December 1st, 2020 (Tuesday) 9:10-11:50 pm: 15 dead newts found, no live newts
Weather was nice, foggy earlier in the morning. No real rain in the past couple of weeks, after the initial rain. Rainfall: (MTD: 0 in; YTD: 0.93 in). Data from - http://www.weathercat.net/wxraindetail.php
@tyap and me documented 15 dead newts, 3 of them juveniles. Only one of the newts was freshly killed. It was found right in front of population study #1. I didn't include it in our project yet, I'd like to wait and see if we get a photo of it from the survey team. The rest of the newts were very dry, and were probably there for a while.

Other roadkills: 1 slender salamander, 2 unidentified vertebrates, a caterpillar, 3 Jerusalem Crickets, 1 cricket, 5 soil centipedes.
Coverage: north part - the county park parking lot till the second stop sign.
Traffic: 2 trucks, 34 cars, 2 motorcycles, 4 bikes, 9 pedestrians, and 17 cars parked by the road and in the parking lots. Some of the cars were county roads pickups.

We met the Midpen population study a few times. They haven't seen any live newts since the last rain.
The rowing club was open. All county park parking lots were open.

Hi all,
Tiffany suggested we'll have another volunteer meeting, so that she could meet everyone. We've got a few items on a tentative agenda:

South side - December 3, 2020

4 dead newts (very dry), 0 juveniles, 0 live newts
December 3rd, 2020 (Thursday)

My first patrol of the year, a lovely day for it. I got psyched out for a while by squished bay nuts in the road, so many of them, and they often look kinda like newts.

Weather: Dry and sunny in the mid 50s. No rain for many days.

December 9th, 2020 (Wednesday) 9:0-11:50 am: 5 dead newts found, no live newts
Weather was nice. No rain since the first event. Rainfall: (MTD: 0 in; YTD: 0.93 in). Data from - http://www.weathercat.net/wxraindetail.php
@karangattu and me documented 5 dead newts, 1 of them juveniles. They were all very dry. Two of the newts were found in front of population study #2. They were included in the project, we can always remove them later if we get the photos from HTH.
Other roadkills: many Jerusalem Crickets and centipedes, and a few other arthropods.
Coverage: north part - the county park parking lot till the second stop sign.
Traffic: 6 trucks (including a fire truck), 37 cars, 11 bikes, 15 pedestrians, and 19 cars parked by the road and in the parking lots.
We were behind the HTH team, but we saw them at the end of their route, and we pointed out the newts near #2. We didn't remove the newts, we marked them with rocks (on the side of the road).
The traffic study has been removed. I thought it was supposed to be there fr a while, or at least I expected it to be.
The rowing club was open. All county park parking lots were open.

Pacific Newt Mortality in November

The following charts depict Pacific Newt mortality in the month of November at Lexington Reservoir for four migration seasons. Notice the start of migration is different each year, depending on the cumulative rainfall in the month of November. Also notice the Nov. death toll is much higher this year than in previous seasons. The bars in the second chart mark survey dates (surveys were conducted 1-2 times per week). The arrows indicate the start of migration for each season.

November

December 12, 2020 - south side

29 dead newts (of which 7 were juveniles), 0 live newts.
December 12th, 2020 (Saturday) 9:50am-12pm.
Weather: Overcast low clouds, low-mid 60s. Rained gently the previous night and some scattered light drizzle as I was driving down.
Other roadkill: 1 Arboreal Salamander, 1 Western Toad, 1 large millipede, 1 banana slug (A. buttoni), 1 Striped Skunk (which I didn't try to remove, no thanks)
Coverage: Aldercroft Heights intersection to stop sign.
Rainfall: MTD 0.32in, YTD 1.25in (per http://www.weathercat.net/wxraindetail.php?year=2021)
Traffic: 4 trucks, 36 cars, 9 parked cars, 1 motorcycle, 14 bicycles, 23 walkers.
Pit traps: 10 live newts! First alive newts I've seen in 2020! Also 3 large millipedes and a dwarf tarantula.
The Midpen study area had no newts in their sections of road demarcated by their fences. If they're really doing the 50' either side thing then there was 1 newt in that area, which I reflexively flung into the bushes and couldn't retrieve, so that wasn't so great. It was this one.

All of the newts were very fresh. More of them seemed to be on the east (away from reservoir) side of the road.

December 16, 2020 - South side

December 12th, 2020 (Wednesday) 1:15pm - 3:15pm.
Coverage: Aldercroft Heights intersection to first stop sign.

88 dead newts (of which 6 were juveniles), 0 live newts. A majority were dry, maybe 20% fresh.
Other roadkill: None noticed, aside from the fading skunk.

Weather: Mid 60s, partly cloudy, rain coming tonight.
Rainfall: MTD 1.46in, YTD 2.39in (per http://www.weathercat.net/wxraindetail.php?year=2021)

Traffic: 4 trucks (1 MidPen), 20 cars, 6 bicycles, 0 peds.

Pit traps: No newts, one Darkling Beetle.
There are now pink flags on either side of the pit traps that may be 50' demarcation (looks about right.)

And something odd... Part of the road was recently repaved, so the center lines were re-painted. The line-painter went right over a dead newt which was adhered to the road. I took a photo as they were, then dutifully peeled it off, leaving a shadow that will endure for years. https://www.inaturalist.org/observations/66678920

Weather: Mid 60s, partly cloudy
Rainfall: MTD 1.46in, YTD 2.39in (per http://www.weathercat.net/wxraindetail.php?year=2021)
Coverage: north part - the county park parking lot till the second stop sign.

@merav and me documented 168 dead newts (of which 30 were juveniles). A Handful of newts were really fresh since they had preserved their posture when being run over. The HTH team said they found 5 dead ones near their population study areas but we found there were at least 6 more dead ones that had been lying there for more than a day within the 50 ft of the pitfall traps.

Traffic: 6 trucks, 60 cars, 11 bikes, 6 pedestrians, and 22 cars parked by the road and in the parking lots.
