Table 2 Specific framework of habitat risk assessment
Attribute | Score criteriaa | ||
|---|---|---|---|
Low risk | Medium risk | High risk | |
Exposure | |||
Spatial overlay | Habitat and stressor overlay for 0‒20% | Habitat and stressor overlay for 20‒50% | Habitat and stressor overlay for 50‒100% |
Stress intensity | Low intensity | Medium intensity | High intensity |
Consequence–sensitivity | |||
Loss in area | Low loss in area (0‒20%) | Medium loss in area (20‒50%) | High loss in area (50‒100%) |
Change in structure | Low loss in structure (0–20% loss, little to no structural damage) | Medium loss in structure (20–50% loss, partial structural damage) | High loss in structure (50–100% loss, total structural damage) |
Consequence–resilience | |||
Biodiversity of planktonb | Diversity index for 2‒3 | Diversity index for 1‒2 | Diversity index for 0‒1 |
Biodiversity of benthosb | Diversity index for 2‒3 | Diversity index for 1‒2 | Diversity index for 0‒1 |
Management effectiveness | Very effective with the number of marine protection area (> 2) | Somewhat effective with the number of marine protection area (1‒2) | Not effective, poorly managed with no marine protection area |
