Alex Krohn: Community Partner

A naturalist is someone who studies the patterns of nature. They seek to deepen our understanding of the natural world by observing the interconnected relationships of living things and their environments. Or in other words: Alex Krohn.

“Santa Cruz has the highest density of naturalists per capita of anywhere I’ve been, and I know the Santa Cruz Museum of Natural History plays a large role in fostering, supporting, and helping grow that community. That’s something I absolutely support, and something I’m proud to be a part of,” said Alex — a Member, program provider, and collaborative partner of the Museum.

Alex has helped to facilitate a number of loans from the Kenneth S. Norris Center for Natural History to our Museum for events such as our annual Halloween bash, Museum of the Macabre, and exhibits such as the new Mushrooms: Keys to the Kingdom Fungi, January 11-March 1, 2020. He has also led programs for the Museum as a naturalist and frequents our events as a Museum Member. As if that weren’t enough, he is a big fan of our Gift Shop. “So far I’ve done almost all my holiday shopping in the Museum’s gift shop,” he said, which we just love.

Though it is a treat to witness Alex engage on any natural history subject, he is primarily a reptile and amphibian specialist with a PhD in Evolutionary and Conservation Genomics from UC Berkeley. He loves helping connect people with all aspects of nature, both from his post as Assistant Director of the Kenneth S. Norris Center for Natural History at UC Santa Cruz and across the natural lands of Santa Cruz County.

“Santa Cruz County is a truly amazing place,” he said. “We have fantastical species found nowhere else on Earth — from half-dollar sized beetles that only fly at night during the first rains…to multiple manzanita species only present on patches of geologic beach sand that was pushed to the top of a mountain. We have towering redwoods, and sandhill chaparral and coastal grasslands, each more inspiring depending on the day of the week.”

Alex says that his favorite part of his work at the Norris Center is stewarding the collection: “I’m in charge of helping care for, organizing and digitizing more than 130,000 specimens of mostly terrestrial (but some aquatic!) species — from bryophytes to birds.”

Providing access to these collections is paramount for Alex, as is fostering an interest in nature and museums for the students he serves at UC Santa Cruz, many of whom have interned in the Education and Collections Departments of our Museum.


We are grateful to have his support as a local naturalist, important community partner, and engaged Member and friend of the Museum. Explore the wonderful work the Norris Center does by paying them a visit or learning more on their website, and visit some of the mushroom specimens we have on loan from them through our Mushrooms exhibit, opening January 11.

Fun Forms: Nature Illustration in Fungus Fair Posters

Written by Kathleen Aston, January 2020

With the Central Coast awash in new growth, this time of year finds many a fungus hunter stalking the landscape to feast their eyes, expand their minds, or feed their stomachs. For the January and February Collections Close-Ups, we went hunting in the museum’s archives to highlight stories of fungus and the people who appreciate them.  

A beloved institution for many of us, the Fungus Federation is a community organization that promotes love for and study of fungi. They welcome folks of all skill levels, from amateurs just learning what to look for, to experts helping science look more closely at the mycoflora of Santa Cruz County. In addition to educational events, workshops, and classes, they support scientific research through scholarships and grants. A federation member might be just as likely to help you learn what a particular mushroom is, as they are to advise you on how to cook it. Of course, one doesn’t always follow the other – in the words of mushroom enthusiasts, who seem equally fond of fun sayings as they are of caution – there are old mushroom hunters and there are bold mushroom hunters but there are no old bold mushroom hunters.

And they don’t just put the fun in fungi, they put on the famous annual Fungus Fair! This year’s festivities will take place from January 10 to 12 at Louden Nelson Community Center. The festivities of yesteryear can also be found in our pop up display of previous fair posters. 

The Federation’s knack for bringing people together over fungi extends to the robust local community of science and nature illustrators. This selection of posters highlights diverse strategies and styles used to depict the natural world, from watercolor to block printing to photo collage. Oftentimes the artists have been graduates of UCSC’s former science illustration certificate program. We were lucky enough to catch up with two of them.

Cynthia Armstrong’s illustration for the 2003 Fungus Fair poster is a striking combination of stark contrasts and intricate detail, highlighting a variety of fungus species ensconced within a delicate network of vines. She made it not long after completing her science illustration degree, committed to pursuing a career that dovetailed her first love, science, with her lifelong creative impulses. As an artist, Cynthia loves to show her processes – the unfolding of a subject in process recalls how the scientific exploration for answers often unfolds into new questions. As a science illustrator, she has enjoyed taking part in this process across the world, whether illustrating mammoth bones in Maine’s state museum or documenting plants for a field botanist in Panama.  

At home on the Central Coast, Cynthia loves that the redwoods are always full of opportunities to find fungus. The incredible diversity of fungus keeps her intrigued – their otherworldly and alien forms and structures are a joy to illustrate. She still regularly attends the Fungus Fair with her family, having first attended decades ago when fair founder David Arora was signing copies of his newly published classic, Mushrooms Demystified. You can catch Cynthia’s current work, including local classes, on her website.

Gay Kraeger’s work for the 2004 fair poster provides another perspective: four species of dreamily watercolored fungi chart a circle in time – guiding the viewer on what season one might be most likely to find them. Gay actually created this image years before she formally got into illustration. Her neighbors at the time, Fungus Federation members who were in the habit of hosting parties with delicious food, asked her to help illustrate a fungi cookbook they were putting together. Gay was happy to help – she’d always been in engaged with art, and natural history is her favorite subject.

Today her career continues to bring together these interests: on the one hand she teaches illustrated watercoloring journaling. Her own journaling entries are stunning. She loves to see people become more excited and aware of the world as they build the confidence to draw it. On the other hand, she and her business partner Holly Reed run an interpretive design firm called Wildways Illustrated. You can see their work all over the state, but locally they’ve contributed to signage and exhibits at places like Natural Bridges, Ano Nuevo, and the Boardwalk. She’s excited to be working on a welcome panel for Henry Cowell, where park staff made sure to request a turkey tail fungus (Trametes versicolor) as a primary feature. 


For the next two months, these posters and others from the history of the Fungus Fair will be displayed alongside a riveting traveling exhibit. We are excited to be hosting Mushrooms: Keys to the Kingdom Fungi, an exhibition developed by Jennifer Jewell and John Whittlesey.

Lisa Robinson: Museum Supporter

Lisa Robinson is a renaissance woman. As President of the board for the San Lorenzo Valley Historical Society, which owns and operates the San Lorenzo Valley Museum, she works on everything from website maintenance to managing collections and curating exhibits. Bringing together knowledge and skills from a wealth of disciplines learned over the course of a varied career, Lisa’s own work mirrors the richness of the many histories she strives to share with her community.

It was Lisa’s career as a Silicon Valley tech engineer that first brought her to the Santa Cruz Mountains. After leaving the tech world to spend more time with her family, Lisa embarked on an educational mission to support her burgeoning interest in history and art. Here she demonstrated her knack for curating coherent stories from various content – she developed her own Historic Preservation certificate from classes already being offered at her alma mater. She has applied these interests and skills to her local museum for nearly 15 years, where she began volunteering as a school programs docent. 

When asked about her favorite pieces at the SLV Museum, she struggles to choose just one. There’s a bound copy of a full year of the newspaper, “Community”, written by a high school teacher with the help of his students; the records from a local judge telling some interesting local stories; a splinter of wood from an infamous stagecoach accident; a wooden box built from the wreckage of the burned Felton Community Hall… Diverse pieces that tell many stories in different ways. The diversity of the collection is one thing she wants folks to know about–there are so many ways to connect with the past and to better consider our current times. 

Lisa’s love of history is also demonstrated in her choices for her favorite nature connections: the redwoods of Henry Cowell, the lime kilns, and an old gnarly tree–the Oldest Inhabitant, on Love Creek Road. These places are not only beautiful pieces of nature, they also tell important stories about the area’s rich history. You can’t tell human history without telling natural history, and this is why Lisa is also a supporter of the Santa Cruz Museum of Natural History. She has played a crucial role in our collaborations, and enjoys seeing co-located exhibits at the SLV Museum and the Museum of Natural History. When the same exhibits are shown in each museum, viewing things from the perspective of natural history and cultural history, we have an opportunity to learn something different in each context. 

The role of a museum, according to Lisa, is to tell stories and connect us to history, not as an abstract thing, but as something relevant and important to our contemporary lives. This can be done in many ways, but museums must strive to tell stories from as many perspectives as possible. 

This is an especially exciting challenge when curating an exhibit with community-contributed content like SLV’s upcoming annual holiday collections exhibit. Once the museum receives submissions of objects from local residents, Lisa’s job is to tie them all together in a compelling display that is both relevant and true to their past. In that, she is a shining example and we are proud to have her as part of our Museum community.

Collections December 2019: Fossils and Field Experiences

This December’s Collections Close Up features a familiar face, rather, fossil. We’re highlighting a whale ear bone that lives in our permanent fossil exhibit, currently under wraps for the final month of our Sense of Scale exhibit about earthquakes, Loma Prieta, and seismologist Charles Richter. In doing so we are also able to explore the locale from which this fossil was uncovered through a virtual field experience of the Purisima Formation. 

About the size of an oblong, to the casual observer this specimen might look like a cross between a seashell and a shriveled nut. It is in fact the ear bone of an ancient whale of unknown species. More specifically, it is a tympanic or auditory bulla, a bony capsule enclosing and protecting delicate parts of the middle ear. 

In humans, sound waves are funneled through the fleshy outer ear down the ear canal to the eardrum, where this bony protection is part of the temporal bone of the skull. This system works well in the air, but as anyone who has gone swimming knows, not so well in water. Part of the reason sound comes out garbled is because of the connection of the ear bones – your skull and your eardrums are all vibrating in response to sound waves at the same time, rather than in sequence, making it difficult to pinpoint the garbled sound’s origin. 

For cetaceans, the category of marine mammals that includes dolphins and porpoises, that just couldn’t cut it. These creatures evolved about 50 million years ago from a terrestrial mammal that looked something like a small hippopotamus. When it comes to life in the water, sound is a much more effective sense than light for communication, hunting, and finding your way. They have no external ear openings, and instead of sound waves traveling through an ear canal, they rely on pads of fat in their jaws to amplify vibrations from the water.

For a more in depth discussion of fossil whale ear bones, check out the Virginia Museum of Natural History’s paleontology blog. This article describes just one example of how scientists can learn a ton from this relatively small bone found in large creatures. In addition to shedding light on the ancient ancestors of whales, the study of these bones can illuminate how it came about that toothed whales hear best at high frequency ranges while baleen whales hear best at low frequency ranges, how it may be the case that some whales hear well at both, and more.

Our fossil was found in 1973, embedded in a chunk of Purisima Formation exposed along the Capitola Coast dating between 3 to 7 million years old. In general, museums and paleontologists are careful about how we track and provide access to information on where fossils are found in order to help preserve as much scientific information as possible while also protecting fossil discovery sites for science and the public. At the same time, this caution is balanced with a commitment to educate and share information about these same discoveries. An exciting example of educational outreach featuring the same general area where this ear bone was found is the Eastern Pacific Invertebrate Communities of the Cenozoic partnership’s Virtual Field Experiences initiative.

These virtual field experiences are richly immersive presentations of text, image, and video that serve as online excursions to different classic paleontological sites. So far there are two VFE’s, with more on the way. The first focused on the Kettleman Hills on the western edge of the central valley,  Fortunately for us, the second focuses on two areas on the central coast where the Purisima formation can easily be observed – at Moss Beach in San Mateo County and at Capitola Beach here in Santa Cruz County.

The whole project is a National Science Foundation funded effort involving several institutions, including folks at UC Berkeley and the Paleontological Research Institute, to increase public access to Cenozoic marine invertebrate fossils along the Pacific coast of the Americas. And while that means the focus is more on the fossils of creatures like clams and sea snails than vertebrate specimens like our whale ear bone, the project pages are a rich trove of information on everything from the nature of fossils, to best practices for ethical collecting, to the journey of fossils from field sites to museum collections. 

This last part is particularly exciting for us, as we work on increasing access to our own collections. And while EPICC and their VFE’s are part of an enormous, national, and multi-institutional effort, they still serve as an incredible model of how many different ways digitized collections can reach people. In the meantime, stop by the museum this month to see this ancient ear bone front and center in the Collections Close Up display.

Collections November 2019: Leaving an Impression

Sometimes nature can feel distant. As we move through the obligations and opportunities of everyday life, it can be hard to see the way that the natural world shapes the things we do and see. At other times, we can’t help it. Like when you finally have time to take that walk in the woods, or when you’re awakened by an earthquake, or your hair is tousled by the wind. Or, when someone is using nature to make a point.

One such example is this month’s Collections Close-Up: a newspaper issue printed, not on paper, but on the leaf of a tree picked in the Santa Cruz Mountains one hundred and three years ago this November. 

In 1916 newspapers were embattled by the high cost of paper. This was due in part to supply shortages caused by World War One, which were aggravated by a widespread increase in publication demand. Closer to home, the relatively new publisher of Boulder Creek’s Mountain Echo paper had another problem: his readers weren’t paying their fees.

To drive home the stark realities of the situation, Luther McQuesten printed four issues of his paper on leaves! A contemporary article from the American Printer and Lithographer ties McQuesten’s strategy to the changing of the seasons: “The advent of fall gave him an idea, and he gathered a bale of golden cottonwood leaves, which are broad and smooth and the Mountain Echo began echoing on Nature’s own papyrus.” 

Although now faded from gold to brown, this November 18th, 1916 issue still carries the news of the day. An editorial extols the virtues of Boulder Creek’s beautiful trees and babbling brooks, local families have visitors, a Winchester rifle is for sale, and D.E. French is visiting again to enjoy the scenery and collect specimens of native woods.  

The leaves proved sturdy, and our collection is not the only one that stewards one of these remarkable issues. The Boulder Creek Branch of the Santa Cruz Public Libraries has some copies on display, and the San Lorenzo Valley Museum has some in their collection as well. In fact, the San Lorenzo Valley Museum houses the original copies of the Boulder Creek Mountain Echo newspaper, both those made with “nature’s own papyrus” as well as plain old wood pulp. 

We reached out to SLV Museum Board President, Lisa Robinson, to learn more about this unique object. Lisa is a wealth of knowledge, especially when it comes to the Santa Cruz Mountains. She has also authored the “Redwood Logging and Conservation in the Santa Cruz Mountains: A Split History,” among other things.

Lest you think this leaf printing was a tired gimmick, Lisa told us that in all her years of working in museums and historical collections, she hasn’t encountered anything like this object. She highlights the technical feat of being able to print legibly on both sides of the fragile leaf. McQuesten was fully committed to people actually being able to read these nature notes – an attitude underscored by the fact that the newspaper subsequently reprinted the content of each issue on regular paper. While we don’t know exactly which of the newspapers’ presses was used for this printing, one of them still exists and is now at San Francisco’s Book Club of California.

In this image from the SLV Museum’s collections you can see the Mountain Echo office at the corner of Highway 9 and Forest St, in downtown Boulder Creek. Less than a block away from the location of the former office stands a handful of cottonwood trees (Populus fremontii). 

In 1917, an article from the Santa Cruz Evening News described the printed leaves as having brought McQuesten a “vast amount of desirable publicity” from all over the United States. Despite this notoriety, McQuestion’s stunt didn’t appear to have its desired effect: the Mountain Echo ceased publication shortly afterwards. And while the Mountain Echo is no longer covering local news nor nagging delinquent subscribers, this page of “nature’s papyrus” persists. It will be on display all this month in the Museum’s Collections Close Up, highlighting the contrast between nature we think of as natural, and the items from nature we use everyday.

If you want to explore more on related topics, stop in the Museum Gift Shop to find Lisa’s book about conservation in the Santa Cruz Mountains, and on November 23, join us for a seminar on American Indian Art, made from nature’s resources. 

November 2019: Giving Thanks and Gratitude

Ohlone Basket

In this traditional time for reflection and gratitude, we continue to be grateful for the many people who connect with nature at the Museum, and those who find ways to carry our mission beyond our walls. I am especially grateful for the opportunity to honor Native American History Month through our school programs focused on native culture, and through exciting public programs including a lecture “American Indians 101” and seminar about American Indian Art, both lead by our esteemed board member, Dr. Rebecca Hernandez of the UCSC American Indian Resource Center.

As I write our Annual Report (keep an eye out in next month’s newsletter), and think about this year’s accomplishments, I am also considering the many triumphs and changes that the Museum has undergone in its 114 year history. In this season of reflection, I am excited to also keep my eyes set on future growth and renewal–natural processes that connect all of life. From innovations in programming, growth in our garden, and renewal in our spaces, I can’t wait to share what’s to come with you all!

October 2019: Changing Seasons

As summer turns to fall, the Museum enters a season of transition as well. Gone are the summer crowds, replaced now by the energetic buzz of school groups going on their first field trips of the year. We look forward to welcoming new volunteers and docents to share their love of nature with these groups (New Docent Orientations are October 10 and 15), and to seeing the familiar faces of our dedicated docents returning after the summer break.

There has also been a transition in our staff this season. Some have moved on to new adventures, and we have welcomed new educators onto the team. After nearly four years leading the education team at the Museum, I am honored to transition into my new role as Executive Director. Just as new seasons welcome new life (migrators headed to wintering grounds, fungus soaking up first rain, etc.), this shift will signal new opportunities, approaches, and energy. As everyone settles into their new roles, and as we look to the horizon of possibilities, the Museum staff remains committed to ensuring that our services, events, and programs continue to connect people with nature in meaningful ways. We look forward to sharing this journey with our Museum community.

We are looking to continue growing our team! Click HERE to learn more about the Fund Development and Community Engagement Manager position that is currently open.

Collections October 2019: Sheer Coincidence

“It’s the end of the world!” 

Thus interrupts the drunk man from the corner of the bar, as the leading lady of Hitchock’s The Birds tries to get some answers. Outside in the sleepy town of Bodega, California, birds are everywhere. They’re massing at playgrounds, dive-bombing pedestrians — malicious attacks, intentional and murderous. It just so happens that one of the bar’s customers is an ornithologist – a baffled bird scientist who insists that birds don’t have the brain power to mount a deliberate attack – and yet, we know how serious the situation gets. 

This month’s Collections Close-Up highlights the protagonists of Monterey Bay’s real life The Birds episode, as we explore how scientists, using historical museum collections, can help us understand the natural world even when things seem bizarre or scary. 

Sooty shearwaters (Ardenna grisea) like this one are seafaring birds that spend most of their lives on the ocean. Named for their rich gray-brown plumage, the birds have gray beaks and feet with a brush of silver-white under the wings. Sooty shearwaters complete a remarkable annual migration. Each year they cross a whopping forty thousand miles round trip from nesting sites in the Southern Hemisphere to the nutrient rich waters of the north Pacific, in one of the largest mass migrations known. Here off the coast of California, you can see them from mid summer to mid fall. The shearwaters can be observed in the summer, diving down as far as 200 feet, “swimming” with their wings in pursuit of anchovies and squid.  

Sadly, sometimes they get more than they bargain for.   

One such occasion, a hallmark of local lore, was rumored to have inspired Hithcock’s horror film. Around 3:30 in the morning on August 18, 1961, thousands of sick sooty shearwaters began slamming into the coast of the Monterey Bay. As they fell against homes, cars, and streets, primarily in Capitola, they disgorged half eaten anchovies. Some frightened folks were even bitten by the crazed birds. Municipal services struggled to clean them up. 

Two years later, Alfred Hitchcock released The Birds. We know that the Capitola incident caught his eye — he even called the editors of the Sentinel to ask about the news. However, at the time of the so called “Seabird Invasion” Hitchcock was already at work on a project inspired by British author Daphne DuMaurier’s 1952 novella of the same name.  As Capitola Museum’s Frank Perry points out in a Santa Cruz Waves article on the incident, that the sad fate of the sooty shearwaters mirrored the film was simply a coincidence. And where both stories portray their avian antagonists with a malicious intent, the actual culprit is more concrete: domoic acid. 

Domoic acid is a neurotoxin produced by diatoms in the Pseudo-nitzschia genus. When these single-celled photosynthetic organisms occur in high numbers, the toxin can build up in the fish and shellfish that eat them. While it doesn’t appear to harm them, as it accumulates up the food chain to birds and mammals, it can cause lethargy, dizziness, disorientation, seizures and death. In humans, those symptoms can include irreversible short term memory loss. 

Today, when seabirds are discovered with symptoms consistent with domoic acid poisoning, swift treatment can save their lives. This was not an option in the 1960s, in part because the mechanism of the poisoning was not yet known. While scientific work on domoic acid began taking off in the 1950s, it wasn’t until a major die off of pelicans and cormorants in 1991 that researchers began monitoring the presence and effects of domoic acid in the Monterey Bay. Within a few years, scientists began suggesting that domoic acid poisoning was also at play in the 1961 event.

In 2012, a team of researchers at the Scripps Institute of Oceanography, intent on solving this scientific whodunit, examined the guts of zooplankton samples harvested in 1961, a few months before the berserk birds hit Capitola and the surrounding area. They confirmed sufficiently high levels of domoic acid-producing species of Pseudo-nitzschia diatoms had been consumed by zooplankton, who would in turn be eaten by the anchovies that poisoned the birds that ate them. As one of the researchers excitedly pointed out, historic specimens can provide answers that nothing else can, and in ways that were never imagined by the scientists who collected them.

The story certainly doesn’t end there. High levels of domoic acid in the food chain is a form of Harmful Algae Bloom. Also called HABs, these events are on the rise. HABs occur when there is a spike in the growth of algae with negative consequence for their surroundings, such as the accumulation of toxins or the depletion of oxygen. They occur when an excess of nutrients builds up in waterways, and are often associated with higher temperatures and stagnant water. Scientists are working to understand these occurrences and their complex consequences through monitoring projects across the California Central Coast and beyond

If toxic algae blooms are a little too dystopian for you, check out this year’s Museum of the Macabre for a more classic scare. We’ll be highlighting the natural and cultural history of our sometimes frightening feathered friends, from Hitchcock horror to ancient omens and beyond. Set the spooky mood by locking eyes with our very own Sooty Shearwater on special display for October’s Collections Close-Up.

Wayne Thompson: Paleontologist

Ocotober 2019

Meet Wayne Thompson: paleontologist, science educator and friend of the Museum. Wayne holds a long and rich history with us — he was the first person to receive our mastodon skull when it was brought through our doors and, today, he helps advise our Collections department.  

Wayne first came to the Museum in 1976 as a high school sophomore, eager to continue to explore the world of paleontology. A youth employment program launched by former President Jimmy Carter granted the option to work here at the Museum alongside Charles Prentice and Frank Perry, and Wayne jumped at the chance. He prepared fossils, guided guests through the galleries, and tended to our collections, among other duties.

His passion for paleontology began much earlier when, as a young boy, his father created Lost World: a 40-acre amusement park in Scotts Valley populated by curious trees and fiberglass dinosaurs. He recalls crawling inside the belly of the Triceratops with his brother, rocking the large metal I-beam like a see-saw and roaring to bring the structure to life for guests to enjoy. But fiberglass dinosaurs could only sate his interest for so long, so he also spent time in the fossil-rich hillsides of the Santa Cruz Mountains, hunting for remnants of creatures long since gone. 

Today, he’s an active researcher and science educator at Clarence Thomas “C.T.” English Middle School. He has taught at a number of California schools, holding a Master’s of Education from San Jose State University and a Bachelor’s of Applied Science, specializing in Paleontology, from UC Berkeley, among other certifications. 

He has excavated dinosaurs in the U.S. — one personal highlight was uncovering a young triceratops in the eastern Montana high desert — and researched human evolution in the Lake Turkana Basin, Africa, and planktonic foraminiferans in the Gulf of Aden with the U.S. Geological Survey. 

“But closer to home is where my passion lies,” he said. “The fossil history of Santa Cruz is just so fascinating, from mastodon skulls to shark teeth!” 

For those who want to explore the world of paleontology but don’t know where to start, Wayne recommends visiting the Museum or library, digging into the literature and connecting with scientists. 

“Start talking to people. Start spending time outside and look around your environment. Ask questions about what you see and seek answers.” 

Connecting curious minds is one of his greatest joys, he added, and welcomes all who are interested in paleontology to reach out at wthompsonctems@gmail.com

Collections September 2019: California’s Stately Grass

Grass gets a lot of attention for being green, but in California it can be gold, blue or even purple! While rolling golden hills are synonymous with many mental pictures of California, that gilded landscape is overrun by non-native species. In fact, the grasslands that cover almost a fifth of the state are dominated by plants from elsewhere. Despite this, California’s grasslands remain a biodiversity hotspot, with an immense variety of native grasses coexisting with other flora and fauna. One such species is the star of September’s close up: purple needlegrass or Stipa pulchra, California’s State Grass.

A perennial bunchgrass, purple needlegrass grows as a dense clump with tall stems that can reach higher than three feet. When it flowers in spring, these stems are topped by wispy, branching flowers. These give rise to the striking purple and red-tinged fruit or grain for which the plant is named. The grass then produces seeds that are pointed in shape with twisting bristles which act as a self-sowing mechanism, helping them to self-bury in the bare earth around the base of the mature clumped plants. Their far-reaching roots can dig down an impressive 15 feet or more into the soil, supporting the plants over a lifetime that can extend beyond 100 years.

While we’ve learned a lot about these plants, some things are still hard to know – like how widespread purple needlegrass actually was before the disruption of California’s native ecosystems. Beginning around 250 years ago, early colonists brought various changes, ranging from accidental arrivals like seeds caught in clothing to intentional alterations like the planting of new grasses for grazing cattle. In many cases this led to the introduction of non-native grasses that out-competed locals like purple needlegrass.

As we strive to understand our environment, its changes and challenges, it is critical to document species through observation and collection. This individual specimen is a window in time to the hillsides of Soquel in 1976, where it was collected by the late Randy Morgan. Beloved naturalist and teacher, Morgan was a life-long champion of Santa Cruz’s rich biodiversity heritage.

Purple needlegrass itself promotes biodiversity in a number of ways! For example, the seeds it produces, up to a whopping 227 pounds per acre, feeds a host of grassland animals. The grass itself is foraged by native ungulates like tule elk, mule deer, and pronghorns. The clumped shape of bunch grasses creates space for a whole slew of flowering plants and pollinators. Those deep reaching roots help fight erosion, maintain soil moisture, and support the growth of young oak seedlings.

Some of these same attributes that support a rich and interconnected community are also part of what makes purple needlegrass fire resilient, a hot topic in the minds of Californians everywhere. The grass’ clumping nature creates a discontinuous fuel pattern in the path of a fire. The long, water—grabbing roots of these grasses means they dry out later in the summer, making them less likely to burn during during large portions of fire season. Sadly, these benefits are often overwhelmed by the widespread presence of continuous golden carpets of shallow-rooted, invasive grasses that dry out earlier in the year than many indigenous species.

Grasses are only one of the many ingredients in the making of a California fire. For a rich discussion of fire ecology across the history and future of California, check our our upcoming panel discussion, California on Fire on September 19th. To dig in to California’s native plant communities, check out the local California Native Plant Society or garden with us at the Museum’s twice monthly Saturdays in the Soil. And now through the end of September, check out the fine details and striking hues of our preserved purple needlegrass, on display at this month’s Collections Close-Up exhibit.
