation measures.

The Vital Role of Coral Reefs

Coral reefs are sometimes called the “rainforests of the sea” because of the diversity of marine life found amidst their formations. Corals build up slowly over time from the calcium carbonate secretions of small organisms called polyps. While coral reefs cover less than 1 percent of the ocean floor, scientists estimate that nearly 25 percent of all ocean species spend at least part of their lives in or near them, often depending on the structures for food, shelter, and protection.

Culebra Coral Reef

The remote archipelago is flanked by extensive coral reef areas, but these hubs of biodiversity face a summer of sweltering water temperatures.

Reefs around the world face a variety of environmental threats, including coastal development, overfishing, disease, tourism, and increasingly warm and acidic waters. To thrive, corals require clear water within a narrow temperature range that’s free of pollution and sunlight-blocking sediment.

How the Return of Salmon to the Klamath River Shows Us What’s Possible in Wildlife Conservation

Once a tragic example of degraded wildlife habitat, the Klamath River’s dam removal demonstrates how people can halt the decline of, and even restore, wildlife

November 26, 20244 min readHow the Return of Salmon to the Klamath River Shows Us What’s Possible in Wildlife ConservationOnce a tragic example of degraded wildlife habitat, the Klamath River’s dam removal demonstrates how people can halt the decline of, and even restore, wildlifeBy Jeff OppermanThe removal of the earthen Iron Gate Dam at the Klamath River in its final phase on August 14, 2024 in Hornbrook, California. Gina Ferazzi/Los Angeles Times via Getty ImagesImagine standing on a riverbank as thousands of dead salmon float past, belly-up and rotting in the hot California air. That's the sight—and smell—that greeted people along the Klamath River in September 2002, when 35,000 fish perished there in the span of a few days. They were victims of warm water temperatures and low river levels, both caused by dams and diversions that altered the river’s flow.This dramatic loss isn’t unique: according to October’s 2024 Living Planet Report, of which I was a co-author, wildlife populations monitored around the world have declined on average by 73 percent in just the last half century. Freshwater species like salmon have suffered even greater losses. Farming and development, like dams, in natural habitats have driven these declines.But the Klamath story continues to be written. Just a little over two decades on from the massive fish kill, the Klamath became the site of the largest dam removal project in history. Since removal of the lower four dams on the river was completed last month, salmon have surged upstream to parts of the river where they haven’t been seen for more than a century.

By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.No longer is the Klamath River a tragic example of the global nature crisis; instead, its restoration serves as an inspiring story of how people can work together to repair wildlife habitats. This huge turnaround was made possible through collaboration and unwavering commitment—especially by the region’s Indigenous people. It is an example we can learn from and start replicating across the world.The scale of that global need for restoration is daunting. The alarming results in the Living Planet Report are derived from the Living Planet Index (LPI), a set of statistics developed by the Zoological Society of London. The LPI provides a broad view of wildlife health across the planet, drawing on data from nearly 35,000 populations of birds, mammals, fish, reptiles and amphibians, across more than 5,000 species. It can also be used to track specific groups, such as migratory fish—from tiny gobies to giant catfish—which have experienced a staggering 81 percent decline since 1970.Halting—and then reversing—the alarming downward trends in fish and other wildlife populations will require major shifts in how we produce energy and food, and how we implement conservation. The Klamath shows that those shifts are within reach.Biologists capture juvenile Coho salmon, Chinook salmon and steelhead trout in Wooley Creek, a tributary to the Salmon River which is one of the largest tributaries to the Klamath River on August 15, 2024. The Coho and Chinook are tagged with a monitoring device and also fin clipped for a genetic study.Gina Ferazzi/Los Angeles Times via Getty ImagesThe Klamath was once the third most productive river for salmon on the west coast of the United States. Its migratory fish were the primary food—and central to the culture—of the Karuk, Yurok, Klamath and other tribes. But, beginning in the 1920s, four hydropower dams were built on the river, blocking salmon from swimming upstream to spawn and limiting them to a reduced stretch of the river. The expansion of irrigated farming further stressed the salmon through reduced flows and high water temperatures—the factors that caused the 2002 fish kill—and the runoff of chemicals and nutrients.But from that low point, the opening for recovery emerged. At the heart of the Klamath’s stunning turnaround was the unwavering dedication of the tribes to restore their salmon. Their long-neglected legal rights, cultural commitment, and steadfast efforts made river restoration possible. Collectively, their breakthroughs demonstrate that implementing conservation at the scale necessary to restore wildlife will require a diversity of both leadership and strategy.A man rides past an "Undam the Klamath" mural on the Orleans Market on Wednesday, Aug. 16, 2023 in Orleans, CA.Brian van der Brug/Los Angeles Times via Getty ImagesFirst, regulators, conservation groups and tribes negotiated agreements with farmers to reduce agricultural runoff, improve water quality, and balance irrigation demands with water levels in the basin’s lakes and wetlands. That led to the Klamath Basin Restoration Agreement, signed in 2010. That agreement also set the stage for removal of the four hydropower dams, an outcome the tribes had been pursuing for decades.Another catalyst for removal was the legal requirement that the owner of the dams, PacifiCorp, renew the dams’ licenses, which were set to expire in 2006. In the U.S., hydropower project owners must periodically apply for new licenses through a process that considers options for reducing the projects’ social and environmental impacts. For the Klamath dams, regulatory agencies recommended that license renewal would require the addition of fish ladders to allow salmon to swim above the dams— construction projects that would have been prohibitively expensive. Ultimately PacifiCorp signed a settlement agreement with the tribes, agencies and conservation groups to remove the four dams, which started late last year.The removal of four hydroelectric dams may seem like a major loss of renewable energy. Thanks to California’s rapid expansion of wind and solar energy generation projects, however, the loss of the Klamath dams—which provided just 2 percent of PacifiCorp’s generation capacity—will be offset many times over. In fact, California’s new renewable capacity added during the dam removal process will be nearly 20 times greater than that of the Klamath dams.Restoration of the Klamath clearly demonstrates the potential for leadership and resource management by Indigenous people—whose lands encompass 40 percent of the world’s remaining natural areas—and whose efforts will be central to effective conservation in the 21st century.Further, restoration was only possible through a diverse set of strategies. For centuries, nature conservation has been synonymous with setting aside large tracts of land in national parks or wildlife refuges. The Klamath Basin encompasses six national wildlife refuges, two national parks, and wilderness areas—and approximately two thirds of the basin is in public land, mostly national forests. And yet the salmon—one of the basin’s most important environmental and cultural resources—still found themselves on the ropes. Restoring that resource required agreements on water use, agricultural management and dam removal to restore river connectivity.Just such examples are sorely needed. In November representatives from 196 countries wrapped up the United Nations Biodiversity Conference (COP16) in Colombia and, while some important agreements were reached, much of the work of setting targets and designing strategies for conserving and restoring nature remains to be done. Reversing the losses of wildlife worldwide will require a diverse set of strategies. Protected areas will remain important, but so will transformations in how we produce energy and food and implement conservation. And while “transformation” may sound daunting, the Klamath’s remarkable turnaround demonstrates that the recovery of nature remains in reach.This is an opinion and analysis article, and the views expressed by the author or authors are not necessarily those of Scientific American.

This Month in Conservation Science: Trojan Seahorses and ‘Vampire’ Birds

Journals this month looked at “fabulous but forgotten” ecosystems, hungry monkeys, roaming lions, lead-poisoned birds, and more — including a focus on microplastics. The post This Month in Conservation Science: Trojan Seahorses and ‘Vampire’ Birds appeared first on The Revelator.

When I worked for a major academic publisher in the early 2000s, Christmas came twice a year: once in December and once when the annual Journal Citation Reports came out. The JCR, published every year since 1975, ranks academic journals against each other. Each journal receives something called an “impact factor,” a calculation based on how many papers a journal publishes and how many times its papers are cited by subsequent research within two years. This is a very big deal in scientific circles. The higher the impact factor, the more readily the publisher can sell a journal to libraries and other institutions and the more likely the journal is to receive high-quality submissions. That, in turn, helps keep future impact factors high. It’s not a perfect system. Smaller journals — such as those from the Global South or those covering narrow topics — don’t get cited as often, so they may not receive a high impact factor. That doesn’t mean they don’t have an impact, though: Recent research found that these smaller, niche journals actually have a greater effect on policy — particularly when it comes to protecting endangered species. Meanwhile there are plenty of other ways to assess a journal’s impact. Media mentions are also a big deal, and many journals now publish statistics for each paper’s news links or social-media shares. It could be argued that nonscientific citations have a greater effect on policy and public perception than anything else. So let’s dive into those smaller journals and share the latest science from other conservation journals around the world. Below you’ll find more than three dozen papers that grabbed my attention in the past few weeks. They cover “vampire” birds, hungry monkeys, feral cats, roaming lions, the wildlife trade, and more. Most of the articles are open access, so they should be available to researchers (and any other interested readers) around the globe. Will they also shape policy? That remains to be seen, but some of these papers have only been downloaded a couple of hundred times as of this writing, so let’s give them a fighting chance. “Animal-borne sensors reveal high human impact on soundscapes near a critical sea turtle nesting beach” (Biological Conservation) “Are vehicle strikes causing millions of bee deaths per day on western United States roads?

Biden administration offers alternatives for Colorado River’s long-term operations

Biden administration officials on Wednesday announced several potential alternatives for the Colorado River's long-term management, as the expiration date for the current rules approaches. The five alternatives will be considered as possible replacements for the 2007 Interim Guidelines for Lower Basin Shortages, which are valid through the end of 2026. These rules will steer conservation policies for a 1,450-mile river that provides water to about 40 million people in the U.S. and Mexico.  "We're in a moment for solutions and leadership,"  Acting Deputy Interior Secretary Laura Daniel-Davis said on a Wednesday press call. "Today, we're putting forth alternatives that have established a robust and fair framework for a basin-wide agreement." The Interior Department’s Bureau of Reclamation, which is overseeing the revisions in compliance with the National Environmental Policy Act (NEPA), had given Colorado River basin states an early March 2024 cutoff date for submitting a consensus-backed alternative themselves. The U.S. portion of the Colorado River region is split into a Lower and an Upper basin, which, respectively, include California, Arizona and Nevada, and Colorado, Wyoming, Utah and New Mexico.  Back in March, the two basins were unable to come to a unified agreement and ended up filing competing proposals for the river's long-term management. The Lower Basin states had agreed to reductions of their own while also placing an emphasis on shared cuts across the whole watershed — basing storage capacity totals not just on the massive Lake Powell and Lake Mead, but also on other smaller reservoirs in the Upper Basin. The Upper Basin states, on the other hand, submitted a plan that they felt would better reflect changing hydrological conditions in a region where water supplies come from mountain snowpack. In the absence of a March consensus, the federal government on Wednesday released its own alternatives, which will undergo extensive analysis in a forthcoming draft environmental impact statement (EIS). Those alternatives, according to the Interior Department, reflect elements proposed by basin states, tribes, cooperating agencies and non-governmental organizations. "We have laid the foundation to ensure that future guidelines and strategies will be sufficiently robust and adaptive to withstand the uncertainty of climate change impacts," Daniel-Davis said. The release of the proposed alternatives on Wednesday serves to facilitate a "timely development of final operating guidelines that will need to be in place by August of 2026," explained Bureau of Reclamation Commissioner Camille Touton, on the same press call.  Touton stressed that there are no preferred alternatives and that the options "represent a wide range of actions that provide improved predictability of water availability, enhanced opportunities for conservation and respond to a broad spectrum of hydrology." The proposals include four viable alternatives as well as a fifth "no action" alternative, which Touton explained is simply a NEPA requirement but would involve reverting to guidelines in place prior to 2007. Alternative 4, a "Basin Hybrid" plan, attempts to include portions of the plans submitted by the Upper Basin, Lower Basin and tribal nations. That option, according to the Interior Department, could help facilitate collaborative action among stakeholders.  In this proposal, Lake Powell releases would generally be based solely on the lake's elevation, but with some consideration of Lake Mead's levels. New delivery and storage mechanisms would serve both reservoirs, including conservation incentivization for both tribal and non-tribal parties.  This option would also make basin-wide cuts more equitable by spreading the burden, which has long been a priority of the Lower Basin states. Specifically, a portion of the reductions that the Lower Basin must make amid shortages would be based on a seven-reservoir capacity, rather than just that of Lake Powell and Lake Mead. Alternative 3, called "Cooperative Conservation," was informed by proposals from conservation organizations and would predicate Lake Powell releases upon total Upper Basin system storage and recent hydrological conditions, according to the Interior Department. Under this option, a large share of Lower Basin cutbacks would be based on the seven-reservoir storage capacity, recent hydrology and voluntary contributions from the two basins. In Alternative 2, called the "Federal Authorities Hybrid," Lake Powell releases would be based on a combination of Lake Powell and Lake Mead elevations, hydrological records and Lower Basin deliveries. Shortage responsibilities under this plan would be triggered entirely by the combined seven-reservoir storage capacity and distributed proportionally among parties. A "Federal Authorities" option, Alternative 1, would provide "robust protection of critical infrastructure" within the federal government’s current statutory authorities. Lake Powell released would be based on Lake Powell's elevations, with Lower Basin shortages distributed based on the region's century-old water rights priority system. "These alternatives represent a responsible range from which to build the best and most robust path forward for the basin," Touton said. "There certainly are extremely difficult choices and tradeoffs to be made, but we believe that there are ample opportunities to create a fair path to solutions that work for the entire region." In addition to presenting the alternatives, the Biden administration officials also devoted ample time in the Wednesday press call commending the progress made under President Biden on Colorado River issues. Daniel-Davis recalled how "in 2021, impacts of a historic drought in the West brought the Colorado River Basin and the communities it serves to a near crisis," stressing how Lake Mead and Lake Powell plunged to critically low elevations. But she touted the administration's "all-of-government approach" and "really bold and decisive action" for helping solve the crisis.  Touton offered a similar perspective, adding, "We were able to bring the Colorado River into the back in the break of the worst drought in 1,800 years." White House National Climate Advisor Ali Zaidi, credited not only the administration, but also the region's bipartisan partners for bringing "the river back from the brink." He commended U.S. West governors by name, and from both sides of the aisle, for their work on natural resource conservation and for recognizing the strain on the Colorado River system. Zaidi described the alternatives as "a playbook to come together once again, to meet the urgent need of stabilizing situation beyond 2026." In response to the Interior Department's publication of alternatives, JB Hamby, Colorado River commissioner for California, said in a statement that "federal law requires the Colorado River Basin’s reservoirs be managed in accordance with the Colorado River Compact." The most significant components of that 1922 water agreement, Hamby stated, are "mandatory deliveries of water from the Upper Basin to the Lower Basin and Mexico." "In order to be valid, any alternative considered must meet this requirement unless the states agree to a compromise otherwise," he said. Becky Mitchell, Colorado River commissioner for the state of Colorado, said in a statement her state did not have specific comments on the alternatives "at this time." "Colorado continues to stand firmly behind the Upper Division States’ Alternative," she said, noting that this proposal is supply-driven and aims to boost Lake Powell and Lake Mead while protecting Colorado's "significant rights and interests" in the river. "Colorado remains committed to working collaboratively with the other Basin States, the federal government and tribal Nations towards a consensus approach and also stands ready to protect our State’s significant interests in the Colorado River," Mitchell added. In a separate press call following the Interior Department's announcement, Tom Buschatzke, director of the Arizona Department of Water Resources, told reporters that he needed "a lot more time to digest all this." While he noted "some really positive elements to these alternatives," he also said that he was "disappointed that Reclamation chose to create alternatives, rather than to model the Lower Basin state alternative in its entirety." "It didn't start at one extreme or the other, and it showed unequivocally that the Lower Basin was willing to take the first tranche of cuts," Buschatzke added.

Second Teen Charged in New Jersey Forest Fire as Rain Should Help Douse New York Blaze

A second teenager has been charged with intentionally setting a wildfire in a New Jersey suburb of Philadelphia

A second teenager was charged with intentionally setting a wildfire in a New Jersey suburb of Philadelphia as “significant” rainfall was expected to help douse a stubborn wildfire burning on the New Jersey-New York border Wednesday.Many parts of the Northeast have been under red flag alerts, with firefighters responding to hundreds of brush fires in tinder-dry and windy conditions. Officials have said numerous prolonged rain storms are needed in parts of New England as well as New Jersey and New York, which are the driest in between 120 to 150 years.Police in Evesham Township said Wednesday they have arrested a 14-year-old from Marlton in connection with an Oct. 30 wildfire that burned less than a tenth of a square mile. On Nov. 7, they charged another youth, also from Marlton, with setting that same fire. The latest arrest was made Tuesday and announced on Wednesday. Both are charged with aggravated arson, and causing or risking widespread injury or damage.Both have been taken to a juvenile detention center as detectives investigate whether they might have been responsible for a second wildfire in Evesham a week later that burned a slightly larger area.A storm moving into the New Jersey-New York area Wednesday was expected to bring what New York officials called “significant” rainfall to the area of the Jennings Creek wildfire, which has burned 8.3 square miles and was 90% contained as of Wednesday morning.While that will undoubtedly help fire crews douse the fire, which is burning in several hard-to-reach areas of rugged terrain, the rain could bring its own challenges.“Soil within the burned area will become unstable and erosive as it becomes more saturated,” the New York Department of Environmental Conservation said in a statement Tuesday night. “Residents may see burned and decomposing trees fall within the fire area. A combination of mud and burned debris may run off into local waterways causing discoloration.”Two smaller wildfires in New Jersey, each having burned less than a tenth of a square mile, were declared fully contained Wednesday morning. They were burning in Hainesport in Burlington County, and in Pine Park in Lakewood in Ocean County.Follow Wayne Parry on X at www.twitter.com/WayneParryAC Copyright 2024 The Associated Press.
