Enjoying Outdoors! - What is Community Science?

Kristie Ehrhardt • November 7, 2024

Do you love to be outside and have a keen eye for making observations? If so, you might be interested in participating in Community Science! Community Science, sometimes also called citizen science, crowd science, participatory science, or civic science is a program where the public contributes their observations, research and data to better the overall public knowledge of a location or region. Definitions and uses of Community Science vary between organizations or communities but generally it is community members volunteering their time to gather information and donate their findings to a general database for public use and contribution.

 

"Citizen Science" was first used in the mid 1990’s in the United States by ornithologist Rick Bonney and in the United Kingdom by British sociologist Alan Irwin. Bonney used the term to describe projects in which amateur scientists such as birdwatchers volunteered their personal data. Irwin used the term as “developing concepts of scientific citizenship which foregrounds the necessity of opening up science and science policy processes to the public.” Interestingly, neither Bonney nor Irwin was aware of the other's work and defined Citizen Science independently. In 2014, the term made it into the Oxford English Dictionary and is defined as “scientific work undertaken by members of the general public, often in collaboration with or under the direction of professional scientists and scientific institutions.” Citizen Science may play a role in a wide range of studies including natural resource conservation, biology, ecology, health studies, astronomy as well as communications, information and media studies.

 

There are many opportunities to participate in Community Science in our region, below are a few of the larger events that you may or may not be familiar with.

 

California Department of Fish and Wildlife Invasive Species Program

The California Department of Fish and Wildlife (CDFW) Invasive Species Program which recruits the assistance of outdoor enthusiasts and concerned community members to assist invasive species monitoring and management. Those involved conduct surveys, collect data and report their findings to CDFW. With the help of many sets of eyes and a new smartphone app, CDFW hopes to get a leg up on identifying and managing invasive species in California. Some of the invasive species at the top of their list range from mammals to invertebrates and include nutria, brown-headed cowbirds, water snakes, red-eared sliders, bullfrogs, carp, piranhas, quagga and zebra muscles, channeled apple snails and New Zealand mud snails among many other species.

Bushy Lake

The Bushy Lake restoration project in Sacramento County is another example of Community Science at work. The project is an ecocultural restoration project and is located near Cal Expo on the Lower American River. The goals of the 86-acre project is to protect, enhance and restore sustainable habitats for northwestern pond turtles, California’s only native turtle, and to enhance the educational interpretation of resources in the Lower American River Parkway. And the turtles aren’t the only species benefiting from the project, there are 139 additional species that call Bushy Lake home as well. The project provides an opportunity for community service for students as well as habitat and species monitoring for private citizens. The data is collected under the Sacramento County Department of Regional Parks as part of the obligations and policies under the American River Parkway Plan.

The City Nature Challenge

The City Nature Challenge (CNC) began in 2016 as a competition between the California Academy of Sciences in San Francisco and the Natural History Museum of Los Angeles County in Los Angeles to see which city could document the most species observed during an eight-day period. The competition began as a fun and creative way to embrace and better understand urban biodiversity. During the first year over 1,000 people participated with over 20,000 observations being made. The result was outstanding with an approximate 1,600 species documented in each city with new occurrences for both locations.


The idea was too big to keep local and the following year the CNC went national and the next year international and species are now being cataloged across the globe! The CNC now an annual “bioblitz” where cities around the globe compete to see who can record the most species with the most people participating while working together toward a common goal of witnessing and sharing nature. The 2024 CNC resulted in just under 2.5 million observations with 65,682 species being observed by 83,528 participants. To see past results click here. Observations are recorded in iNaturalist and if your city isn’t registered to participate, you can still play along and record your sightings as an individual. To sign up for iNaturalist, visit https://www.inaturalist.org/.

 

The 2025 CNC will begin on April 25, 2025 at 12:00 am and run until April 28, 2025 11:59 pm. Any observations posted in iNaturalist in the Yolo, Sacramento, Sutter, Placer, Nevada, San Joaquin, El Dorado, Yuba and Amador Counties during that time will be counted toward the Sacramento Region’s total. 

 

Other well-known Community Science projects include the National Audubon Society’s Christmas Bird Count where community members document bird species and numbers annually around Christmas time and Purple Air, the largest real-time air quality database that collects air quality data using sensors on public and private property and reports the results via their website or app. Community Science creates good will in the overall community by engaging community members to notice and appreciate nature.

 

Keep an eye on our events page, Tuleyome is hosting a Bioblitz at the Woodland Regional Park Preserve on December 14, 2024. Join us so you can participate in Community Science and add your own observations to iNaturalist!

In 2020, Governor Newsom committed California to an ambitious goal: conserve 30% of our lands and coastal waters by 2030. This “30x30” initiative isn’t just about setting aside more protected areas; it’s a comprehensive strategy to protect biodiversity, expand equitable access to nature, and build resilience to climate change across California’s diverse landscapes and waters. California has made meaningful progress towards the 30x30 goal. Currently, 24.4% of our lands and 16.2% of coastal waters meet the 30x30 conservation criteria, defined as areas that are durably protected and managed to sustain functional ecosystems and the diversity of life they support. But with less than five years remaining, we still need to conserve millions of additional acres to reach this critical goal. The Power In Nature Coalition No single organization can achieve 30x30 alone. That’s why Tuleyome is a proud member of the Power In Nature Coalition; a network made powerful by the collective work of over 250 community groups, conservation organizations, land trusts, and Indigenous organizations working together to conserve and protect the diverse landscapes of California. This statewide network coordinates advocacy, identifies priority conservation projects , and ensures that 30x30 implementation protects biodiversity, fosters meaningful relationships, and partners with state agencies and diverse communities. Power In Nature works on multiple fronts: defending conservation funding in state budgets, identifying potential 30x30 projects across California, and advocating for policies that support rather than undermine conservation progress. Power In Nature has multiple regional groups to elevate geographical priorities and empower local organizations to connect state-level policy to on-the-ground conservation work in their communities. Tuleyome’s Role in Advancing 30x30 At Tuleyome, our work protecting the Berryessa Snow Mountain National Monument directly contributes to California’s 30x30 goals. We’re actively engaged with Power In Nature’s Sacramento Valley regional group, as well as the Far North and Bay Area regional groups, helping coordinate conservation efforts across our region and connecting local priorities to statewide advocacy. Tuleyome has also participated in Power In Nature Advocacy Days, where we met with state elected officials to discuss policies and legislation that further or hinder the 30x30 conservation goals. How You Can Support 30x30 Whether you’re a landowner, community member, or fellow conservation advocate, there are many ways you can support 30x30 progress. There are multiple qualifying conservation lands that have not been added to the Conserved Areas Explorer and this is one of the many ways people can get involved to help track areas protected. If you’re interested in learning more about 30x30 activities in your region, check out the Power In Nature regional groups and sign up to attend monthly regional meetings or gain access to Power In Nature’s newsletter. Most importantly, through Power In Nature, you can make your voice heard by participating in local advocacy days or contacting your state legislators to encourage their support for full funding to conservation agencies and protection of environmental review processes. California’s commitment to conserve 30% of our lands and waters by 2030 is achievable, but only if we work together to make it a reality. If you have questions about how to get involved with 30x30 or Power In Nature, don’t hesitate to reach out! Bryan Pride Tuleyome Policy Director

You might already know that the Berryessa Snow Mountain National Monument (Monument) is a wonderland for birdwatchers. With a range of habitat types from aquatic, riparian, native grassland, oak woodlands, conifer forests to subalpine the range of species found in the Monument is staggering. If you prefer to break it down by county rather than habitat, western Colusa County boasts a birders paradise in Bear Valley and Lake County offers the shores of Clear Lake. Napa County showcases Quail Ridge Reserve and Lake Hennessey. Yolo County puts forth a plethora of hot spots including Putah Creek, Lake Solano, and the Cache Creek preserve which is home to Bald and Golden Eagles, Osprey and others! And, this is just a smattering of the treasure trove for bird nerds to enjoy in the nearly 345,000 publicly accessible acres of Monument. But, how do you know where and when to go to see what? Even if you’re an experienced birder, it can be overwhelming to know where and when to begin. I know people that travel to different states to check birds off of their “life list”. I also know people, some of them are those same people, that travel all over the globe to get a glimpse of a rare bird - or maybe it’s just rare to someone from Sacramento. Either way it’s enticing and rewarding to be part of a community with a common interest. There’s almost a secret code between birders. There’s definitely a code to name abbreviations and a spiffy way to keep count if you’re recording them. There’s also a way to estimate the number of birds in a flock but if you’re just wanting to sneak up on a feathered friend near or far, how do you know where to start? Try downloading the Cornell Lab eBird app. The app lets you input your own findings as well as investigate other people’s observations. You can base your search on your location or use a near or far location that you’d like to go explore. Or, you can browse by species and see exactly where to go to find them. The eBird app uses citizen science and operates similarly to the iNaturalist app, a favorite among biologists, naturalists and other interested folks. With the eBird app, you can contribute your sightings or even sound recordings to the community platform making it the largest birding community in the world. You can also create your own lists and have the app track them for you. The app not only makes birding more inclusive and interesting for individual birders but it is beneficial for the network of scientists as well. The combined data from the app helps conservationists understand how numbers of birds shift as well as aiding in developing genetic species distribution models that show where and when birds are in the region. This information helps develop and establish better conservation strategies for individual species and collective populations of birds. The app is easy, fun and rewarding for novice and veteran birders, conservationists, scientists and ultimately the birds themselves.

The Capay Valley Almond Festival has been a regional tradition since 1915. It showcases the Esparto/Capay Valley region and was originally held in the fall after the almond harvest was complete. Years later it was rescheduled to occur on the last Sunday in February to celebrate the almond trees while in blossom. The Almond Festival is the only local celebration that not only incorporates the dazzling landscape but it also honors five Capay Valley towns: Esparto, Capay, Brooks, Guinda and Rumsey. The 21-mile route along Highway 16 covers each town, offering their own unique ambiance and activities all while celebrating the almond bloom in Yolo County. You will also find local crafts, family fun, delicious food and other entertainment at each location. A bit about California’s almond history! Much like the European Starling’s initial introduction into the United States, the first attempt at almond production in California was not as glorious as anticipated. Almond trees were first planted in California as early as 1853 using European varieties that were not adapted for our climate conditions. Most of these subpar trees were either converted into other fruit trees or used for firewood. Even though the inaugural attempt wasn’t fruitful (haha, get it?), lessons were learned about cross pollination and where to plant the next go-around. Science happened and by the 1880’s other varieties were being cultivated and during the Citrus Fair in 1886, the two varieties that are still grown today were introduced. By the 1900’s cross pollination tactics advanced and were in place and our commercial production was on its way. This combined with the fact that almond trees were productive in soils that were too sandy for other fruit trees and could be prolific without the use of much artificial water, the crop finally seemed to be destined for success. During the twenty year span between the mid 1960’s and the mid 1980’s, irrigation methods advanced and became more available to land in the San Joaquin Valley, which held ideal conditions for almond production, creating a booming industry that still remains today. In 2020, 1.25 million acres of California were in almond production. We yield 2.8 BILLION (!) pounds of almonds which provides 100% of the United States commercial supply and over 80% of the world’s demand. Almonds are in the top five most valuable California exports bringing in almost five billion dollars.
