California Conservation Garden and Native Plant Program

The Native Plant Program (NPP) at the UCSC Arboretum & Botanic Garden was featured in the NEWS! On November 17, 2022, the extensive California seed collecting & preservation work of Lucy Ferneyhough, NPP Program Manager and Alex Hubner, NPP Horticulturist and Garden Steward was showcased in the Mercury News.

Interactive Ecology interns will participate in fieldwork and building plant collections through seed germination, propagation, nursery work, and planting. All-day field trips to local wild areas will focus on plant communities and techniques involved in vegetation mapping, classification, habitat assessment, and surveys.

We will have discussions and pose questions about conservation and land management, ecology & evolution, and goals for the Arboretum native gardens. There will be assigned and optional readings. All participants will keep a journal. Photography, illustration, art and using GPS and smartphone technology will be encouraged (e.g. ESRI Collector).

The Interactive Ecology internship will also explore, more broadly, the gardens and collections in the Arboretum with room for individual participants to diverge into areas of special interest.


 Prerequisites: Outline the skills and background information necessary to participate in this internship.

  • Attention to detail
  • Basic knowledge about California floristics
  • Ability to use online and hard-copy resources (e.g., online search tools and websites, library books, journal articles, etc.) to research characteristics about plants
  • Ability to critically think and compile information from various sources
  • Enthusiasm about learning about different plants/vegetation, doing plant/vegetation research, data entry and quality control of data, and synthesis of information
  • Basic understanding of field data collection techniques and Geographic Information Systems (GIS)

If you have not previously applied, fill out and submit the Pre-Internship Survey.

"Pinus ponderosa: A checkered past obscured four species." By Ann Willyard, American Journal of Botany, 104(1):1-21, 2017. Recent genetic studies separate out local Santa Cruz Ponderosa Pines, like those in the Arboretum, as Pinus benthemaniana.

"Fostered by Fog", a recent article in UCSC's online journal Science Notes, uses the example of 'maritime chaparral' to explore the collaboration among the Arboretum's Native Plant Program, UCSC and the California Native Plant Society in preserving threatened native California plants. The article is written by Amy McDermott and beautifully illustrated by Yvonne Byers.

The late Bob Haller and his work on Pinus ponderosa var. pacifica (one of the Arboretum’s mascot species for the NPP): "John Robert (Bob) Haller, (was a) renowned California Botanist, inspirational teacher, and mentor to so many of us. Bob was international recognized for his work on pines but may be most remembered for the way he joyfully shared his love of the natural world with the rest of us - inspiring generations of botanists and avid naturalists." Read more.
