A positive mural, reflections and an eyeball.

Yesterday morning, as I walked through Little Italy to photograph that cool Mona Lisa freeway on-ramp mural (my previous blog post), I discovered some additional artwork in the vicinity of State Street and Fir Street.

The large mural on the side of a residential building is clearly seen by motorists heading down Interstate 5. It contains a positive message. Colorful scenes encourage people to get out of their cars and jump on a bicycle or public transit.

San Diego Audubon Society’s fun Bird Festival!

People enjoying the annual Bird Festival at Marina Village have walked to the San Diego River Estuary where many aquatic birds congregate.
People enjoying the annual Bird Festival at Marina Village have walked to the San Diego River Estuary where many aquatic birds congregate.

Today during my walk I encountered of group of enthusiastic birders at the San Diego River Estuary. These folks were all participating in the San Diego Audubon Society’s annual Bird Festival, which takes place this weekend at the nearby Marina Village Conference Center.

Later during my walk I visited the Bird Festival’s registration room, where anyone can purchase dozens of different birdwatching and reference books, plus other gifts. A friendly lady informed me that the San Diego Audubon Society has about three thousand members! During the Bird Festival and throughout the year, members can go on all sorts of field trips around San Diego County, and take every sort of bird-related class imaginable.

Members and volunteers are also involved in working to restore critical bird habitat in Mission Bay! I blogged about that a couple years ago here!

Do you make your home in San Diego? Do you love birds? Then you probably should join the Audubon Society! Here the local chapter’s website, where you can also learn more about the very cool Bird Festival, which continues through tomorrow!

The San Diego Audubon Society offers many birdwatching opportunities. The organization also has a conservation program.

Sea Grant California exhibit at the Dockside Market.

These friendly people with Sea Grant California showed me all sorts of fascinating creatures that reside off our coast! They encourage using locally sourced food.
These friendly people with Sea Grant California showed me all sorts of fascinating creatures that thrive off our coast! They encourage using locally sourced food.

During a walk last weekend, I headed out onto the pier just north of Seaport Village where the ever-growing Tuna Harbor Dockside Market is held on Saturday mornings. In addition to the local fishermen selling a wide variety of freshly caught seafood, I noticed one table with an interesting exhibit. Folks were demonstrating a few of the many different sea creatures that can be caught off San Diego’s coast.

I learned this display was created by Sea Grant California, an organization that connects government agencies, California universities, nonprofit organizations, local businesses and residents in our coastal community. Their mission is to conduct impartial research, disseminate knowledge, encourage best practices for environmental stewardship and optimize sustainable economic development.

Lots of people on the pier were checking out the live marine creatures on display, and learning which species are most common in the Pacific Ocean off our coast. I was told that most of San Diego’s commercial fishermen are conscientious and highly responsible. There are about 131 commercial fishing vessels licensed in the county. Many are based in Tuna Harbor, which occupies a picturesque stretch of San Diego’s Embarcadero.

In addition, I learned that the Port of San Diego is testing an aquaculture project at the end of one of Tuna Harbor’s docks. The port’s Oyster Nursery Research Project is part of an expanding effort to try out new Blue Economy technologies in San Diego Bay. The concept of a Blue Economy is to use innovative methods to maximize resources that are locally available in a sustainable and environmentally friendly way.

Very cool!

Volunteers restore habitat in San Dieguito River Valley!

Hard-working volunteers remove non-native vegetation in a small part of the San Dieguito River Valley.

Today I happened upon a bunch of energetic volunteers working to restore habitat in the San Dieguito River Valley! They were removing non-native vegetation near the Sikes Adobe Historic Farmstead!

Lots of invasive, rapidly growing wild mustard appeared to be the main problem. I also learned from a friendly San Dieguito River Park ranger that mustard is highly flammable, much more so than California coastal sage and chaparral plants that are native to our arid region.

Today’s work, coinciding with Family Volunteer Day, was an effort of several organizations, including the San Dieguito River Valley Conservancy. Their mission is to implement the vision of the San Dieguito River Park, a greenway that stretches all the way from Volcan Mountain near Julian to Dog Beach in Del Mar! Their conservation and educational programs, along with their purchases of land in the River Park planning area, will ensure that the beautiful San Dieguito River Valley will be a rich and healthy natural treasure for many lifetimes to come!

Cool environmental mural on Commercial Street.

Cool artwork painted by Dolan Stearns for the PangeaSeed Sea Walls: Murals for Oceans project in 2016 depicts the harmful presence of non-biodegradable plastic trash in the oceans.

I got off the Orange Line trolley the other day to capture photos of some cool street art on Commercial Street just east of 20th Street.

Like many other PangeaSeed Sea Walls: Murals for Oceans artwork that one can spot around San Diego, this one has an environmental message about taking care of the ocean. The mural, which illustrates the harmful effects of plastic pollution on marine life, was painted in 2016 by Dolan Stearns.

The left side of the mural shows an ugly yellow head spewing pollution into the water.

How to create 3D printed intertidal organisms!

The Visitor Center at Cabrillo National Monument has a cool exhibit of 3D printed intertidal organisms. An explanation is provided of how the tide pool animal models were created, and shows how the general public and interested educators can easily access essential resources via a dedicated website!

Student curriculum, simple instructions and the 3D Cabrillo biomodel .STL files library (and a link to raw Autodesk files) are all found here.

For 3D Cabrillo and the particular models seen in this exhibit, free imaging software and an iPad were used to capture images of intertidal organisms preserved by La Jolla’s world-renowned Scripps Institute of Oceanography. After models were edited on a computer using design software, they were sent to a 3D printer at the San Diego Central Library’s Innovation Lab.

This program was adapted from the Scan Our Seas project created by Dr. Andrew D. Thaler.

Do you know of any school students who’d like to learn more about marine biology, the environment and technology? This is definitely a very cool (and fun) project!

Many colorfully painted 3D printed models of intertidal organisms are on display inside the Visitor Center.

I noticed during my visit to Cabrillo National Monument today that troops of Boy and Girl Scouts were busy around the park cleaning up chewing gum and other trash!

This very cool volunteering event was part of National Public Lands Day. It was also an opportunity for Scouts to earn special badges and enjoy a free lunch with park rangers!

Wow! Great job Scouts! Your positive outlook and dedication to community service has made San Diego even more beautiful! So here’s a big Thank You!

Scouts helping to remove gum and trash were awarded a Scout Ranger Patch, and enjoyed a complimentary lunch with Park Rangers!
