Join us on Zoom: 7 PM Thursday, May 15, 2025 Register to hear Kyle Merriam (USFS, Sierra Cascade Ecology Program) discuss the rare Baker cypress (Hesperocyparis bakeri) and Macnab cypress (Hesperocyparis macnabiana) found in scattered, isolated populations in northern California. These cypress species depend on high severity fire to reproduce, and require at least 30 years to accumulate enough cones to replace the parent generation after a fire. A recent increase in the frequency of high-severity fire poses a serious threat to both cypress species. Over half of the cypress populations have burned in the past 15 years and are now only at seedling stage. Four Macnab cypress and one Baker cypress population have been extirpated due to repeated fires that killed immature seedlings before they produced cones. Neither species of cypress has protected status at the federal or state level and over half of Macnab cypress groves occur on private land. In this talk we will review the status and distribution of these two rare conifers and discuss efforts to protect and conserve these two iconic, fire adapted species.
