Managing the Invasive Volutaria (Volutaria tubuliflora) in Borrego Springs

Share

 

Borrego Springs, California is home to various plant species, but one invasive species that has been causing concern in recent years is Volutaria (Volutaria tubuliflora).


This invasive weed can quickly invade native habitats and outcompete native plants for resources. In this guide, we will discuss the impacts of Volutaria on the ecosystem of Borrego Springs, the ways in which it arrived and how to effectively manage and get rid of it.

 

What is Volutaria and How Did it Arrive in Borrego Springs?

Volutaria, also known as Volutaria tubuliflora, is an invasive weed that is native to the Mediterranean region. It is a perennial herb that can grow up to 6 feet tall, and has small, tubular flowers that bloom in the spring. The plant is known to be aggressive, spreading quickly and outcompeting native plants for resources.

It is believed that the plant was first introduced to Borrego Springs through human activity, likely as an ornamental plant. However, once it was introduced, it quickly spread to nearby wildlands through its ability to produce both seeds and underground rhizomes. This allows the plant to reproduce and establish itself in new areas, making it difficult to control and remove.

Control measures for Volutaria include manual removal, chemical control, and biological control. However, it is important to use the right control method, otherwise, the plant can quickly spread again. It is also important to monitor the area after control measures have been implemented to ensure that the plant does not re-establish itself.

Impacts of Volutaria on the Ecosystem

Volutaria, as an invasive weed, can have a significant impact on the ecosystem of Borrego Springs. The aggressive nature of the plant and its ability to outcompete native plants for resources such as water and sunlight can result in a decline in native plant populations. This can also lead to a decline in the populations of animals that rely on native plants for food and habitat, as they will have less food and shelter available. This can have a cascading effect on the entire ecosystem, altering food chains and habitats for animals.

In addition to the ecological impact, Volutaria can also have economic consequences. It can reduce the productivity of agricultural lands, decrease the value of rangelands, and negatively impact recreation and tourism in the area. Control and management of Volutaria is important to minimize its impact on the ecosystem and human activities in Borrego Springs

Managing and Getting Rid of Volutaria

Managing and getting rid of Volutaria in Borrego Springs requires a combination of methods. One of the most effective methods is manual removal, which involves physically pulling up the plants and removing the roots. Removing as much of the root system as possible is important to prevent regrowth. This method is most effective when done regularly and consistently before the plant can produce seeds.

Another effective method is the use of herbicides. Herbicides can be applied directly to the leaves of the plant, which will then be absorbed by the roots and kill the entire plant. It’s important to follow the manufacturer’s instructions when using herbicides and to be mindful of the potential effects on native plants and animals.

In addition, it’s important to prevent the spread of Volutaria by controlling its seed production. This can be achieved by removing the flowers before they have a chance to produce seeds.

It’s important to note that managing and getting rid of Volutaria is an ongoing process and requires a long-term commitment. It’s also important to work with local authorities and organizations, such as the Bureau of Land Management and the Anza-Borrego Desert Natural History Association, to coordinate efforts and ensure effective management strategies.

 

In summary, Volutaria (Volutaria tubuliflora) is an invasive weed in Borrego Springs, California that can quickly take over native habitats and outcompete native plants for resources. It is believed to have arrived in Borrego Springs due to human activity. Managing and getting rid of Volutaria requires a combination of methods such as manual removal, herbicides, and control of seed production. It’s important to work with local authorities and organizations to effectively coordinate efforts.

Marshal South and the Ghost Mountain Chronicles with Diana Lindsay

By Sunbelt Publications • June 9, 2026
A Sunbelt Spotlight with Diana Lindsay  For 17 years, Marshal South and his family lived on Ghost Mountain, a remote, waterless mountaintop in Blair Valley, now part of Anza-Borrego Desert State Park. Their life of isolation, creativity, and survival became one of the desert’s most talked-about stories. Life on Ghost Mountain From 1930 to 1947, the South family lived in a handmade home on Ghost Mountain. Marshal South wrote about their primitive lifestyle in monthly articles for Desert Magazine, drawing thousands of readers into the family’s unusual desert experiment. A Writer, Poet, and Desert Storyteller South wrote poems, novels, essays, short stories, and more than 100 pieces for Desert Magazine. His writing celebrated the silence, beauty, natural history, and healthful qualities of the desert. The Story Behind the Legend Diana Lindsay, editor of Marshal South and the Ghost Mountain Chronicles, shares the history behind the South family’s life, the questions surrounding their years on Ghost Mountain, and why the story continues to fascinate readers today. About Diana Lindsay Diana Lindsay is an award-winning author, historian, editor, and president of Sunbelt Publications.

Finding La Superba in the Night Sky

By Dennis Mammana • June 9, 2026
By Dennis Mammana Week of June 14-20, 2026  The universe is a colorful place, but stargazers are often frustrated when they cannot see the glorious colors that appear in celestial photographs. These are all quite real, so why are we unable to see them? One reason is that the color receptors of the human eye (the cones) don't respond well under faint light. They need a significant amount of energy falling on them to become active. You can prove this to yourself by trying to see colors around you in a dark movie theater. Sure, those on the screen are vibrant — that's some pretty bright light hitting your eyes — but colors throughout the dim theater appear completely muted. The second reason that astronomical photographs show beautiful colors is that camera detectors are not affected by human physiology. They can "see" colors from even the faintest of light. This is important because these colors tell us a lot about the physical and chemical properties of celestial objects. This doesn't mean you can't see color in the night sky; it just means that you'll need to find bright stars to improve your chances. One of the brightest shines high in the eastern sky after dark this week: Arcturus. Follow the handle of the Big Dipper away from its bowl, and you'll soon encounter this star. If you have good color vision, you may notice that Arcturus shines with a yellow-orange light that indicates a temperature of about 7,200 F. Now look lower toward the northeastern sky. There you'll find Vega, a nearly white star that burns considerably hotter than Arcturus — about 17,000 F. Very low in the southeast after dark, you'll find a star even more orange than Arcturus. This is Antares, the brightest in the constellation of Scorpius, glowing with a temperature of "only" 6,100 F. Aim binoculars or a small telescope toward these stars, and their colors will appear to pop. This is because the optics gather much more light than your eyes, and this helps to stimulate your color receptors. Now if you'd like to see an intensely red star, you'll need to cast your gaze high overhead. Here you'll find a star that astronomers know as Y Canum Venaticorum. Most stargazers just call it La Superba (the magnificent), so named by the mid-19th century astronomer Father Angelo Secchi. To locate it, you'll need to start at the Big Dipper; just above it appear the two most prominent stars of Canes Venatici, the hunting dogs. About two-thirds of the way between the bend of the Dipper's handle (Mizar) and the westernmost star of Canes Venatici (Chara) lies a very faint star — one you may not be able to spot with your eyes alone from near the lights of a city. What makes this star unique is that it's what astronomers call a carbon star, one of the few visible to the unaided eye. Yes, it's a giant star like Arcturus, and it's also nearing its death, but, unlike "normal" such aging stars, La Superba has accumulated more carbon compounds in its outer atmosphere. Find this faint star and aim binoculars or a small telescope toward it. I promise you'll be delighted by what you see. Visit Dennis Mammana at dennismammana.com.
