One of those fires, the Sand Stone Fire, damaged areas in Central Arizona just northeast of Phoenix. While, thankfully, the fire did not damage any homes or claim any lives, it did burn portions of the Sycamore Creek site of the NSF National Ecological Observatory Network (NSF NEON). As the damage is remedied, researchers could use the impact and data NSF NEON collects to learn more about how fire interacts with the environment. </span><span> </span></p><p><span lang="EN-US"><strong>Ecology of fire in the Sonoran Desert</strong></span><span> </span><br><span lang="EN-US"></span><a href="https://www.neonscience.org/field-sites/syca"><span lang="EN-US"></span></a><a target="_blank"></a><a href="https://www.neonscience.org/field-sites/syca" target="_blank"><span lang="EN-US"><u>Sycamore Creek</u></span></a><span lang="EN-US"> is an aquatic NEON site in the Tonto National Forest, managed by the U.S. Forest Service (USFS). The area, broadly part of the Sonoran Desert, is populated by a mix of native and invasive plant species, with many of the latter brought in by humans.

"In the areas you see along highways or in intense recreation areas like at the NSF NEON Sycamore site, the shrubs eventually just kind of give up. And it becomes a grassland."</span><p><span lang="EN-US">As fires become more frequent, they are also becoming larger, according to Lata. </span><span> </span></p><p><span lang="EN-US">"Fires are getting bigger because of the contiguous fuel load from grasses, and it's mostly introduced grasses, red brome. But they've been here for so long, we can't get rid of them, and so that IS the system now," she said.</span><span> </span></p><p><span lang="EN-US"><strong>Studying disturbance in Sycamore Creek</strong></span><span> </span><br><span lang="EN-US">The area in and around Sycamore Creek has been used to study the impact of environmental disturbances for some time. The work has been funded by NSF investments as well as those of other federal agencies.</span><span> </span></p><p><span lang="EN-US">In addition to fire, the area faces disturbance from flooding that results from heavy rains during monsoon season, leading to impacts on both the biology and geology of the area. During the dry season, the potential for wildfire is high, and the ecosystem can take decades to recover from large fires. Additionally, the changing landscape and introduction of invasive plant species provide a unique vehicle to study the impacts of ecological change. </span><span> </span></p><p><span lang="EN-US"></span></p><p><span lang="EN-US">Since 1997, the Central Arizona-Phoenix site of the NSF Long Term Ecological Research site, managed by Arizona State University, has engaged in research on the human-environment interactions mediated by urban ecological infrastructure in the Phoenix metro area and the surrounding parts of the Sonoran Desert. USFS conducts research and management activities that support native flora and fauna (especially rare or endangered species), invasive species removal and monitoring, riparian resources protection, mining and grazing permitting, and wilderness areas management.</span></p><p><span lang="EN-US">NEON, through instrumentation, field collections and airborne observations, collects an array of data at Sycamore Creek. This includes information on vegetation composition and the amount of area covered with plants, ecosystem structure, relative humidity, wind, temperature, precipitation, streamflow, aquatic organisms and more. The observatory collects these data at each of its other 81 sites across the country and provides them all openly and free. These standardized data from across ecosystems enable novel research on the impacts of ecological disturbance.</span><span> </span></p><p><span lang="EN-US">"NEON is discovering processes operating at continental scales that determine ecosystem responses to droughts, floods, hurricanes, wildfire and other large-scale disturbance events," said Andrew Elmore, program director in the NSF Directorate for Biological Sciences, who works on the NEON program. "These disturbances can cause direct or downstream effects on natural resources on which society is dependent and that are costly to remedy, so it is critical that we monitor these things."</span><span> </span></p><table><tbody><tr><td><p><strong>Facts about the Sand Stone Fire</strong></p><ul><li>Start date: July 25, 2024.</li><li>Cause: Started by lightning strike.</li><li>Originating Location: 14 miles northeast of Fountain Hills, Arizona.</li><li>Largest Size: 27,390 acres.</li></ul></td></tr></tbody></table><p><span lang="EN-US"><strong>Impact on NEON and possibilities for research moving forward</strong></span><span> </span><br><span lang="EN-US">The Sand Stone Fire damaged communication and power equipment at Sycamore Creek, but the automatic sensors that collect the data were unaffected.
