Conservation BIPOC PerspectivesThe CNPS BIPOC Group came up with the BIPOC Perspectives session in which BIPOC presenters could have a space to speak upon their experiences in the conservation community. The aim is to highlight BIPOC work and perspectives historically ignored in the conservation community.
Session details
ConservationLand Back and Comanagement with Traditional Ecological KnowledgeColonization dispossessed indigenous peoples of their ancestral lands thus removing indigenous cultural and stewardship activities from occurring on the landscape. The conservation movement in California is well positioned to support indigenous peoples gaining free, unfettered and undisturbed access to their lands. This session will cover #LandBack efforts, where indigenous peoples are advocating for and gaining ownership and access to their ancestral lands to manage and co-manage ecosystems using traditional ecological knowledge. Learn about ways you can support and uplift the #LandBack movement.
Session details
ConservationSeeing the Forest for the Trees: Conservation in the Face of Timber Harvest and Fuel ManagementWhat would California’s forests look like absent 200 years of aggressive timber harvest and 100 years of fire suppression? How do we restore and maintain a more natural forest structure and appropriate fire regime? What are the risks if we don’t act? This session will look at the historic condition and influence of indigenous management in the fire-adapted forests of northern California, as well as current forest condition and trends, and discuss actions (including timber harvest) and key issues to consider in restoring our frequent-fire forests.
Session details
ConservationGood Fire: How Restoring Ecosystem Processes is Key to Ecosystem HealthAlthough often maligned in the media, much of California’s flora is adapted to fire and the restoration of this process is vital for conservation and ecosystem management. Prescribed fire and the cultural burning practices of Native Americans have great potential to ensure that habitats continue to be biodiverse, while increasing the safety of human communities.
Session details
ConservationResilience in the Face of FireFire is a fact of life in California. While this natural process is essential for most of our state’s ecosystems, challenges ensue when human infrastructure intersects with wildfire. This session explores the myriad ways that people are working to adapt to life with fire while ensuring that habitats and ecological processes remain intact.
Session details
Conservation Climate Change, Conservation Science, and Adaptive ManagementClimate change poses novel risks to species, from contributing to changing fire regimes, drought, the spread of invasive species, and influencing shifts in the ranges for native species. This session will focus on climate change through the lens of conservation science, how this impacts management decisions, and how adaptive management is more important now than ever.
Session 8 details / Session 23 details
Plant ScienceVegetation Mapping & Monitoring (new & traditional technologies)Government agencies, NGOs, academic institutions, and consulting firms continue to improve standards, techniques, and resulting products of vegetation mapping — especially since Geographic Information Systems, imagery, LiDAR, and remote sensing technologies have expanded from the late 20th Century on through today. Vegetation mapping and monitoring are important tools for species, habitat, and landscape-level assessment, analysis, monitoring, and conservation, driving many of today’s decisions for land-use planning. This session showcases promising uses of vegetation mapping and monitoring to positively impact decision-making in conservation and management throughout California.
Session 12 details / Session 17 details
Plant ScienceConifers in the Face of Climate ChangeConiferous vegetation occurs from the Coastal zone (coast redwood, coastal cypress) to high-elevations (whitebark pine, bristlecone pine) and areas in between in the foothills and mountains (coastal Douglas-fir, Pacific ponderosa pine). The risks they face due to climate change, insects, and pathogens, intensive logging, large scale and severe wildfires, and other stressors are immense. This session focuses on research and management efforts underway today in California to examine the status and trends of coniferous vegetation in response to climate change and other interacting stressors.
Session details
Plant ScienceChaparral Resilience and Future Concerns Chaparral contains 24 percent of California’s native plant species, and more of these plants are considered rare here than in any other plant community. Since chaparral exists in every single county, chaparral represents the most accessible native plant experience to the greatest number of Californians and visitors to our state, and it provides unique research and educational opportunities. Due to the uniqueness of chaparral it presents major challenges to fire managers concerned with balancing fire hazard reduction and resource conservation. This session will explore the remarkable biodiversity, resilience, and value that chaparral provides to all the life forms and the need to address threats to vegetation type conversion in light of many global changes.
Session 6 details / Session 16 details
Plant ScienceOaks & Oak Woodlands Oak woodlands have been enduring anthropogenic threats since the state of California was formed in 1849. These threats include urban and agricultural development and ranching, fire suppression, and a mosaic of pressures – disease, drought, invasive species, and fire – associated with and exacerbated by fire suppression, unintended horticultural practices, and a changing climate. This session will examine critical California oak woodland habitats by exploring the science, policies, cultural burning, and other practices necessary to conserve, stabilize, and regenerate critical oak woodlands ecosystems in the face of ever-increasing social, climatic, and ecological pressures.
Session details
Plant ScienceGrasslands & Prairies California grasslands are among the most endangered ecosystems in the United States and are important subjects of ecological research and experimentation. This session focuses on native grassland research and management including biodiversity enhancement, invasive species, livestock grazing, and restoration within our unique California grassland/prairie ecosystems.
Session details
Plant ScienceFloristics The field of floristics covers the range of studies focused on documenting and understanding the components of the flora of a local area, a county, regions, to the entire state, and beyond. Floristics covers the basic components that supports a wide range of disciplines, from basic science to land use planning. Without understanding the flora, we are just guessing as to what the flora of a given area is, including the common and rare species.
Session 37 details / Session 42 details
Plant ScienceRare Plants Rare plants make up one-third of California’s native flora. They encompass nearly every habitat type and elevation range, are beautiful, and are important contributors to pollinators, ecosystem functions, and the rich biodiversity of the state. While great progress has been made at broader levels—families and genera— the California flora is still far from being understood at the species-level and it’s expected that hundreds of taxa have gone unnoticed by taxonomists; most of these will have narrow ranges and thus be more vulnerable to human impacts. Powerful tools are now available to describe and understand plant diversity in California, including a host of reduced representation sequencing methods, to understand fine-scale diversity and evolution.
Session 26 details / Session 36 details / Session 41 details
Plant ScienceEffects of Fire Suppression & Fuels Management on Rare Plants California’s native flora, including rare plants, is widely assumed to be fire-adapted because fire has been a regular ecosystem disturbance process for millennia. Now that we are seeing dramatic effects of the Pyrocene period created by humans, there is a new urgency to understanding the roles played not just by fire in California ecosystems, but also the relatively recent syndromes of fuels reduction via prescribed burning and mechanical removal of biomass that serves as fuel; fire suppression tactics, including the wide firelines created by bulldozers and the aerial application of chemical fire retardant; and the challenges of post-fire restoration of landscapes, habitats and plant populations. We will examine these topics in this session, as well as taking a more nuanced look at the varied ways that plants adapt to fire through avoidance, resprouting, and long term seed banks dependent on fire cues for germination.
Session details
Plant ScienceGrazing & Rare Plants Compared to landscape- or animal-grazing interactions, there is relatively little specific work that has gone into the rare plant-grazing interaction. In conservation work, “grazing” is often used as a blanket term, obscuring the complexity of using grazing as a management tool to promote rare plant populations. Often the specific needs of rare plant species that “grazing” could address are unique to the species and require knowledge of both the ecology of the species and an understanding of current grazing practices. Issues of scale, location, infrastructure, and goals can further make grazing management difficult, requiring alternative solutions. Current work specific to grazing and rare plants is active with examples of both successes and failures. Discussion of ongoing work and encouraging further research is important for understanding long-term rare plant management and conservation.
Session details
Plant ScienceFire & Native Plants/Habitats (restoration or otherwise)For many native plants and plant communities, fire is an essential ecological disturbance process, and the use of fire in management including indigenous land management is essential for the health and longevity of forests, chaparral and so many other plant communities in Mediterranean California. This session will explore California native flora, vegetation and human relationships to fire.
Session details
Plant ScienceInvasive Plant Impacts, Monitoring, and Restoration Invasive plants are a major threat to native plant biodiversity in California. This session will highlight cutting-edge research and new techniques to prevent introduction, and scientifically manage existing infestations, of the most damaging invasive plants in California.
Session 7 details / Session 27 details
Plant SciencePlants, Habitats & Wildlife Interactions (Science and restoration)The relationships of plants and wildlife will be explored through plant/habitat – wildlife resource monitoring, functional assessments, and wildlife – habitat analyses. The effects of management techniques, restoration, and environmental impacts on plant/wildlife relationships including of plant–pollinator, plant–frugivore (seed disperser), plant–herbivore, and other complex, interspecific ecological interactions will be discussed.
Session details
Plant ScienceBryology in California- Recent Advances in Understanding the Large Contribution of our Small Plants (mosses, liverworts and hornworts) Bryophytes (mosses, liverworts and hornworts) comprise more than 10% of California’s native plant species. This session focuses on our rapidly expanding knowledge of the floristics, biogeography, ecology and conservation priorities of these understudied but important native plants.
