Lichen: Exploring Microecosystems in Your Backyard

Lichens are tiny farming biomes that live on rocks, soil and trees.

Fortunately, with a magnifying glass or macro setting on your smartphone, you can explore these systems within a few steps of your door.

A Lichen is a Symbiotic System

Lichen is composed of fungi, algae, and bacteria. The fungus captures plant cells, taking it inside its body where it nourishes and protects them. When the algal cells photosynthesize, they produce sugars that the fungus eats.

Very resilient, lichens have survived space experiments and can lay dormant for up to ten years in wetter California climates. Some species are over 1,000 years old!

 

What Lichens Need to Grow

Lichens need air, water, light, nutrients, and something to cling to (substrate).

Air: Like sponges, lichens absorb everything they need from nutrients to moisture. They’re so sensitive to environmental pollutants, temperature shifts and water conditions that the U.S. Forest Service uses lichen surveys as indicators of forest health, providing hot spot data and conservation priorities.

Water: Lichens don’t have the ability to regulate moisture levels (poikilohydry).  When they lack water, they dry out, go dormant and look dark. When water is available, they plump-up, look green, grow, and reproduce.

Light: The algal cells that the fungi farm need light to photosynthesize. Lichen species have different light requirements. Some prefer full sun on rocks while others like shady, cooler subclimates. Brightness and coloring are also affected by light. Species adapted to hotter and brighter conditions are generally more colorful.
 
Nutrients: Lichen nutrients include; oxygen, carbon, and nitrogen. Lichens use cyanobacteria to “fix” nitrogen from the air which is then used to organic acids and proteins. 
Species types – acidophyte & nitrophyte – that flourish or diminish under certain climate conditions are used in lichen surveys.
 
Substrate: Any non-moving object the lichen can hold onto – rocks, trees, soil, tombstones, houses, farm equipment, etc. 

Types of Lichen

 

Foliose: Leafy lichens that use tiny rhizines to attach to substrate.

Forage: Hair-like and hanging species that are eaten by animals and humans

Reproduction

Lichens have multiple reproduction methods. If they reproduce sexually (by way of fruiting bodies) they create spores. If they reproduce asexually, a powdery substance – soredia –  is released. Both methods use, wind, water, and animals to transport the newbies.

MYTH: Lichen do not harm trees. 

Other Lichen Uses & Users

Clothing, wound absorbent, diapers, model train shrubbery, and an ingredient in concrete, perfume, and deodorant. Some lichens are being studied as new sources of antibiotics and medicines.

Camouflage for; lizards, moths, tree frogs and other insects.

Insect larva camouflage

 

Nesting Material
At least 50 bird species use lichens as nesting material.

Tarplant | Spikeweed – Prolific Oil Producer & Drought-Tolerant to the Extreme

Within the California Floristic Province, there about 90 species of native tarweeds. Over millions of years, they developed to succeed in a variety of microclimates from sea level to mountain elevations. Tarweeds are part of California’s first native plants and are members of the sunflower family.

“Large swaths of undeveloped California are populated with all variety of tarweeds, because tarweeds have that logic in their DNA.” – Eric Simmons, Bay Nature Magazine

Tarweed, Hemizonia fitchii, is also known as tarplant, spikeweed, or Fitch’s Spikeweed.

They are part healthy grassland ecosystems. They’re also commonly found in areas where the soil has been disturbed.

Spikeweeds are annuals and drought-tolerant in the extreme. Seeds don’t require water to germinate!

Stalks and leaves are covered with fine hair and oil glands. A strong aroma is produced by the oil. Some folks claim it smells like turpentine, this blogger thinks it smells like eucalyptus. Tarplant oil may contain mosquito repellant properties.

Like other plants that make sticky oils, tarweeds attract certain bugs. Once they become stuck, they become carrion for predator insects that have evolved along with the tarplant, able to move about unhampered. Some of the carrion is eaten by predators while others may become nutrient sources for the plant.

Seeds are edible, like sunflower seeds. They can be eaten raw, toasted, or ground into flour. Native Americans used them to make mush. Birds and other animals also enjoy this food source.

At knee height, tarplants are eaten by grazing animals when they’re freshly sprouted, but later in the season when spikes are fully developed at the end of stem leaves, most grazers avoid them.

Flowers bloom between July – September.

Toyon – Rose Apples

Toyon, in the rose family, carries a name given to it by Native Americans and produces fruit related to apples. Because it ripens and turns bright red around the holidays, its common names are Christmas berry and California Holly.

Photo Credit: redit Miguel Vieira

Toyon’s scientific name, Heteromeles arbutifolia, means “different apple.”

There’s debate surrounding the plant’s association with the naming of Hollywood. [See link in resources.]

A California native, Toyon is an evergreen shrub. It grows from sea level to scrub oak zones up to 4,000 ft. elevation; it’s drought tolerant and accepts a variety of soil types— including clay.

FIRE

Specially adapted to flourish after fire, Toyon root crowns store carbohydrates allowing the plant to quickly send up new sprouts.

Established shrubs, reaching 8 to 10 feet in height, have lower water requirements than young plants.

MATURING FRUIT

While fruit is developing, berries contain a cyanogenic glucoside, a toxic substance, that protects them from being eaten.

As the fruit ripens, turning red, the cyanogenic glucoside moves from the pulp into the seeds.

FRUIT CONSUMPTION

Birds and some mammals, such as coyote and bear, eat Toyon berries in the fall.

For humans, the taste of fresh berries is bitter. It’s a good idea to spit out the seeds.

Heating berries before eating removes some of the bitterness.

HISTORIC HUMAN FRUIT CONSUMPTION

  • Bark and leaf tea for stomach problems and wound infections – Kumeyaay people and other Native Tribes
  • Leaf infusions – menstruation regulation – Costanoan people
  • Sun parching – Luiseno people (southern California)
  • Thirst quencher – Mahuna people
  • Wine, custard, jelly, and porridge – Spanish and American settlers

Incense Cedar, the Pencil Tree

A burned, sometimes smoldering,  Incense Cedar tree is one of the few places the Cedar Wood Wasp, lays its eggs. This insect is the only living species of its family, making it a ‘living fossil.’

Cedar is commonly used for building and fencing materials. Because the wood is pliable for gripping and resists splintering, it may be best known for its use in pencils.

Hearty, drought tolerant, and accepting of shade and sun, the tree grows at a wide variety of elevations.

Alonzo Delano – Grass Valley Champion & Gold Rush Correspondent

At age 43, after being sick with consumption, Alonzo Delano left his home and loved ones to join the mass of gold-seeking emigrants making the overland journey to California (1849). In Illinois, he sold bank stocks and commodities and lived with his wife and two children; Fred an invalid son of 16 and Harriet, a six-year-old daughter. 

After surviving the laborious trek and multiple attempts at gold mining, Alonzo settled in Grass Valley where he invested in a quartz mine and returned to banking and selling merchandise.

Drought & Fire 1854 & 1855

In 1855 two events occurred that caused great upset for the people of Grass Valley, allowing Delano to demonstrate compassionate leadership and his ability to focus a dispirited community on a hopeful future.

A drought in 1854 limited water availability. Mines struggled to keep working and miners couldn’t pay their debts. Real estate prices crashed.  The nation’s leading bank (not Wells Fargo) made an investment in a railroad that failed.

Alonzo was the Wells Fargo agent in Grass Valley. When communication from San Francisco reached him about a bank run, he opened the Wells Fargo doors on time. Climbing on top of the service counter, he declared to all, “Come on. I will pay out to the last dollar, and if that’s not enough, my own property will go.”

A month later Delano was elected the first Treasurer of Grass Valley.

Seven months went by before the second disaster struck. A terrible fire leveled at least 300 buildings, leaving thousands homeless.

“Give my love to all my friends. Tell them I was not afraid to die, and that I left the earth without ill feeling toward anybody,” Alonzo made this deathbed appeal to his wife.

“Old Block was a courageous pioneer. He loved and inspired his fellow men,” said Ezra Dane – Gold Rush writer & San Francisco Lawyer (1904-1941)

Delano’s 1849 Journal Entries Published in a Book

Traveling somewhere between 15 – 20 miles per day, the overland journey took five months. At dinnertime, Alonzo journaled about the events of his day. Sickness, starvation, thirst, and death became common experiences. Delano’s keen observations provide a window in time that shows travel conditions, food, finding water, wild animals, Indians, and the open expanse of the Sacramento Valley.

Below are selected excerpts from Life on the Plains and Among the Diggings [1849 – 1854] as well as additional Delano writings that give the reader a 318° view of Gold Rush life and early California and Nevada County.

Sickness and Bad Food

April 5th, 1849

…since the invasion of Rome by the Goths, such a deluge of mortals had not been witnessed, as now pouring from the States to the various points of departure for the golden shores of California.

On the second day [aboard steamer Revolution at St. Joseph, Missouri], amid the gaieties of our motley crowd, a voice was heard, which at once checked the sound of mirth, and struck with alarm the stoutest heart — “the cholera is on board!”

May 5th

We discovered that we had been imposed upon in St. Louis in the purchase of our bacon, for it began to exhibit more signs of life than we had bargained for. It became necessary to scrape and smoke it, in order to get rid of its tendency to walk in insect form.

Aboriginies

May 9th

I did not wonder that the aborigines were attached to their delightful country, and had it been mine, I should have defended my possessions against the encroachment of any lawless intruder.

Animal Abundance

September 14th

I learned that three miles beyond there was a spring. It was nearly sunset when I again entered the deep wood, but my anxiety to get in sight of the abodes of civilized man impelled me forward, choosing to risk a night alone in the woods, among the wild beasts which swarmed in that region, rather than not gain the distance.

First Sight of Sacramento Valley

September 17th

Ascending to the top of an inclined plane, the long-wished-for and welcome valley of the Sacramento, lay before me, five or six miles distant. How my heart bounded at the view! How every nerve thrilled at the sight! It looked like a grateful haven to the tempest-tossed mariner, and with long strides, regardless of the weariness of my limbs, I plodded on, anxious to set foot upon level ground beyond the barren, mountain desert.

Emigrants Starting the Trip Late – Fall of 1849

In addition to other calamities, many suffered from scurvy and fevers – the consequence of using so much salt or impure provisions, and while many others died, others were made cripples for life.

Rescue Efforts

Photo Credit: B.D’s world

By the earliest arrivals, in June and July, of those emigrants who reached the valley, the sufferings and destitution of those behind were made known, and the government and individuals once more extended the hand of relief. San Francisco, Sacramento City, and Marysville made large contributions, and trains loaded with provisions were dispatched to meet them.

In addition to this, traders pushed their way over the snows to Carson’s Creek, and Truckee River and even to the Sink of the Humbolt, with supplies; and although much good was done, and many lives saved, yet aid could not be rendered to all.

Societal Shifts

It was found, too, that talent for business, literary and scientific acquirements, availed little or nothing in a country where strength of muscle was required to raise heavy rocks and dig deep pits.

California proved to be a leveler of pride, and everything like aristocracy of employment; indeed, the tables seemed to be turned, for those who labored hard in a business that compared with digging wells and canals at home, and fared worse than the Irish laborer, were those who made the most money in mining.

Sutter’s Fort

And here I found myself more than two thousand miles from home, in a city which had risen as if by enchantment since I had crossed the Missouri.

Camping Near Bear River

…spreading our blankets, [we] were soon asleep, despite that howling of the cayotes all around us.

Coyotes & Dogs Frolic

These animals are of the dog species, and appear to be connecting link between the fox and wolf. They frequently go in packs, but rarely attack a man, unless pressed by hunger, which is not often, for the number of horses and carcasses of wild cattle in the valley furnish them food, and they are not looked upon as dangerous. I have seen them stop and play with dogs, which had been set upon them, returning their caresses, and showing no disposition to fight.

Oleepa Tribe

I was soon looked upon as a friend, and for aught, I know recognized as of the tribe of Oleepa. … among themselves, and with those whom they confide, a more jolly, laughter-loving, carless and good-natured people, do not exist. The air resounded with their merry shouts as we sat around their fires at night when some practical joke was perpetrated, or a funny allusion made. And they were always ready to dance or sing at the slightest intimations, and nothing seemed to give them more pleasure than to have me join in their reactions. To each other, they were uniformly kind, and during the whole of my residence with them, I never saw a quarrel or serious disagreement.

Dwindling Indian Population

…They are already dwindling, for the fire-water and rifle of the white man are doing their work of death, and five years will not pass ere they will become humbled and powerless – a wretched remnant of a large population.

Grizzly Bear in the Sutter Buttes – a Daughter Saves Her Father

About twelve miles nearly west of us, a solitary butte rises from the plain, from fifteen hundred to two thousand feet high, and whose broken, craggy and pointed ridges seem to kiss the clouds. It stands nearly in the center of the plain, equi-distant from the coast range and the Sierra Nevada.

…setting his rife against the rock, he [Peter] climbed over the ledge, when, to his horror he found himself facing a huge grizzly bear. The monster sprang upon him at once…tearing his scalp from his head, and biting him in a fearful manner… they both fell off the rock, and rolled down the hill. Peter, in the meantime, making the best use of his knife possible, inflicting several severe wounds upon his adversary.

…with the impulse of one inspired, [Peter’s second daughter] sprang towards her father…and with unerring aim, discharged it at the bear. The bullet took effect in the monster’s head, and he fell, stunned if not dead. Instantly she ran and seized her sister’s rifle, and returning placed it against the bear’s ear, and what little life remained soon passed away.

Engineering Water Movement

Where water is not found in isolated places, canals are dug, sometimes forty or fifty miles long, by which water is carried from some permanent stream along stupendous hill-sides, over ravines and gulches, and around rocks by sluices and flumes, often at vast expense of labor and money – thus arresting the skill, energy, and enterprise of the people who are delving among the mountains; hoping to acquire a competence to smooth the down-hill of life, and render old age comfortable.

Lumber; the New Riches

In the mountains, water-power is abundant for all mechanical purposes, and the noble pines, made into lumber, will form a source of wealth equaled only by its mineral treasures.

Hard Work & Failure; the Fickleness of Finding Gold

Thus the failure of the miners was felt far and wide. Wherever we turned, we met with disappointed and disheartened men, and the trails and mountains were alive with those whose hopes had been blasted.

Were the personal adventures of a moiety of the emigration of 1850 to be written, they would furnish a volume of absorbing interest, forming a sad commentary on the California gold-seeking mania, which produced more wide-spread misery than any similar occurrence in the annals of mankind.

I do not hesitate to declare that no one should emigrate, unless with the intention of making it [California] his home for life.

Gold Rush Climax

The country is large enough and productive enough to support a dense population, and individual suffering would be less if it was filled up by degrees; but one great difficulty is too many are rushing in at once before the way is sufficiently prepared for them. Now a limited number can cross the plains safely and with comfort if properly provided, but this year there are too many going at once. In addition to the stick actually required to draw the wagons on the road, a large number of cattle are being driven for market. The will generally reach the Rocky Mountains in safety – that is, there will be grass enough to sustain the cattle. But immediately on going through the South Pass the desert country commences, grass will be difficult to obtain and, I believe, impossible for so great a number. The consequences will be that the cattle of emigrant trains will die, and families will have a terra firma shipwreck, hundreds of miles from human aid. If they have money to duplicate their teams from droves, they may be partially relieved; but very many will not be able to pay the California prices which will be asked, and they will be left to get along the best way they can, which will be on foot, or die.  – True Delta – June 23, 1852

Delano – a Prolific, Eloquent Gold Rush Writer

“We have pleasure in publishing … one of the ablest correspondents it was our good fortune to secure in California in the early days of the gold discoveries. His letters to this paper were graphic, truthful, eloquent and patriotic, overflowing with generous sentiment and the spirit of manly independence so characteristic of the sons of the glorious West.” True Delta, August 12, 1852

While living in California, Delano was a correspondent for the San Francisco Daily Courier, the Pacific News, The Union, the California Farmer, the Golden Era, the Telegraph, the Hesperian, and Hutchins’ California Magazine. His work also appeared Edwin F. Beans’s History and Directory of Nevada County and the New York Times.

Life on the Plains and in the Diggings Book Review

In a time when we have plentiful water at the turn of a tap, instant worldwide communication, refrigeration, food safety, health care and emergency services, shelter from weather, planes, trains, and highway systems, it’s good to be reminded of the luxury they represent.  It’s valuable to imagine the hardships endured by the brave (or foolish!) folks who adventured to a remote and distant land in covered wagons and on foot.

The level of detail in Delano’s writing is thrilling and mesmerizing, almost like walking the trail beside him.
