Napa Trip Day One: My friend and fellow naturalist, Roxanne and I, took Highway 113, and stopped in Davis for a little breakfast (breakfast sammich and coffee) and then we stayed pretty much on Highway 128 through Winters, past the Monticello Dam and around Lake Berryessa to the city of Angwin. At a market across the street from Pacific Union College, we met with some of my other naturalist class graduates: Pam, Patty, Elaine, and Deborah (who was the one who organized the group and hosted us at her home). It was so great to see them all again and to spend the day with them out in nature.

Just a short drive down the road from the market we went to the Pacific Union College Forest. According to the college website:
“The forested lands of Pacific Union College were once the winter camp of the Wappo tribe of California Indians, who enjoyed a bountiful supply of acorns. In 1843 the land became part of a Mexican land grant to George Yount. After the Mexican-American war, settlers used the redwoods to build homes and make grape stakes for vineyards.
Lumber was the primary industry on Howell Mountain until Edwin Angwin built his resort hotel in 1883. PUC purchased Angwin’s resort in 1909. Since then, the forest has supported the mission of the college by providing lumber for classroom buildings and residence halls, firewood for heat, and recreation in the ‘back 40’. In the 1950s, the biology faculty began to enrich student learning by studying native trees, shrubs, and wildlife.
Today the PUC Demonstration and Experimental Forest is protected by a conservation easement in partnership with the California Department of Forestry and Fire Protection (CalFire) and the Land Trust of Napa County. As such, it will always remain forest and provide learning opportunities for PUC students as well as 35 miles of recreational trails—for mountain biking, hiking, horseback riding—for students, college employees, and community members. Home to a nesting pair of Northern Spotted Owls, the rare Napa False Indigo, and some of the easternmost Coastal Redwood trees, the rich biodiversity of the PUC forest makes is especially valuable to conservationists and researchers. Our forest truly sets PUC apart and makes Angwin a unique and special place to live, learn, and grow.”
You can get a map of the trails here.
It was very chilly and breezy when we got to the forest, so we were all pretty much bundled up for the whole walk but that didn’t hamper our enthusiasm or exploration.

Because of the part of the trail system we were on, we didn’t see a lot of fungi, but the lichens were everywhere and we also found some insects and a tiny, beautiful California Slender Salamander (Batrachoseps attenuates). These little guys are nearly-endemic to northern California and breathe through their skin (so we were careful not to handle it).The one we found was snuggled down into a hole under a log and wrapped around a stick. It’s hard to describe how small they are; most people mistake them for little worms…

According to Wikipedia: “…From May to October, aestivation is the norm for this species. Unlike other members of its genus, egg-laying occurs quite early, as soon as December in the southern part of its range. Oviposition is thought to occur primarily in the tunnels of other creatures, but clusters have commonly been found on moist surfaces beneath bark, rocks, or other types of forest detritus. Clutches contain approximately five to twenty individual eggs, but five to ten different females may use the exact oviposition site; in any case, hatching occurs around March or April, somewhat later in the extreme northern part of the range.”
Such neat little dudes.
As I mentioned, we saw a lot of lichen there that we don’t get to see in the valley. I’d been looking all over for some “Toy Soldier” and “Lipstick” lichen in Sacramento, and just wasn’t finding it anywhere. They’re both lichens that stand straight up and have red “lips” at the end of their stalks. There in the PUC forest, I found several specimens of both… and was surprised by how small they are. In books, you see photos of them and they look as big as your fingers, but they’re really quite tiny.

Along with those two, I also got to see live for the first time specimens of Beaded Tube Lichen, FishboneBeard Lichen, Crabseye Lichen, Speckled Greenshield, Farinose Cartilage Lichen, Mealy Pixie Cups and others.

We also found some great specimens of Woolly Birdsnest Fungus, which unlike the Common Birdsnests we see here, are taller and covered in fine hairs.

And we got to see some Candlesnuff Fungus, also called Carbon Antlers. These were very unobtrusive-looking little “antlers” that were stickling straight up from the ground around a burl. When Deb touched them, they spewed frost-looking smoky clouds of spores all around them. [[I was so busy watching Deb flick the antlers and video the spores, that I forgot to take photos myslef! D’oh! So, I hope she shares her video with everyone.]]
Here’s a little bit of a write upon it from Wikipedia: “Specimens found earlier in the season, in spring, may be covered completely in asexual spores (conidia), which manifests itself as a white to grayish powdery deposit. Later in the season, mature ascocarps are charcoal-black, and have minute pimple-like bumps called perithecia on the surface. These are minute rounded spore bearing structures with tiny holes, or ostioles, for the release of sexual spores (ascospores).”
So, what we were seeing was the release of the asexual spores. How fascinating is that?! The fungus has two ways of reproducing: asexually and sexually. Nature tries everything.
As for mushrooms, there weren’t a whole lot on the part of the trail we traveled, but we did find a few specimens of ones like Cowboy’s Handkerchief, Milky Caps and Slippery Jacks. (Who names these things? Hah!)

I figured we walked from about 9:30 am to 2:00 pm, taking a break once for snacks. I hadn’t carried any food into the woods with me (it was all sitting in the back of the car). I wasn’t really hungry at all but Elaine shared her tea with me, and Deb gave me part of her PB&J sandwich which I thought was super-sweet of them.
I liked Elaine’s idea of taking hot tea out into the forest with you. Seems very “Downton Abbey” to me…except that I’d have to carry the tea myself instead of having servants carrying it and setting it up for me – along with petit fours and cucumber sandwiches – further up the trail. How fun would THAT be! I need to organize something like that sometime… (Where’s my Publishers Clearinghouse money!?)
I’d very much like to go to the PUC forest again sometime, and maybe attack some of the other trails. There’s supposed to be an area where there are young Redwood trees, and wetter more riparian habitat. It’s just that lo-o-o-o-n-g drive back and forth. The gals said, though, that the hotel in Winters is finally finished and that’s kind of at the halfway point between here and Napa, so that might help.
After our walk, Elaine, Pam and Patty all went back to their respective abodes, but Roxanne and I did an overnight visit at Deb’s place. Her house is very cozy and lovely, filled with art and craftwork, some of it done by her and her mom. Her mother does pottery, so there were example of her work in the plates, bowls and trays used throughout the house. And Deb does really incredible work with gourds. You can see some of them here.

The first thing we did when we got to Deb’s was sit around the kitchen table with our cellphones and cameras, and piles of field guides, and tried to make a list of everything we’d see that day. It was so much fun being surrounded by people who get as excited about identifying a “new-to-me” lichen as I do, pouring through the books, comparing photos and notes. I loved it! These ladies are so “my tribe”. Hah!
