    Unnatural Disasters

    Content Warning: This article discusses Hurricane Helene, Hurricane Milton, Hurricane Harvey, and other climate change-related issues and impacts that might be hard to read for some. We are sharing it here because we think it will be helpful to our community in communicating about the influence of climate change on current events, and for preparing our community for the ongoing and increasingly compound and cascading impacts of climate change. I am so grateful for the incredible community of...

    Why Become a Certified California Naturalist?

      I recently came across a national forum thread on iNaturalist where someone was curious to know more about the value of becoming a “certified” naturalist. Not surprisingly, there was a wide range of opinions. These ranged from supportive to skeptical to cynical. Because many of the responses came from people who have not taken a course themselves, I thought it might be valuable to share some data from people who actually completed a course – in this case,...

    Joshua Trees at the Hub of an Ecosystem

    A blog re-post from our Lead Scientist Dr. Cameron Barrows on the importance of preserving those organisms that are at the core of each ecosystem, using Joshua Trees (Yucca brevifolia) as an example. “We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity.” – E.O. Wilson “Important” is a word we use to indicate something has value. The problem with “important”...


  • New Volunteer Portal Rollout!

    Dear California Naturalists and Climate Stewards: We are pleased to introduce you to the new Volunteer Portal! Over the last year, we've developed a new platform for our naturalists, stewards, and instructors to record, review, and generate reports on their volunteer service. This replaces the UCANR VMS (volunteer management system) and provides new capabilities and will streamline some common processes.  This week, we are transitioning to this new Volunteer Portal and this post provides...

    Thank You & Farewell, Brook!

    After 9 years of expanding and improving the California Naturalist program and helping to usher in the UC Climate Stewards course, our Coastal Northern California Community Education Specialist, Brook Gamble, is moving on to a new organization.  Brook has been at the forefront of CalNat's evolution and has molded many of the systems we use to make our program the success it is today. As one of our lead communicators, her success was in large part because she had her finger on the...

    Biodiversity Writ Large

    A "Natural History Note" From UC California Naturalist's lead scientist, Dr. Cameron Barrows. “It is that range of biodiversity that we must care for - the whole thing - rather than just one or two stars.” – Sir David Attenborough That range of biodiversity includes the panoply of life occupying a region. Everything from charismatic species (those one or two stars), bighorn sheep, collared lizards, wolves, and mountain lions, to microscopic soil organisms. Everything...

    Gratitude

      At CalNat, we are grateful for the partnerships we've formed with over 55 organizations across the state with whom we share a vision of a more sustainable and just future. This year we are particularly grateful for our new partners that represent several Indigenous cultures across California. We are honored by their choice to work with us and the wisdom they bring to our program. While our focus is forward looking and hopeful, we'd be remiss not to reflect on our complicated and...

    A Model for Engagement and Empowerment for Biodiversity Conservation

      The California Biodiversity Collaborative correctly identifies “engage and empower” as one of four key strategies for biodiversity conservation. Together with “knowledge,” “protection, “and “restoration,” the state seeks to put people at the center of its strategy to protect the genes, species and ecosystems that sustain our society and economy. The emphasis on engagement and empowerment is well founded as it is one of the most...

    Providing Context

    A "Natural History Note" From UC California Naturalist's lead scientist, Dr. Cameron Barrows, in celebration of California Biodiversity Day.     “Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage to move in the opposite direction.” - E.F. Schumacher Asking questions about patterns in nature, or perhaps the sometimes apparent lack of patterns, can seem to lead to more...

    Detecting Climate Change Impacts

Nobody's going to buy their way out of its effects.” - Mark Ruffalo The environment is changing. There is a daily cycle governed by the earth's rotation – warmer days and cooler nights. There is a seasonal cycle governed by the tilt of the earth toward the sun...
