The specter of the Nice Salt Lake flooding is much from anybody's minds today, particularly after back-to-back years of record-setting low water ranges.
Nevertheless it was a special story within the Eighties. Consultants sought plans to pump out lake water to quell the danger of flooding because the lake threatened to hurt neighboring communities frequently. The floods that did happen not solely precipitated injury to surrounding cities and cities on the time, they in the end ushered in a totally new headache for the Nice Salt Lake ecosystem as soon as the water subsided.

The rising salty water killed off native vegetation that after surrounded the lake, and phragmites — an invasive reed species that may develop as much as 15 toes in peak — slipped in sooner or later and took over, mentioned Karin Kettenring, a professor of wetland ecology at Utah State College's School of Pure Sources.
"Phragmites is profitable as a result of it does nicely in disturbances, so meaning areas the place there may be numerous gentle and numerous the opposite crops have been eliminated," she explains. "So principally there was this huge space that was largely void of vegetation the place phragmites have been in a position to seed and develop. ... It may additionally deal with fairly salty circumstances."
Many years after the plant started to take over, consultants are nonetheless combating again.
Kettenring, one of many state's main phragmites consultants, helped collect a couple of dozen land managers, scientists, consultants and wetland fans to Farmington Bay on a current scorching, sunny September day for a area tour of one of many lake's ecosystems. The occasion served as a dialogue on what's working and what nonetheless must be executed within the effort to take away phragmites to allow them to get replaced with native crops.
It is a observe that has existed for nicely over a decade now, however a struggle that's removed from being over.
"We nonetheless see numerous mortality, numerous dying of the seeds and crops that we're placing on the market," she concedes.
The issue with phragmites
Phragmites are a Nice Salt Lake ecosystem troublemaker for a number of causes since rising within the Eighties. First, they produce hundreds of thousands of seeds, however these seeds actually aren't a supply of meals for a overwhelming majority of the estimated 10 million migratory birds that use the lake ecosystem yearly. Second, the species would not appeal to the forms of bugs that the birds feast on within the spring, both.
"It takes over the native vegetation that numerous the wildlife depends on in these wetlands for meals," says Chad Cranney, the division's assistant wildlife supervisor and the coordinator of the division's phragmites management program. "It is the meals they've grown up with for hundreds of years — hundreds of years — and phragmites has taken that stuff over."

It is a bodily barrier of types, too — dense and tall like a bamboo forest. This makes it a difficult plant for wildlife and other people to navigate via, whereas it additionally containers out any native species that do profit the ecosystem.
It may additionally take up "a good quantity of water" due to its dimension. That is doubtlessly as much as double the quantity of water native vegetation would possibly want, Kettenring provides. It is not an enormous issue within the lake's report low ranges, however it could possibly be one contributor to the issue. And because the lake dries, its means to thrive in disturbances is permitting it to take up house within the dried lakebed.
The plant species even alters the soil ranges to match its wants, Cranney factors out. A Utah State College examine printed earlier this 12 months additionally discovered that phragmites seed contained excessive concentrations of lead and mercury probably absorbed from toxins within the lakebed.
Lastly, all these phragmites seeds unfold virtually as quickly as dandelion seeds do, which can be how the species rapidly dominated the Nice Salt Lake ecosystem. Phragmites accounted for about 23,000 acres surrounding the lake by 2010. Kettenring says it is unclear how a lot the species accounts for now aside from the species may be very a lot part of the ecosystem immediately.
Briefly, it is a nightmare for the Nice Salt Lake ecosystem.
Combatting phragmites
Because of this consultants are combating again. The Utah Division of Wildlife Sources, for example, started a program in 2006 that seeks to take away as many phragmites crops as potential, although it has been a frightening activity given how rapidly the species can unfold in Utah's surroundings.
"We use each instrument we will in our toolbox, actually," Cranney says. "We go after this plant with herbicides, with hearth (and) by mechanical means — mowing it and rolling it. We additionally graze it with cattle and use totally different water administration methods, as nicely."

Different state and native businesses, in addition to academic establishments, nonprofit organizations and volunteer teams, have helped in newer years, particularly with the opposite rising troubles with the Nice Salt Lake. These businesses and organizations have retooled their strategies, as nicely.
Herbicides combined with techniques to chop down or take away lifeless inventory have emerged as the most effective practices in dealing with phragmites immediately, in response to Kettenring. This prevents hundreds of thousands of seeds from spreading whereas additionally eradicating the plant's bodily barrier within the ecosystem.
This month's area tour served as a bear in mind to maintain the struggle in opposition to phragmites going, particularly because the Nice Salt Lake struggles. It is a struggle that should occur yearly due to how prolific it might get in only one 12 months.
Future issues for native crops
But, even after eradicating phragmites, the hassle to revive native crops continues to be a battle. Hotter and drier summers, which has been the case in Utah over the previous 20 years, are making these efforts more and more tough, as are one of many greatest contributors to the Nice Salt Lake's demise: upstream water diversions.
Crops want water they usually merely don't get sufficient from the sky or the lake's tributaries due to upstream water diversions, particularly within the late summer season towards the tip of the irrigation season, Kettenring explains. That is main consultants to be artistic with their options.
"We're alternative ways to reintroduce these native species and attempting to have a look at issues like which crops do finest below these harsh circumstances, which of them can take care of the drought (and) which of them can compete in opposition to phragmites," she mentioned, pointing to pickleweed as one plant that has labored in locations.

These options do include their very own logistical difficulties. Native wetland seeds, for instance, aren't essentially straightforward to search out. The market might be costly too, particularly in comparison with rangeland seeding. The circumstances additionally must be good to plant, which means not too dry and never too moist. It will also be a battle to search out methods to distribute tons of seeds over huge marshy wetlands, Kettenring notes.
No matter all of the challenges, consultants say it is work they plan to maintain doing for years to return. They've welcomed the rising collaboration, assets and data which have emerged over the span of practically 20 years to deal with issues related to phragmites.
"It is fairly cool to see all these folks coming collectively attempting to be taught what must be executed and going on the market and really doing it," Cranney says. "It is a battle and it'll take much more time — though we have been engaged on this since 2006. We're simply going to must proceed to work on it."
