Check the tidal-marsh monitoring plot at South San Francisco Bay Salt Pond Restoration Project, Alviso CA (2026-07-10)

South San Francisco Bay Salt Pond Restoration Project, Alviso CA is a registered tidal-wetland restoration project, but its permanent plot hasn't had this season's accretion, vegetation, and soil-carbon reading taken — without it, the restoration's carbon claim has a gap. Standard: Verra VCS VM0033 tidal wetland/seagrass MRV — soil carbon + accretion + biomass; SDG 14.2. Proof: fixed plot ID + photo-point + accretion reading + paired soil/bulk-density core — Real, Proven, One-of-one Method (Verra VCS VM0033 v2.0 — Methodology for Tidal Wetland and Seagrass Restoration; permanent-plot soil-carbon, biomass/vegetation-cover, and surface-elevation (accretion) monitoring per the project's Sampling and Monitoring Plan., ~90-150 min): 1. Navigate to the permanent plot marker; confirm GPS is within the posting radius and matches the registered plot ID. 2. Photograph the plot from the fixed photo-point bearing, capturing vegetation cover and any visible disturbance. 3. Record percent cover by species within the quadrat frame per the monitoring plan's vegetation protocol. 4. Read the surface elevation table (or measure marker-horizon accretion depth) at each fixed pin/measurement point; record to the nearest millimeter. 5. Extract a soil core to the required depth at the plot's fixed coring point; section by depth interval and bag each section with stratum/plot/depth labels. 6. Collect a paired bulk-density core at the same depth intervals using a known-volume corer. 7. Package sectioned cores with chain-of-custody paperwork for lab analysis of organic carbon and bulk density; note tidal stage and salinity at time of sampling. 8. Enter plot ID, GPS, elevation/accretion readings, cover data, photos, and chain-of-custody number into the proof record; sign. Equipment: GPS-capable phone or survey-grade GPS/RTK, permanent plot markers/PVC monuments, soil corer suitable for saturated tidal sediment (Russian peat corer or push corer), surface elevation table (SET) or feldspar marker-horizon kit, quadrat frame for vegetation cover, sample bags + waterproof labels + cooler, camera, waders/PPE for tidal access Done when: GPS matches the registered permanent plot ID within the posting radius; Fixed photo-point image captured showing vegetation cover and disturbance state; Surface-elevation or marker-horizon accretion reading recorded to the nearest millimeter at every fixed point; Paired soil core + bulk-density core collected at the plot's fixed coring point by depth interval

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 90–150 minutes. Method of record: Verra VCS VM0033 v2.0 — Methodology for Tidal Wetland and Seagrass Restoration; permanent-plot soil-carbon, biomass/vegetation-cover, and surface-elevation (accretion) monitoring per the project's Sampling and Monitoring Plan.

Bring

• GPS-capable phone or survey-grade GPS/RTK
• permanent plot markers/PVC monuments
• soil corer suitable for saturated tidal sediment (Russian peat corer or push corer)
• surface elevation table (SET) or feldspar marker-horizon kit
• quadrat frame for vegetation cover
• sample bags + waterproof labels + cooler
• camera
• waders/PPE for tidal access

Steps

1. 1. Navigate to the permanent plot marker; confirm GPS is within the posting radius and matches the registered plot ID.
2. 2. Photograph the plot from the fixed photo-point bearing, capturing vegetation cover and any visible disturbance.
3. 3. Record percent cover by species within the quadrat frame per the monitoring plan's vegetation protocol.
4. 4. Read the surface elevation table (or measure marker-horizon accretion depth) at each fixed pin/measurement point; record to the nearest millimeter.
5. 5. Extract a soil core to the required depth at the plot's fixed coring point; section by depth interval and bag each section with stratum/plot/depth labels.
6. 6. Collect a paired bulk-density core at the same depth intervals using a known-volume corer.
7. 7. Package sectioned cores with chain-of-custody paperwork for lab analysis of organic carbon and bulk density; note tidal stage and salinity at time of sampling.
8. 8. Enter plot ID, GPS, elevation/accretion readings, cover data, photos, and chain-of-custody number into the proof record; sign.

If it does not match the plan

• Marker horizon buried under far more than the expected annual accretion, or not recoverable -> flag the plot for marker-horizon reinstallation before the next round.
• Vegetation cover drops below the restoration-success threshold in the monitoring plan, or dieback/disturbance is visible -> flag for the project proponent; never average an unflagged anomaly into the reporting period.

What counts as done

• GPS matches the registered permanent plot ID within the posting radius
• Fixed photo-point image captured showing vegetation cover and disturbance state
• Surface-elevation or marker-horizon accretion reading recorded to the nearest millimeter at every fixed point
• Paired soil core + bulk-density core collected at the plot's fixed coring point by depth interval

Proof is measured against these, not judged by taste.
