Between Seasons at the Sycamore Grove Park

Dates: February 21 and 25, 2017
Place: Sycamore Grove Park, Livermore, California
Length: 4.5 miles
Level: easy

The road from Livermore to Del Valle goes through a pretty valley with a large grove of sycamore trees. Each time I'd go to Del Valle I'd look at them and sigh with pleasure. So when last month I discovered there was a park there, I immediately put it on my wish list. Now all I needed was a break in the rains.
An almost incessant weather system paused for half a day two weeks ago and I hopped into the car and drove out to Livermore. By then I also had another motivation to hike there - I was planning to take the chikas' 4-H Hiking Project to that park on the following Saturday.
And I did. So the photos here are from both days: my solo hike on 2/21 and the 4-H Hiking Project hike on 2/25, to which Pappa Quail had joined too.

I start with a photo from my second hike: while I was waiting at the gate for everyone to arrive Pappa Quail got tipped by the park's personnel that a pair of red-shouldered hawks was nesting on a nearby tree and went to look for them. As I was directing the group to the parking meter and the toilets, he was taking a lovely series of photos of the pair and their nest.

When everyone was ready I called Pappa Quail and we started down the trail.

The trail doesn't go very far before it crosses Arroyo Del Valle. On both my hikes I took the time to stand on the bridge and appreciate the massive flow. The flow of Arroyo Del Valle is controlled by the Alameda County Water District. All of this flow is water let out of the Del Valle Reservoir, now that it had reached full capacity. It was very gratifying to see this.

The rains had left a more local mark too - just past the bridge there was a puddle, one of many. This one, however, had many tadpoles in it, and provided much attraction to the young hikers. One of the parents wondered aloud how do the tadpoles make it through tadpolehood in a shallow puddle, soon to evaporate. It was a simple, yet quite complex question. Naturally, if the puddle dried up before the tadpoles completed metamorphosis they would die. The question is, to the parent frogs know to lay in a large enough puddle, or do they simply take a chance? I admit that this question bugs me still.
We started on Arroyo Del Valle River Trail but soon veered to the Winery Loop Trail.

A few days before the group hike I was there on my own, checking out the trail. It was expected to rain that day, but as I got to the park the rain ceased. The trails were flowing still, like little rivers.

There a few other hikers that morning, and all of them stayed at the river trail. I pulled northwest toward the hills.  As I ascended the slope I occasionally turned to look at the view below, that would have been perfect if not for the numerous power lines that run through the park.

There were many fruit trees gone feral along my way - left unattended when the land stopped being a farm. The rose family trees were in full bloom, they looked and smelled wonderful.
Apple Tree, February 21. 
I couldn't help myself. I had to get close and take long, deep, lungful draws of the magnificent scent. Rosaceae bloom fragrance is very high on my favorite short list.

It was in that abandoned orchard area where a few days later Pappa Quail took photos of a lovely western bluebird pair. In the photo below is the female - somewhat drab, but very dignified bird.

As with most birds, when one of the pair wears fancier colors it is usually the male. This general rue is true for the bluebirds.

Less colorful birds also enjoyed the abandoned orchard.
White-breasted Nuthatch, February 25.
A bit further up the trail there is an aggregation of high power towers. Really ugly sight, they are. I tried cropping most of them out of the photo of the deer I saw grazing underneath them on my solo hike. 
Black-tailed Deer, February 21. 
The birds made good use of the power lines, ugly as they were.

There were a number of bird species sitting along the lines and a flock of pigeons crowding the top of the tower. The bird that got most of our attention as a single female kestrel that was separated from the rest of the birds.

Th seasons transformation of the East Bay hills amazes me each time anew. The first greening of the hills always fills me with joy, and this winter it had happened earlier than usual. By the time I hiked Sycamore Grove the green was as intense as I've ever seen it. A spectacular sight that I expect this year would last longer than usual.
Green Hills
The land has absorbed all the water it could and was oozing water through numerous spring holes along the hillside, and even in flat areas. Some of these spring holes were right on the trail, vigorously pumping water out.

Here is a link to the little video clip I filmed of this spring hole.

The fresh spring water run copiously above ground, turning trails into rivulets and grassland into swamps. Some of the water would collect into sink holes and disappear below ground just like that, only to re-spring at another lower altitude spring hole.

Here is a link to a little video clip I filmed of this sink hole.

I went on the little meadowlark loop trail that eventually reconnects with the Wagons Rd Trail. The break in the rain on February 21 was about to close. Dark clouds were rolling in and I quickened my pace.
Oak on the hill. 
But the clouds kept coming and drifting off, and the rain didn't resume just yet. I arrived at Cattail Pond and sat down for a snack break.
Cattail Pond
Cattail Pond is little, but makes a very pleasant place to stop. There is an observation deck there, and a bench (that I had to cover with my coat before sitting on because it was drenched). In the corner was a big sign explaining about the local ecology and the efforts of vegetation and wildlife preservation. Underneath the sign was a plastic box with an observations notebook and a pencil, and a note asking hikers to write down their observations.
And so I did: 5 turtles sitting on a log in the middle of the pond.
A few days later we saw only two turtles basking in that spot, and Pappa Quail got a nice zoom shot of them.

Pappa Quail also took a photo of a tiny orange flower he saw a bit away from the trail and showed me. It was a scarlet pimpernel - a highly invasive weed that I take great efforts in trying to eradicate from my yard. Still I post it here because it is a beautiful photo, and the flower is beautiful, a pest that it is. 
Scarlet Pimpernel, Lysimachia (Anagallis) arvensis, non-native, invasive.
Down the trail however, not far from the Cattail Pond, was a patch of California buttercup flowers.

From the pond I started descending back down the hill. I passed another pond on the way - a cattle drinking pond without any bench of educational signs.

I continued descending along a fast flowing little creek until I reached a level, open grassland area with a lovely, sweeping view of the old farmlands, the outskirts of Livermore, and the treelike that marked Arroyo Del Valle. That Dark green peak on the horizon, a bit to the right is Brushy Peak.

The sights closer to the trail were nice too: little clumps of johnney nip flowers bloomed along the trail. They were almost done blooming, in fact.
Johnny Nip, Castilleja ambigua
Somewhat further away the blue dots of the blue dicks flowers appeared in the grass. At that time the wind was picking up again and the clouds were gathering thicker.
Blue Dicks, Dichelostemma capitatum
From the higher grass flat the trail descends back to Arroyo Del Valle via an avenue of olive trees. The farm and winery that operated in this place a while ago was named "Oliviana" and many olive trees still remain on grounds. These olives, as well as a large, still working, olive orchard outside the park, are parents to many feral olives that sprout and sink roots around the East Bay, becoming yet another invasive, non-native species.

Pappa Quail continued all the way downhill where he had clear view of the sky. And what a view it was!

He also photographed one of the multitudes of ground squirrels that were running around in the park. This one was snacking in one of the feral almond trees near the old winery building.

Only four days after my solo hike the Walnut Trail was completely dry, without any sign that this trail was a makeshift creek. Only by scratching the surface with my foot I could see the moisture underneath.

Turning right back on the Winery Loop Trail we were soon by the old Winery building, a standing relic of the Oliviana days of glory. The park's personnel had tipped Pappa Quail  that a family of bobcats was residing in the ruins.

We didn't see any bobcats there or anywhere else on the hike. There were, however, plenty of birds about, including the towhee below which I photographed near the winery on my solo hike.

We continued a bit further down the winery loop trail until we arrived at a connection path back to the river trail. Near the corner was a bunch of fiddleneck flowers. They had only begun blooming and looked very fresh and beautiful.
Fiddleneck, Amsinckia sp.
A shallow pond glistened in the distance and on its surface floated two white spots that I recognised from my solo hike to be a pair of bufflehead ducks. With little prompting Pappa Quail photographed the distant couple for me.

We made it back to Arroyo Del Valle. All river crossings except for the bridges were closed, and it was clear why. Also, the trail on the other side of the river was closed because of the flooding.
Arroyo Del Valle
When I was there on my solo hike it was very soon after the flood and there were many carcasses, mostly of ground squirrels, strewn all over the place. Naturally, there were many vultures too on the ground, enjoying the feast.
Turkey Vulture, February 21
On that hike I had by myself I run into a small predicament: the river trail was deeply flooded for a good length. There was no going back or around. I had to wade in the water, and it reached my knees almost, entirely soaking my shoes and the bottom of my pants.
Flooded Trail, February 21
By the time I exited the water my wet condition hardly mattered because the rain had resumed. I quickened my pace, and the only thing I was concerned with now was keeping my camera dry. I tucked it under my jacket, but popped it out every now and then to take images of winter as it had its say at the Sycamore Grove Park.

 I love seeing storm clouds. Ever since my days of living in the Midwest I learned to appreciate the power and frightening beauty of thunder storms. We don't get storms as violent as frequently here in California, but when they do roll in I like taking the front seat and enjoy Nature's mighty display.

But on February 21 the ominous clouds passed over the park, letting down only a thin, annoying needle-like rain.
Four days later for our 4-H hike it was a brilliant, sunny day. Perfect for bird watching.

Pappa Quail photographed left and right, as the birds were active everywhere. He also took photos of the very busy acorn woodpeckers that filled the air with their raspy cries.

The park is named Sycamore Grove after the long strand of sycamore trees that grow along the river. The park's wnbsite claims this strand the biggest in Alameda County, and I completely believe it. They were, of course, completely devoid of leaves, but the signs of imminent budding were already apparent at the tips of the branches.
California Sycamore, Platanus racemosa, February 21
As I was getting near the parking lot I saw a great egret standing in ambush in the green grass. I pulled my camera from under my jacket and took a few quick shots through the rain, none of which came out good. Pappa Quail fixed the situation on the following hike - the egret was still in the same spot ... must be a good place to catch prey.
Great Egret, February 25
Upon arriving the parking lot I quickly got in my car and drove off, my feet swishing inside my flooded shoes. At the end of the group hike, however, we had plenty of time to relax by the picnic tables near the trailhead. So did one cute little titmouse.

  1. It's a beautiful place - I prefered the sunny day forcsome reason :-)

    Sighting bobcats could be wonderful...

    1. A very beautiful place indeed. I am fortunate to have it so close to my town.
      I had no illusions about seeing the bobcats. Not with a group of chatty children in tow ...

  2. really lovely hike, lots of interesting things to see...
    just one thing: the Scarlet Pimpernel is Anagallis arvensis, not Lysimachia (even in Plant List site they say that the official name is Anagallis, and it means happiness, delight. :-)

    1. Thanks, I didn't know that. I copied the name directly from the Calflora site. It might be a new change. I'll include the other one too.
