23.1 Field Ecology Course: Exploring Native Plants in High School

Jessica Anderson

El Modena High School, Orange, CA, United States

Description
This presentation will explore the design and implementation of a high school Ecological Research course focused on hands-on learning within local ecosystems. The course aims to inspire students by providing them with practical experience in ecological fieldwork and scientific inquiry, enabling them to connect directly with native and invasive plant and animal populations. Students learn a variety of field techniques for restoration and wildlife monitoring, including how to collect, analyze, and report data. This data is then used to contribute to community science projects, such as the HUBBS White Sea Bass and Get Inspired Sacramento Perch restoration programs. This approach not only teaches students scientific methodology and statistical analysis but also fosters a deeper understanding of their local environment and the importance of conservation. The presentation will offer practical strategies for other educators to create similar opportunities, empowering them to connect students with their own native plants and local ecosystems.

23.2 Learning by Doing: Education that Transforms People and Urban Habitats

Chelsea Abrahamian

Audubon Center at Debs Park, Los Angeles, CA, United States

Description
This presentation will highlight how the Audubon Center at Debs Park in northeast Los Angeles uses education and community partnerships to transform fragmented urban landscapes into thriving habitat corridors. By working with local schools, colleges, volunteers, and partner groups, the Center has developed programs that teach participants practical skills in data collection, habitat restoration, and sustainable land management. These educational experiences empower community members to apply what they learn in their own lives and communities and help us broaden our reach.

Community science initiatives also play a key role. The Marking Monarchs Project engages learners of all ages in Western monarch butterfly (Danaus plexippus) monitoring, restoration and data collection. Connecting restoration and data collection demonstrate how education can serve as both a tool for knowledge-building and a driver of ecological outcomes. Through these activities we have connected participants to an ecological story while generating data for the Monarch Larva Monitoring Project.

To encourage active participation, this presentation will include a short discussion prompt inviting attendees to reflect on ways they might adapt community-based education and science initiatives or practices in their own regions. Participants will leave with replicable strategies for designing programs that combine hands-on learning, community science, and inclusive engagement to cultivate long-term conservation stewardship.

Tesoro High School, Las Flores, CA, United States

Description
This presentation explores the powerful connections between people, native plants, and pollinators, underscoring how community-driven efforts are essential to heightening biodiversity across our landscapes. At a time when California’s native flora and its vital pollinators are facing mounting pressures, grassroots stewardship becomes a beacon of resilience and hope.

We will demonstrate how everyday individual and collective actions, such as restoring native plant communities and participating in pollinator habitat initiatives, can yield benefits for ecological health. Drawing on the shared vision of having a positive impact upon our delicate environment, the presentation highlights community science campaigns and collaborative restoration projects that have led to improved connectivity in the coastal sage scrub ecosystem surrounding Tesoro High School.

Inspiring examples showcase how local stewardship, community science, and restoration projects are producing measurable impacts throughout the Tesoro landscape and the surrounding environment: over 2,500 natives planted in the past 11 years, 600+ native plants grown from seed in the outdoor nursery, a school-wide iNaturalist Biodiversity Project, Bumble Bee Atlas and FeederWatch surveys, and 65 Eagle Scout projects are interwoven throughout Tesoro High School’s restoration sites.

By weaving human engagement with native plant stewardship and conservation strategies, communities play a pivotal role in reversing pollinator declines. Join us as we celebrate how shared efforts are forging a future where native plants and pollinators flourish in harmony with people.

Description
For decades, Northeast Los Angeles’ Elephant Hill has been both a refuge for native habitat and a veritable land-use quagmire. Accordingly, over the past 3 years, TEST PLOT, in collaboration with the Los Angeles / Santa Monica Mountains Chapter of the California Native Plant Society, has worked to support longtime conservation efforts at Elephant Hill by (1) establishing an experimental native plant garden in an invasive-choked natural upland bowl, (2) coordinating with stalwart community groups like Save Elephant Hill, and (3) holding educational programming on local flora, restoration efforts like TEST PLOT, and the relationship of native and invasive plants to fire.

At once expanding the native plant footprint in an urban setting and providing vital access to nature for a blue-collar community, this coalition of neighbors, designers, scientists and activists have successfully transformed not just 10,000 square foot of public land, but inspired larger progress of that land to become true, protected, accessible parkland.

“Our efforts may not bear fruit in one or two years, but they will over time.”— David Iniguez, El Sereno resident and US Forest Service employee

23.5 Using Crowdsourced Data to Track Post-Fire Biodiversity Trends with the Fire Followers Explorer App

Jose Esparza Aguirre

California Native Plant Society, Sacramento, CA, United States

Description
California’s ecosystems are defined by fire, yet the frequency and intensity of wildfires in recent years have raised concern. The Fire Followers project engaged community scientists in documenting post-fire plant recovery through observations submitted to iNaturalist. Through crowd-sourced data, we can compare plants observed pre- and post-fire, increase the understanding of California’s biodiversity, and collect valuable information to aid future conservation efforts.

To expand the accessibility and analytical potential of the data, we developed the Fire Followers Explorer App. This interactive tool allows us to explore plant biodiversity patterns before and after wildfire. By making complex data easily navigable, the app empowers users to identify emerging patterns, detect regional differences, and highlight species of concern for conservation. This application was developed as a collaboration between the California Native Plant Society and Avery Hill at the California Academy of Sciences. By exploring this application, we will demonstrate how crowdsourced observations can be transformed into actionable ecological insights. We will also highlight how the Fire Followers Explorer App serves as both a research platform and an outreach tool—encouraging wider participation in community science while fostering a deeper public connection to California’s landscapes.

By combining the power of community-driven data collection with open-access tools, the Fire Followers project illustrates how community science can help answer conservation questions and guide stewardship in a changing climate.
