Wildlands Urban Interface (WUI) Research for Resilience: Addressing California’s Climate, Conservation & Housing Crises
The Wildland Urban Interface (WUI) —where human development mixes in with or abuts undeveloped natural areas— is the fastest growing area of housing growth in California, as well as a leading cause of wildfire, habitat fragmentation, and climate change. Yet there is no systematic research on what is driving this growth. In this project we seek to understand these drivers, through a case study on the Central Coast. First, we recognize that they are complex, multiple, and often entangled with each other, much like the lands of the WUI themselves. Areas designated “WUI” include lands stewarded by California tribes, harvested by farmers and ranchers, developed over generations by rural communities and, increasingly, sought out by new residents, from commuters to retirees. In addition, with many WUI areas more affordable that neighboring cities, we hypothesize that the California housing crisis –which is the worst in the nation—is playing an increasing role in displacing people from cities to WUIs, as well as in making these areas more hazardous and unequal. Thus complex combinations of desirability and affordability may help explain WUI growth, while a mix of interventions— from land stewardship to hazard mitigation to affordable housing—may be needed to address the issue. To investigate, we conduct the first comprehensive study of the drivers, demographics, and dynamics of WUI growth—drawing on ethnographic, historical, ecological, spatial, and statistical methods. With their location at the socio-environmental interface, we hope WUI can serve also as an interface for new ways of thinking about climate, conservation and housing needs for the region and beyond.
Events
Our team is led by faculty and students in the social and natural sciences working alongside community partners in affordable housing, labor, Indigenous land stewardship, prescribed burning, conservation, and emergency response. Over the coming two years, we will host regional gatherings to share and get feedback on our findings from a range of stakeholders, and present our multiple layers of research within an online, interactive WUI Equity Atlas. Our ultimate goal is to inform and inspire new approaches to regional resiliency planning at the nexus of climate, land, and housing justice.
Affiliated Research
WUI Ethnography
Through surveys and interviews with WUI residents, observation of community dialogues, and archival research, we will explore the affordability-desirability nexus motivating people to move to the WUI, uncover emerging obstacles to prescribed burning in WUI areas, and build deeper understanding of the history of fire in the Santa Cruz Mountains.
Research projects in this area of study include:
- Housing + Habitat Resource Fairs and Surveys
- Living with fire: ethnography
- Archival history of the Santa Cruz Mountains
WUI Fire Ecology
We will carry out pre- and post-fire ecological surveys for prescribed burns, with the specific aim of determining where and when this practice can be most effective for native plant ecology and habitat restoration in the WUI. We will also conduct a fire return interval departure analysis to show the difference in fire frequency in WUI areas before and after development.
Research projects in this area of study include:
- Prescribed burn plant surveys
- Fire return interval departure analysis
WUI Spatial Analysis
We’re conducting statistical and GIS analysis of the 3D’s of WUI growth: the drivers that encourage migration to the WUI, demographics of who’s living in the WUI, and resulting dynamics, like growing commute sheds and vulnerability to climate-related hazards. We’ll also identify distinct socio-environmental typologies for the WUI.
Research projects in this area of study include:
- 3 D’s analysis
- Socio-environmental typologies analysis

University of California affiliated programs
- The Amah Mutsun Relearning Program (AMRP) at the UC Santa Cruz Arboretum & Botanic Garden is a collaborative effort between the Amah Mutsun Tribal Band (AMTB) and the Garden to assist the Tribe in their efforts of cultural revitalization, recuperation and relearning of dormant cultural knowledge, and environmental justice. This unique process of relearning combines science, research of Smithsonian ethnographer John P. Harrington’s interviews with Mutsun elder and tribal matriarch Ascension Solorzano, and other Mutsun members, in the late 1920s, oral histories of Amah Mutsun tribal members, and knowledge and information from surrounding California Indian tribes with similar cultures.
- The Native Plant Program at the UC Santa Cruz Arboretum & Botanic Garden is dedicated to the conservation of California’s flora, through the development and stewardship of the gardens and surrounding lands, student engagement via the interactive ecology internship and applied botanical conservation projects including seed banking, vegetation sampling and native plant horticulture.
- The UCSC Campus Natural Reserve (CNR) focuses on engaging students in direct observation and study of the natural world and bridging concepts learned in the class with hands-on experiences. Each year, thousands of students visit the CNR and surrounding natural lands as part of their coursework, and over 100 deepen their educational experiences through experiential internships. CNR staff also engage in large-scale planning and land management efforts, including the use of prescribed fire. The CNR is planning two small coastal prairie burns that Cal Fire will conduct in fall 2024 and that will be included in WRR research.
- The Center for Integrated Spatial Research (CISR), formerly the GIS/ISC Laboratory, is the central facility for spatially-focused research and training at the University of California, Santa Cruz. CISR is focused on integrating state-of-of-the-art spatial technology and methods (geographic information systems, global positioning systems, remote sensing, spatial modeling/statistics) with pressing interdisciplinary research and fostering cross-domain cooperation in the application of these tools. In order to advance this purpose, CISR is dedicated to promoting a diversity of research by increasing campus and community literacy in spatial methods and engaging in innovations in spatial science.
