Emeritus Master Gardener Rod Haulenbeek: Farewell to the Tree Hunter and Keeper of the Magic Box

From the desk of Rachel McClure, Washoe County Master Gardener Coordinator

“We make a living by what we get, but we make a life by what we give.” – Winston Churchill

What a rich life Rod must have had. He gave so much to everyone he met. If you shared his passion for life, trees, native plants, any plant really, it was impossible to have a conversation with him without a smile, handshake or a hug. His energy and enthusiasm were contagious, and he had a humorous story to support every point he needed to make. Rod made each day a great day.

Rod loved trees. Rod loved shrubs. Rod loved seeds. Rod loved plants. They called to him and he returned the call. He was lucky enough to realize his passions early in life in his childhood back yard and he took that same joy and curiosity with him into every single day. He found the interesting and new. He learned the whys’ and how’s for all the plants he encountered. In this process he discovered there was a need for information, so he filled that need by writing and publishing several books:

  • Tree Adventures at Tahoe by Rod Haulenbeek ISBN: 978188515503
  • Northern Nevada Tree Identifier: A Photographic Album of Native and Introduced Trees of Northern Nevada in Winter, Spring, Summer, and Fall. ISBN: 978-1984953834
  • Northern Nevada Shrubs and Vine Identifier: A photographic Album of Landscape Shrubs and Vines of Northern Nevada ISBN: 979-8645727345
  • Tree Adventures in Yosemite Valley ISBN: 978-1885155023
  • A Visitor’s Guide to the University of Nevada, Reno Arboretum: ISBM: 978-1943859320

Rod, also known as the Tree Hunter, played an integral role in finding Nevada’s big trees. He discovered Nevada’s champion Eastern White Pine, which is also the biggest in the nation. The Nevada Division of Forestry’s Big Tree program has some great information. Also, on YouTube all 28 of his tree walks of the UNR Arboretum and campus are archived. He also did many tree walks throughout our communities for industry professionals, Extension Master Gardener Volunteers and community members. Rod was Someone 2 Know as featured on the KTVN segment. Additionally, he worked with the University of Nevada, Reno Extension in creating tree care videos.

Rod took the Master Gardener program in 1999, certifying in 2000. While he lived in Reno, he drove all the way to Carson City to participate in the program. As a Master Gardener, he participated in numerous events, always sharing his passion and his enthusiasm for gardening and specifically, his desire to identify whatever plant he saw, from childhood interest to moving to a new area and not knowing any of the plants or fauna where he moved to. He was part of the Master Gardener Greenhouse, Historic Huffaker School Garden, Home Show, The Master Gardener Seedling Sale, Seed Swap (The Magic Box), Gardening in Nevada: The Bartley Ranch Series (where he volunteered for years before he began presenting and he did 10 or more presentations). He hosted several “Tree Walks” for Master Gardeners and as a presenter for Gardening in Nevada: The Bartley Ranch Series he covered a multitude of topics from Seeds, Trees and Landscaping.

You could always find Rod in the community. Find a plant community, and he would be part of it in some way. He was an active member of the Wilbur May Arboretum and deeply involved with the City of Reno Greenhouse for many years. He was also heavily involved with the University of Nevada, Reno Arboretum and their board. Whether he was leading an educational program, actively volunteering, or simply participating, Rod showed up for anything related to plants.

He also had a gift for building community. Rod was passionate about connecting people with shared plant interests and needs. He collected seeds, hunted acorns with friends, grew plants, and shared them at every opportunity. Many people in our community have a tree grown from one of Rod’s acorns or a plant he nurtured from seed in his own yard. Countless community members and Master Gardeners have plants grown by Rod that they discovered at the Master Gardener seedling sale.

And then there was Rod’s beloved “Magic Box” — always full of carefully collected, sorted, seasoned, and packaged seeds, ready to share. Each packet was thoughtfully labeled with growing instructions, pictures, and anything else he believed someone would need to succeed. Multitudes of Master Gardeners and community members carry seeds from that "Magic Box", and with them, a small piece of Rod’s generosity and spirit.

Rod Haulenbeek enriched our community on so many levels. His passion for plants and his desire to connect everyone around them has had a profound impact. He will be missed every single day.

Thank you for your part in our journey, Rod the Tree Hunter and keeper of the Magic Box. Rest now. Your legacy lives on forever.

*Several organizations are planning memorial activities, and tree plantings in Rod’s honor. The University of Nevada, Reno Arboretum, Washoe County Master Gardeners, Wilbur May Arboretum and others. Please check with these organizations for details.

Master Gardeners Contribute to Roots to Results Conference in Southern Nevada

Extension Master Gardeners played an active and impactful role at this weeks Roots to Results Conference, an event produced by UNR Extension's “Community Driven Tribal and Agriculture Programs” team. The conference brought together more than 125 participants from across Southern Nevada to learn about strengthening regional food and agriculture systems.

The conference offered four focused educational tracks:

  1. Agriculture, Nutrition, and Food Systems – exploring community nutrition, food access, and local food programs.
  2. Agricultural Production: Crops, Livestock, and Ag Innovation – covering desert farming practices, livestock management, and emerging technologies.
  3. Conservation and Sustainability – highlighting soil health, water conservation, pollinator support, and climate-adapted practices.
  4. Profitability, Business Planning, and Financial Management – supporting producers with tools to strengthen economic resilience.

Master Gardeners contributed primarily within the Conservation and Sustainability track, offering presentations on Composting Basics, Building Solitary Bee Houses, and Creating Pollinator Habitats. These sessions provided participants with practical, research-based techniques they can apply at home or in community spaces to support soil stewardship and local pollinators. In addition, Master Gardeners sponsored a breakout session in the Extension Botanic Gardens, where attendees explored the living collections, learned about ongoing plant research, and experienced how the gardens support desert horticulture education. 

Throughout the event, Master Gardeners also staffed a horticulture literature and information table, answering gardening questions and connecting attendees with reliable, science-based resources. Their involvement reinforces the Master Gardener Program’s continued commitment to education and community engagement throughout Southern Nevada.

Roots 2 Results will be hosting a Northern Nevada Conference March 24-27 in Sparks, NV.

Department of Energy awards $9 million for national research project on cactus pear’s bioenergy potential

University of Nevada, Reno researchers will lead the multistate five-year project

field of cacti

As the quest to diversify and expand sustainable alternative energy products continues, the U.S. Department of Energy has awarded a $9 million grant to support research that will be led by researchers at the University of Nevada, Reno to expand the use of cactus pear as a low-water-use, climate-resilient biomass crop and potential biofuel feedstock.

During the five-year, multi-institution project, a national team will conduct cactus pear field trials at sites across the U.S. to identify varieties that produce the highest biomass with minimal water and other inputs.
