Pull invasive cordgrass at a host-led Humboldt Bay workday near Arcata (2026-07-19)

Invasive dense-flowered cordgrass crowds out the native pickleweed and salt grass that Humboldt Bay's shorebirds and juvenile fish depend on, and it spreads along exactly the marsh edges that buffer Arcata from rising water. Hand removal at organized workdays is how the bay's marshes have been held for years, patch by patch. Standard: Humboldt Bay regional Spartina eradication practice under the state Coastal Conservancy program; SDG 14 Life Below Water. Proof: Before/after patch photos with bag count Method (Humboldt Bay regional Spartina eradication practice under the state Coastal Conservancy program; SDG 14 Life Below Water.): 1. Join a host-organized removal workday and take your assigned patch at a low-tide window. 2. Photograph the patch before starting. 3. Working from firm ground, dig out cordgrass clumps by the roots with hand tools and bag all fragments. 4. Carry bagged material to the host's disposal point so no fragments re-root. 5. Photograph the cleared patch and log the bag count and area worked. Done when: Before/after patch photos with bag count

Pay

$340 proposed

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.

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: NOAA coastal habitat (eelgrass / salt marsh) extent + condition

Bring

• tide table
• GPS phone
• quadrat frame
• measuring tape
• boots/waders
• camera

Steps

1. 1. Check the tide table; plan to work the low tide; tell someone your plan and return time.
2. 2. Navigate to the habitat edge; record GPS waypoints along the patch/edge.
3. 3. Photograph the meadow/marsh at low tide.
4. 4. Record shoot/stem density per quadrat and estimate patch extent (or edge scarp height for marsh).
5. 5. Note condition (epiphytes, dieback, wrack) and adjacent land use/armoring.
6. 6. Enter density, extent, condition, GPS, photos into the proof record; sign.

If it does not match the plan

• Soft mud / rising tide -> stop and retreat; safety over data.
• Edge retreat or heavy dieback observed -> flag for living-shoreline / protection planning.

What counts as done

• Density (shoots/stems per quadrat) recorded
• Patch extent or edge position recorded via GPS
• Condition + adjacent-use note recorded
• Low-tide photos + GPS waypoints

Proof is measured against these, not judged by taste.
