After reaching a document low in 2022, efficient administration and above-average snowpack helped elevate and maintain Nice Salt Lake water ranges. Sadly, in 2026, drought and below-average snowpack are once more threatening a return to historic lows. As the lake shrinks, the meals net that sustains thousands and thousands of birds begins to unravel. The wetlands that body its shores are additionally below stress from sustained drought, city progress, water diversions, and the relentless unfold of invasive vegetation. The window to behave—to guard what stays and restore what continues to be restorable—is narrowing.
Nationwide Audubon Society’s new report, the Great Salt Lake Birds and Habitat Assessment meets the urgency of this second. The science-based evaluation is designed to tell conservation methods throughout the Nice Salt Lake watershed and help Audubon’s strategic priorities, with its core objective specializing in defending birds and the locations they want, at this time and tomorrow.
Each spring and fall, one thing outstanding occurs over the northern Utah desert. The sky fills. Not with clouds, however with birds—thousands and thousands of them—wheeling, diving, resting on shimmering, salt-crusted mudflats. Wilson’s Phalaropes spin in tight circles on the water’s floor, creating small vortexes that pull invertebrates up from under. American Avocets wade within the shallow bays, skimming the floor with upturned payments. Eared Grebes arrive in waves so dense they appear to darken the open lake, gorging on brine shrimp earlier than they proceed their journeys to their wintering grounds. And each winter, when a lot of the continent’s waterbird inhabitants has funneled south, 1000’s of Frequent Goldeneye, Northern Pintail, and Tundra Swan linger within the bays and the wetlands of the Nice Salt Lake basin, discovering open water and meals in a panorama that might in any other case supply little.
However Nice Salt Lake can also be a spot the place birds dwell. The biggest breeding colony of American White Pelican within the western United States nests on rocky islands inside the lake itself. Snowy Plovers scrape nests into the sunbaked sediment of huge playas. White-faced Ibis nest by the tens of 1000’s within the managed wetlands surrounding the lake, wading by flooded fields and marshes to feed their younger.
It is a year-round community. A residing, respiratory ecosystem that’s by no means really quiet—a spot of beginnings and endings and all the things in between for some 12 million birds, together with 339 species that use it yearly.
Audubon’s Nice Salt Lake Birds and Habitat Evaluation (Evaluation) supplies a spatial framework for understanding the place chicken habitat is most important at this time, the place it’s most definitely to matter below future local weather circumstances, and the way water strikes by the watershed to maintain all of it. This Evaluation goals to align conservation priorities and information coordinated motion for Nice Salt Lake’s panorama to guard birds and the habitats they rely upon.
The Evaluation attracts on habitat suitability fashions for 19 indicator chicken species throughout all seasons (breeding, nonbreeding, and migration) mixed with 2050 local weather projections and a hydrologic connectivity evaluation that maps the potential pathways by which water might attain the lake as return-flows from wetlands and flood-irrigated agricultural fields throughout the watershed. The result’s a layered, interactive instrument and actionable takeaways that may inform conservation practitioners, water and land managers, land use planners, and policymakers can use to determine the place conservation can have essentially the most sturdy impression for waterbirds.
Its most necessary discovering is solely: Defending Nice Salt Lake additionally means defending the system round it, which requires defending the water that flows from it.
Habitat prioritization should think about the intrinsic worth of particular person websites and their purposeful connectivity inside the broader panorama. Remoted habitat patches, irrespective of how high-quality, might not help viable populations in the event that they lack connectivity to different habitats or to important water sources. A system-level perspective that accounts for hydrologic connectivity, habitat connectivity, and helps the complete annual cycle wants of migratory birds at a hemispheric scale is important to information efficient conservation motion.
Birds don’t expertise habitat as people draw it on maps. They expertise a panorama, and so they want it to be functionally entire—related, wetted, and alive throughout its full extent. When any piece of that mosaic disappears, the loss ripples outward in methods which might be tough to foretell and infrequently unattainable to reverse.
As a longtime champion of Nice Salt Lake, Audubon will use the findings from this Evaluation to assist information its ongoing work on the lake together with managing Gillmor Sanctuary—the one sanctuary managed for shorebirds—and in its groundbreaking work co-leading the Great Salt Lake Watershed Enhancement Trust. The Evaluation additionally yields a number of key findings for different conservation companions working within the Nice Salt Lake watershed. Along with state and federal managers, personal landowners, agricultural operators, water rights holders and native governments are important companions for taking benefit of the chance to keep the mandatory redundancy and ecological integrity that sustains the area’s distinctive waterbird variety.

Nice Salt Lake is each a regional and a worldwide useful resource. As one of many largest saline lakes within the Western Hemisphere it generates organic productiveness that few ecosystems on earth can rival, helps 7,700 native jobs and practically $2.1 billion in annual financial output, and is a supply of identification and group heritage. Its waters bloom with brine shrimp and brine flies in extraordinary densities, offering a brilliant ample meals supply for birds which have traveled 1000’s of miles and must journey 1000’s extra.
Understanding Nice Salt Lake requires understanding all the things related to it. The lake itself is surrounded by roughly 350,000 acres of wetlands—managed ponds, seasonal mudflats, emergent marshes, rain-fed playas, and moist meadows that collectively type a various mosaic of chicken habitat.
For Utahns and guests alike, the lake and its surrounding wetlands are a supply of marvel, recreation, and identification. Birders journey from throughout the nation to witness the spectacle of shorebird migration. Hunters have pursued waterfowl within the lake’s marshes for generations. Households watch because the Eared Grebe dive under the floor from the causeway at Antelope Island State Park. That connection to Nice Salt Lake is a component of why this second is so pressing, and why we’d like a science-based framework to assist inform motion that’s centered on sustaining the hydrologic and land connections throughout the Nice Salt Lake ecosystem.
Nice Salt Lake is in bother, however it isn’t misplaced. What stays continues to be among the many most spectacular concentrations of birds wherever in North America.
The phalaropes are nonetheless spinning. The pelicans are nonetheless nesting on the islands. The pintails nonetheless pour south in autumn, banking over the marshes within the daybreak mild.
Their continued presence right here is dependent upon persevering with the deal with managing tradeoffs within the watershed and taking steps to keep water flows to the lake and the wetlands. Audubon constructed this Evaluation as a result of the birds deserve our greatest considering and since the individuals who love this place need to know that the case for safeguarding it’s a sturdy because the system itself, when it’s entire.
