Spring peepers are singing, and walleye harvesters are ready to go out on Mille Lacs Lake, as they have for hundreds of years. The walleye spawn is on.

Three members of the College of ACES community — Lisa Kelly, Carissa Nelson, and Mynda Tracy — are recipients of the 2026 Chancellor’s Staff Excellence Award. This is one of the highest honors for staff at the University of Illinois Urbana-Champaign and reflects the meaningful impact of their work across ACES and beyond.

Conservation tillage practices, such as no-till and reduced till, are critical for sustainable agriculture, and they are gradually becoming popular with farmers across the Midwest. Monitoring tillage usage can provide insights into soil health, water levels, and nutrient loss, as well as guide management and policy decisions. 

Last week, the U.S. Department of Agriculture announced a substantial reorganization of the Forest Service, moving its headquarters to Salt Lake City, Utah, and closing its existing regional offices. According to the announcement, the move is designed to move leadership “closer to the forests and communities it serves.” 

As winter comes to a close, many people look forward to warmer temperatures and spring blooms, but for land managers working to preserve or restore oak-dominated forests, it is prescribed burn season. Fire brings more light into forests, which is crucial for young oak tree growth, but many land managers are concerned about how non-native plants affect fire intensity and young tree survival rates.

Finding bats in the attic or under roof tiles is no homeowner’s idea of fun. But Florida’s endangered bonneted bats have few natural options left. With a dwindling number of large, old trees with cavities — their preferred habitat — and exotic species competing for what’s left, many bonneted bats have moved into homes, leading to panicked humans and calls to professionals who can oust the squatters.

In a world where increasing demands for food security and energy strain existing resources, scientists are looking for new ways to maximize both. One potential option, agrivoltaics, integrates solar photovoltaics with crops. A new study examines the agricultural and economic trade-offs that come with installing solar arrays on working farms across the Midwest.

A new accounting of nitrogen pollution in the Mississippi-Atchafalaya River Basin (MARB) reveals a significant decline in recent decades, suggesting positive momentum for water quality goals in local watersheds and the Gulf. Surprisingly, the University of Illinois Urbana-Champaign-led study doesn’t credit the change to reduced fertilizer application, but instead to cleaner air and more efficient nitrogen uptake by modern corn hybrids. 

Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there’s a dark side to the amphibian trade, according to a recent study from the University of Illinois Urbana-Champaign. 

Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction — according to new research from the University of Illinois Urbana-Champaign. The advancement marks the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria, the microbes responsible for turning fertilizer nitrogen into forms that pollute water and contribute to climate change.
