I uploaded 191 photos of newts on 1/12 and 1/13. Two photos were of the same newt, the rest were separate observations. Most have them had pretty good coordinates. I didn't change any coordinates. I added coordinates in a few cases, where there was a similar file name, taken on the same date and within a couple of minutes. For other observations missing coordinates, I've asked HTH for more info (33 files, shared on 12/16, 12/29, and 1/8).
I still need to compare the uploaded photos with observations our team made near the HTH sites, to remove all duplicates. If anyone is interested in this task, please let me know. We could also wait a little bit until I'll get the missing photos.

A Pacific Newt population study will be conducted by HT Harvey & Associates in collaboration with Peninsula Open Space Trust (POST) and Midpeninsula Regional Open Space District (MROSD) for the migration season starting late November 2020 and ending sometime between April and May 2021. Daily field operations will be led by a biologist from one of the above agencies paired with volunteers.

The study protocol is considered proprietary (POST asked @merav to review it, but no one else on our team has seen it). However, you can read their public-facing Request for Funding memo (including a map of the study area marking the 6 arrays).

The study objectives are as follows:
"The planned newt population and mortality study will estimate the number of adult newts attempting to cross Alma Bridge Road to breed in Lexington Reservoir and the percentage that are killed by vehicular strikes during a single breeding season. The data will be analyzed through a model to characterize this percentage relative to long-term impacts on the local newt population... The report will also provide daily levels of vehicular traffic and how these levels compare with levels of newt movement. "

The study was prompted by Santa Clara County Roads, Parks, & Water departments who stated that "further study is needed to better understand the issues..."

The HT Harvey analysis of our 2018-2019 roadkill data found "a concentration of mortality along a few road segments" which they deem "Extremely High Mortality." See the map attachment in the above memo. They will install pitfall traps along six 200 ft. sections of road (0.2 mile) for their study. Please be aware that our team has found newt roadkill along all 4.1 miles of our study area. In December, the study team decided to extend the perimeter of their study sites by 50 ft. on each side of the six pitfall traps.

The HT Harvey team started field work building their pitfall traps the week of 10-14-20. Merav spoke with the HTH lead to coordinate the efforts between his team and ours. They committed to share photos of all dead newts found within their study boundaries so that we can compare data with previous years.
