CA Biodiversity Day

Yolo Bypass Wildlife Area

On September 7th, 2019, several members of the CCS team, including Chris Jadallah, Mackenzie Carter, Maryam Ghadiri, and Peggy Harte, participated in the 2019 California Biodiversity Day bioblitz. We joined at the Yolo Bypass Wildlife Area, located between Davis and West Sacramento. Biodiversity can be thought of as all of the different types of life on earth, from the largest mammals all the way to the smallest bacteria. California is a biodiversity hotspot, due to the wide range of habitats and climates across the state. As part of the celebration of California’s biodiversity, the California Natural Resources Agency and the California Academy of Sciences conducted 10 bioblitzes across the state. Bioblitzes are events where members of the community, naturalists, and scientists come together to record as many species as possible in a given area during a specified time frame.

The Yolo Basin was once an 80,000-acre wetland and home to a tremendous variety of species, many of which remain today. In the early 1910’s, the floodplain was converted into a bypass using a system of weirs aimed at preventing flooding in the Sacramento area. Human intervention dramatically changed the landscape, affecting wetland species and prompting ecological restoration projects. Today the Yolo Bypass Wildlife area encompasses 25 square miles of mixed-use land, including nearly six square miles of restored wetland and related habitat. For the bioblitz, participants explored the area, documenting species using cameras and cell phones.


Citizen Science from a Sailboat

by Michael P. Montgomery

Two and a half years ago, during winter quarter of my freshman year, I approached the professor of my Introduction to the Oceans class after lecture. “I like sailing,” I said. “Do oceanographic expeditions ever take place on sailboats rather than motorized ships? That would be something I would be interested in.” My professor’s answer was a gentle no; larger, engine-driven vessels are a must for the sorts of multidisciplinary cruises that define modern marine science, she said.

In hindsight, her answer makes perfect sense. Maybe it was stupid of me to ask. Nevertheless, I look back on that question now as a sign of burgeoning enthusiasm for the field that, a year later, I would declare as my major.


Congratulations to Peggy and DeAnn on a Successful Summit!

by Michael P. Montgomery

On October 1, the Center’s CCS Innovator Fellow, Peggy Harte, traveled with DeAnn Tenhunfeld to Sacramento to present at a California Expanded Learning Summit for after-school educators and administrators. Their talk, “Engaging Students in STEM through Citizen Science,” discussed citizen science’s growing role in elementary classrooms, and was attended by nearly 50 participants.

Water flows in foreground with town in backgroundWith support from the Open Rivers Fund, a program run by the Resources Legacy Fund, our Dams and Watershed Health team, Heidi Ballard, Ryan Meyer, and Chris Jadallah traveled to Missoula, Montana in July 2019 to observe and participate in the environmental monitoring associated with the removal of Rattlesnake Creek Dam. Through meetings and hands-on experience, we got an up-close look at both the promise and the challenges of monitoring collaborations focused on dam removal.

Rattlesnake Creek Dam 

Originally built to provide water for the City of Missoula in 1904, the Rattlesnake Creek Dam was first constructed as a wooden structure and later converted into a concrete one. After problems with Giardia contamination in the early 1980s, a private utility took the dam offline and the City of Missoula converted to groundwater as its primary source for drinking water.


MPAs and Citizen Science in California

Citizen and Community Science plays a special role in efforts to conserve and manage California’s ocean and coastal resources. There is a huge diversity of projects and programming operating up and down the coast, which engage the public in science and monitoring, often with direct connections to policy and management processes.


Engaging Educators in the City Nature Challenge

The Center collaborated with the California Naturalist Program, educators in the Woodland Joint Unified School District, and a variety of local nature centers and reserves to encourage participation in the Sacramento City Nature Challenge. Despite being its first year participating in this global competition (as one of more than 160 cities worldwide), over 500 people in the Sacramento region logged 9,798 observations of over 1,200 unique species using iNaturalist.


Q&A with Faculty Director Heidi Ballard

By Julie Gipple

This interview was originally published in Breakthroughs, the magazine of the University of California, Berkeley College of Natural Resources, under the title, “Q&A: When Science is Social— Alumna Heidi Ballard discusses opportunities for education and research”

What was your path to where you are today, and when did you first become involved with community and citizen science?

During my years in higher education, I became fascinated with ethnobotany—the study of cultural uses of plants—as well as the emerging fields of conservation biology and sustainable development. Across all these fields, I was most drawn to studies that involved collaborative monitoring, where different groups of stakeholders—environmentalists, resource-dependent communities, scientists, and agencies—all came together to collect data.


Final Report: Community and Citizen Science at the UC Division of Agriculture and Natural Resources

In late 2017, the Center for Community and Citizen Science began an assessment of public participation in research throughout the University of California Division of Agriculture and Natural Resources. The final report, “Community and Citizen Science at the UC Division of Agriculture and Natural Resources” is now available! Authored by our Executive Director Ryan Meyer and California Naturalist Interim Director Sabrina Drill, the report examines the status of community and citizen science at UC ANR and provides a roadmap for increasing UC ANR’s capacity for CCS.


New Report: Evaluating Knowledge to Support Climate Action

Governments and communities around the world are working to reduce their carbon footprints and mitigate the effects of climate change, but in some communities, climate action plans are stalling. A new report, “Evaluating Knowledge to Support Climate Action,” prepared by the Independent Advisory Committee for Applied Climate Assessment (IAC) with contributions from our Executive Director, Ryan Meyer, examines what it would take to develop a dynamic assessment process that helps affected jurisdictions, communities, and organizations establish pathways for climate action. Its recommendations are an important input to ongoing climate assessment and research in the federal government and elsewhere.

A role for community and citizen science

Bringing communities to the table and making sure they have the resources they need to adapt to new climate conditions is important, and community and citizen science play a critical role. This report hits upon the urgent need and exciting potential for diverse communities to participate actively in the science that supports climate adaptation and resilience. Participation through community and citizen science can address longstanding issues of equity and access that have for so long made science feel distant and irrelevant to many, even as the impacts of climate change loom larger and larger. Additionally, citizen and community science has the potential to close gaps in data-poor areas, shedding light on previously undocumented socioeconomic, ecological and health-related issues.


CitSci 2019: Where to Find Us

We’re looking forward to the upcoming Citizen Science Association (CSA) conference, right around the corner! Come catch up with us and our work at the events listed below. We are also excited to host a youth-focused community and citizen science happy hour alongside the Education Working Group on Thursday March 14th, from 6:00-8:00PM.

City Nature Challenge Comes to Sacramento Region

For the first time ever, the Sacramento Region will be participating in the City Nature Challenge. We will be competing with more than 160 cities all over the world to see who can catalogue the most nature in just 4 days! We think that joining this global effort to discover local biodiversity through citizen science is a great opportunity for the Center, and for the region.  


Sara Ludwick Presents Award-winning Poster at AGU

Congratulations to Sara Ludwick, whose poster at the AGU fall meeting entitled “Achieving Education Goals with Climate-related Community and Citizen Science,” received an Outstanding Student Presentation Award! Read on for Sara’s reflections on the experience.

I practiced my poster presentation with my family the night before my flight to Washington, D.C. The poster explored features of community and citizen science (CCS) projects that had a climate change focus. We were interested in showing how, within the context of climate change, CCS has the potential to not only generate usable data for climate science, but also to provide meaningful learning experiences for participants, depending on how these projects are designed and implemented. I thought it would be a good idea to practice talking about this work with people who had no idea what citizen science is, but their puzzled looks made me feel even more nervous about going to AGU. I spent that night fighting anxious thoughts and battling the infamous “Imposter Syndrome.”


New White Paper:

Science Identity and Agency in Community and Citizen Science: Evidence & Potential

The National Academies of Sciences, Engineering and Medicine has released a new report that takes a deep dive into research on learning through citizen science. Beyond the many challenges and recommendations it details, the report is a strong affirmation that citizen science can support both science learning and research goals. We’re proud that our work has informed this effort, including an Academy-commissioned white paper and keynote talk by Faculty Director Heidi Ballard, and Center Alums Emily Harris and Colin Dixon.


Welcome Maryam Ghadiri!

The Center for Community and Citizen Science is excited to welcome Maryam Ghadiri as the new postdoctoral fellow on the LEARN CitSci project. Maryam was recently the director of education and research at the Environmental Learning Center (ELC), a non-profit organization in Vero Beach, Florida. She worked with educators and ecologists to design, implement and evaluate different environmental education and outreach programs. 



April 26th 2019- April 29th 2019

The City Nature Challenge began as a nature-observation competition between the San Francisco Bay Area and Los Angeles County in 2016, organized around simple charge: “which city can find the most nature?” Since then, the competition has expanded rapidly, and this year more than 120 cities will participate worldwide!
