  • Christine Altermann — Curator of Collections and Propagator

    Christine Altermann — Curator of Collections and Propagator

    Email: calterma@ucsc.edu

    Christine Altermann grew up in California and spent her childhood gardening with her mom and visiting her grandparents in Chile. She has fond memories of spending time in her grandmother’s English-style garden and her extensive fruit garden in Valdivia, Chile. She traveled around with her family exploring the lush and picturesque areas surrounding Valdivia. She has lived in Santa Cruz for about thirty years and was first introduced to the Arboretum when visiting her sister, an Environmental Studies major at UC Santa Cruz and a student-worker at the gardens. After starting out in zoology, she discovered botany and decided to merge her love of design and plants by studying landscape architecture at UC Berkeley. She began working at Berkeley Horticultural Nursery which was an excellent training ground to learn a wide variety of plants, to be introduced to some of the most consequential plant people in the Bay Area, and to learn propagation. After moving on to work as propagator at Soquel Nursery Growers and Monterey Bay Nursery she began volunteering for her friend and mentor, Arboretum Nursery Manager Martin Grantham in 2018. She had always been interested in Mediterranean-climate plants, but working at Monterey Bay Nursery and the Arboretum, she vastly expanded her knowledge of plants from Australia, South Africa, California and New Zealand. When beloved, long time curator, Melinda Kralj, retired in June of 2021, Christine was promoted to Curator of Collections. She is honored with this privilege and looks forward to working with the fantastic team at the Arboretum as well as students, volunteers, visiting scholars, scientists, horticulturists, designers, foreign visitors, and plant enthusiasts.

  • Brett Hall  —  California Native Plant Program Director

    Brett Hall — California Native Plant Program Director

    Email:  brett@ucsc.edu  

    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.

    Jeremy Silberman - Native Plant Program Student Coordinator

    Jeremy graduated from UC Santa Cruz studying environmental studies and philosophy. Since 2020 he has been working and learning with the Native Plant Program at the Arboretum. It is here that he cultivated a passion for plants, land stewardship and design, conservation, and community engagement with the natural world. He is grateful to work so closely with such a beautiful and important place, and to have the privilege of facilitating others to experience that same joy. The main areas of the Arboretum that he and the students tend to are the California Conservation Garden, the World Conifer and Laurasian Gardens, as well as four nursery areas and a seed bank. Together, they grow and maintain our program with work that changes with the seasons like planting, mowing, irrigation, propagation, weeding, and pruning. Jeremy takes great pleasure in sharing his love for the Arboretum with others, teaching what he can, and always learning more throughout the process. When not roaming about the Arboretum he enjoys running, hiking, reading, cooking, and playing the guitar.
