In 2010, an explosion on the Deepwater Horizon oil rig made anoil-soaked pelican the prevailing symbol of the precarious relationship betwixt manufacture and the environment on Louisiana'southward Gulf Coast. But long before the rig pumped 200 million gallons of crude oil into the Gulf of Mexico—and nonetheless today—the people of southern Louisiana accept had another such symbol: Large, invasive, semi-aquatic rodents called nutria, which have been chewing up the marshes for decades.

A recent documentary, "Rodents of Unusual Size," which premiered on PBS before this year and isnow available on iTunes, explores the integration of nutria into Louisiana'due south Gulf Coast through a host of characters. The documentary features nutria hunters, trappers, enthusiasts, and pelt-dealers. Ane nutria control specialist named Michael and his hunting dog George W. Bush track nutria on a golf grade. Local New Orleans celebrities Kermit Ruffins, a musician, and Susan Spicer, a chef, each demonstrate how to melt their ain version of the rodent. And women from a company called Righteous Fur prepare for a fashion bear witness to demonstrate the sexiness of swamp rat.

The flick's primary protagonist, all the same, is a fisherman and trapper named Thomas Gonzalez, who participates in the state'south Coastwide Nutria Command Program, which has placed a $5 compensation on the rodent. Gonzalez lives on a shrinking patch of marsh in the customs of Delacroix Island, 30 miles southeast of New Orleans.

By doing battle with the nutria, at that place is the sense that Gonzalez is fighting to maintain his way of life. Just the precariousness of his situation also demonstrates the larger, unwieldy political, industrial, and ecology forces that the citizens of the region accept been at the mercy of for years—forces that the new documentary touches on, but doesn't explore in depth.

The excesses of the fur merchandise are function of a larger cycle, where littoral commercialization has come at an environmental cost. Fifty-fifty BP's Deepwater Horizon oil spill, for all its harm, doesn't capture the extent of the subtler daily degradation oil and gas companies have had on Louisiana's wetlands. For decades, lax regulations from Louisiana's Section of Natural Resources allowed the energy industry to dredge canals, drill wells, and extract oil. Between this industrialization and the furnishings of climatic change, southern Louisiana'southward situation is dire. Co-ordinate to the US Geological Survey, between 1985 and 2010, the state'south coast lost, on average,effectually a football field of wetlandsevery hour.

Mitigating the damage volition take more than a determined ring of rodent bounty hunters—it will crave a concerted effort by the state, and eventually the nation at large, to commit to restoring and protecting wetlands, rather than treating them equally collateral damage.

Native to South America, wild nutria established populations in Louisiana in the early 1940s after fur farms released the rodents intentionally, or the critters escaped. In the 1950s, the state encouraged the nutria to spread, to make up for the decline of the native muskrat population—the pelts of which were one time the master article of the local fur trade. The Louisiana Department of Wildlife and Fisheries (LDWF) argued nutria, "a docile and likable rodent," would be a "Godsend" for the land'southward economy. Whether or not anyone actually came to similar the large rodent, which, on average weighs around 14 pounds and has long orange buck teeth, LDWF was right well-nigh the economical benefaction: Between 1962 and 1982, hunters and trappers harvested an boilerplate ane.3 meg nutria each year in the Louisiana wetlands.

But a fur-marketplace crash in the 1980s removed the incentives for trappers and left the nutria population unchecked. Initially, the state tried to salvage the marsh from the growing hordes of nutria by marketing the rodent every bit a culinary detail, says Catherine Normand, a biologist at LDWF. The section enlisted celebrity chefs to create nutria recipes, and handed out samples at events along with stickers that read: "I ate nutria, and I liked information technology." But the optics proved too nifty a hurdle. "It didn't really have off," says Normand, "because people can't get over the fact that they have that long scaly tail that's very, uh, very much like what a rat has."

Post-obit the nutria'southward failed entry into the dining scene, LDWF tried another approach by replicating the conditions that had been keeping the nutria in check during the 60s and 70s. "They came upward with the idea of essentially creating an artificial fur market place," says Normand. LDWF placed a $v bounty on nutria and developed a system in which hunters and trappers sever the tails—which are distinctive from whatever other native mammals—and bring them to an assessor. Tails are also easier, Normand adds, to store in a freezer.

The control programme enrolls around 250 active participants—many of them sustaining themselves between angling and crabbing seasons, which have been greatly reduced thanks to both the BP spill and wetland loss—and aims to harvest 400,000 nutria each year. While the numbers fluctuate, Normand says the program has been quite successful in obtaining its goal of reducing nutria caused marsh damage. In 1999, earlier the program began, LDWF estimated that more than than 100,000 acres of wetlands had been damaged by nutria. In 2017, the approximate was less than 5,900 acres.

Nutria rip out the stitching of the vegetation in Louisiana's marshes, which allows the tides to hem the declension. The degradation is compounded: Without the root systems, when flooding occurs, and as sea levels rise from climate change, the marshes launder abroad. Considering the marshes human action as a buffer for hurricanes, the erosion allows storms to inflict more impairment—on both the local communities and the wetlands themselves.

Because of the nature of this damage, "Rodents of Unusual Size" frames the participation of nutria hunters like Gonzalez as not just pecuniary, but existential. As the promotional blurb for the film puts it, the bounty hunters are "hellbent on saving Louisiana earlier information technology dissolves beneath their anxiety. Information technology is human being vs. rodent. May the best mammal win." What the film briefly mentions, merely does not explore, are the broader causes of wetland loss in Louisiana, which get in beyond the appetites of a unmarried rodent. The film besides fails to spell out how attempts to commercialize and industrialize the declension threatened to destroy information technology.

While littoral degradation has happened, more than or less, at the same fourth dimension as the nutria expansion, there are multiple factors at play. "Nosotros've lost 1,900 square miles since 1932, when nosotros first started seeing the issues of land loss," says Jimmy Frederick, the communications director for the Coalition to Restore Coastal Louisiana, who points to several causes. The levee systems on the Mississippi River prevent necessary sediment from reaching the wetlands, which would normally restore the land. Oil and gas companies take dredged the canals, assuasive saltwater to move n into the wetlands and accelerating erosion. "When they were dredged, [the canals] may have been 50 feet wide, and at present they're three or four hundred feet wide," says Frederick. "Some of them have just turned into open water, and you can't even see where the canal was."

The extraction of oil and other minerals farther depletes the frail land. "In sum," wrote Oliver Houck, a law professor at Tulane Academy, in the Tulane Environmental Police force Journal in 2015, "oil and gas development had put Louisiana's littoral wetlands in a double bind, torn apart on top and undermined from below."

But as hunters are being put to work by the country to limit the harm caused past the nutria fur merchandise, former oil field workers may besides have the opportunity to rebuild the marshes destroyed, in part, by their sometime manufacture. In 2017, Louisiana presented its latest iteration of a Coastal Master Programme—an ambitious, $fifty billion effort to combat wetland loss that is primarily funded, for at present, with coin from fines related to the BP oil spill. Louisiana claims the plan could create up to 10,300 new jobs on the Gulf Coast. "In addition," the plan reads, "there is a proficient match betwixt the skills that this work demands and the skills of many south Louisiana workers who have feel in the energy sector."

Even with the chief plan, hopes of returning Louisiana'southward coast to its full natural glory have diminished. "What we're hoping for, and what the science indicates, is that we won't restore Louisiana'due south coast to what it once was," Frederick says. "Just we can slow [erosion] downwards enough so that we can build land, and lose less." To achieve fifty-fifty that moderated outcome, the programme will require federal taxation dollars—which it currently isn't receiving. "At some point that will take to change," Frederick says.

"If we are going to consummate this plan, we're going to have to convince the residuum of the country that Louisiana is worth saving."

While "Rodents of Unusual Size" may simplify the issues, in that location is a certain satisfaction that comes from projecting the circuitous interaction of geologic tendencies, global climatic change, corporate greed, governmental abdication, and lack of foresight onto a unmarried giant rodent. And the temptation goes across explaining wetland loss. At ane point in the documentary, Ruffins, the musician and apprentice nutria chef, drives around the Lower 9th Ward giving the filmmakers a tour of his old neighborhood. He hits a bump in the route. "Potholes in New Orleans," he says. "Probably the nutria."
