Case Study #1: Ten newts found in am, only one left by pm

This info was extracted from a comment by @merav. She and I did a team patrol on the morning of Jan 19, 2019. She wrote the following:

" I was there again in the afternoon for a hike, and was surprised to see that almost all the newts we saw in the morning just by the limekiln trailhead were gone. In the morning there were at least 10 dead newts. By 4 pm they were all gone, but 1 that was still there."

In other words, 90% of the dead newts "disappeared" within 8 hrs (8am - 4pm) on a busy weekend by the Limekiln trailhead.

Case Study #2: 64% of dead newts "disappeared" from the road in 4 days

This is an interesting case:

* @sea-kangaroo surveyed the southern half of Alma Bridge Rd. on 1/14/2020 and found 129 dead newts.

* @newtpatrol surveyed the same section of road on 1/18/2020 and found 65 dead newts; 19 of these were fresh, 46 were decomposed

So, one would suppose there would be 129 decomposed newts on the road on 1/18, since there were that many newts reported on 1/14. However, only 46 decomposed newts were found. That means 83 dead newts "disappeared" in the four days between 1/14 and 1/18 (64%). Where did they go?

Migration Patterns of Pacific Newts

Here's the scoop about the newt migration:

"With the first rains in late November or early December, adults emerge from the saturated ground and migrate from their upland habitat to ponds and streams for breeding. Males migrate before females and remain at the breeding site longer...

The female newt lays her fertilized eggs in water where the larvae hatch and grow. Young newt larvae look like frog tadpoles but with longer, thinner bodies. When metamorphosis is complete, the juveniles emigrate from the breeding site and spend the next few years growing to sexual maturity. When they are fully grown, they typically return to the same breeding site year after year to mate.

When the breeding phase is over, females are the first to return to their upland habitat, followed by males and juveniles. However, some adults might remain in the pools for an additional few months to feed. Since the return migration is more sporadic and less weather-dependent than migration to the vernal pools, it is much harder to protect the newts as they make their way back to the forest."

newt survey 1/14 - southern half (Aldercroft)

128 dead newts, 0 live newts.
January 14, 2020 (Tuesday) 1pm-3pm
Weather: Dry and partly cloudy, had rained the previous night.
Other roadkill: 1 Western Grey Squirrel, 1 bird, 1 jerusalem cricket, 3 large millipedes, 1 bullfrog (I think, very pancaked).
Coverage: Aldercroft Heights Road intersection to stop sign.
Rainfall: MTD 0.36in, YTD 12.71in (per http://www.weathercat.net/wxraindetail.php?year=2019)
Traffic: 25 vehicles, 8 bicycles, 1 walker.

About 2 dozen of the newts were fresh-looking, the rest varying degrees of weathered. One of the bicyclers said something unintelligible but friendly about newts while zipping by, so I guess he's talked to one of y'all before.

Help us advocate for the newts!

Dear team,
We've got an opportunity to advocate for the newts this Tuesday - Midpeninsula Open Space District is holding a meeting regarding a parking lot for Sierra Azul Preserve on Alma Bridge Rd. The meeting is on Tuesday, 1/14, 2pm, 17820 Alma Bridge Road, Los Gatos, CA 95033. Please see SCVAS environmental advocate letter about the meeting below -
Merav

On Tuesday's meeting of the MidPeninsula Regional Open Space District (MROSD) Planning and Natural Resources Committee, the committee will discuss the Beatty Parking Area and Trail Connections Project in Sierra Azul Open Space Preserve. The 57-acre Beatty Trust property is located on the easterly side of Alma Bridge Road and Lexington Reservoir approximately 2 miles east of the intersection with Highway 17. The project site is on Alma Bridge Road in an area of high newt mortality.

This is an opportunity to discuss the potential of doing something significant to help the Newts cross the road unharmed

The meeting:
January 14, 2020 - 2:00pm
Meeting Location: 17820 Alma Bridge Road, Los Gatos, CA 95033
Here is the Agenda - The agenda includes a link to the staff report, which is interesting.
This meeting seems to be taking place onsite, outdoors, and it may rain.

I plan to attend the meeting, and I hope we can have a strong presence to advocate for the newts! Please join me if you can, and bring a friend or two. Also - please spread the word!

Thank you,
Shani

newt survey 1/4 - southern half (Aldercroft)

131 dead newts, 0 live newts.
January 4, 2020 (Saturday) 1:45pm-3:15pm
Weather: Dry and partly cloudy, had been dry for more than a week. 57F per my car.
Other roadkill: 1 Jerusalem cricket.
Coverage: Aldercroft Heights Road intersection to stop sign.
Rainfall: MTD 0in, YTD 0in (per http://www.weathercat.net/wxraindetail.php?year=2019)
Traffic: 30 vehicles, 33 bicycles, 2 pedestrians, 1 motorcycle.

I'd still come across "batches" of newts, but overall it seemed like there were more scattered all over the place, and more up on the north side of the big road bend. As always, there were the least on the southernmost portion.
