• Welcome to the UC Master Gardener Program's Recorded Trainings

    To become a  UC Master Gardener, volunteers must complete an intensive home horticulture training and pass an exam testing their knowledge and ability to find scientific-based answers to public inquiries.  Training programs throughout the state vary greatly in class size, lecture vs. hands-on time, length of sessions, etc.  Due  to COVID-19 and the safety of our communities a statewide order of sheltering-in-place for California has made it necessary to cancel and or postpone all in person training classes.

      • 1. Home Survival in Wildfire-Prone Areas Design and Maintenance Considerations

        Single FlameSpeaker:  Yana Valachovic, County Director and UC Forest Advisor, Humboldt & Del Norte Counties
        Format:  YouTube Video
        Duration:  1 hour (self-paced)
        Continuing Education: UC Master Gardeners record 1.0 hour of continuing education in the Volunteer Management System.  

        Description  

        “Life in Southern California is being transformed as the climate grows hotter, drier and in places like Ventura County, windier. In the last few years, this dangerous combination has fueled some of the largest and most destructive wildfires in the state's history. Consequently, Master Gardeners are fielding more questions around the topic of fire-smart home design and landscaping.

        Valachovic discusses  changes in defensible space policy and home construction guidelines. The presentation will cover the three key points that assist in home survival: 

        1. Careful landscape selection, placement, and maintenance
        2.  Awareness and management of combustible materials on the property (e.g. leaf litter or lawn furniture) during your fire season, and 
        3. Incorporation of fire and ember resistant construction materials, installation details and maintenance.

        Developing wildfire resilience is more than having a metal roof or stucco siding. Ember-resistant construction relies on awareness of seemingly small details that can make your home vulnerable to embers, in addition to building with appropriate materials, and regular home and property maintenance. 

        The UC Master Gardeners are an important arm in the UC's fire resiliency educational messaging.

In this environment of broken routines and uncertainty, chances are you - and those around you - are experiencing big feelings. Stress and coping are frequent topics of discussion as worklife, homelife, and social life collide, expand, and contract. Everyone reacts differently to stressful situations and we are all in need of tools, new and old, to improve our resilience. After all, taking care of yourself, your family, and your friends can help you cope with stress and can make your community stronger. 

        The speakers focus our attention on taking care of ourselves and each other. You’ll learn about the therapeutic benefits of gardening, mindfulness-based stress reduction, and personal resilience. Whether you are a University of California employee or a volunteer, creating an oasis during challenging times could be the most important task of all.
