Lovin’ Los Altos

Los Altos (11/7/20) Anson Davalos

Little girls love pretty things, so it wasn’t surprising that Anson Davalos’ girls would become fall color spotters like their daddy.

They enjoyed a walk through downtown Los Altos, last week, where Chinese pistache (Pistacia chinensis) are lining the streets with their bright orange, red and – a little girl’s favorite color – pink.

Autumn has descended to northern California’s urban forests with peak color lighting up Sacramento, Davis, Walnut Creek, Danville, Pleasanton, Los Altos, Saratoga, Campbell and San Jose.

Color Dips into Silicon Valley

Saratoga is on the western edge of the Santa Clara Valley (better known as Silicon Valley).

This lovely bedroom community is forested with colorful exotic trees, though if you drive State Route 9 up into the Santa Cruz Mountains toward Big Basin, it’s not long before you pass through Near Peak bigleaf maple, as Vishal Mishra found this past weekend.

Pure Purisima

Bigleaf maple, Purisima Creek Redwoods Preserve (11/6/20) Sam Reeves

Purisima Creek in San Mateo County was once my stomping grounds. I grew up on the San Francisco Peninsula and Purisima Creek Redwoods Preserve was just over the hill in Half Moon Bay.

I haven’t been back in years, but as a Boy Scout I hiked its trails, endlessly. So when Sam Reeves sent these photos, memories of my youth at Purisima came flooding back.

As Sam correctly reports, “Coastal California has a very different set of fall colors, but it’s definitely there for the taking.  The maples in the redwood forest have created a very nice ground canopy of color.  Bigleaf maple leaves were everywhere in the creekbed, on the trail, among the fern groves, and scattered about the hillsides.”

What you’re seeing in Sam’s photographs is fairly typical of fall color along the San Francisco Peninsula’s mountains. Bigleaf maple, poison oak, black oak, red alder, and creek dogwood are the foliage that provide spots of color near drainages.

Sam admits he’s been CaliforniaFallColor.com user for quite some time, but finally got fed up with being a lurker and decided it was time to post a report.

We’re glad he did, as it was a walk down memory lane for me, and he scores a First Report for Purisima Creek!

Late Autumn Storms Pave Silicon Valley With Gold

Gingko biloba, Mountain View (12/5/19) Vishal Mishra

As if the Silicon Valley wasn’t already paved with gold, late autumn is truly paving its streets with golden gingko leaves.

Leafless Tree Identification

Gingko biloba, San Francisco (12/6/19) Friends of the Urban Forest

San Francisco’s Friends of the Urban Forest (FUF) are “hedging bets,” this Sunday (love the pun), by leading a free walking tour of fall color remaining in San Francisco’s Mission District, regardless of predicted stormy weather.

Ben Carlson of FUF says the walk hopes to “catch the tail end of our fall colors, but on the other hand we’ll be talking about how to identify many of San Francisco’s most common deciduous species once they’ve lost their leaves altogether (looking for clues in twigs, bark, overall shape etc.).”

That’s a fascinating idea … a Leafless Tree Identification Tour. For me, it’s hard enough discerning one tree from another using their photographs, but take away the leaves? These FUF guys are good.

To participate, meet on Dec. 8 at 10 a.m. at 735 Dolores St. for the walk or CLICK HERE for more information.

Now, should you miss the walk, consider picking up a Green Christmas Tree from FUF. A $95 donation gets you a recyclable live tree to decorate. After the holidays, return the tree and it will be planted somewhere in San Francisco.

What’s pure fun about this program is that each tree has been given a name, not a number. In the above example, “Ester” (a fern pine, Afrocarpus gracilior) will be spending the holidays with her benefactor, then return to FUF to grace The City’s streets, thereafter.

For more about how to participate in this program and help green-up San Francisco’s urban forest, CLICK HERE.

Bay Area Gets Vibrant

Autumn in the San Francisco Bay Area is often best during Thanksgiving Week. Color spotter Vishal Mishra found Los Altos and Palo Alto true to form and glowing yesterday.

Landmark elm, flowering pear and Chinese pistache are still heavy with leaves, though dropping them in a steady fall.

Cupertino Gold

Cupertino has been producing high tech gold for decades. Now Gingko biloba are littering the home of Apple Corporation with fallen gold.

Deepa Yuvaraj writes she’s been sharing pictures of Silicon Valley fall color with friends for years, though just discovered CaliforniaFallColor.com, perhaps because of The Merc’s review (previous post).

Perhaps someone who works at Apple would take pictures with an iPhone of fall color inside the Apple Park campus ring. It would sure be fun to post them.

Tech Boom

Gingko biloba, Mountain View (11/17/19) Vishal Mishra

Palo Alto and Mountain View on the San Francisco Peninsula are experiencing another boom … the fall color kind.

Landmark gingko biloba and Liquidambar are carpeting Mountain View neighborhoods with yellow and pink leaves and Palo Alto is aglow at dusk with orange.

In The Middle of it All

Grasses, Camp Reynolds, Angel Island SP (9//19) Gillian Espinosa

Angel Island is in the middle of it all.

The largest island in San Francisco Bay, Angel island isn’t thought of as having much fall color, though it is loaded with native plants, many of which are winter deciduous.

Frémont cottonwood, western sycamore, black and blue elderberry, bigleaf maple, box elder, valley oak, red and white alder, creek dogwood, Garry’s oak, bitter cherry, western chokecherry, Oregon ash, and several type of willow grow on the island. Though, grasslands are what give Angel Island its autumn glow.

For time immemorial, the island’s north and east-facing slopes were covered with oak woodland, while native grasses and north coast scrub were predominant on west and south-facing slopes. Indian use of fire, California State Parks explains, extended the island’s grassland environment, restricting forest and brush to the northeast side of the island.

Then, in the 19th century Angel Island’s flora changed when native grasses (mostly perennials) were overwhelmed by aggressive European grasses whose seeds were brought in with hay. Then, most of the first-growth oak woodland was cut down for firewood.

Today, the native trees and shrubs have recovered, though they compete with exotics brought in by 19th century settlers and the military (Angel Island was an important part of the U.S. Army’s coastal defense installations and served as the Ellis Island of the West).

Most visitors to Angel Island marvel at its impressive views of the Golden Gate, San Francisco Skyline and Marin County, though turn around and you’ll see the island itself is a colorful treasure in the middle of it all.
