12 COLLEGE OF FORESTRY 12 COLLEGE OF FORESTRY Oregon State University has a new face leading its Extension Christmas tree program — and she’s bringing science, passion and a deep appreciation for growers with her. Priya Rajarapu, an experienced entomologist and molecular biologist, recently took over as OSU’s second-ever Christmas tree specialist, following the retirement of longtime expert Chal Landgren. Rajarapu’s journey began in labs, but it was her hands-on experiences with North Carolina growers that sparked her passion for Extension work. Now based in Oregon — the nation’s top Christmas tree-producing state — she’s focused on helping growers tackle real-world challenges like extreme weather, pests and seedling survival. “My work is about more than lab science,” Rajarapu said. “It’s about serving people and solving problems.” Her research includes improving pest management using growing degree day models and exploring the best soil treatments to help young trees thrive. She’s also looking at the economic side of growing popular fir species such as Nordmann and Turkish firs and plans to hire a graduate student to help scout for pests across the region. Rajarapu has already built strong connections with Oregon growers, whom she calls the real experts. Her goal? To keep trees healthier and more plentiful — and ultimately, more affordable. “I like to say I want a real Christmas tree in every house,” she said. With science in her toolkit and community at the heart of her mission, Rajarapu is helping shape the future of Oregon’s $117 million Christmas tree industry. KEEPING THE ENGINE RUNNING: RESEARCH, RESILIENCE AND REACHING COMMUNITIES DURING UNCERTAIN TIMES 2025 has been a challenging year across the natural resources and research landscape, with multiple rounds of federal funding cuts at the National Science Foundation and staff reductions at the U.S. Geological Survey, National Park Service and other key agencies. Still, the OSU College of Forestry continues to advance vital work and partnerships that shape the future of forests, ecosystems and communities in Oregon and beyond.
