Coral fragments planted
coral_planted
| Definition and unit | Coral fragments (nubbins) out-planted on a reef. Monitoring metrics follow the NOAA / Coral Restoration Consortium monitoring guide 2020. |
|---|---|
| Scored unit | fragments (input: fragments) |
| What the weight represents | Reef habitat restoration per surviving fragment. No carbon or monetary value source exists. |
| Weight | 0.4 per fragments |
| Anchor | Weight: none (v0.1 value 0.4 kept). Survival: Boström-Einarsson et al. 2020, PLoS ONE, 60–70% survival across restoration projects; midpoint 0.65. |
| Calculation | fragments × 0.4 × S 0.65 × ESM. Measured survival replaces 0.65. |
| Status | assumption (needs checking). Source: v0.1 value; no carbon or value source for coral fragments |
| Survival factor S | 0.65, sourced. Source: Boström-Einarsson et al. 2020, PLoS ONE: 60–70% survival (midpoint) |
| Multipliers | SM (area factor): no, 1.0. ESM: 1.0 to 1.3, confirmed by a validator. Domain coefficient k: 1.0 (categories not compared). |
| Five Dimensions rubric | depth 2, duration 2, vulnerability 2 (1 to 3 each; proposal for review) |
| Proof that fits | P2 dated underwater photos of the nursery and out-plant site; P3 dive centre or marine park confirmation; P4 survival monitoring data. |
| SDG (contributes to) | SDG-14 |
| v0.1 value | 0.4 per fragments |
Open questions for experts
- Value per surviving fragment relative to a hectare of mangroves.
- Score area of restored reef (m²) instead of fragments?
