- **Address:** n/CRB2-RR, version 1 of 1 (https://www.plot.eco/n/CRB2-RR)
- **Kind:** Proposal (a recommendation, not a finding)
- **Who said it:** Drafted by AI
- **Period:** as of 2026-10-21
- **Checked:** Reviewed (step 3 of 4): PLOT reviewed the reasoning against the evidence it cites. This is not independent verification, and not an endorsement.
- **Open questions:** None open
- **Proposed by:** Drafted by AI (claude-opus-5-5, via Claude chat, prompt research\_place@1, started by Rob (PLOT owner)); model claude-opus-5-5
- **Barrier:** It is unknown how much of the Ramsar site and the KBA lies inside Hobsons Bay.
- **Proposed action:** Load the official boundaries and compute the overlaps by code, recording them as co-located links with areas.
- **Done when:** Co-located links with overlap areas are on the record, each citing the boundary datasets.
- **Applies to:** Cheetham and Altona Key Biodiversity Area (context), Hobsons Bay (subject), Port Phillip Bay (Western Shoreline) and Bellarine Peninsula Ramsar Site (context)

## Why
- **Reasoning:** A PLOT-side data task; no permission needed. Rests on: ramsar-hobsons-bay-overlap, ramsar-includes-cheetham-parts, kba-includes-cheetham.
- **Assumptions:** Official boundary files are available under a usable licence.
- **Alternatives considered:** Ask DEECA directly; slower.
- **Would change if:** A government source already states the overlap.

## What's blocking this? Jobs (simulated)
- No public jobs.

## Decision log
- No decisions recorded.

## History
- Version 1 (this version): first published version
