May is American Wetlands Month 

by

May is American Wetlands Month, and a perfect time to take a moment to appreciate these beautiful habitats and all that they offer to wildlife and communities. 

What are Wetlands? 

A wetland is land that is covered by water—salt, fresh, or brackish—either seasonally or permanently, that functions as its own ecosystem. Freshwater wetlands include bogs, swamps, and wet prairies. Saltwater wetlands include salt marshes and mangrove swamps.  

Why are Wetlands Important? 

Wetlands are one of the most productive and biodiverse habitats on our planet. They provide important shelter and breeding, nesting, feeding, and wintering habitat for a wide range of species. In fact, while wetlands cover only six percent of the Earth’s land surface, forty percent of all plant and animal species live or breed in them and more than one-third of the threatened and endangered species in the United States live exclusively in wetlands.  

Many fish and shellfish species such as flounder, sea trout, spot, croaker and striped bass and shrimp, oysters, clams, and blue and Dungeness crabs need coastal wetlands to survive. Many birds such as ducks, geese, woodpeckers, hawks, wading birds, and songbirds in addition to mammals such as black bears, raccoons, otters, and deer, rely on wetlands for food, water, and shelter. 

Wetlands absorb excess rain or river water, so they protect communities against flooding and sea level rise. Additionally, wetlands help remove excess nutrients, toxic substances, and sediment from water that flows through them. They are so effective at improving water quality they have been referred to as the “kidneys” of a watershed.  

How do wetlands fight climate change? 

Wetlands are one of the planet’s best carbon-storing tools. When natural debris such as leaves, animal waste, and other high-carbon matter settles from the water’s surface to the bottom, it’s buried by sediment, sequestering carbon. Research indicates that coastal salt marshes can sequester approximately 1,940 pounds of carbon per acre per year, helping keep greenhouse gases out of the environment. 

We need to Conserve and Restore Wetlands 

In the past century, most wetlands have been drained, filled, and disconnected from the flowing rivers and streams that once brought them life. In California, more than ninety percent of the wetlands that once spread across the state have disappeared.  

This May, we invite you to explore a wetland near you. Observe the incredible biodiversity, enjoy the natural tranquility, and reflect upon the importance of preserving and restoring our remaining wetland habitats for the species that rely on them and the communities that they enrich. Each of us can be a voice for the wetlands.

Honoring Local Impacts of the Clean Water Act on the 50th Anniversary

by

Clean water is central to our identity and way of life on the South Coast. The health of our ocean—and the creeks, rivers, wetlands, and watersheds that flow into it—directly affects our community’s health and happiness, our economy, and the ecological richness that makes this place so unique.

This month, we’re celebrating the 50th anniversary of the Clean Water Act, which has played an important role in improving the water quality of the Santa Barbara Channel and its watersheds, as well as waterways across the nation.

Before the Clean Water Act, only one-third of America’s waterways were considered clean enough to be fishable or swimmable. Many of our nation’s waters were contaminated by sewage, oil, trash, industrial pollution, and agricultural runoff.  Rivers in some areas were so polluted that they caught on fire. In response to public outcry, in October of 1972, Congress passed the Clean Water Act to address water quality issues by regulating the amount of pollutants discharged into our natural water systems and establishing national standards for water quality.

The Clean Water Act represented a milestone in our nation’s environmental history. It took significant steps to stop dumping raw sewage and untreated industrial waste into our waters. It set a goal to restore and maintain the chemical, physical, and biological integrity of the nation’s waters for the use and benefit of everyone. It also gave every person the right to enforce the law when the government fails to protect clean water. 

Since then, Channelkeeper and other Waterkeepers across the United States have used the Clean Water Act to stop pollution, to prevent habitat destruction, and to set water quality standards that ensure our waterways are healthy for both wildlife and people to use and enjoy.

In fact, the Clean Water Act forms the backbone of Channelkeeper’s work. In 1999, Santa Barbara County had the highest number of public health warnings for poor water quality of any coastal county in California. Since then, Channelkeeper has leveraged the Clean Water Act to improve water quality along the South Coast by motivating polluters like Halaco Engineering Co., the Ojai Quarry, and Southern California Edison to clean up their operations. We have also used the Clean Water Act framework to effect policy changes to better protect our community from sewage overflows, industrial pollution, and agricultural discharges.

There is still work to be done to defend our community’s right to clean water and healthy habitats, but we hope you’ll join us in honoring the 50th anniversary of a law that has improved the health and safety of the ocean, creeks, wetlands, and rivers that we love and continues to help keep our waterways, wildlife, and community vibrant.

Monitoring Plankton to Protect Wildlife, People, and Ocean Health

by

Did you know that one teaspoon of ocean water can contain over a million living creatures called plankton?  These microscopic plants (phytoplankton) and animals (zooplankton) drift with the ocean’s currents and play a fundamental role in many ocean systems. Plankton are tiny yet vital organisms.

Phytoplankton form the base of the ocean food web. Small marine creatures like zooplankton, crustaceans, and small fish eat phytoplankton and are in turn consumed by whales, squid, and larger fish, which become food for top ocean predators like sharks.

Phytoplankton concentration is influenced by several factors, including light availability, temperature, and nutrients.

Phytoplankton produce their own nourishment using the energy of the sun in a process called photosynthesis. During photosynthesis, phytoplankton release oxygen into the water as a byproduct. Scientists estimate that about 50% of the world’s oxygen is produced via phytoplankton photosynthesis.

Phytoplankton are also responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. During photosynthesis, they consume carbon dioxide and later release it through respiration or as biomass when they die and sink to the bottom of the ocean.

.
Why Monitor Plankton?

Channelkeeper conducts plankton tows to help monitor algal blooms in the Santa Barbara Channel. When environmental conditions in ocean water change, sometimes caused by an overabundance of nutrients such as nitrogen or phosphorus from fertilizer runoff, sewage treatment plants, and other land-based sources, phytoplankton populations can grow rapidly. This is called a “bloom.” Some blooms only result in a change of the water’s color (like the coccolithophore bloom that made the ocean look milky blue in Santa Barbara a few years ago), while others can be harmful, depleting oxygen in the water, blocking sunlight, or secreting toxins. Harmful algae blooms, some of which are known as red tides due to their reddish-brown color, can sicken and kill marine wildlife and negatively affect humans who are exposed to them.

While out on our boat conducting MPA Watch surveys, our team collects samples which we send to the California Department of Health. We do this in an effort to better understand harmful algae blooms and to protect both people and wildlife from their effects.

Tiny Creatures Provide Big Insight

Monitoring plankton populations is also key to assessing the health of the marine environment. Around the world, plankton are used as indicators of the health of water due to their short life span and sensitivity to both short-term and long-term environmental changes. Studying plankton helps scientists understand many things about the ocean, such as changes in fish populations, pollution, and climate. Learning about these tiny yet vital creatures can help us better understand important ocean systems and more effectively protect wildlife and the environment.

A Snapshot of the Planktonic Community

A plankton tow is a way to collect a sample of marine microorganisms. This snapshot of the planktonic community reveals what plankton populations are flourishing, any imbalances, and can provide clues about water quality.

From the deck of our boat, the R/V Channelkeeper, our team submerges a fine-meshed net with a jar at one end to collect the plankton sample. We send it down 30 feet in the water column and pull it back up using a rope. This is called a vertical tow (as opposed to pulling the net horizontally through the water). The net is sunk and raised three times. Then, we pour the liquid trapped in the jar into a fresh bottle containing a small amount of preservative. We place the bottles in postmarked boxes and mail them to the California Department of Public Health for lab analysis. These samples are analyzed for toxin-producing species, and they reveal trends in phytoplankton distribution along the coast.

What We Sometimes Find

Diatoms
These microscopic phytoplankton plankton are a food source for zooplankton. Diatoms have cell walls made of silica and many form long chains of cells.

Coccolithophorids
Large blooms of these phytoplankton create milky white areas in the ocean that are visible from space thanks to the calcium carbonate plates that make up their cell walls.

Copepod
Considered the most numerous multicellular animals on earth, these tiny crustaceans are a food source for many other zooplankton and fish.

Krill
These zooplankton are important source of food for many marine mammals and seabirds.  They are an important part of the food web.

Meroplankton
The larvae of many bottom-dwelling invertebrates like crabs, starfish, mussels, clams, and lobsters all begin as larvae in the plankton before they settle on the bottom and become the more familiar adult creatures. These organisms are called meroplankton, because they only spend part of their lives among plankton, as opposed to holoplankton, or organisms that spend their entire lives as plankton. 

Pteropod
These gelatinous zooplankton are relatives of snails. Pteropods feed using a mucous web that they trap food particles with.

Threats to Plankton


Ocean acidification poses a significant threat to phytoplankton. When excess carbon dioxide from fossil fuel combustion is absorbed by seawater, a series of chemical reactions occur that result in the increased concentration of hydrogen ions. This increase causes seawater to become more acidic and causes carbonate ions to be less abundant. These carbonate ions are essential for calcifying organisms to build and maintain their shells, skeletons, and other structures. Scientists speculate that a more acidic ocean will cause some types of plankton to grow slower and others to grow faster, changing the balance and affecting the food web.

Plankton are also threatened by plastic pollution and microplastics billions of tiny bits of plastic, less than five millimeters in size. Plastics float, block sunlight, and do not degrade. By blocking sunlight, plastics disrupt phytoplankton’s ability to produce energy through photosynthesis, causing them to die off. Zooplankton can also consume microplastics and die from blockages in their digestive tracts. Because they are a primary food source for many marine creatures, when plankton populations diminish, many other species are affected throughout the ocean food web.

Meet MPA Watch Intern, Andrea Chagoya!

by

The Santa Barbara Channel includes a network of nineteen marine protected areas, five along the coast and fourteen surrounding the Channel Islands. Marine protected areas (MPAs), are underwater parks that provide safe havens for marine wildlife. Through Channelkeeper’s MPA Watch program, staff, volunteers, and interns collect data related to human use activities at eleven of them.

Thanks to volunteers from our MPA Watch program, we’re able to gather data at three Coastal MPAs: Campus Point MPA, Naples MPA, and Kashtayit (Gaviota State Beach) MPA. The insights gained through this community science program provide context for other scientific data being collected to monitor the health of marine ecosystems and the social and economic effects of MPAs.

This year, we are fortunate to have two interns supporting this community science program, thanks in part to a grant award from the UCSB Coastal Fund. MPA Watch interns conduct weekly surveys to ensure consistent coverage of all the coastal MPAs, conduct data entry of volunteer surveys and data quality control checks, assist with volunteer training workshops, and conduct volunteer field training sessions.

Channelkeeper has worked with some incredible UCSB student interns to help support the MPA Watch program over the years. In addition to gaining valuable experience with data collection, data management, and volunteer training, these interns also gain insight into what it’s like to work at a small environmental organization.

We’d like to introduce you to one of our extraordinary interns, Andrea Chagoya.

“Andrea is a wonderful addition to Channelkeeper’s MPA Watch program and we are lucky to have her as an MPA Watch intern this year.  She’s dedicated to marine conservation, hardworking, and has even joined us for additional Channelkeeper activities outside of her MPA Watch duties like helping out at our East Side Community Watershed Brigade Cleanup event, ” says Education and Outreach Director, Penny Owens. “We are thrilled to have her on our team.”

We took a moment to talk with her recently and learn more about her interest in the ocean and marine biology.

Tell us a little about yourself. Where did you grow up?

I grew up in Mexico, in the bordering city of Tijuana, Baja California until I was 9 years old. My family and I moved to the United States as I was entering my 4th year of elementary school, and there wasn’t a single drop of English on my tongue. All I knew how to say is “Hello, my name is Andrea’ and “yes”. Within a year I knew English. Reading has always been a passion of mine, so by 6th grade I had already read all the Harry Potter books in English, as well as other series. I am interested in aquatic biology, especially marine life. I am currently a 4th year in Aquatic Biology at UCSB. I have worked hands-on with sea turtles in Costa Rica, am an intern for Santa Barbara Channelkeeper, and will be starting to work at the Sea Center at the Santa Barbara Museum of Natural History. Other interests of mine include soccer, reading, Harry Potter, baseball, and hiking.

Why do you believe that Marine Protected Areas are important?

I believe that Marine Protected Areas (MPA) are important because we need to protect marine life as much as we can, and the purpose of MPAs is to do exactly that. Our ocean holds so many important species and ecosystems. Protecting our ocean must be a top priority.

What’s the most interesting thing you’ve seen while conducting an MPA Watch survey?

I once saw a pod of dolphins jumping around the waters of Kashtayit beach where I was conducting the KWEST transect survey with Penny Owens. They were beautiful and it was actually the first time I had ever seen dolphins. The day was so beautiful and warm, the water was so blue and glistening, and the sky was so clear that the sun shone bright in a beautiful way. The dolphins looked majestic jumping and diving in the water together as if dancing. Doing MPA Watch surveys has allowed me to see a lot of beautiful sunsets and views, but I have to say the dolphins were my favorite.

What have you learned?

I have learned a lot during my time being an MPA Watch intern with Channelkeeper. I’ve learned how to input data more efficiently, I have learned what to include in my surveys and the commentary that goes with it, I have learned when people will most likely be on the beach, I have learned how the moon’s cycle affects the tides and the amount of algae in the beach, and most importantly I have learned how relaxing and necessary our beaches are.

What do you appreciate most about the ocean?

The thing I appreciate most about the ocean is that it holds the most diverse life in the world. There are so many different species that are truly fascinating in the ocean that we know of, and so many that we don’t know of. The ocean gives us life, and so much more. To me, the ocean is the essence of planet Earth.

Connecting Kids with Nature to Spark Wonder and Inspire Environmental Sensitivity

by

If you’ve ever followed a hermit crab’s footprints across a tidepool, built a fort in the wilderness, or listened closely to a bird’s song, you understand the sense of wonder and quiet joy that activities in the wild can inspire. For kids, the natural world can be a place of curiosity, creative play, and discovery. 

A growing number of studies suggest that connection with nature has significant physical, psychological, and academic benefits for kids. Time in the wild can also inspire greater sensitivity to the surrounding world, a deeper understanding of environmental issues, and real-life opportunities to practice problem-solving. 

Channelkeeper’s education programs aim to nurture environmental awareness and stewardship in young people with the understanding that today’s youth are the decision-makers of tomorrow. Their environmental ethics are critical to our planet’s future. By fostering a connection between young people and the natural world, we hope to inspire the next generation of clean water leaders. 

To extend our discovery-driven curriculum beyond field trips and classroom visits, we’ve gathered a few fun, hands-on educational activities for young explorers and families to experience together. Learn about how water moves through a watershed and the ways in which it can become contaminated. Discover the fluid dynamics of the water cycle. In addition, we’ve included some special places to explore with activities such as rock hopping in Mission Creek at Rocky Nook Park, tidepooling at Coal Oil Point, bird watching at the Goleta Slough, and reading inspiring stories in the shade of a tree.

We hope that you share these activities with a special child in your life and enjoy a moment in nature together.

Activities:

Make a Watershed 

Have you ever wondered where water goes when it rains? In this simple activity you can make a model watershed and watch how the water flows over the land.

  • Crumple up a piece of plain office paper and then smooth it back out most of the way- it should remain a bit crumpled, showing small ridges (high points) and valleys (low points). 
  • Imagine that this paper is a section of land. Find the ridgelines (the tops of the fold-lines). 
  • Use a washable blue marker (not permanent) to color along the ridgelines on your land. The blue color from the marker will help you follow the path of the precipitation.
  • Use a spray bottle of water to create a rainstorm over your land. The goal is to create gentle sprays of mist. 
  • Spray the bottle once, and observe the precipitation. Has the water begun to move in your watershed? If not, then lightly mist again, until the precipitation starts traveling on your watershed. 
  • As your rainfall accumulates, observe the pathways where the excess rainfall travels.

Explore your watershed. With your finger, trace your stream (the path of the blue marker) all the way back up to where it starts at the top of the ridge. When you reach the top, this is the edge of the watershed for your stream and lake. Trace the entire edge of the watershed with your finger by following the ridgeline.  Everything inside, the downward-sloping area you have just outlined is the watershed for your stream or lake.

Find the Solution to Pollution 

  • Gather up 4-5 clean glass jars, masking tape, paper coffee filters, and a magnifying glass. 
  • Collect water from different sources including tap water, a creek or lake, or even the ocean making sure to label each jar with the water source.
  • Fit the coffee filters just inside the mouths of additional large, wide-mouthed jars. 
  • Take one of the water samples, and slowly pour the water through the filter into the other jar. Repeat for each water sample, pouring it into a new jar with a fresh coffee filter. 
  • Open each filter and examine it through the magnifying glass. 
  • Analyze the filters. Which filter is the most discolored? Which filter caught the most particles? Did any of the samples leave a colored residue on the filter? 
  • Discuss how the water in creeks, rivers, and the ocean can become polluted. Where do pollutants come from? 
  • A major cause of water pollution in Santa Barbara and Ventura Counties is nonpoint source pollution, or contamination that comes from more than one source. As water runoff moves over land, it picks up and carries natural and human-made pollutants into our creeks and rivers, which eventually drain into the ocean. What steps can we take to reduce water pollution in our area?

Create a Water Cycle Model

  • Use a permanent marker to draw the water cycle on a Ziplock bag (if possible, reuse a plastic bag for this activity). You can create your own interpretation of water collection, evaporation, condensation, and precipitation or follow this easy video.
  • Pour about ⅓ cup of water into the bag. You can add one or two drops of blue food coloring to the water if you choose, but it’s not essential.
  • Find a sunny window and tape the bag to the glass.
  • Check in on the water cycle bag at different times throughout the next few days. Do you see water droplets form along the bag from the condensation? Eventually, you may see streaks along the side of the bag as the droplets grow and drop down the side, representing precipitation. From there, the water will recollect and pool at the bottom, mimicking the water cycle we experience on Earth.
  • Rinse out the plastic bag and reuse it for other household needs!

Outdoor Adventures:

Visit Mission Creek in Rocky Nook Park
Rocky Nook Park is not only free to visit, its creek area is a special place to connect with nature. Practice your rock hopping skills and get to know Mission Creek’s pools while looking for tadpoles. How many different kinds of water bugs can you find? Pick up 5 pieces of trash to leave the park a little cleaner than you found it.

Low Tide Beach Walk
Check the tides and head to the beach to explore during low tide! How many creatures can you count? Can you find the wrack line, the horizontal line on the beach where kelp, driftwood, and insects collect? This accumulation area plays an important role in beach ecology. How many hermit crabs can you find in a tidepool? Can you find a sea star? Their populations are just starting to recover following a wasting disease. Be sure to leave them on the rock where you observed them! Check for low tides at Tide Predictions – NOAA Tides & Currents

Some of our favorite tidepools to explore include Tarpits Beach in Carpinteria, Leadbetter Beach in Santa Barbara, and in the Campus Point Marine Protected Area at Coal Oil Point in Isla Vista.

Watch the Birds
We’re so lucky! The Santa Barbara area has so many great opportunities to observe birds, including many species that pass through seasonally. Have you ever spotted a red tail hawk? How about a snowy egret? We challenge you to find your favorite bird! What sort of habitat does it prefer? What does it like to eat? What sounds does it make?

Visit the Goleta Slough, Lake Los Carneros, and Santa Barbara Bird Refuge for some excellent birding and check out the free ebird app for help with bird identification and cool facts!

Read books outside!

Have you ever read a book with your feet in a creek? How about under a tree? Borrow a few books from your local library or find them online and head outdoors! Some of our favorites include:

  • Once Upon a Watershed by Dianne Bennett
  • The Big Book of the Blue by Yuval Zommer
  • Deep in the Ocean by Lucie Brunelliere
  • All the Way to the Ocean by Joel Harper
  • The Little Creek that Could by Marc Angelo
  • The Lorax by Dr. Seuss
  • The Watcher: Jane Goodall’s Life with the Chimps by Jeanette Winter
