Survey the whole Blackwater National Wildlife Refuge observation platform, Cambridge MD for invasive species (2026-07-07)

One boardwalk check isn't the whole wetland. Survey the full accessible area at Blackwater National Wildlife Refuge observation platform, Cambridge MD for native-vs-invasive cover and hydrology so the refuge has a real baseline. Standard: EPA NWCA rapid method; SDG 6.6/15.1 Proof: quadrat photos + GPS + native/invasive cover + hydrology note Method (EPA National Wetland Condition Assessment (rapid method), ~45-90 min): 1. Navigate to the wetland edge; record GPS; stay on stable ground. 2. Photograph 3 quadrat stations. 3. At each station, estimate percent cover native vs invasive; identify the dominant invasive. 4. Note hydrology / water level and any disturbance. 5. Enter cover percentages, invasive ID, hydrology, GPS, photos into the proof record; sign. Equipment: GPS phone, quadrat frame, invasive-species ID reference, boots, insect protection, camera Done when: Percent cover native vs invasive recorded at 3 stations; Dominant invasive species identified; Hydrology / water-level note recorded; GPS waypoints + quadrat photos

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

quadrat photos + GPS + native/invasive cover + hydrology note

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.
