I used to live in a hilly, temperate corner of the American west, right near the banks of a meandering river. On late-evening walks with my two dogs, I would routinely encounter all manner of economy-size mammalian wildlife: skunks, raccoons, opossums, coyotes. Sightings of a mountain lion in the area had occurred more than once, though my dogs and I were perfectly happy never to have chanced upon him. During the day, it wasn't unusual to see red-tailed hawks or turkey vultures circling overhead, or rigid V-formations of migrating Canada geese, or even the occasional egret or blue heron swooping down as it made its descent to its riparian home.
Oh, wait, I left out an important detail: My dogs and I were walking in the heart of Los Angeles—within earshot of the considerable traffic noise emanating from the I-5 Freeway, about 15 minutes from downtown as the crow (or the turkey vulture) flies. We were proximate, too, to Griffith Park, which at more than eight square miles is one of the largest urban parks of its kind, as well as one of the least developed. Our local mountain lion, the rather ignobly named P-22, called Griffith Park home; he's still there, in fact, roaming the hills and doing what mountain lions do, minding his own carnivorous business while largely (if not totally) steering clear of awkward interactions with humans and the built environment.
I couldn't help but think of P-22, and of my old wild stomping ground, when I learned that researchers from the National Park Service had recently installed cameras along 30 miles of the Los Angeles River and its tributaries. The LA River Wildlife Camera Project aims to document the abundance of fauna skulking, skittering and waddling along this waterway, to better understand their relationship to the river and—importantly—to increase public awareness of urban wildlife, in hopes of reducing instances of human-animal conflict.
Los Angeles is far from unique as an urban haven for unexpected forms of wildlife. Berlin is currently home to more than 3,000 wild boars, which unabashedly forage in parks and front yards. In Mumbai, one of the world's most densely populated cities, more than 40 leopards wander the streets in and around Sanjay Gandhi National Park, often applying their instinctive predatory skills to the city's sizable population of feral dogs. Coyote sightings are becoming more and more common in New York and Chicago. In March, John McPhee, the longtime New Yorker contributor, wrote colorfully of his fascination with the estimated 2,500 black bears that live (and sometimes steal cupcakes out of parked cars) in his home state of New Jersey. If you've ever visited Austin, Texas, and not been bitten by a mosquito, you can thank the 1.5 million Mexican free-tailed bats that live beneath the Congress Avenue Bridge downtown.
As our civilization encroaches further and further into wildlife habitat, we find ourselves sharing space with more and more creatures that we don't expect to find in our midst. But to paraphrase one commenter to a YouTube video featuring a mama bear and her cubs frolicking in a backyard swimming pool: They're not in our backyards, we're in their front yards. When we build on wildlife habitat, the land doesn't suddenly become "ours" and no longer "theirs." It becomes shared. And as the most recent arrivals, we humans have an obligation—a moral and ecological imperative, you might even say—to understand the ways, habits and needs of the communities that we're asking to join.

In Los Angeles, the LA River Wildlife Camera Project is being conducted in partnership with the larger Urban Wildlife Information Network, a Chicago-based consortium of scientists and researchers dedicated to helping cities "understand the ecology and behavior of their own wildlife species ... why animals in different cities behave differently, and what patterns hold true around the world." Images of animals caught on camera will be uploaded to Zooniverse, a platform for crowdsourced research where volunteers can share ideas and engage in citizen-science scholarship, which often proves to be of immense value to academic researchers.
The LA River, an ecologically vital yet troubled waterway, is a prime subject for such study. At 51 miles long, the river begins in the San Fernando Valley north of the city and winds its way through neighborhoods industrial, residential and semi-rural before finally emptying into the Pacific Ocean at Long Beach. Environmentalists, political leaders, scientists and civil engineers recently embarked on an ambitious plan to restore it, a major component of which will entail reconnecting the channelized waterway to its historic tributaries, wetlands and floodplains—i.e., to historic wildlife habitat. Initiatives like the Camera Project have the potential to spur public support and private funding, because through compelling photographic evidence, the essential relationships among local people, local resources, and local wildlife are made clear.
As I learned on those late-night walks with my dogs: You're never really alone in the big city, even when there are no other people around. The more we learn about the animals within our shared communities, the more we learn about what they—and we—need in order to coexist harmoniously and sustainably. And that's about as good a definition of neighborliness as you're ever likely to come across.

The conclusion to decades of work to remove a dam on the Middle Fork Nooksack River east of Bellingham, Washington began with a bang yesterday as crews breached the dam with a carefully planned detonation. This explosive denouement is also a beginning.
The History<p>The Middle Fork Nooksack drains glacier-fed headwater streams that run off the icy summit of 10,778-foot Mt. Baker. The Middle Fork joins the North Fork and then the mainstem of the Nooksack River, which travels to Bellingham Bay and Puget Sound. The entire Nooksack watershed stretches 830 square miles across Washington and into British Columbia.</p>
A Plan Comes Together<p>The Middle Fork dam is not a pool dam built for water storage. Much of the time, water flows over the top until dam operators drop a floodgate to divert water to new locations. That water travels about 14 miles through tunnel and pipeline to Mirror Lake, then Anderson Creek, and to Lake Whatcom before finally being delivered to residents' taps.</p><p>Before removing the dam, engineers had to move the water intake 700 feet upstream and situate it at an elevation that still enabled city water withdrawals throughout the year, regardless of flow conditions.</p><p>They also needed to make sure that the rushing water didn't sweep up fish and accidentally send them through the water-supply system.</p><p>"The solution required a fairly complex design in the intake structure, including a fish exit pipe out of that structure to put fish back into the river in a way that meets current environmental permit standards," explains LaCroix.</p>
Project layout for the removal of the Middle Fork Nooksack diversion dam and rebuilding of water intake. City of Bellingham<p>Despite the cost and the work, she says, being able to continue to meet their municipal water obligations while opening up habitat for threatened species has been a win-win.</p><p>"I think there's a lot of benefits to having a dam removal versus fish passage — the main one being that you get a free-flowing river that can be a dynamic ecosystem and change over time," she says. "A static fish ladder just can't provide that same level of ecosystem benefit."</p>
Restoration Success<p>Despite local authorities' championing dam removal on the Middle Fork, the project has largely flown under the radar, overshadowed in the Pacific Northwest by heated discussions about a much larger potential project — removing <a href="https://www.seattletimes.com/seattle-news/feds-reject-removal-of-4-snake-river-dams-in-key-report/" target="_blank">four federal hydroelectric dams on the lower Snake River</a>, a major tributary of the Columbia River.</p><p>Proponents of dam removal there see it as the best chance for recovering threatened salmon populations, including Chinook, which could help starving Southern Resident killer whales. Those dams also provide irrigation water, barge navigation and hydropower, so there's been more pushback against removal efforts.</p><p>Previous dam removals around the country, however, have proved successful at aiding fish recovery and river restoration.</p><p>Most notably the 1999 demolition of <a href="https://therevelator.org/edwards-dam-removal/" target="_blank">Edwards Dam on Maine's Kennebec River</a> restored the annual run of alewives, a type of herring essential to the food web. The fish run has gone from zero to 5 million in the two decades since dam removal. Blueback herring, striped bass, sturgeon and shad have also extended their reach. And the resurgence has brought back osprey, bald eagles and other wildlife, too.</p><p>The overwhelming success of river restoration on the Kennebec helped to spur a nationwide dam removal movement that's now seen 1,200 dams come down since 1999. Last year a record <a href="https://www.americanrivers.org/conservation-resource/a-record-26-states-removed-dams-in-2019/" target="_blank">90 dams</a> were removed in 26 states, including <a href="https://therevelator.org/cleveland-forest-dam-removal/" target="_blank">20 dams in California's Cleveland National Forest</a>.</p>
Spider excavators remove on dam on San Juan Creek in California's Cleveland National Forest. Julie Donnell, USFS<p>The results have been seen in the Pacific Northwest, as well, which boasts the largest dam removal thus far in the country. In 2011 and 2014, the demolition of <a href="https://therevelator.org/elwha-dam-removal/" target="_blank">two dams</a> on Elwha River, which runs through Washington's Olympic National Park, opened up 70 miles of habitat that had been blocked for a century. Scientists have started seeing all five species of salmon native to the river coming back, particularly Chinook and coho. Bull trout, they've observed, have increased in size since the dams were removal.</p>
Benefits on the Middle Fork Nooksack<p>McEwan hopes to see a similar outcome on the Middle Fork.</p><p>Like the Elwha the Middle Fork Nooksack is a relatively pristine river with little development, and dam removal is expected to provide a big boost to fish. The additional miles of spawning habitat are important, but so is the temperature of that water.</p><p>The dam removal will open access to cold upstream waters, which are ideal for salmon and getting harder to come by as climate change warms waters and reduces mountain runoff.</p><p>"This is really great for the climate change resiliency for these species," says McEwan.</p><p>Steelhead will get back 45% of their historic habitat in the river, and scientists expect Chinook populations to increase in abundance by 31%.</p><p>That <em>could</em> help Southern Resident killer whales.</p><p>"When you get to the ocean, it's a little bit of a black box in terms of what you can model and say definitively is going to help, but more fish is better for orcas," McEwan says.</p><p>Upstream habitat will see benefits, too.</p><p>Oceangoing fish like salmon enrich their bodies with carbon and nitrogen while at sea. When they return to their natal rivers to spawn and die, the marine-derived nutrients they carry back upriver become important food and fertilizer for both riverine and terrestrial ecosystems — aiding everything from trees to birds to bears.</p><p>"Once the fish start making their way back, it will start changing the whole ecological system," says Delgado.</p><p><span></span>But any ecological benefit from salmon restoration, either in the ocean or the upper watershed, won't be immediate.<br></p><p>"The population of salmon on the Middle Fork is so low that we expect it's going to take quite a while to rebound," she says. "But the big picture is that what's good for salmon is good for the region — our history and our destiny are intricately intertwined."</p><p>After decades of work, that process of restoration has finally begun.</p>

It can grow to a maximum of six inches (16 centimeters), change color depending on mood and habitat, and, like all seahorses, the White's seahorse male gestates its young. But this tiny snouted fish is under threat.
Building an Ocean Seahorse Destination<p>Seahorses are found in tropical and temperate coastal water worldwide, but are most abundant around Australia, China and the Philippines. </p><p>Trade in the tiny creatures is strictly regulated because of their use in traditional medicine, aquariums and their sale as dried curios. But because they are poor swimmers and cannot easily move elsewhere, habitat loss is a particular threat for these curious animals. </p><p>Seahorses wrap their tails around seagrass and corals to avoid being carried away on currents. They use the habitat to spawn and hide from predators such as crabs, while also feeding on riches of plankton and small crustaceans living in the reef.</p><p><span></span>Where corals aren't available, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.1217" target="_blank">scientists</a> found seahorses taking up residence in fishing nets and old crab traps abandoned at the bottom of the ocean. </p>
Mixing With the Locals<p>Baby seahorse mortality is high in the wild because they are easily caught, so those bred in the protected environment of the aquarium weren't ready to be released into the wild until early May.</p><p>The team released 90 new arrivals into Sydney Harbor, placing some directly into the purpose-built hotels, and others onto a net that wild seahorses had already settled on.</p><p>Before setting them free, the researchers marked each young seahorse with a fluorescent tag with unique IDs inserted just beneath the skin to track how they get on in the different environments. </p><p>"The most exciting part was being able to put these animals into the wild and then go back a month later and still see them surviving and growing," said McCracken. </p><p>The seahorses will be old enough to mate and reproduce around October or November 2020. And researchers hope that by then, they will be able to breed with the wild population. </p>
Building a Global Seahorse Hotel Chain<p>With seahorses everywhere facing the loss of their coral reef homes, similar projects have sprung up in places like Greece and South Africa, home to the world's most endangered seahorse, the Knysna seahorse. </p><p>"The endangered South African seahorse is benefiting from something quite similar, even though it wasn't intentional," said Peter Teske, professor at the Department of Zoology, University of Johannesburg.</p><p>In the South African <a href="https://www.researchgate.net/publication/322649251_An_endangered_seahorse_selectively_chooses_an_artificial_structure" target="_blank">case</a>, seahorses have bedded down in "Reno mattresses" — wire cages filled with rocks — that were used to build a new marina. Researchers from NGO Knysna Basin Project found the structures acted as a refuge for the animals.<span></span></p><p><span></span>While Teske describes the seahorse hotels as "a positive news story" and a great way to create public awareness of conservation, he added that establishing artificial habitats in some areas will only prevent the extinction of local populations.</p><p>"For a complete recovery, it is necessary to give the natural habitat a chance to regenerate," said the seahorse expert. </p>
Underwater Mascot<p>In Australia, the researchers hope the project could provide an opportunity to raise awareness not only of the plight of the Sydney seahorses but the other animals with which it shares its ocean habitat.</p><p>The waters around Sydney and the east coast are rich in biodiversity and include several threatened species like the weedy seadragon — a relative of the seahorse — and the grey nurse shark. Like the seahorse, they're also under pressure from pollution, ocean traffic and habitat loss through storms and coastal construction. </p><p>"It's a good thing to get people's support and interest. The seahorses are a useful vehicle to get people concerned if the harbor is in trouble," said David Booth, professor of marine ecology at the University of Technology Sydney who is also working on the project. </p><p>The hotels have become an attraction for divers hoping to catch a glimpse of these small but near mythical creatures. </p><p>"Everyone loves seahorses," added Booth, "they are so popular." </p>
