Mark a refuge boundary fence span for crane visibility, site 2, the Aransas National Wildlife Refuge boundary fence, accessed from a public county road right of way between Austwell and Tivoli, TX, Refugio County (US Fish and Wildlife Service maintained boundary) (2026-07-30)

The survey above found an un-marked refuge boundary fence span near a marsh flight path used by the wintering whooping crane flock, and hand installed high-visibility marking tags would otherwise leave this collision hazard unaddressed for another season. Standard: USFWS Whooping Crane Recovery Plan collision hazard mitigation guidance plus US EPA National Wetland Condition Assessment rapid method (habitat integrity context), applied here to refuge boundary fence marking near the Aransas National Wildlife Refuge, Austwell and Tivoli, TX, Refugio County, reducing a documented mortality hazard for the wintering whooping crane flock. SDG 15.5. Proof: before after photos plus tag count and span length record plus GPS Method (USFWS Whooping Crane Recovery Plan collision hazard mitigation guidance plus US EPA National Wetland Condition Assessment rapid method (habitat integrity context), applied here to refuge boundary fence marking near the Aransas National Wildlife Refuge, Austwell and Tivoli, TX, Refugio County, reducing a documented mortality hazard for the wintering whooping crane flock. SDG 15.5.): 1. 1. Confirm the fence span is the refuge boundary fence (non-energized wire livestock and boundary fence, never a power line) with US Fish and Wildlife Service refuge staff and photograph the un-marked span before starting. 2. 2. Hand attach high-visibility marking tags to the top wire of the fence span at the labeled spacing, hand tools only, no power equipment. 3. 3. Confirm each tag is securely fastened and clearly visible from the marsh side. 4. 4. Photograph the marked span from the matching before vantage and record the tag count and span length. Done when: before after photos plus tag count and span length 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 tag count and span length 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 45–90 minutes. Method of record: EPA National Wetland Condition Assessment (rapid method)

Bring

• GPS phone
• quadrat frame
• invasive-species ID reference
• boots
• insect protection
• camera

Steps

1. 1. Navigate to the wetland edge; record GPS; stay on stable ground.
2. 2. Photograph 3 quadrat stations.
3. 3. At each station, estimate percent cover native vs invasive; identify the dominant invasive.
4. 4. Note hydrology / water level and any disturbance.
5. 5. Enter cover percentages, invasive ID, hydrology, GPS, photos into the proof record; sign.

If it does not match the plan

• Standing water + wildlife (snakes/alligators) -> maintain distance; never sample alone.
• High invasive cover -> flag for a management/removal plan.

What counts as done

• Percent cover native vs invasive recorded at 3 stations
• Dominant invasive species identified
• Hydrology / water-level note recorded
• GPS waypoints + quadrat photos

Proof is measured against these, not judged by taste.
