Thornewood OSP

PB, JO and I scouted this preserve on 11/1/10 for our first night hike here. We started out at 5:30. There were some annoying face flies in the first stretch of the trail.

We saw two brown unidentified mushrooms on the way, and found a large spider turret. At 6:15, we reached Bridle Trail. We wanted to see what dusk would be like, so we turned left.

At 6:30, we reached a large flat area next to an old logged redwood stump. Since it was getting dark, we stopped for dinner. A few odd bird vocalizations (owls, we assume) pierced the quiet. We left there at 6:46.

I hadn’t seen any on our day scouting trip, so JO was keeping an eye out for the odd little Hyptiotes, aka Triangle Spider. Aha! Found one, around 7:00. This is the first we’ve seen on MROSD land. We recently found some at Huddart Park. This particular spider was right by the trail, in a redwood branch. Unlike at Huddart, it was on a silk line, a couple of inches out from the redwood needles.

As we were observing it, some fast, persistent toots started up, along with a few sharp cries. This was exciting for me, since we don’t hear Northern Saw-whet Owls very often. They were relatively close.

We reached the closed part of the trail at 7:18. Twenty minutes later, we were startled to find some bright green fluorescence on the side of a redwood. This was not like the scorpion kind of green around 490nm, but was more like a green laser. Under white light, it looked yellow. Other patches were hard to see under white light. There was also a small bit of orange fluorescence in an area bare of bark.

We left the fluorescence at 7:48, and found more where we had dinner.

An Ensatina sat obligingly in the middle of the trail. We also found one early Polydesmid millipede.

We reached the intersection at 8:37 and turned left to go back to the lake. The house above the lake was obvious with its lights on. We found the dried slime mold I’d seen on our previous trip, and found Ceratiomyxa fruticulosa near it.

At 9:00, there was no action on the lake, and it was perfectly quiet. On top of the signpost by the lake were two small millipedes.

We found spiders in a couple of small turrets but forgot to look for the large one we’d seen on the way in. We also forgot to look into a hole in the trail. But we found one male Calisoga sitting on the side, as well as an (probably) Arboreal Salamander’s head poking out of a hole in the trailbank!

We arrived back to the lot around 10:00.

    Really nice photo of the arboreal salamander peaking out of a moss-encrusted hole.
