Fire followers are plants that grow in a recently burned area in much larger numbers than before a fire. In some cases the species may rarely have been observed in the area prior to the fire.

A good example of a fire follower is Poodle-dog bush (Eriodictyon parryi), which became widespread in the San Gabriel Mountains following the 2009 Station Fire.

A wet rain season also increases the population of many species. Combine a fire and wet rain season and plant distributions and populations can be dramatically altered.

Yesterday, I did a long run in the Santa Monica Mountains that included several miles of the Backbone Trail between Sandstone Peak and the Danielson Multi-use area in Sycamore Canyon. This area was burned in 2018 Woolsey Fire and there were some stunning displays of fire followers and other wildflowers.

Star lily was one of the earliest fire followers to bloom in the area and remains prevalent, but the champion fire follower at the moment is large-flowered Phacelia. Before the Woolsey Fire it would be unusual to see this plant on this section of the Backbone Trail. Now its purple-blue flowers blanket large areas along the trail.

Although not as numerous as the large-flowered Phacelia, I’ve never seen so many fire poppies along the Backbone Trail. Its orange-red color is striking and stands out sharply against the brown, charcoal-infused soil. Also more abundant this year is the vibrant yellow collarless poppy.

Here is a slideshow of some of the wildflowers seen on the run.

Back in March, a profusion of painted lady butterflies in Southern California made headlines. The colorful insects were said to be passing through the area on their way to Oregon and other points to the north.

Two months later millions of the black, orange and white butterflies continue to be seen in the West San Fernando Valley, Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch), and other areas. Recently there has been an uptick in their numbers and there have been some remarkable displays of the flyers along local trails.

There are three very similar species of “lady” butterflies in the genus Vanessa — the painted lady (Vanessa cardui), the American lady (Vanessa virginiensis) and the west coast lady (Vanessa annabella). The Canadian Biodiversity Information Facility web site has a side-by-side comparison of these species and this post on BugGuide.net compares the American lady to the painted lady.

The lady butterflies I’ve looked at closely in Upper Las Virgenes Canyon Open Space Preserve have the identifying characteristics of the painted lady (Vanessa cardui). Here are an open-wing photo and a closed-wing photo of painted lady butterflies in Upper Las Virgenes Canyon Open Space Preserve.

This three-minute slow-motion video of painted lady butterflies in upper Las Virgenes Canyon reveals their fluid, bird-like flight. The purple flowers in the video are winter vetch, an introduced plant which is also more abundant this year.

Chinese Houses Along the Sheep Corral Trail

Wildflowers continue to flourish following our wet rain season. Above average precipitation tends to produce more wildflowers, a wider variety of wildflowers, larger patches of a wildflower species, larger plants, and in some cases larger blossoms.

During the week I photographed several new “Weekday Wildflowers” on runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve. This week’s runs included Lasky Mesa, Upper Las Virgenes Canyon, and the Sheep Corral Trail.

Chinese houses, white snapdragon, yellow monkey flower, stinging lupine, and a few other species were added to the Weekday Wildflowers slideshow.

The First Snakes of Spring

When I left the house to drive over to Ahmanson Ranch, the temperature in West Hills was 92 °F. It had been five months since it was that warm.

It’s been my experience that the first hot weather of Spring is often associated with an uptick of snake sightings. Over the past seven days or so, I’d seen a very young rattlesnake and a  couple of small gopher snakes, but so far, that was it. With the warm weather, I thought I might see a snake on my run today, I just didn’t expect it to be in this manner.

Lost in thought, I was just about to the entrance of Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch) when I was startled by a large red-tailed hawk flying from right to left directly in front of me. Something long was dangling from its talons.

I stopped and watched as the raptor, fumbling with a large snake, awkwardly flew onto the top of a street light. The snake was dangling precariously from the light, and the bird seemed to be having a little trouble holding it.

The snake looked relatively heavy-bodied, and at the time I thought it might be a rattlesnake. That brought to mind a story of a hawk somehow dropping a rattlesnake into a car. However improbable, I didn’t want to approach the hawk and frighten it. I have enough problems with rattlesnakes on the ground and don’t need them falling from the sky.

I got what photos I could with my phone and headed out for a run.

You know how it is when you’ve seen a snake — anything sinuous on the trail sets off the brain’s snake alert. During my run I saw a couple of stick snakes, but no real ones. Finishing my run, I pressed the Start/Stop button on my watch and started walking across the parking lot.

What? I squinted my eyes… Was the hawk still perched on the street light? No way, more than an hour had passed!

Continuing across the parking lot, I could see the hawk was still there, but where was the snake?

Cautiously, I approached the light post. I didn’t want to agitate the hawk or stumble onto an upset rattlesnake.

Sometime during my run, the hawk had dropped the snake — a gopher snake — and was waiting to retrieve it. It lay upside down on the street — sans its head. Rattlesnake or not, the hawk had removed the dangerous bit first.

I’ll be curious to see if the snake is still in the street tomorrow.

Update April 11, 2019. The following day (Tuesday) no trace of the snake remained, but the red-tailed hawk was still there — perched on an adjacent street light. On Wednesday the bird was gone.

Wildflowers, a Waterfall, and Recovering from the Woolsey Fire

The Chamberlain segment of the Backbone Trail in Pt. Mugu State Park.

The sun had not yet risen and the poppies along Danielson Road were still tightly furled against the morning’s chill. The purl of Upper Sycamore Creek resonated in the canyon below — a wonderful tone that in recent years has too often been squelched by drought.

I was running to the Old Boney Trail and the start of the ridge that follows along Boney Mountain’s western escarpment to the massif’s huge summit plateau. Several of the Santa Monica Mountains highest peaks are on this plateau, including the range’s highest peak, Sandstone Peak.

In December I’d climbed this route to check the impact of the Woolsey Fire on the area. From the top of the ridge I’d been disheartened by what I saw. Tri Peaks and Sandstone Peak and much of the top of the Boney Mountain massif were a blackened, barren mess.

Now, three months later, I was headed back to Boney Mountain and would continue to Sandstone Peak for the first time since the fire.

Here are a few photos taken along the way.
