Restore a black mangrove fringe gap at Arturo Galvan Coastal Park, site 1, Arturo Galvan Coastal Park, 1801 2nd St, Port Isabel, TX 78578 (public city park, GLO living shoreline project site) (2026-07-29)

The survey above found a bare or invasive choked gap in the black mangrove fringe at Arturo Galvan Coastal Park, and hand cleared, hand planted native mangrove propagules would otherwise close that gap and hold this Lower Laguna Madre shoreline. Standard: NOAA coastal habitat assessment (eelgrass, kelp, and salt marsh extent and condition), applied here to the Lower Laguna Madre hypersaline lagoon system at Port Isabel and Isla Blanca Park, Cameron County, Texas, one of only a few hypersaline lagoon systems on Earth and home to the largest seagrass beds in Texas. SDG 14.2. Proof: before after photos plus propagule count record plus GPS Method (NOAA coastal habitat assessment (eelgrass, kelp, and salt marsh extent and condition), applied here to the Lower Laguna Madre hypersaline lagoon system at Port Isabel and Isla Blanca Park, Cameron County, Texas, one of only a few hypersaline lagoon systems on Earth and home to the largest seagrass beds in Texas. SDG 14.2.): 1. 1. Confirm the fringe segment is public park land and photograph the bare or invasive choked stretch before starting. 2. 2. Hand clear invasive plants from the gap with hand tools only, no power equipment, staying above the waterline. 3. 3. Hand plant native black mangrove propagules at the design spacing along the cleared gap. 4. 4. Photograph the planted fringe from the matching before vantage and record propagule count. Done when: before after photos plus propagule count record plus GPS

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.

Proof

before after photos plus propagule count record plus GPS

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.
