Plants of UC's Landels-Hill Big Creek Reserve, and vicinity, southern Big Sur coastline, Monterey Co., CA, April 2-4, 2026

image
Whale Point cabin at the UC Landels-Hill Big Creek Reserve, where we were staying. The images here feature some of the familiar plants in the vicinity, and one would think I should know them better considering how frequently I have visited Big Creek over prior decades. I would appreciate any corrections to my errors in the tentative attempts at identification by a marine zoologist.

The flowers here are island morning glory (Calystegia macrostegia), family Convolvulaceae.

The California bay (also known as California laurel, bay laurel, or Umbellularia californica), has extremely strong tasting nuts full of pungent oils, like the leaves, but can be baked for an interesting and less strong snack for the adventurous (see source). The tree is best identified by one's nose by smelling a leave, which are used by Californians as a stronger version of the familiar Mediterranean bay leaf (although one should be cautious with seasoning if serving to guests, some of whom might be senstitive to the California bay leaf). - Source: reprinted from Margit-Roos Collins' book, The Flavors of Home at the forage website

California lilac (Ceanothus thyrsiflorus and C. spp.) is a dominant bush to tree-like colorful plant (Rhamnaceae) within the coastal region of Big Creek. Former Big Creek steward, Feynner Arias, told me that he suspected it had been encroaching inland within the canyons relative to coastal redwoods, likely due to warming climate trends and recent forest fires.

The most common deer seen along the Big Sur coastline is the Columbian black-tailed deer (Odocoileus hemionus columbianus), although this is not the only subspecies of the mule deer in this area. The California California mule deer is also present. The black-tailed deer's (O. h. hemionus) is wider and has mostly black on the top, and the adult deer is smaller, and has a darker coat. The tail of the California mule deer has a larger rump patch and a thin, white tail with a black tip. These are two of the currently recognized subspecies of the mule deer (see source) The California mule deer has the broadest range in western North America, from Alaska to Baja California Sur, Mexico, but the black-tailed deer is the common mule deer in coastal regions to just north of Vancouver Island in British Columbia, Canada, where it is replaced by the Sitka black-tailed deer (O. h. sitkensis) on the coast to the north. - Source: WAFWA Mule Deer Working Group, 2023/a>

Leaves of three, let it be! Poison oak (Toxicodendron diversilobum) thrives in most of the Big Creek Reserve. According to Wikipedia, about 80 percent of humans are sensitive to its toxicity, typically developing immune-mediated skin inflammation known as contact dermatitis. However, it is eaten by the black-tailed deer, California ground squirrels, and western gray squirrels, and is apparently rich in phosphorus, calcium, and sulfur. Birds eat its berries and seek protection among its cover. - Source: Wikipedia article on poison oak

The old man's beard (or lace) lichen (Usnea spp., or Ramalina menziesii) is a fruticose lichen that thrives in the coastal fog belt of the Big Sur coastline.

California hedgenettle (Stachys bullata) is a member of the mint family (Lamiaceae), along about 7,000 other species including many noted for their culinary uses such as basil, rosemary, sage, oregano, thyme, and lavender. These all have square stems, which is not unique to the mint family but its species are by far the most commonly encountered square-stemmed plants, unless one happens to frequently encounter figworts, St. John's worts, bedstraws, willowherbs, or four-angled spikerushes.

The sticky monkey-flower (Diplacus aurantiacus) is native to the West Coast, from southwestern Oregon to California's Central Coast. It belongs to the lopseed family (Phrymaceae).
image
The sticky monkey-flower plant has a close mutualistic relationship with the checkerspot butterfly, Euphydryas chalcedona, providing it with its principle food source, and with its distribution corresponding to the life cycle of the butterfly (Mooney et al., 1981).
image
The sticky monkey-flower gets the first part of its name because its leave are covered with a resin that helps the plant resist grazing by insects and also helps it resist desiccation. It gets the second part of its name because its flower looks a bit like a smiling monkey.
image
A blue dick (Dipterostemon capitatus), apparently also known by other common names including wild hyacinth or purplehead. It is native to California and multiple other western states, and also northwestern Mexico.

The coffee fern (Pellaea andromedifolia), is a California-native cliffbrake fern that is drought and sun tolerant. According to Wikipedia (see source), some coffee ferns are diploid and reproduce sexually, while others reproduce from a gamete that is not fertilized. asexually growing into a triploid or tetraploid fern. - Source: Wikipedia

Rubus ursinus, the California blackberry, which is mostly found throughout California and west of the Cascade mountain range in Oregon and Washington, although it can also be found as far east as Idaho, and further north and south. It is popular as a native plant that does well in gardens (calscape.org).

The island morning glory (Calystegia macrostegia) thrives on the coast of California between Monterey and San Diego.
image
The island morning glory attracts various insects with its abundant nectar and pollen, especially the native bindweed turret bee (Diadasia bituberculata, but this looked like a fly to me.

It has broader black stripes and a pale whitish color compared to the western tiger swallowtail (Papilio rutulus), which is yellow with thinner black stripes.
