After the 2020 wildfires, Kyle Trefny became a wildland firefighter, connecting with peers passionate about transforming society's relationship with fire. This led him to co-found FireGeneration Collaborative (FireGen) in 2022. FireGen is a youth-led organization dedicated to shifting wildfire management from short-term disaster response to long-term resilience and Indigenous leadership.

Trefny co-led FireGen's national campaign, advocating for youth roles in policy. This resulted in FireGen members advising a federal commission and Director Ryan Reed becoming the youngest federal advisor in US history. Trefny has also been instrumental in shaping FireGen's vision and securing over $350,000 in grants, empowering youth and Indigenous voices for the future.

Frustrated by the inaccessibility of climate action for young people, Vishruth Dinesh founded The Green Therapy in late 2022. At eight, he realized options like EVs or voting were out of reach for youth, making effective environmentalism seem a privilege. His grassroots organization aims to anchor young people in the climate movement.

The Green Therapy empowers youth through sustainable gardening, which reduces waste, preserves biodiversity, and combats pollution affordably. It partners with 14 San Francisco Bay Area schools, establishing environmental courses and garden programs. These initiatives equip students with practical skills to protect the planet, fostering a lasting connection to nature and building a growing school garden network.

This talk explores Sunset Crater, Arizona's youngest volcano, erupted 940 years ago, impacting the Sinagua people. Geologist Dr. Jeffrey Meyer will share its story and his work mapping the unique Bonito lava flow, notable for traveling uphill.

Understanding this flow aids hazard prediction and interpreting past flows on Earth, the Moon, and other planets. Dr. Meyer, a retired geology instructor, became curious about the Bonito flow, leading to detailed mapping via Lidar.

Pronghorn, often called "speed goats" or "antelope," are North America's fastest land animals, reaching over 55mph. This unique species, neither goat nor antelope, relies on speed and eyesight to survive on the plains. Despite their iconic status, pronghorn populations are declining in many areas, including the Verde Valley.

Join Forest Service biologists Janie Agyagos and Francisco Anaya for a Speaker Series talk. Discover pronghorn biology, from life history to threats like rangeland fences. Learn about current management tools, including tracking movement and ensuring fences are wildlife-friendly. Janie has 30 years of experience as a wildlife biologist with the US Forest Service, while Francisco manages wildlife for Prescott National Forest.
