7 FOCUS - FALL 2025 JENNIFER KILLIAN Originally from south-central Wisconsin, Killian first developed an interest in municipal forestry through work at the Wisconsin Department of Agriculture. She earned a master’s degree from Oregon State and, after gaining experience across nonprofit, municipal and state sectors, is excited to return to the university. “We’re currently reflecting on the unique urban forestry needs of Oregon’s communities and asking how we can help address and meet those needs through our Extension work,” Low said. Their efforts include developing educational materials, leading workshops on small-tree structural pruning and helping communities preserve trees during development. They’re also contributing to statewide efforts to prepare for emerald ash borer — an invasive beetle that threatens ash species. For both specialists, urban forestry is as much about people as it is about trees. Most people live in cities and may not have direct access to large forests or wilderness areas. The trees they interact with daily on streets and in parks shape their relationship with nature. “Working to improve the health of trees in communities while building community around trees allows me to contribute positively to something bigger than myself,” Low said. The work can be hard and, at times, thankless, Killian noted. One of the most misunderstood aspects of urban forestry is the balance between preserving trees and making informed decisions that promote long-term canopy health, safety and equity. “People are, rightfully, passionate about the trees in their community, and navigating those emotions with care while advocating for trees as a shared resource is not always easy,” Killian said. “But making sure people have a safe, reliable connection to trees and nature where they live is what keeps me going.” Urban forestry is at a pivotal moment — facing significant challenges from increased development pressure, emerging pests such as emerald ash borer, climate change and the need for equitable access to green spaces. “But at the same time, I’ve never seen so much energy and passion for this work, which gives me a lot of hope,” Killian said. “We have an opportunity right now to shape more equitable, resilient urban forests, and I feel incredibly grateful to be a part of that work, especially here at Oregon State.”
