Lopez Canyon, Year Six

January's fires roared very close to Lopez Canyon, but mercifully spared it.  We got decent rain last week, so I went up to see how the place was doing. I was relieved: it is as gorgeous and fascinating as ever. The creek bed is now deeper and wider, and the eerie hills and the multi-colored sands still yield a bewilderingly diverse assortment of ancient rocks, clues to the mysteries of LA's complex geology.  

All the habitats - foothill oak woodland, coastal sage scrub, and foothill chaparral are thriving, and the invasive species are mostly in retreat. How the habitats have matured and transformed in six years! Lopez Canyon is a living laboratory for native plant succession, fire resilience, and resistance to human abuse, including dumping and the extreme weather events of global warming.  Once-and-future, it is one of the great beauty spots of Southern California.

In February of 2019 I stumbled (literally) across this sensational landscape for the first time. Here is how it looked then:

The Transformation of Lopez Canyon

The oak grove is as magical as ever, though sadly, it is still a magnet for litter and dumping.

Coast live oaks, Quercus agrifolia, are well adapted to periodic fires. The thick bark protects the cambium, which is the outer, growing part of the tree. The Creek Fire of 2017 ripped through Lopez Canyon, and adjacent Kagel Canyon and Little Tujunga Creek, from the ground up. Above, the fire seems to have burned out the base and through the interior wood of the trunk as far as head-height. But with the cambium intact, the tree is still spreading a glorious green canopy. Below is another example.

This cholla cactus is one of two left in the canyon. It was savaged by the fire and for a few years presented a very sorry sight. I am glad to see it has fully recovered and has almost doubled its height since 2019.

Hollyleaf cherries, Prunus ilicifolia, dominate the middle canyon. They were nowhere to be seen in 2019.

Elegant mountain mahoganies, Cercocarpus betuloides (foreground above) have colonized, or re-colonized, the meadow in the middle canyon. I counted about a dozen. The morning side-light doesn't do justice to their green freshness, but it does highlight their beauty of form.  

GOOD FORM: Speaking of elegance, check out this bushmallow, which caught my eye with its grace and symmetry. Normally chaparral bushmallow grows in an awkward or droopy tumble-down fashion,  but this beauty got me excited regarding the potential of bushmallow for an ornamental plant. [UPDATE: see next post for the revelation of her true identity!]

The meadow's stand of giant wild rye seems to have been scorched by last summer's blazing 100-degree temperatures. Leymus condensata (annoyingly, also called by its anagram Elymus condensata) is plentiful elsewhere up and down Lopez Canyon, but this was its largest stand. Watch this space to see if it comes back.

Toasted rye.

Blue elderberry, Sambucus cerulea, just coming out of its bundle-of-sticks winter dormancy.

Spiny redberry, Rhamnus crocea (center above), is now very plentiful in the middle canyon.

The thicket on the right, below, is fronted by the fabulous Nevins barberry, Mahonia nevinii. 

This was first specimen of these unicorns of the CFP I ever spotted. So I was cheered to see it thriving, ready to burst into flower, and spangled with morning dew-drops.

Beating out the Nevins in the stakes for the first bloom of the spring, are the golden currants, Ribes aureum. They always win, first week in February.
