Clear invasive brush from the Mathare River's dry upper bank (2026-07-20)

Fast-growing invasive brush has taken over stretches of the Mathare River's upper bank, crowding out the native grasses that would otherwise hold the soil in place. Clearing it by hand from dry ground opens room for native planting. Standard: UNEP freshwater ecosystem health guidance; SDG 6.6 Proof: before/after photo of cleared brush Method (UNEP freshwater ecosystem health guidance; SDG 6.6): 1. Confirm the target stretch of dry upper bank. 2. Put on gloves before handling any vegetation. 3. Cut and clear invasive brush using hand tools or power saws at ground level. 4. Bag or stack the cleared material away from the waterline. 5. Photograph the cleared stretch and log the date. Done when: before/after photo of cleared brush

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 30–60 minutes. Method of record: EPA dry-weather / AMD field screening

Bring

• GPS phone
• pH meter or strips
• conductivity meter
• ammonia + iron test kit as specified
• surfactant screen if specified
• gloves
• camera

Steps

1. 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining.
2. 2. Note whether flow is present in dry weather (yes/no).
3. 3. Measure and record pH, conductivity, and each specified analyte per kit instructions.
4. 4. Log any color, odor, floc, or aquatic-life observation.
5. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign.

If it does not match the plan

• Dry-weather flow present with elevated conductivity/ammonia/surfactants -> flag suspected illicit discharge for the responsible agency.
• pH < 6 with visible iron floc -> tag suspected acid mine drainage; recommend metals lab panel.

What counts as done

• pH + conductivity recorded with units
• Each specified analyte recorded with a value
• Dry-weather flow present? recorded yes/no
• GPS waypoint + timestamped photo

Proof is measured against these, not judged by taste.
