  • Brett Hall  —  California Native Plant Program Director

    Brett Hall — California Native Plant Program Director


    I was born and raised along the Central California coast, mostly in the Monterey Bay region. In the early 70s, I worked at my family's landscaping and garden design business. I was an undergrad at UCSC and worked at the Arboretum, graduating with a BA in Natural History and Biology. I started on the staff in October 1975 and became garden manager in 1976. My duties have evolved over the past 30 years into my current position. I oversee the horticultural staff and my role with that is increasingly as an advisor/coach, as well as working to get them the resources they need to succeed. I am continuing to play an active role in the development of many of our collections and have traveled overseas and throughout the West to accomplish this. I have been very fortunate to spend 30 years working in the Graden developing collections, planting gardens, and working with our wonderful group of staff, students and volunteers. My special interests include many of our collections but I plan on focusing considerable effort in the development of our native plant program and the California Province Gardens. I enjoy working with dedicated volunteers who have a genuine interest in botany and horticulture. [Brett is now President of the California Native Plant Society.]

    Katie Cordes — Volunteer Program Coordinator

    Phone (831) 502-2300

    Katie began work at the Arboretum in 2008, as an Administrative Assistant. In 2011, she transferred to campus administration working in the Chancellor’s Office and in 2014, was thrilled to return to the Arboretum with a deeper appreciation for the beauty and importance of the Arboretum’s unique collections and role in education and plant conservation. 

    With the support of an AmeriCorps V.I.P. Volunteer Coordinator, Katie oversees volunteer recruitment, orientation and training, event coordination, communications, and the overall building and strengthening of the volunteer program. She enjoys working with dedicated volunteers throughout the gardens, in the Lane Horticultural Library, for special events, and at Norrie’s Gift Shop. She is Staff Liaison to the Arboretum’s Education and Outreach Committee. In addition, Katie assists with day-to-day office tasks and event planning and logistics.  

    Katie’s love of plants began as a child in the vegetable garden and continued to grow as she did, leading her to obtain a B.A. in Biology from UC Santa Cruz in 1997. She loves the diverse Californian landscapes and is especially drawn to trees and forest life. She is a certified California Naturalist and participated with her daughters in the Riekes Nature Awareness Program. When not at the Arboretum, Katie enjoys spending time with her family and friends, cooking, hiking, gardening, reading, learning, listening to music and being outdoors.

    Melinda Kralj — Curator of Collections

    Phone: (831) 502-2309
    Email: mkralj @ 

    I graduated from UCSC in 1978 with degrees in Biology & Art. I worked at San Lorenzo Garden Center for over a decade. While working at the nursery, I began volunteering at the Arboretum, and was hired in 1989. I take care of the Australian Collections. Most of my time is devoted to the Slosson Gardens and the Banksia Field. Our most-recent addition is the exciting and challenging Australian Rock Garden. In the future, I would like to devote more time and energy to give the Eucalyptus Grove the attention it deserves. Every Thursday morning, a dedicated, hard-working group of volunteers called the "Aussie Weeders" contribute their hard work and creativity to making the Australian garden more beautiful.

  • Samantha Spurlin

    Samantha Spurlin-- Plant Inventory Specialist


    I grew up on the Central Coast of California with an affinity for the outdoors. I transferred from Cuesta College to UCSC in 2012 and graduated in 2015 with a degree in Environmental Studies and Biology. I began at the Arboretum in winter 2013 as an undergraduate working primarily with Brett Hall and Rick Flores in the California gardens. I was hired part-time as Plant Inventory Specialist in March 2016 and elevated to full-time staff in January 2018. In this position I assist with inventorying and maintaining data on our diverse collections working directly with the Curators, produce signage and interpretation, and assist the California Native Plant Director, Brett Hall. I’m excited to have started a Plant Inventory Internship and Volunteer opportunity in spring 2018 and look forward to sharing the wonders of the Arboretum with the world.
