Plant slope-stabilizing trees on the Mathare valley's upper bank (2026-07-19)

Bare slopes above the Mathare River wash more soil into the channel with every storm, worsening both erosion and downstream flooding. Trees planted on the dry upper slope, well back from the water, hold that soil in place as they establish. Standard: UNEP freshwater ecosystem health guidance; SDG 6.6 Proof: photo of planted trees with species/date Method (UNEP freshwater ecosystem health guidance; SDG 6.6): 1. Confirm the planting spot on the dry upper slope. 2. Dig a planting hole sized to each sapling's root ball. 3. Set each sapling and backfill with native soil. 4. Water each sapling thoroughly from a supplied clean source and mulch the base. 5. Photograph the planted trees and log the species and date. Done when: photo of planted trees with species/date

$160 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 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.
