WHAT WOULD CHANGE THIS STATUS?
Survival counts from the split-plot trial after the next monsoon. Clearly higher survival in the treated plots would move this to Resolved; no measurable difference would return it to Open with the approach recorded as unsuccessful.
Every record states in advance what evidence would move it. A status is a current reading of the evidence, not a verdict.
Local context
Community replanting has succeeded in three of five estuary sections. Two sections show repeated seedling loss within the first monsoon.
Who is affected: Four fishing communities using the estuary (synthetic).
Evidence
Evidence summary: Synthetic survey counts and photo series; partially reviewed.
Evidence here does not mean absolute truth. It means: a record exists, with a source, a date and a provenance, and it has reached the review stage shown below.
Seedling survival counts across five sections over two planting seasons.
- Source
- Community survey team (synthetic)
- Evidence submitted
- 20 Jan 2026
- Provenance
- Counts collected by local volunteers using a shared method sheet.
- Evidence reviewed
- 18 Feb 2026
What is needed
- Sediment analysis
- Hydrology modelling
- Species-selection review
- Long-term monitoring support
Proposed solutions
Species substitution in high-energy sections
- What is proposed
- Plant a more wave-tolerant species in the two failing sections.
- Why it might work
- Loss pattern correlates with exposure rather than with planting technique.
- Experience / expertise
- Coastal ecologist (synthetic contributor)
- Supporting references
- General replanting literature.
- What needs testing
- Split-plot trial across one monsoon season.
- Risks / limitations
- Slower canopy formation; possible mismatch with local harvesting practice.
Tests
Split-plot trial running; first results expected after the next monsoon.
